Based on this, after the PE device receives the packet, if the outbound port corresponds to ECID100 in namespace 2, but the PE device only knows that the inbound port corresponds to ECID1, but cannot know whether the inbound port corresponds to ECID1 in namespace 1 or ECID1 in namespace 2, In this way, the PE device cannot know whether to forward packets through the port corresponding to ECID100 or to filter packets, resulting in packet processing errors

Abstract

The present application provides a message processing method and device, the method comprising: receiving a first message sent by a PE device; determining the namespace of the PE device and the first extended channel through which the first message enters the ingress port of the network side identification, the second extended channel identification of the outgoing port where the first message leaves the network side; encapsulate the extended label header for the first message to obtain a second message; the extended label header includes the namespace, the The first extended channel identifier and the second extended channel identifier; sending the second message to the PE device where the egress port is located, so that the PE device where the egress port is located is based on the namespace, the The first extended channel identifier and the second extended channel identifier process the first message in the second message. Through the technical solution of the application, message processing errors can be avoided, and the port isolation function can be realized.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message processing method and device. Background technique [0002] Vertical stacking is a vertical network integration virtualization technology. Through the use of this virtualization technology, the hardware resources and software processing capabilities of multiple devices can be aggregated to achieve collaborative work, unified management and uninterrupted maintenance of multiple devices. Vertical stacking can connect multiple PE (Port Extender) devices to CB (Controlling Bridge) devices, virtualize each PE device into a remote service board of the CB device, and be managed by the CB device. [0003] In a vertical stack network, ECID (Extended Channel Identifier) ​​can be used to indicate port identification, but currently only 4095 unicast ECIDs are supported, so unicast ECID can be configured for 4095 ports, that is, ECID1-ECID4095 indicates unicast ...
