Problems solved by technology

[0005] Currently, full connections are established between EDs of all site networks in the overall EVI network. figure 1 In the vlink, even all sites of the same service must establish a full connection for intercommunication. In this way, as the number of sites increases, the connections in the EVI network increase in series, which is not conducive to management and service control

Embodiment Construction

[0031] 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.

[0032] In the present invention, in order to facilitate network management and service control, data centers in the EVI networking are hierarchically distinguished, wherein the hierarchical distinction is mainly based on the purpose of facilitating network management. Such as figure 2 As shown, in the EVI networking application, there are the following three data centers: the provincial data center, the city A data center, and the city B data center. Based on this, the present invention can differentiate these three data centers hierarchically, such as , the provincial data center is the first level, and the city A data center and the city B data center are both lower levels of the first level, for example, both are the second level, or the city ...

Abstract

The invention provides a business access method and an edge device. In the business access method and the edge device, virtual retransmission channels are built between different electron devices (ED) in a same data center. Virtual retransmission channels are only built between EDs working as ENDS in an upper level and EDs working as ENDS in a lower level among EDs in different data centers. The fact that virtual retransmission channels are built between EDs in all data centers in the prior art is not needed, so that network management and business control are convenient.

Description

technical field [0001] This application relates to network communication technology, in particular to a service access method and edge equipment. Background technique [0002] Ethernet Virtualization Interconnection (EVI: Ethernet Virtualization Interconnection) technology is based on existing service provider networks and enterprise networks, and provides flexible Layer 2 interconnection functions for dispersed sites. The EVI solution is very simple and low-cost. It only needs to deploy one or more EVI-enabled devices, referred to as edge devices (ED: Edge Device), at the edge of the site, and the enterprise network and service provider network do not need to make any changes. [0003] EVI is an advanced MAC in IP technology used to implement L2VPN technology based on IP core network. EVI only maintains routing and forwarding information on the ED of the site without changing the internal and core networks of the site. The overall network of EVI is composed of Core networ...
