Description

Configuration method and device for FIC ID of line card equipment of router

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring an Identity (ID) of a Fabric Interface Chip (FIC) of a line card device of a router.

Background

With the increasing abundance of network service types and the increasing demand of operator networks/data center networks on throughput, the traditional router breaks through the limitation of the subrack and develops into a scale-out (scale-out) router. The scale-out router consists of three parts, namely: the system comprises a server, a switching device and a line card device.

Data transmission between the line card devices is performed based on the FIC IDs of the line card devices, and therefore, the FIC ID of each line card device must satisfy uniqueness. In the full in-band management mode, a server configures the FIC ID of each line card device, and in the prior art, in the process of configuring the FIC ID of each line card device, the server performs hash operation on a Serial Number (SN) or a Media Access Control (MAC) address of the line card device to obtain an initial FIC ID of the line card device, and configures the FIC ID of the line card device based on the initial FIC ID of the line card device, where the SN or the MAC address of the line card device is an inherent factory value of the line card device.

However, the length of the FIC ID is fixed, and the maximum length is about 10 bits, so that within a limited length, there may be a problem of hash collision, that is, the initial FIC IDs of two different line card devices obtained by using the prior art may be the same, thereby reducing the reliability of the configuration of the FIC IDs of the line card devices.

Detailed Description

In the embodiments of the present application, "and/or" is only one kind of association relation describing an association object, and means that there may be three kinds of relations. For example, a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the present application, "a plurality" means two or more than two.

In the embodiments of the present application, a certain network element (e.g., an a network element) acquires information from another network element (e.g., a B network element), which may mean that the a network element receives information directly from the B network element, or that the a network element receives information from the B network element via another network element (e.g., a C network element). When the network element a receives information from the network element B via the network element C, the network element C may transparently transmit the information, or may process the information, for example: and carrying the information in different messages for transmission or screening the information, and only sending the screened information to the network element A. Similarly, in the embodiments of the present application, the sending of the information by the network element a to the network element B may refer to the sending of the information by the network element a directly to the network element B, or may refer to the sending of the information by the network element a to the network element B via another network element (e.g., a network element C).

Fig. 1 is a schematic diagram of a structure of a scale-out router provided in the present application, and as shown in fig. 1, the scale-out router of the present application includes: the system comprises a server, switching equipment and line card equipment, wherein the switching equipment forms a switching network, and the server communicates with the line card equipment or the line card equipment through the switching network.

The paths between the switching devices and the line card device form a data transmission channel. The data transmission channel comprises two types of chips, namely an FIC (Fic) chip and a Switch Fabric (SF), wherein the FIC chip is identified by a unique FIC ID, and the SF is responsible for exchanging data among a plurality of FICs. The FIC is located at the line card equipment, the SF is located at the exchange equipment, the 1 SF chip can be connected to the 1 FIC chip through one or more pairs of receiving and transmitting paths, and load sharing is carried out among the multiple pairs of receiving and transmitting paths. Therefore, multiple reachable paths may exist between the server and the line card device or between the line card device and the line card device, and the switching network selects the paths for communication in a load balancing manner during data forwarding.

In fig. 1, communication is performed between a server and a line card device, or between a line card device and a line card device, based on FIC IDs.

The Scale-out router supports flexible expansion and plug and play of the line card equipment or the switching equipment, and the technical scheme of the application is applied to a scene how the server configures the FIC ID for the line card equipment when the line card equipment is not configured with the FIC ID (for example, when the line card equipment is initially powered on).

The technical solutions of the present application are described below with several embodiments as examples, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 2 is a schematic flowchart of a method for configuring an FIC ID of a line card device of a router according to the present application, as shown in fig. 2:

s201: and the line card equipment sends a request message.

And the line card equipment sends a request message to the server through the switching network.

The request message includes identification information of the line card device and a first FIC ID of the line card device, and the request message is used for requesting allocation of a second FIC ID for the line card device.

The first FIC ID is a default value, and the default values of the first FIC IDs of different line card devices may be the same or different, for example: the default value of the first FIC ID of all the line card devices may be K0; or, the default values of the first FIC ID of the line card device with SN1, … … and SN 100 are all K1, and the default values of SN101-SN200 are all K2, which is not limited in this application.

The second FIC ID is an FIC ID allocated by the server to the line card device.

For example: one format of the request message is shown in table 1:

TABLE 1

SN＝102

First FIC ID K2

In a period of time, there may be a plurality of line card devices with the same first FIC ID that all send request messages to the server, and assuming that N line card devices with the same first FIC ID send request messages to the server, the server receives N request messages, and the server performs S202.

S203: the server generates a response message.

In order to avoid that the response message is divided, the length of the response message cannot exceed the maximum length of a single cell, and therefore, the number of configuration information of the line card device carried in the response message is limited, the present application takes as an example that the response message can carry configuration information of S line card devices at most, where S is an integer greater than or equal to 1.

When the number N of the request messages received by the server is greater than S, the response message includes first configuration information, second configuration information, and a first FIC ID, the first configuration information in the response message carries identification information of the S line card devices and a second FIC ID corresponding to the identification information of each line card device, and the second configuration information carries at least one proposed FIC ID.

The response message specifically carries configuration information of which S line card devices of the N line card devices, which is not limited in the present application, for example: the S line card devices received first may be selected according to the order of receiving the request message, or the S line card devices with the highest priority may be selected according to the priority of the line card devices, or the S line card devices may be selected at random, and so on.

For example: one format of the response message is shown in table 2:

TABLE 2

When the number N of the request messages received by the server is less than or equal to S, the response message includes first configuration information, second configuration information, and a first FIC ID, the first configuration information in the response message carries identification information of the N line card devices and a second FIC ID corresponding to the identification information of each line card device, and a proposed FIC ID carried in the second configuration information is null.

For example: one format of the response message is shown in table 3:

TABLE 3

S205: the server sends a response message.

The server sends a response message to the line card equipment through the switching network, and the switching network sends the response message to the line card equipment corresponding to the first FIC ID in a load balancing mode.

S207: and the line card equipment determines the second FIC ID of the line card equipment according to the response message.

Because the switching network sends the response message to the line card device corresponding to the first FIC ID in a load balancing manner, any line card device corresponding to the first FIC ID may receive the response message.

Aiming at the line card equipment receiving the response message:

if the first configuration information includes the identification information of the line card device, determining that a second FIC ID corresponding to the identification information of the line card device in the first configuration information is a second FIC ID of the line card device, and combining table 2, for example: the line card device with SN of 1 receives the response message, the first configuration information of the response message includes identification information of the line card device with SN of 1, and the line card device determines that the second FIC ID corresponding to SN of 2 in the first configuration information is 001 of the second FIC ID of the line card device, and modifies the FIC ID of the line card from K2 to 001.

If the first configuration information does not contain the identification information of the line card device, determining that one FIC ID in at least one suggested FIC ID in the second configuration information is the second FIC ID of the line card device. In conjunction with table 2, for example: the line card device with the first FIC ID of K2 and the SN of S +1 receives the response message, the first configuration information of the response message does not include the identification information of the line card device with the SN of S +1, and the line card device determines that one FIC ID of at least one proposed FIC ID in the second configuration information is the second FIC ID of the line card device, and if it is determined that K3 is the second FIC ID of the line card device, modifies the FIC ID of the line card device from K2 to K3. When there are multiple proposed FIC IDs, one of the proposed FIC IDs may be selected in a random selection manner, or one of the proposed FIC IDs may be selected in a hash operation manner on SN or a MAC address, which is not limited in this application.

In this embodiment, a request message is sent to a server by a line card device, the request message carries identification information of the line card device and a first FIC ID, the server receives the request message sent by a plurality of line card devices with the same first FIC ID, according to the number of the received request messages, knows the number of line card devices with conflicting first FIC IDs, allocates a second FIC ID to some of the line card devices according to the identification information of the line card devices carried in the received request message, generates a response message, the response message includes identification information of some line card devices and corresponding second FIC IDs, and proposes FIC IDs, the line card device receiving the response message determines that the second FIC ID corresponding to the identification information of the line card device in the response message is the second FIC ID of the line card device if the response message includes the identification information of the line card device, if the response message does not contain the identification information of the line card device, determining that one FIC ID in the at least one suggested FIC ID in the response message is the second FIC ID of the line card device. Any line card device receiving the response message can modify the FIC ID of the line card device, so that the collision of the FIC IDs of the line card devices is reduced, and the reliability of the configuration of the FIC IDs of the line card devices is improved.

Fig. 3 is a schematic flowchart of a configuration method of FIC IDs of a line card device of another router provided in the present application, where fig. 3 is based on the embodiment shown in fig. 2, optionally before S203, further includes S202a and S202b, and after S207, further includes: s208 to S211, as shown in FIG. 3:

s201: and the line card equipment sends a request message.

S202 a: and the server stores the identification information of the line card equipment contained in the N received request messages in an application pool corresponding to the first FIC ID according to the identification information of the line card equipment contained in the request messages and the first FIC ID of the line card equipment.

The server establishes an application pool, and maintains the number of line card devices and the identification information of the line card devices aiming at FIC ID conflicts corresponding to the application pool through the application pool

The method for establishing the application pool by the server includes, but is not limited to, the following methods:

one possible implementation:

the server creates an application pool, wherein the application pool can correspond to a plurality of FIC IDs; when the identification information of the line card device is stored in the application pool, storing the corresponding relationship between the identification information of the line card device and the FIC ID, as shown in reference 4:

TABLE 4

First FIC ID	Identification information of line card equipment
		K1	SN＝1
K1	SN＝5
		K2	SN＝101
K2	SN＝102

Another possible implementation:

the server creates application pools corresponding to different FIC IDs, and stores identification information of the line card device in the application pool corresponding to the first FIC ID, as shown in table 5 and table 6, where table 5 is the application pool corresponding to the first FIC ID K1, and table 6 is the application pool corresponding to the first FIC ID K1

The first FIC ID is an application pool corresponding to K2:

TABLE 5

TABLE 6

Identification information of line card equipment
	SN＝101
SN＝102

S202 b: and the server allocates a second FIC ID corresponding to the identification information of the S line card devices in the application pool.

The application is described by taking the configuration information of S line card devices which can be carried by the response message at most as an example, and when N is greater than S, the server allocates FIC IDs corresponding to the identification information of the S line card devices in the application pool.

S203: the server generates a response message.

S205: the server sends a response message.

S207: and the line card equipment determines a second FIC ID of the line card equipment according to the response message.

S208: and the line card equipment sends an acknowledgement message.

And the line card equipment receiving the response message sends a confirmation message to the server through the switching network.

The confirmation message includes the identification information of the line card device and the second FIC ID of the line card device.

For example: one format of the acknowledgement message is shown in table 7:

TABLE 7

SN＝1	Second FIC ID 001

S209: and the server deletes the identification information of the line card equipment contained in the confirmation message from the application pool.

And the server deletes the identification information of the line card equipment contained in the confirmation message from the application pool corresponding to the first FIC ID. That is, the line card device sending the acknowledgement message does not conflict with the FIC IDs of other line card devices in the application pool corresponding to the first FIC ID.

S210: and the server stores the identification information of the line card equipment contained in the confirmation message and the second FIC ID of the line card equipment in an allocation pool.

And the server establishes a distribution pool, and maintains the number of the line card devices which are distributed with the FIC ID and the identification information of the line card devices through the distribution pool. And the FIC IDs of the line card devices in the allocation pool do not conflict.

One possible implementation of the allocation pool is shown in table 8:

TABLE 8

SN＝1	Second FIC ID 001

Optionally, the allocation pool may further include a recovery remaining time, which is a longest time interval for the line card device to reply the keep-alive message, as shown in table 9:

TABLE 9

SN＝1

Second FIC ID 001

Timeout＝450

S211: the server sends a first keep alive message.

And the server sends a first keep alive message to the line card equipment which sends the confirmation message through the switching network.

The first keep alive message includes the line card device identification information, the second FIC ID corresponding to the line card device identification information, and the recovery remaining time of the second FIC ID.

For example: one format of the keep-alive messages is shown in table 10:

watch 10

SN＝1

Second FIC ID 001

Timeout＝450

Since the FIC IDs are scarce resources, in order to improve the utilization rate of the resources, if the second keep-alive message sent by the line card device corresponding to the second FIC ID is not received before the recovery remaining time arrives, it means that the line card device corresponding to the second FIC ID does not use the FIC ID in the period of time, and then the second FIC ID is recovered. If the second keep-alive message sent by the line card device corresponding to the second FIC ID is received before the recovery remaining time reaches, which means that the line card device corresponding to the second FIC ID expects to continue using the FIC ID, the recovery remaining time of the second FIC ID is reset.

Two cases follow S211: one is S212 to S213; the other is S213'.

S212: before the recovery residual time of the second FIC ID is reached, the line card equipment sends a second keep-alive message to the server;

s213: the server resets the recycling remaining time of the second FIC ID.

The second keep-alive message includes identification information of the line card device and a second FIC ID corresponding to the identification information of the line card device, and the second keep-alive message is used for requesting to reset the recovery remaining time of the second FIC ID.

And when the recovery remaining time of the second FIC ID is up, the second keep-alive message sent by the line card device is not received, and S213' is executed.

S213': and the server deletes the identification information of the line card equipment and the second FIC ID of the line card equipment from the allocation pool.

The server maintains the number of the line card devices of the assigned FIC IDs and the identification information of the line card devices through the allocation pool, and thus, the second FIC ID can be recovered by deleting the identification information of the line card devices and the second FIC ID of the line card devices from the allocation pool.

After the line card device receives the first keep alive message, recording the recovery remaining time of the second FIC ID and the current time T1 of the line card device, when the line card device is restarted for some reason, detecting whether the time interval between the current time T3 and the current time T1 recorded before restarting is larger than the recovery remaining time of the second FIC ID after restarting, and if the time interval is larger than the recovery remaining time of the second FIC ID, setting the FIC ID of the line card device to be modified from the second FIC ID to the first FIC ID, namely to be modified to be the default FIC ID.

The detailed descriptions of S201, S203, S205, and S207 refer to the corresponding steps in the embodiment shown in fig. 2, and are not repeated here.

In this embodiment, on the basis of the embodiment shown in fig. 2, the number of line card devices with FIC ID conflicts and identification information of the line card devices are maintained through an application pool; maintaining the number of the allocated FIC ID line card equipment and the identification information of the line card equipment through a distribution pool; thus, it is convenient to manage the assignment of FIC IDs.
