Problems solved by technology

[0011] It can be seen that the above code lengths lead to excessive information load during protocol interaction, which increases network bandwidth consumption; moreover, there are usually a lot of VIDs that need to be transmitted, which causes the code length to often exceed the maximum message length required by the VDP protocol

Embodiment Construction

[0049] Specifically, three methods (technical solutions A, B, and C) can be provided to compress the virtual local area network identification (VID) code in the filtered information, reduce the code length of the filtered information part, and reduce the size of the information load during protocol interaction. Network bandwidth consumption; and it can effectively avoid the problem that the encoding length exceeds the maximum information length of 512 bytes required by the VDP protocol due to too many VIDs to be transmitted.

[0050] Technical solution A

[0051] From image 3 It can be seen that the VID code in the filtering information is 2 bytes, but in fact, the effective vlanid ranges from 1 to 4094, and only 12 bits are needed to express it. For example, the code change of the filtering information format is VID as follows: image 3 . In addition, the VID changes in the three filtering information encodings are as follows: image 3 , are changed from 2 bytes to 12 bits,...

Abstract

The invention discloses a method and system for realizing continuous vlan compressed transmission, which can maintain the continuous VID encoding format including continuous VID identification, start VID and end VID; when there are multiple continuous VIDs, the continuous VID is applied encoding format to encode. The method and system of the present invention can effectively compress continuous vlans during the transmission of vlan information in the VDP protocol, significantly reduce the information flow during protocol interaction, and at the same time avoid the excessive length of the protocol message as much as possible.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for realizing continuous virtual local area network (vlan) compressed transmission. Background technique [0002] With the maturity of server virtualization technology, more and more virtualized server data are deployed in data centers. The emergence of a virtual machine (VM) makes a VEB (Virtual Ethernet Bridge, Virtual Ethernet Bridge) appear in the data center server network access layer. The VEB realized by pure software on the server is the so-called vSwitch (virtual switch). vSwitch is currently a mature technical solution with good productization. [0003] While server virtualization in the data center can greatly improve resource utilization and flexibility, it also introduces new management and design challenges, often misunderstood as the network perimeter (or network access layer), where there are The switch provides network communication. In the virtua...
