Embodiment 1

[0096] image 3 It is an implementation flowchart of a message conversion method provided by the present invention, the method is applied to the node device side, such as image 3 As shown, the method mainly includes the following steps:

[0097] Step 301: When forwarding packets from the UNI physical port to the NNI physical port, use different actions for different packets according to the first type of flow table issued by the server side, so as to realize packet encapsulation.

[0098] Preferably, said using different action operations for different messages according to the first type of flow table issued by the server side, so as to realize message encapsulation, may include:

[0099] According to each flow table in the first type of flow table, Ethernet header encapsulation, PW label encapsulation, and LSP label encapsulation are sequentially performed for packets from UNI to NNI.

[0100] Preferably, the first type of flow table includes: a first flow table, a second...

Embodiment 2

[0137] Such as figure 2 As shown, when the UNI (client side) message enters the device from node A for transmission, the message needs to be encapsulated from UNI to NNI. At this time, the server or upper-layer controller needs to generate a corresponding flow table (the first type of flow table) Send it to the A-side device. Figure 4 A schematic diagram of message conversion from UNI to NNI provided by the present invention, such as Figure 4As shown, the flow table processing flow is as follows: the data frame is from the UNI physical port to the NNI physical port, the client frame enters from the UNI physical port, and flows in the direction of the NNI physical port.

[0138] For the first type of flow table, it consists of two parts, one part is the matching operation, and the other part is the action operation. The first type of flow table includes: a first flow table, a second flow table, a third flow table, a fourth flow table, and a fifth flow table.

[0139] Firs...

Embodiment 3

[0172] Such as figure 2 As shown, when the NNI (network side) message is transmitted by the Z-node outgoing device, the message needs to be encapsulated from NNI to UNI. At this time, the upper-layer controller needs to generate a corresponding flow table (the second type of flow table) and send it to the Z-end device. Figure 5 The schematic diagram of the message conversion of NNI to UNI provided for the present invention, as Figure 5 As shown, the data frame is from the NNI physical port to the UNI physical port, and the flow table processing flow is as follows: the data frame is from the UNI physical port to the NNI physical port, and the network frame enters from the NNI physical port and flows in the direction of the UNI physical port.

[0173] For the second type of flow table, it consists of two parts, one part is the matching operation, and the other part is the action operation. The second type of flow table includes: the sixth flow table, segment laminar flow ta...

Abstract

The invention discloses a message conversion method. The message conversion method comprises steps that when messages are forwarded from a user network interface (UNI) physical port to a network-to-network interface (NNI) physical port, different messages are operated by different motions according to a first-class flow table issued by a server side, and a message packaging is realized; when the messages are forwarded from the NNI physical port to the UNI physical port, the different messages are operated by different matching rules and the different motions according to a second-class flow table issued by the server side, and then the unpacking of the messages is realized. The invention also discloses a message conversion device and a message conversion system at the same time. By adopting the technical scheme provided by the invention, the problem of the prior art of inability of directly using a standard OpenFlow protocol for packet message forwarding is solved.

Description

technical field [0001] The present invention relates to the field of Software Defined Network (SDN, Soft Defined Network), in particular to a message conversion method, device and system. Background technique [0002] With the explosive growth of network traffic, the pressure on the operation and maintenance of the existing network is increasing. It is the general trend to use the advanced network system architecture to optimize the structure of the existing network. SDN is a new type of network innovation architecture and a way to realize network virtualization. Its core technology, OpenFlow, separates the control layer and forwarding layer of network forwarding equipment, thereby realizing flexible control of network traffic, providing a core network and application Innovation provides a platform. [0003] In the existing network, Packet Transport Network (PTN, Packet Transport Network) equipment has been widely used, but it mainly relies on static configuration routing f...
