Problems solved by technology

[0015] In the prior art, the forwarding of unicast packets in the TRILL network is only limited to the local area. When the TRILL network is deployed on the DCI (Data Center Connection) to implement the core network of the Layer 2 network, the two DCI networks TRILL networks are independent of each other, and communication between TRILL networks in different places cannot be realized

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] see Figure 5 , Figure 5 It is a schematic diagram of a TRILL network communication network across an IP network provided by an embodiment of the present invention. Such as Figure 5 As shown, DC1 and DC2 are two data center interconnection (DCI) networks in different places. They are connected through an IP network. TRILL networks are deployed in both DC1 and DC2. Among them, the RBridges on the core layer of the TRILL network in DC1 such as S1 and S2 As the DCI device of DC1 (denoted as the first DCI device), it is connected to the RBridge on the TRILL network access layer in DC1, such as S10, S11, ... S20, etc., and the RBridge on the TRILL network access layer in DC1 RBridge is recorded as the first access layer device; RBridges on ...

Abstract

The invention provides a crossed IP network TRILL (transparent interconnection of lots of links) network communication method, a system thereof and devices. The method is characterized in that: a DC1 and a DC2 are two remote DCI (data center connection) networks which are connected through an IP network, both the DC1 and the DC2 are provided with TRILL networks, a first DCI device is an RBridge on a TRILL network core layer in the DC1, a first access layer device is any RBridge on a TRILL network access layer in the DC1, a second DCI device is an RBridge on the TRILL network core layer in the DC2, and a second access layer device is an RBridge device on the TRILL network access layer in the DC2. The method comprises the following steps: the first DCI device learns route generation Nickname forwarding tables of an RBridge in a local TRILL network and an RBridge in a remote TRILL network, and after receiving a TRILL message sent to the DC2 or receiving a TRILL message from the DC2, the first DCI device forwards the TRILL message according to the Nickname forwarding tables.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a method, system and device for transparent interconnection of lots of links across IP networks (TRILL: Transparent Interconnection of Lots of Links). Background technique [0002] TRILL is a Layer 2 network technology formulated by the Internet Engineering Task Force (IETF: Internet Engineering Task Force), and the technical framework has been basically determined. TRILL is mainly used in data center networks to solve the following problems in Spanning Tree Protocol (STP) networks: insufficient links, possible non-optimal paths for data flow forwarding, and temporary loops. [0003] All devices in the TRILL network support the TRILL function, which has a switch function and a routing function, and is called a routing bridge (RBridge). Each RBridge in the TRILL network has a unique Nickname, which is 16 bits in size and is automatically assigned by the protocol. see ...
