Abstract

The invention discloses an Ethernet communication method and system and an SDN exchanger. The method comprises the steps that the SDN exchanger reports the MAC address learned locally to an integrated controller, and the integrated controller issues forwarding tables of forwarding ports corresponding to target MAC addresses to all SDN exchangers under a management domain based on whole network topology automatic finding and route computing based on strategies; and the SDN exchangers achieve Ethernet frame forwarding according to the MAC address forwarding tables learned locally and the MAC address forwarding tables issued by the integrated controller. The integrated controller issues the MAC address forwarding tables to the SCN exchangers in the management domain, the boundedness that a traditional Ethernet exchanger learns whole network MAC addresses through a data forwarding plane is avoided, and the problems that broadcast storm and spanning tree protocols exist in the traditional Ethernet, so that a large amount of redundancy chain blocking is caused, network convergence speed is slow, and traffic engineering cannot be achieved are solved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, system and SDN switch for Ethernet communication. Background technique [0002] Traditional Ethernet has problems such as broadcast storms, massive redundant link congestion caused by STP (Spanning Tree Protocol), slow network convergence, and inability to implement traffic engineering. These problems limit the network scale of Ethernet, and cannot adapt to the emerging cloud computing, big data and other business applications and innovations. [0003] figure 1 A typical networking architecture of a data center network constructed by using traditional Ethernet switches is shown. In order to avoid broadcast storms caused by loops, the switch must enable STP to block some ports, resulting in low utilization of network links and a non-optimal path for Ethernet traffic, as shown in the figure. If the link between the incoming switches is blocked, it needs to be bypasse...
