Embodiment Construction

[0032] The principle of the present invention is that: the resource ID of the distributed switch includes a local resource ID and a global resource ID. The CPU of the network management device manages the local resource IDs of all sub-switches of the distributed switch in a localized allocation mode, and each sub-switch defines the resource table information in the mode of WITH_ID or the specified ID according to the local resource ID value assigned by the network management device And create business, that is, the half-side business model, so that the hardware resources of each sub-switch can be efficiently used, and the number of services of the distributed switch is the sum of the capacity of each sub-switch. For some special services, such as pointers used for point-to-multipoint service protection switching, because they involve simultaneous ID synchronization of multiple sub-switches, they must be globalized. At this time, global resource IDs are uniformly planned for all...

Abstract

The invention discloses a resource ID management method and system for a distributed switch, relating to the field of network technology. The method comprises the following steps: network management equipment creates configuration information for a message forwarding service between two sub-switches, and sends the configuration information to the two sub-switches related to message forwarding, wherein the configuration information includes matching parameters and encapsulation parameters of the two sub-switches related to message forwarding as well as local resource IDs, and the local resource IDs are allocated to the two sub-switches related to message forwarding by the network management equipment to identify the matching parameters and the encapsulation parameters; and each sub-switch sets the matching parameters and / or the encapsulation parameters of the message forwarding service according to the received configuration information. According to the resource ID management method and system disclosed by the invention, the local resource IDs do not need to be mutually notified between each sub-switch, the communication load of each sub-switch can be reduced, and thus the message forwarding efficiency and the operation efficiency of the distributed switch can be improved.

Description

[0001] The present invention relates to the field of network technology, in particular to a resource ID management method and system of a distributed switch. Background technique [0002] The sub-switches of each single disk on the switch usually forward services independently, and the encapsulation resource ID allocation in the forwarding resource table of each sub-switch is independent of each other, and no value needs to be specified. In order to meet the increasing demand for switching capacity, multiple physical sub-switches can be logically connected to form a large-capacity distributed switch. The packets between any two ports on the distributed switch are forwarded through a single hop. The arbitrary two ports can belong to different sub-switches. For example, before the ingress sub-switch sends the packet to the specified destination port through the egress sub-switch, The egress sub-switch needs to first create the encapsulation parameters required for encapsulating ...
