Description

ONU service transmission configuration adjustment method, device and equipment

Technical Field

The invention relates to the technical field of passive optical networks, in particular to a method, a device and equipment for adjusting ONU service transmission configuration.

Background

A PON (Passive Optical Network) is a point-to-multipoint Passive Optical Network from an Optical Line Terminal (OLT) to a subscriber terminal (ONU).

The OLT is equivalent to a switch or a router in a traditional communication network, provides an optical fiber interface of a passive optical network facing a user terminal, and realizes the main function of connecting an upper layer network to finish the uplink access of the PON; the OLT is connected with the user terminal ONU through an ODN (optical distribution Network) to realize the functions of controlling, managing, ranging and the like of the user terminal ONU, and the ODN consists of an optical fiber and a passive optical splitter; the main functions realized by the ONU include selecting and receiving data sent by the OLT, responding to a management command sent by the OLT, performing corresponding adjustment, buffering Ethernet data of a user, sending the Ethernet data to an upstream direction in a sending window allocated by the OLT, and the like. The local side remotely controls and manages the upgrading and the configuration of the ONU through the OLT, and in actual use, the PON mainly bears three services of data, voice and video.

In the existing PON system, only a Dynamic Bandwidth Allocation (DBA) method for performing dynamic Bandwidth allocation on an uplink service Bandwidth is defined, and the DBA can complete Bandwidth allocation on queue state information reported by each ONU within a microsecond or millisecond time interval, but this method cannot well meet the needs of practical application, and mainly has the following problems:

1) the action range of the DBA is small, as shown in fig. 1, the DBA only acts on the upstream data transmitted between the PON chip of the OLT and the PON chip of the ONU, but in practical applications, it is necessary to optimize and schedule not only the PON chip, for example, for applications with large bursts, it is necessary to optimize the switch chip of the ONU; for an OLT with a large number of lower-hung ONUs, the switching chip of the ONU may also need to be optimized according to the actual situation; aiming at the problems of packet loss of the switching chip, the total bandwidth of uplink transmission services of a plurality of ONUs exceeding the total bandwidth of the PON uplink and the like caused by various reasons such as packet length, insufficient buffer area and the like of the switching chip, the switching chip and messages which cannot be transmitted in a large burst time slot cannot be processed due to the range limitation of the DBA action, the main borne services cannot be optimized autonomously, and the packet loss condition inevitably exists through the DBA uplink transmission.

2) The DBA has a limited effect, and simply allocates bandwidth to the upstream service of the ONU only according to the state of a buffer (buffer) of a PON chip in the ONU, but cannot identify and optimize the type of the data service.

As shown in fig. 2, when the uplink DBA burst is large, the maximum gigabit bandwidth of the PON port is already exceeded, the DBA cannot adjust the above situation, and the DBA cannot optimize the internal function configuration of the chip, so that packet loss is affected, and the direct phenomenon caused by packet loss is video packet loss and blocking.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.

In practical applications, the PON carries three types of services, namely, main data, voice, and video, each of which has its own characteristics, as shown in table 1:

table 1: different service types and corresponding service features

As shown in fig. 3, the PON system includes a local side device optical line terminal and at least one user terminal device optical network unit, the OLT provides various services such as voice, data, and video to users connected to the ONUs, and the OLT is connected to a network management through an IP network. Specifically, the ONU includes a PON chip and an exchange chip, the PON chip is connected to the OLT, an upstream port of the exchange chip is connected to the PON chip, a plurality of UNI (User Network Interface, User side Network port) are connected to the User terminal device, and similarly, the OLT includes the PON chip and the exchange chip, where one side of the PON chip is connected to the ONU via the PON port and the other side is connected to the exchange chip.

In view of the fact that the existing method for dynamically allocating the upstream service bandwidth defined by the PON system only acts on upstream data transmitted between the PON chip of the OLT and the PON chip of the ONU, but cannot dynamically adjust the processing behavior of the switch chip, and the DBA can only simply allocate the bandwidth for the upstream service of the ONU according to the state of the PON chip buffer of the ONU, cannot identify the type of the upstream service, and cannot dynamically adjust the ONU for different types of upstream services. In view of the foregoing problems, an embodiment of the present application provides an ONU service transmission configuration adjusting method, which is applied to an ONU device, and as shown in fig. 4:

step S401, determining at least one service type carried by the ONU according to the service type of the message transmitted by each port in the exchange chip;

in the embodiment of the present application, the service type forwarded by the switching chip on the ONU device may be used as the service type borne by the ONU device. Specifically, the traffic characteristic information of the message transmitted by each port in the switching chip is collected, the service type of the message transmitted by each port is determined according to the traffic characteristic information of the message transmitted by each port, and optionally, the sum of the types of the service types transmitted by all the ports of the switching chip is used as at least one service type borne by the ONU device, where the service types include a multicast service type, a video service type, a voice service type, and the like.

The collected traffic characteristic information of the packet transmitted by each port in the switch chip is shown in table 2, and may include:

TABLE 2

As an optional implementation manner, the traffic characteristic information of the packet transmitted by each port in the switch chip is obtained, specifically, the register information of each port of the switch chip (for example, an RTL9603C chip, the corresponding register address is 0xBB032600/0xBB032000) can be periodically (default 100ms) read, and the content of the corresponding bit is analyzed according to the preset rule of the switch chip to obtain the traffic characteristic information, where the analysis is the prior art and is not described herein again.

In the process of transmitting service data, the switching chips can forward various service types, such as multicast service, video monitoring service, voice service, and the like, wherein one switching chip can forward only one type of service, and can also forward two or more types of services simultaneously, at this time, some ports on the switching chip forward the video monitoring service, and some ports forward the voice service.

In the following, three service types, i.e., a multicast service, a video monitoring service, and a voice service, are taken as examples to describe in detail how to determine the service type transmitted by each port.

1) Multicast service

In the actual use process of the existing network, when user equipment connected with the ONU in the PON system is a household television live broadcast set top box, terminal equipment installed with live broadcast software and the like, the transmission of multicast services is often involved, and the transmission characteristics of the services are that large-flow multicast service flow exists in the downlink direction. According to the implementation standard required by China telecom EPON equipment, the service implementation needs to follow the interaction of protocol messages, the ONU performs capture analysis on the protocol messages to determine the forwarding of multicast service flow, and by the implementation principle, the number of receiving/sending data frames, the number of receiving/sending multicast frames, the number of receiving/sending packets with different lengths, the multicast local static MAC statistics and the protocol message statistics of receiving/sending in flow characteristic information collected by a port of an exchange chip can be extracted, the multicast configuration mode on the ONU is obtained, and the acquisition of the related configuration parameters of the ONU multicast comprises the following steps: the method comprises the steps of multicasting VLAN, multicasting management mode, multicasting forwarding MAC table, UNI side port service operation type and the like, and judging whether the service transmitted by a port is the multicasting service or not by analyzing the obtained information, and further determining whether the ONU carries the multicasting service or not. Wherein, the concrete judging process comprises the following steps:

determining whether the current ONU supports multicast service according to the multicast related configuration parameters of the ONU;

if the ONU is determined not to support the multicast service, determining that all ports of the ONU do not bear the multicast service;

if the current port does not support the multicast service, determining that the port does not bear the multicast service;

The specific process is as follows, when at least 2 of the following 3 conditions are satisfied, determining that the port transmits the multicast service type message:

a. the average length of the message exceeds the preset byte number (for example 1024);

b. the ratio of the number of the multicast streams to the number of the unicast streams exceeds a first preset proportion;

c. determining that there is interaction of IGMP protocol message;

wherein, whether the ONU and the current port support the multicast service is determined according to the ONU multicast related configuration parameter, which is the prior art and is not described herein again. The average length of the messages, the number of packets of the multicast stream, the number of packets of the unicast stream, and the interaction of the IGMP protocol messages can all be obtained by analyzing the traffic characteristic information of the ports, and the specific analysis process is the prior art. The predetermined number of bytes and the first predetermined ratio may be determined empirically by those skilled in the art.

2) Video monitoring service

When the PON system is applied to a video monitoring scene, video service information is acquired by a camera mounted on User equipment connected to an ONU, and then transmitted to an upper device or a server through the PON system, where the service is mainly characterized in that a TCP (Transmission Control Protocol) message or a UDP (User Datagram Protocol) message with high bandwidth, large flow, large burst, and large packet length exists in an uplink direction. Therefore, the identification of the video monitoring service mainly obtains whether the video monitoring service exists in the port by analyzing the TCP and UDP flows of each port of the switching chip, buffer (buffer area) cache of the switching chip, message length characteristics and the like.

By analyzing the flow characteristic information acquired by the port of the switching chip in real time, when determining that at least 2 of the following 4 conditions are met, determining that the port transmits a message of a video service type, and the specific process is as follows:

a. the proportion of the sum of the uplink flow and the downlink flow occupied by the uplink flow exceeds a second preset proportion (for example, 70%), and the maximum value of the uplink flow is greater than a preset upper limit value;

b. the proportion of the UDP messages and/or the TCP messages in the uplink flow exceeds a third preset proportion;

c. the average length of the message exceeds the preset byte number (for example 1024);

d. the reduction speed of the occupation amount of the forwarding cache corresponding to the port on the switching chip exceeds a preset threshold value.

The second preset ratio, the preset upper limit value, the preset number of bytes, and the preset threshold value may be determined by those skilled in the art according to empirical values. The third preset proportion is a settable threshold, and specifically, the third preset proportion can be set for the purpose of increasing the proportion of UDP messages and/or TCP messages in the uplink traffic, where the calculation of uplink and downlink traffic, the maximum value of uplink traffic, the type of messages mainly in the uplink direction, the average length of the messages, the increase and decrease speed of the occupancy of forwarding cache, and the like, can all be obtained by analyzing traffic characteristic information of the port, and the specific analysis process is the prior art.

Of course, any other known video monitoring service determination algorithm may also be used, and this embodiment does not specifically limit this.

3) Voice service

With the popularization of networks, the use of network telephones and voice services is increasing, and the development of 'light entering and exiting' is gradually achieved in various places. The conversion equipment digitally encodes and compresses the analog signal to package the analog signal into an IP data packet, and transmits the IP data packet in a PON system network. The current protocols followed by voice services in PON systems include h.248 and SIP (Session initiation protocol). In the embodiment of the present application, according to the PON system network voice service and the corresponding characteristics, the specific process includes:

if yes, obtaining a transmission queue corresponding to the message in the designated port number according to port information statistics carried by the voice service type message, and determining that the current port transmits the message of the voice service type when the transmission queue contains the voice message, wherein optionally, the designated port number comprises an SIP: 5060. h.248:2944, finding out the transmission queue corresponding to the message under the appointed port number by the function of chip ACL or Classification.

Step S402, detecting whether to trigger the transmission configuration adjustment of the service under the loaded service type according to the detection mechanism corresponding to different service types;

according to the detection mechanisms corresponding to different service types, it is specifically determined whether the transmission configuration of the service in the ONU meets the transmission capability of the current corresponding service type, for example, when the transmission of the current service reaches the transmission configuration of the service in the ONU or a packet loss condition exists, the service type of the current service is automatically determined, and the transmission configuration adjustment of the service under the loaded service type is triggered.

Step S403, when determining to trigger the adjustment of the transmission configuration of the service under any service type, performing the adjustment of the transmission configuration of the service under the service type according to the adjustment mode corresponding to the service type.

In the embodiment of the application, after the service type of the port of the switching chip is determined, the thread can be independently started to perform optimization (including detection and adjustment) of the transmission behavior of the service of the corresponding type, wherein the adjustment range includes a transmission adjustment range for the switching chip except for the DBA, so that the problem that the video, voice and other information of a user are blocked due to the occurrence of packet loss, congestion and the like in the transmission process of the ONU is reduced or avoided as much as possible, and the purposes of automatic processing and coordinated updating are achieved.

Each service type is corresponding to a respective detection mechanism and adjustment mode to determine whether service transmission configuration adjustment is needed and specifically perform transmission configuration adjustment of the service under the service type, so as to timely prevent and correct service transmission performance deterioration. The detection mechanism and the adjustment mode of different service types are as follows:

1) detection mechanism and adjustment mode corresponding to multicast service

The corresponding detection mechanism and adjustment mode are carried out on the multicast service, so as to more effectively maintain the stability of the on-demand process, the on-demand number performance and the like. After determining that a certain port carries multicast service traffic, if any one of the following conditions is satisfied, triggering adjustment of transmission configuration of a service under a multicast service type:

determining that the downlink flow carrying the current port has a message loss behavior;

and determining that the difference value between the flow in the forwarding buffer corresponding to the current port and the maximum flow which can be borne by the forwarding buffer is smaller than a third preset range. :

the first preset range, the second preset range and the third preset range are configurable parameters, and when the number N of multicast groups requested by a user at a current port approaches the maximum number M of multicast groups supported by the current port, the adjustment of transmission configuration of a service under a multicast service type is triggered, optionally, the first preset range may be set to a range less than 20% of M; when the downlink flow of the current port is close to the service bearing capacity of the port, triggering the adjustment of the transmission configuration of the service under the multicast service type, and when the flow in the forwarding buffer zone corresponding to the current port is close to the maximum flow capable of being borne by the forwarding buffer zone, triggering the adjustment of the transmission configuration of the service under the multicast service type.

The purpose of the detection mechanism further includes determining whether packet loss is possible or has occurred at the bearer port in forwarding of the current service.

Correspondingly, when determining to trigger the transmission configuration adjustment of the service under the multicast service type, performing any one or any more of the following transmission configuration adjustments: adjusting MTU or port capability of the port, starting port flow control, and adjusting size of the port buffer area.

Optionally, in this embodiment of the present application, at least one service feature library is further preloaded, where each service feature library is a set of functions, where each service feature library is used to identify a corresponding service type carried by the ONU, and detect that a transmission configuration adjustment of the service type is triggered, and perform a corresponding transmission configuration adjustment, where the corresponding transmission configuration adjustment includes at least one adjustment method corresponding to each type, the determination method of the service type is determined only by a characteristic of the service itself and is not related to hardware of the device, and the detection mechanism and the adjustment method corresponding to each type include performing pre-adjustment, optimizing a switch chip, a PON chip, and performing service transmission function configuration on the service of the type, so as to enrich a control range of data transmission and ensure that service traffic can be transmitted more efficiently. The detection mechanism and the adjustment method relate to the configuration of registers of the PON chip and the exchange chip, and the part is related to hardware, and corresponding configuration work needs to be realized by calling a specific hardware interface corresponding to a specific chip type.

The at least one service feature library is stored in a linked list, and each linked list node corresponds to one service feature library, as shown in fig. 5.

The following specifically introduces each adjustment method corresponding to each type of service in the embodiment of the present application:

1) adjusting MTU or port capability of a port

The adjustment process includes: checking the reason of the packet loss of the port; if the reason of the packet loss is caused by the self-configured MTU (maximum transmission unit) value of the port or the port rate (transmission rate of data), the following steps are executed:

The detection of the reason for packet loss and the configuration update of the hardware layer belong to the prior art, and are not described herein again.

Example (c): a packet with 129 bytes of packet length can not pass the discard generated because the port MTU value is small when passing the port, the CPU will analyze the packet, and compare the value of 129 with the current port MTU value to obtain that the current port MTU value is less than 129, since the pre-divided packet length intervals are 0-64, 65-127, 128-255, 256-511, 512-1023, 1024-1518, etc., it can be seen that 129 belongs to the 128-255 interval, the system will configure the MTU value to be 255.

The above adjustment method is described below with reference to a specific embodiment, as shown in fig. 6:

step S601, obtaining the actual transmission rate of the current port transmission message and the message packet length of the packet loss;

step S602, acquiring port transmission rate and MTU value currently configured by a port;

step S603, determining whether the transmission rate configured by the port is less than the transmission rate of the actual transmission packet of the current port, if so, executing step S604, otherwise, executing step S606;

step S604, configuring the transmission rate of the port to be not less than the actual transmission rate of the current port;

step S605, configuring corresponding parameters of a hardware layer by calling a system interface according to the reconfigured transmission rate;

step S606, judging whether the MTU value configured by the port is smaller than the packet length of the current port transmission message, if so, executing step S607;

step S607, configuring the MTU of the port to be not less than the maximum packet length of the packet loss of the current port;

step S608, configuring corresponding parameters of the hardware layer by calling the system interface according to the reconfigured MTU.

2) Open port flow control

And when the residual size of the port buffer area is judged to be smaller than the preset cache threshold value, suspending the interaction of pause frames through flow control, and reducing the flow of the message at the sending end.

When the service message bursts and the flow is large, and the common port burst in a short time is larger than the port configuration transmission rate and the packet loss can not be solved by adjusting the port transmission rate, the transmission configuration adjustment and optimization can be continued, and the flow of the service message at the sending end is restrained by controlling the interaction (network flow control) of pause frames. Specifically, by judging whether the remaining size of the port buffer is smaller than a preset cache threshold, if it is determined that the remaining size of the port buffer is smaller than the preset cache threshold, a flow control pause frame is generated, configuration related parameters (port, flow control enable, access direction) are generated, a system software interface is called, the hardware flow control function is started, and correct forwarding during service burst is ensured.

The MTU or port capability of the port is adjusted, the flow control of the port is started, the problem of packet loss possibly existing in the PON system is solved or prevented by automatically identifying the service type, adjusting equipment configuration, equipment service capability and the like, the self-checking and correcting measures when the packet loss exists in a switching chip under the condition that the DBA is normally used can be solved, the limitation of the effective range of the DBA is made up, and the normal forwarding of the service is ensured as much as possible.

3) Adjusting QOS priority queues

And improving the priority of the queue for storing the IP-based voice transmission type message in the QOS priority message queue.

When the PON system carries high priority services such as VOIP (Voice over Internet Protocol, Voice over IP) Voice, in order to ensure transmission of the high priority services as much as possible, a QOS priority packet queue may be set, and by increasing the priority of the queue for storing VOIP Voice type service flows, the processing and forwarding speeds of packets in the queue are increased, so as to prevent the problem of congestion and packet loss that may exist in transmission of packets with priority. A QOS priority queue and rule are created, a compliance basic model is shown IN fig. 7, wherein when a message enters a port, classification is performed first, the classification process mainly checks a packet and configures a low-cost QOS tag according to an ACL (access control list) or a configuration policy, and then determines whether the packet is an IN profile (IN identifier) or an OUT profile (OUT identifier) according to a Rate of a policy comparison flow. Determining and marking the processing action of the packet according to whether the packet is an IN profile or an OUT profile, specifically comprising passing, modifying or discarding, then determining an IN-queue for the packet to enter according to the QoS label of the generated packet, and processing the packet according to the weight set by the priority of the packet, and when the packet is OUT-port, determining an OUT-queue for the packet to enter according to the QoS label of the generated packet, and processing the packet according to the weight set by the priority of the packet.

4) Adjusting buffer size of a port

And the size of the buffer area is adjusted by configuring and updating packet loss conditions of the outgoing direction and the incoming direction of the message transmitted by the port.

The adjusting action can configure and update packet loss conditions of an outgoing direction and an incoming direction of a message transmitted by a port, taking an RTL960X series chip as an example, parameters such as Page Count, Drop-Threshold and the like of the configured port can be adjusted, and a reasonable numerical value can be allocated to a specific adjusted value through statistics and packet loss comparison, so that hardware resource allocation of each port under the current service is comprehensively adjusted to provide more buffer areas as much as possible to prevent data loss under the conditions of packet loss, burst and extreme value of the port service, the part of loss is loss of switching to a PON, and a port flow control comparison method is used for realizing the purpose of improving the switching forwarding performance of equipment when a flow control function is not started. It also presents the limitations of DBA in use: the packet loss behavior of other parts outside the PON system cannot be guaranteed.

5) Adjusting the Ethernet frame length in the message

The current type service refers to a service type corresponding to transmission traffic of a current port, and specifically may include a multicast service type, a video service type, a voice service type, and the like, and the trunk mode may be to mark a preset VLAN tag on a message without the VLAN tag.

The adjustment action for reducing the message length mainly aims at the situation that the flow is large when the small byte packet length exists, and through the action operation, the occupation of the uplink bandwidth is reduced, and more resources are provided for a PON system in transmission.

Specifically, the length of the transmitted message is reduced by shortening the byte length of the header ethernet frame of the message, and the VLAN of 802.1q in the header ethernet frame of the message is mainly removed, so that the length of the message can be transmitted in the same time slot with the byte number of a smaller flow, and the occupied bandwidth is small. Therefore, data with a certain information amount can be realized by a short packet length, and performance optimization is improved.

The implementation of the process mainly uses the basic characteristics of the network protocol IEEE802.1 q. In network transmission, the packet format of data encapsulation is composed of ethernet frame, IP, data, and check code, as shown in table 3:

TABLE 3

ETHERNET frame header

IP header

TCP head

Data of

FCS

For the two-layer transmission of the PON system, the vlan of ieee802.1q is most used in the large-scale use of the existing network, so the ETHERNET header can be modified according to the actual PON system configuration. The adjusting method is to reduce the length of the header of the packet by using the principle of removing the vlan of 802.1q, and the header of ETHERNET mainly contains information as shown in table 4:

TABLE 4

DMAC

SMAC

802.1Q tag

Type

data

The 802.1Q Tag includes 4 bytes of Information including a 2-byte TPID (Tag Protocol Identifier) and a 2-byte TCI (Tag Control Information), and according to the actual configuration of the PON system, the portion may actually occupy 4 bytes or 8 bytes (double Tag), and for a minimum 64-byte message that can be transmitted, the length of 4 bytes may be reduced by deleting the 802.1 Tag. In the process, VLAN configuration needs to be coordinated, namely VLAN configuration of the ONU and the OLT is changed, and upper network configuration is agreed.

The method for adjusting the length of the ethernet frame in the message is described in detail below with reference to a specific embodiment, where port VLAN configurations consistent with the current ONU exist in all port VLAN configurations of all other ONUs of the OLT connected to the current time, and at this time, VLAN configurations of the current ONU, the corresponding OLT, and all other ONUs connected to the OLT need to be changed, as shown in fig. 8:

step S801, initiating a query request for system VLAN configuration information to an OLT, and receiving a response fed back by the OLT aiming at the query request;

wherein the response includes the following information: the VLAN mode of the PON port of the PON chip on the OLT, the VLAN configuration of the PON port of the PON chip on the OLT, and the VLAN configuration of all ports of each ONU under the PON port of the PON chip on the OLT.

Step S802, determining that port VLAN configurations consistent with the ONU exist in all the port VLAN configurations of all other ONUs connected with the OLT in the received response;

step S803, obtain the goal VLAN of UNI port of the business of transmission current type on the exchange chip;

step S804, removing the acquired target VLAN in the VLAN configuration of the upper connection port of the exchange chip;

step S805, determining that the configuration modification result is obtained by modifying the VLAN mode of the PON port of the PON chip on the OLT and the VLAN configuration of the PON port of the PON chip on the OLT;

wherein the modifying operation comprises: updating the VLAN mode configuration of a PON port of a PON chip on the OLT into a trunk mode, and setting the VLAN configuration in the trunk mode as follows: PVID is a target VLAN, and the trunk mode marks a preset PVID label on a permitted message without the label; the VLAN allowed to pass through is deleted from the same VLAN as the target VLAN, and the rest remains.

Step S806, sending the configuration modification result to the OLT to instruct the OLT to update the VLAN configuration of the PON port of the OLT and correspondingly modify the VLAN configuration of other ONUs;

and correspondingly modifying the VLAN configuration of other ONUs, specifically informing the port VLAN configuration under the PON port of the PON chip that the VLAN configuration related to the target VLAN is adaptively modified by the other ONUs of the target VLAN, namely removing the target VLAN in the VLAN configuration of the uplink port on the switching chip by the other ONUs.

Step S807, the exchange chip forwards the message internally according to the configuration and reduces the message length, and the message is sent to the OLT through the PON chip;

after a UNI port transmitting the current type service on an exchange chip of the ONU receives a message sent to upper-layer equipment of the PON system, a target VLAN label is marked on the message, and the message is forwarded to an uplink port of the exchange chip through the target VLAN; after the target VLAN tag is stripped at the upper connector, the target VLAN tag is sent to a PON chip of the ONU and sent to the OLT through a DBA mechanism.

In this way, after the PON port of the PON chip on the OLT receives the message, and detects that the VLAN tag does not exist in the message, a target VLAN tag is added to the message according to the PVID, and subsequent processing is performed.

As an optional implementation method, the method for adjusting the length of the ethernet frame in the message, where there is no port VLAN configuration that is consistent with the current ONU in all port VLAN configurations of all other ONUs including the OLT currently connected to the current ONU, and at this time, only the VLAN configurations of the current ONU and the corresponding OLT need to be changed, as shown in fig. 9, includes:

step S901, obtaining a target VLAN of a UNI port for transmitting the current type service on a switching chip;

step S902, removing the obtained target VLAN in the VLAN configuration of the uplink port of the exchange chip;

step S903, determining that the configuration modification result is obtained by modifying the VLAN mode of the PON port of the PON chip on the OLT and the VLAN configuration of the PON port of the PON chip on the OLT;

wherein the modifying operation comprises: updating the VLAN mode configuration of a PON port of a PON chip on the OLT into a trunk mode; the VLAN configuration in this mode is set to: PVID is a target VLAN; the VLAN which is the same as the target VLAN in the allowed VLAN is deleted, and the rest is still reserved;

step S904, sending the configuration modification result to the OLT, so as to instruct the OLT to update the VLAN configuration of the PON port of the OLT, and synchronously update the VLAN configuration under the PON port of the local PON chip;

step S905, the exchange chip forwards the message internally according to the configuration and reduces the message length, and the message is sent to the OLT through the PON chip;

The specific process described above is illustrated in fig. 10 and 11.

6) Adjusting message frame spacing

Aiming at the realization of the inter-frame interval of the message, the adjustment of the interval between the message frames can be completed by calling the specific register instructions of different chips, and the message transmission rate is improved by shortening the IFG (Interframe Gap) time so as to send more data in the specific time slot of the ONU. The following provides a practical operation in which the slot interval can be adjusted. As shown in Table 5, for a chip, the adjustable value of the frame gap is:

TABLE 5

The method for triggering the adjustment of the transmission configuration of the services under different service types covers the limitation of DBA sending processing, can realize the joint processing between the exchange chip and the PON chip, and can be flexibly applied to various scenes.
