Embodiment 1

[0045] The data flow processing method in the distributed link aggregation network according to Embodiment 1 of the present application may be applied to any one of the two devices in the distributed link aggregation. Such as figure 2 As shown, the method includes the following steps:

[0046] Step S202, adding all DT ports belonging to the distributed aggregation group on the device to the local aggregation group;

[0047] In actual implementation, for a distributed aggregation group, there may be only one DT port belonging to the distributed aggregation group on the network device (this case is called case 1), or there may be multiple (this case is called case 2) Whether it is case 1 or case 2, all DT ports belonging to the distributed aggregation group on the device are added to a local aggregation group, and the aggregation group ID of the local aggregation group is the same as the aggregation group ID of the distributed aggregation group. The group ID is irrelevant. I...

Embodiment 2

[0121] by figure 1 The shown SW2 in the distributed link aggregation network is taken as an example to illustrate the method in the first embodiment above. exist figure 1 , ports Port1 and Port2 on switch SW2, and ports Port4 and Port5 on SW3 are added to the same distributed aggregation group 1; ports Port3 on SW2 and port Port6 on SW3 are added to the same distributed aggregation group 2 middle. An ISC link is connected between SW2 and SW3, the ISC port connected to the ISC link on SW2 is ISCPort1, and the ISC port connected to the ISC link on SW3 is ISCPort2.

[0122] For distributed aggregation group 1, the methods performed by SW2 include:

[0123] Step S602, add Port1 and Port2 to a local aggregation group, the ID of the local aggregation group is recorded as 3; specifically, add a table containing the aggregation group ID3 and its corresponding member port list to the aggregation group information table items, as shown in Table 3-1:

[0124] Table 3-1

[0125] ...

Embodiment 3

[0152] The embodiment of the present application proposes a data stream processing scheme to realize fast switching of data streams when all DT ports belonging to a distributed aggregation group on the device are DOWN, and to solve the problems existing in the prior art that are relatively time-consuming and affect data Flow switching performance wastes network bandwidth resources and affects CPU processing performance and normal data forwarding.

[0153] Taking software implementation as an example, in a preferred implementation mode, the embodiment of the present application provides a data link that can be applied to any one of the two network devices of the distributed aggregation in the distributed link aggregation network. Stream processing device.

[0154] Such as image 3 As shown, the data stream processing device 10 includes the following modules: a local aggregation group joining module 101, a receiving module 102, an outgoing interface determining module 103, an e...

Abstract

The present application discloses a data flow processing method and device in a distributed link aggregation network, wherein the method includes: adding all DT ports belonging to the distributed aggregation group on the device to the local aggregation group; receiving After the unicast message, determine the outgoing interface of the unicast message according to the MAC forwarding table; if it is determined that the outgoing interface of the unicast message is a local aggregation group, then find the member corresponding to the local aggregation group from the aggregation group information table port list, and forward the unicast message according to the member port list; wherein, when the DT port belonging to the distributed aggregation group on the device has only one first DT port, the member port list is the first DT port; when the device belongs to When there are at least two DT ports in the distributed aggregation group, the member port list is the at least two DT ports; when the local aggregation group becomes DOWN, the member port list is modified to the ISC link connected to the device. ISC port.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a data stream processing method and device in a distributed link aggregation network. Background technique [0002] IRF (Intelligent Resilient Framework) technology can combine multiple switching devices into a high-performance whole, with the purpose of obtaining the highest possible network performance and network availability with as little overhead as possible. Devices that support IRF technology have three important features: Distributed Device Management (DDM), Distributed Link Aggregation (Distributed Link Aggregation, DLA; or Distributed Trunking, DT) and Distributed Resilient Routing (DRR). These three technologies are indispensable to accomplish the technical goals of IRF. Among them, DT is used to improve the availability and capacity of the transmission link. [0003] In common link aggregation technology, only ports on the same device ca...
