[Abstract]:With the rapid development of network technology, data center has gradually become the key facility of most enterprises in the data-centric network world. In order to realize the reliability of network service, many enterprises distribute data centers in many different geographical locations. In order to enhance the mobility of resources and the flexibility of management, the data center must provide the second layer network connection between the different data centers without compromising the stability of the whole network. Traditionally, layer 2 forwarding can only be done in LAN based on MAC address, so an important aspect of extending layer 2 domain is to realize the notification of MAC address between different sites. In this paper, the standard ISIS protocol is modified according to the requirement of two-layer extension between data centers, and a MAC address notification scheme between data centers is proposed based on ISIS protocol. In this paper, the MAC address notification scheme between different data centers is implemented on the software development platform of a company. The software adopts multithread mechanism, including system event processing, neighbor maintenance LSP maintenance, route maintenance four thread modules. The system event processing is responsible for the preparation and scheduling of the system, the neighbor maintenance thread is responsible for the neighbor relationship of the site and the local MAC address information maintenance thread is responsible for the generation of the LSP message. Synchronization and MAC information extraction from LSP; routing maintenance thread is responsible for remote MAC address information processing and brushing. Finally, the software function is tested on the actual equipment. The test results show that the MAC address information of the local equipment is notified to the remote equipment, and the MAC address information forwarding table of the local equipment is established, which meets the expected MAC address notification requirement.
