Problems solved by technology

[0007] In order to overcome the defects and deficiencies in the prior art, the present invention proposes a method and device for forwarding data packets based on the TRILL type MAC address of the Nickname of the RB, which solves the low efficiency of multicast forwarding in the prior art. At the same time, how to manage and maintain this kind of MAC address more effectively, how to integrate well with common types of MAC addresses, and how to make the MAC address table easy to manage are also explained accordingly

Embodiment Construction

[0024] In order to describe the technical content, achieved objectives and effects of the present invention in detail, the following will be described in detail in conjunction with the implementation methods and accompanying drawings.

[0025] figure 1 It is a flowchart of a data message forwarding method according to an embodiment of the present invention. Such as figure 1 As shown, the method specifically includes the following steps:

[0026] S1: The egress routing switch (RB) receives the data packet encapsulated by TRILL;

[0027] S2: The egress routing switch decapsulates the message and judges the type of the original data frame MAC address learning mechanism, if it is a hardware learning mechanism, then perform step S3; if it is a software learning mechanism, then perform step S4;

[0028] S3: According to the Nickname of the entry (Ingress) RB in the TRILL header, search the virtual port in the mapping table corresponding to the Nickname and the virtual port. After...

Abstract

The invention discloses a data message forwarding method and a forwarding device. The method and the device are applied in a multi-link transparent interconnection TRILL network and belong to the field of computer network communication. The forwarding method is correctly maintained through two MAC address learning mechanisms Based on the TRILL type MAC address of the Nickname of the RB, it is ensured that the RB can correctly learn the MAC address of the original data frame in the TRILL network, so that as many original data frames as possible can be forwarded through the known unicast TRILL forwarding table, reducing the number of traffic in the network. broadcast traffic, which improves the forwarding performance of the TRILL network. At the same time, this method can realize the unified management of ordinary MAC addresses and TRILL type MAC addresses and can replace between ordinary MAC addresses and TRILL type MAC addresses.

Description

technical field [0001] The invention relates to the field of computer network communication, in particular to a forwarding method and a forwarding device of a data message, and the method and the device are applied in a multi-link transparent interconnection TRILL network. Background technique [0002] In a Transparent Interconnection of Lots of Link (TRILL for short) network, a switch running the TRILL protocol has both Layer 2 forwarding and Layer 3 routing functions, and is usually called a Router Bridge (RB for short). [0003] In the TRILL network, the RB runs the intermediate system to intermediate system (Intermediate system to intermediate system, IS-IS) protocol to diffuse the state of the link connected to it in its area, so as to transmit the topology information maintained by itself. RB has enough information to calculate the optimal path of unicast to any network node, and can calculate the multicast distribution tree for unicast, multicast or broadcast of unkno...
