Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The stack member devices periodically advertise handshake messages, such as hello messages, to ensure that other member devices can identify themselves in the stack topology. The handshake message of the member device is not received within a predetermined time, and the other member devices consider the member device to leave the stack topology.
When announcing the handshake message, each member device in the stack system will send out a hello message through an enabled stack port, and usually one member device includes two stack ports. After other member devices in the stacking system receive the hello message, corresponding device information is extracted according to the content of the hello message, and if the received hello message is sent by the local machine, the hello message is directly discarded; if the message is not sent by the local machine, the message is forwarded.
The stacking system is a logically single system formed by physical cable connection, and the stacking Member devices perform cross-device configuration management and message forwarding in the stacking system according to preset Member numbers (Member IDs). The information transmitted between the member devices in the stacking system is mainly used for controlling information interaction among the devices, so that unified management of the devices in the stacking system is realized conveniently, and a unique management interface and a unique logic processing unit are provided for the outside.
At present, each device of a switch stacking system on the market sends out an announcement message for whole network forwarding, and a message storm is easily caused when a ring topology is not provided with a blocking point. And the TCP mode is generally adopted to exchange messages among the devices, and multiple prepositive message interaction operations need to be completed before actual message interaction, so that the message interaction is complex. In addition, the process for the offline device depends on a timeout mechanism, and the topology convergence is slow.
As shown in fig. 1, a management method for a switch stack system provided in an embodiment of the present application is applied in a switch stack system, where the switch stack system includes a plurality of switches, and the method includes:
s101: initializing the switches, determining identification information corresponding to the switches, and sending heartbeat messages through stacking ports of the switches, wherein the heartbeat messages comprise the identification information and stacking port information.
Initializing a plurality of switch devices in a switch stack system, and setting unique corresponding identification information memberID for each switch according to a preset rule in the initialization process. After the stacking function of the switch stacking system is enabled, a timed sending task of a switch packet receiving and sending module is started, a heartbeat message is sent outwards through an enabled stacking port periodically, and the heartbeat message is terminated when reaching the physical neighbor switch equipment. The physical neighbor switch is a switch directly connected with the switch in a wired manner. The receiving and sending module of the neighbor switch device receives the heartbeat message, and the heartbeat message stores the memberID information and the stacking port information of the received message.
S102: the method comprises the steps of receiving a heartbeat message sent by a neighbor switch through the switch, sending a preparation message to a neighbor management module of the switch according to the heartbeat message, and sending a topology notification message to the neighbor switch through the neighbor management module at regular time according to the preparation message.
Each switch in the switch stack system can send heartbeat messages to its neighbor switches or receive heartbeat messages sent by neighbor switches. The preparation state of the corresponding neighbor switch can be obtained according to the received heartbeat message, and after the preparation state is obtained, the switch transceiving packet module prepares a message ready message to an internal neighbor management module. After receiving ready information of a physical neighbor switch of the packet receiving and sending module, the neighbor management module starts a timing topology notification task of the neighbor management module, and sends a topology notification message To a recorded stack port through a message mechanism of a Transparent Inter-process Communication (TIPC) RDM, wherein the topology notification message carries information of other devices such as unique identification memberID information and interval hop count (Time To Live, TTL) of the switch, and the message is terminated when reaching the physical neighbor.
The TIPC is a network communication protocol for interprocess communication, and is originally designed for inter-cluster communication. It allows designers to create applications that can communicate with other applications quickly and reliably, regardless of the location of other applications requiring communication in a clustered environment. To accommodate user needs, TIPC allows four different communication modes: SOCK _ DGRAM: unreliable unlinked messages; SOCK _ RDM: reliable unlinked messages; SOCK _ SEQPACKET: reliable link-oriented messages; SOCK _ STREAM: the reliable link-oriented byte stream. Because the neighbor messages are sent periodically, the message interaction between the devices can be reduced by adopting the TIPC RDM messages on the premise of ensuring the message reliability.
S103: and extracting the online information of the neighbor switch according to the topology notification message, storing the online information to an equipment information table of the switch, and carrying out topology transmission on the online information in the switch stacking system through the switch.
The device receives a topology notice message sent by a physical neighbor, extracts the unique device identification, the interval hop count and the online stacking port information in the message, stores the unique device identification, the interval hop count and the online stacking port information in a local device information list, and simultaneously sends a device online message to other switches.
In one embodiment, before the timing task of the neighbor management module sends the topology advertisement message, the switch traverses the stored device information list, and obtains the online information through the device information list, so as to determine the online neighbor switch according to the online information. The device information of the on-line neighbor switch is acquired from the stack port (referred to herein as the first stack port) that is connected to the neighbor switch and that sends the message. According to the device information, the online state of the third-party neighbor switch is determined through another stacking port (referred to as a second stacking port) connected with the third-party neighbor switch, and the message can be transmitted to the first stacking port only after the third-party neighbor switch is online. Extracting the device information on the line of the second stack port stored in the device information list, combining the local information and the unique identifier (memberID) information of other devices in the device list, jumping at intervals, modifying the TTL value (for example, adding 1), and sending the device information on the line of the second stack port to the first stack port through a message mechanism of TIPC RDM.
As shown in fig. 2, taking switch number 1(M1) as an example, M1 receives neighbor advertisement messages of number 2(M2) from the second stack port (M1-2) and neighbor advertisement messages of number 5(M5) from the first stack port (M1-1), respectively. Only M2 own device information exists in the neighbor advertisement message of M2 received for the first time, only M5 own device information exists in the neighbor advertisement message of M5, and the online processes of the M2 device and the M5 device are respectively completed through the two messages M1. Subsequently, when the M1 sends a topology advertisement message to the M2 through the M1-2, the message carries local information: the device unique identifier M1, interval hop count TTL 1; and information of M5: the device unique identification M5, interval hop count TTL 2. Through such a neighbor message transfer manner, the M2 device completes the online flow of the M5 device, and completes the topology advertisement transfer to Member3(M3) through its M2-2. By means of the TIPC RDM neighbor advertisement message which is terminated when the message reaches a physical neighbor, on the premise that the message is reliable, message interaction among devices is reduced, and meanwhile, the problem of message storm caused by a loop can be effectively avoided before an optimal blocking point is not set.
In one embodiment, the switch comprises a packet receiving and sending module and a neighbor management module, wherein the packet receiving and sending module is responsible for sending or receiving heartbeat messages, acquiring ready information of the neighbor switch from the received heartbeat messages and sending the ready information to the neighbor management module. The neighbor management module is preset with an online check program for the physical neighbor switch, and the check program utilizes that the packet receiving and sending module continuously does not receive the heartbeat message of the physical neighbor switch which is online in a preset time, namely, the physical neighbor switch is considered to be offline. By adopting the mode of presetting time, the problem that equipment is frequently connected with the line and disconnected from the line due to link oscillation can be reduced, the stability of the stacking system is maintained, meanwhile, the message interaction among internal modules is reduced, and the system pressure is reduced. When the packet receiving and sending module does not continuously receive the heartbeat messages of the physical neighbor switch within the preset time, the device determines that the device is off-line, and then immediately sends an off-line message of the physical neighbor switch to the device management module. The device management module actively sends the offline message of the appointed switch device to other switch devices in the topology by utilizing an TIPC STREAM message mechanism according to the received offline message of the physical neighbor switch, and the offline processing of the device is rapidly completed. Compared with TCP messages, the method reduces multiple handshaking processes before connection establishment, and rapidly notifies other devices in the topology of the offline message on the premise of ensuring the reliability of the message by adopting TIPC STREAM.
In one embodiment, as shown in fig. 3, the present embodiment provides a step of sending a message by a switch device of a switch stack system: after the stacking function is enabled, the packet receiving and transmitting module starts a timing task and sends a heartbeat message which is terminated when reaching a physical neighbor through an enabled stacking port. And judging whether the physical neighbor is ready or not, wherein whether the physical neighbor is ready is set by whether the heartbeat message of the neighbor is received or not. And after the equipment management module judges that the physical neighbor is ready, starting a timing topology notification task. And traversing the equipment information list by the timing task, and extracting the equipment unique identifier (memberID), the equipment survival hop count and the online stacking port from the information list. And sending a topology notification message to a physical neighbor through a message mechanism of a TIPC RDM according to a principle of transmitting equipment information carrying the online of the first stack port and local information to a second stack port.
In an embodiment, as shown in fig. 4, the embodiment provides a task flow of a switch stack system receiving a heartbeat message: after the stack is enabled, starting a heartbeat message receiving mechanism of the physical neighbor switch, and after receiving the heartbeat message of the neighbor switch, setting a ready identifier of the physical neighbor switch to a neighbor management module. If the heartbeat message of the physical neighbor switch is not received, judging whether the neighbor switch equipment is on-line or not, and if not, not processing; if the neighbor switch is on line, starting to judge whether the neighbor switch is in the preset oscillation processing time, if not, considering that the neighbor switch device is off line, and informing the neighbor management module of the device off line. The oscillation processing flow is preset in the processing process, the problem that equipment is frequently brought on and taken off the line due to link oscillation can be solved by adopting a mode of presetting time, the stability of the stacking system is maintained, meanwhile, the message interaction among internal modules is reduced, and the system pressure is reduced.
In an embodiment, as shown in fig. 5, a task flow of a switch receiving topology advertisement message of the switch stack system provided in this embodiment is as follows: after the stacking function is enabled, whether to start receiving a topology notification message is determined according to whether a ready message of a physical neighbor switch is received, wherein the topology notification message mainly processes notification messages and offline messages of the neighbor switch. When receiving the neighbor advertisement message, performing on-line logic processing on the equipment; and when the device offline message is received, processing the device offline message. The on-line logic is used for extracting the equipment unique identifier (memberID), the interval hop count information (TTL) and the on-line stacking port information in the neighbor advertisement message, storing the extracted equipment unique identifier, the interval hop count information (TTL) and the on-line stacking port information into an equipment information list, and providing an on-line message of the switch equipment for other functional modules. The offline processing is to clear the stored equipment information and provide offline information for other functional modules.
