Description

Processing method, device and system of expansion port

technical field

The present invention relates to the field of communications, and in particular, to a method, device and system for processing an expansion port.

Background technique

With the popularity of the cloud computing concept, data center network technology has ushered in a drastic change. A large number of new technology standards have emerged in recent years, and various equipment manufacturers have also invested massive resources to meet this new challenge. With the development of cloud computing, virtual machines have proliferated, and enterprise data centers have inevitably caused management problems. The network must adapt to the new trend of virtualization technology. Therefore, the network side has made some new 802.1 standards for new technology trends and demand adjustments such as virtual machine migration in the data center. The 802.1BR standard is a standard specified by IEEE for local and metropolitan networks. The purpose is to break the physical limitations, expand the bridge and bridge management objects through 802LAN technology and interactive interfaces, and transfer a large number of policies and security and management methods from the network card. The virtual machines and blade servers on the server are removed, and they are handed over to the physical Ethernet switches that connect storage and computing resources, simplifying the management of data center systems. With the new Ethernet standard, data centers can support converged networks using data center bridging, priority-based flow control, and increased congestion control.

The 802.1BR standard establishes an extension bridge system, including a control device (Controlling Bridge, referred to as CB) and one or more extension devices (Port Extender, referred to as PE). The CB configures and monitors the PE through the PE Client Server Protocol (Client Server Protocol, CSP for short). The PE reports the existing extended port to the CB through the Extended Port Create message (Extended Port Create) defined by the PE CSP. After the CB receives the message, it creates a corresponding virtual port so that the user can connect the port of the physical bridge through the point-to-point local area network (Local Area Network). Area Network, abbreviated as LAN) connection is extended to remote PE. The PE reports the port status (MAC_Operational) of the extension port to the CB through the Port Status Parameters Set message. After the CB receives the message, it feeds back the MAC_Operational status of the extension port to the corresponding virtual port through the link status (MAC_Enabled) parameter. .

The CB cannot directly learn the state of the PE when the corresponding virtual port is created initially. At present, the method adopted by most equipment manufacturers is that after the PE is started, only the extended port whose MAC_Operational status is TRUE is notified to the CB device through the Extended Port Create message, and the CB directly sends the corresponding virtual port after receiving the message. The port's MAC_Enabled is set to TRUE. The disadvantage of this method is that the extended port whose MAC_Operational state is off (FALSE) cannot be quickly discovered and monitored. In addition, if the extended port state changes from TRUE to FALSE, the extended port in the FALSE state may or may not have a corresponding virtual interface. Case.

Aiming at the problem in the related art that the control device CB cannot quickly discover and monitor the status information of the expansion port of the expansion device PE, no effective solution has been proposed yet.
