Embodiment 1

[0049] The message forwarding method in the SPBM network according to Embodiment 1 of the present application can be performed by any BEB device. Such as image 3 As shown, the method includes the following parts:

[0050] 1. Learning of the MAC address in the remote user network

[0051] In the embodiment of the present application, for the learning of the MAC address in the remote user network, the self-learning method of the prior art is no longer used, that is, after decapsulating the received M-in-M message to obtain the unicast Ethernet If the source MAC address in the unicast Ethernet message is unknown, it is not allowed to learn the source MAC address. Instead, the MAC address notification and synchronization method is used, that is, the same service instance is set The BEB devices notify each other and synchronize the MAC address of the service instance learned from the local user network, so as to achieve the purpose of learning the MAC address in the remote user ...

Embodiment 2

[0105] Regarding the method in the first embodiment above, the embodiment of the present application provides a message forwarding device to which the method can be applied, and the device is applied to a BEB device.

[0106] Such as Figure 5 As shown, the following modules are included in the device: receiving module 10, determining module 20, searching module 30 and sending module 40, wherein:

[0107] A receiving module 10, configured to receive a unicast Ethernet message from a local user network;

[0108] Determining module 20, for determining the first service instance corresponding to the VLANID and the ingress port of the unicast Ethernet message after the receiving module 10 receives the unicast Ethernet message;

[0109] The search module 30 is used to search for a matching entry in the MAC address table corresponding to the first local service instance according to the destination MAC address of the unicast Ethernet message received by the receiving module 10;

...

Abstract

The present application discloses a message forwarding method and device in an SPBM network. The SPBM network includes: a plurality of BEB devices and user networks connected thereto. The method is applied to BEB devices. The method includes: receiving a message from a local user After receiving the unicast Ethernet packet from the network, determine the VLAN associated with the unicast Ethernet packet? ID and the first service instance corresponding to the incoming port; according to the destination MAC address of the unicast Ethernet packet, search for a matching entry in the MAC address table corresponding to the first local service instance; if no matching entry is found , the unicast Ethernet packet is only broadcast to the port connected to the local user network in the first service instance. The application effectively suppresses the flooding of unicast Ethernet packets with unknown destination MAC addresses to the backbone network, saving the network bandwidth of the backbone network.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to a message forwarding method and device in an SPBM network. Background technique [0002] SPB (ShortestPathBridging, the shortest path bridge) is an Ethernet standard defined by IEEE802.1aq, which is a further extension of MSTP (Multiple Spanning Tree Protocol, Multiple Spanning Tree Protocol), aiming to build a large flat non-blocking Layer 2 network. SPB uses SPBIS-IS (IntermediateSystemtoIntermediateSystem, intermediate system to intermediate system) to share the link state in the network, and each node in the network calculates the shortest path between each node in parallel, avoiding the use of STP (SpanningTreeProtocol, Spanning Tree Protocol) The instability caused by the protocol and the low utilization efficiency of some links. [0003] IEEE802.1aq defines two SPB modes: VLAN mode (SPBV (ShortestPathBridgingVLANMode, shortest path bridge in VLAN m...
