no. 1 Embodiment

[0142] The first specific embodiment, such as Figure 7 As shown in the figure, take the interworking between VM2 in the subnet under NVE1 whose outer tunnel IP address is 1.1.1.1 and VM7 in the subnet under NVE3 whose outer tunnel IP address is 3.3.3.3 as an example. The specific process of Layer 2 network interworking between devices in the subnet below is as follows:

[0143] Step 701: VM2 sends a message carrying the IP address and MAC address of VM7 to the directly associated NVE1.

[0144] Step 702: NVE1 looks up the local ARP table, adds NVO3 encapsulation to the received message according to the ARP information of VM7 stored in the ARP table and the outer layer tunnel IP address of NVE3 directly associated with VM7, and sends it to the three-layer network ( L3Network), the Layer 3 network sends the packet to NVE3 according to the external destination IP address carried in the encapsulated packet.

[0145] In the encapsulated packet, the inner source IP (Inner SIP) is...

no. 7 Embodiment

[0174] In the seventh specific embodiment, the specific process for the external device to communicate with the gateway NVE of the subnet is as follows: the external device with the IP address of 172.16.1.100 sends a request message whose destination IP address is the VIP (G-VIP) of the distributed gateway. The text is forwarded to NVE2 by selecting the shortest path according to the routing weight; NVE2 returns a response message to the external device.

[0175] In the above first to seventh specific embodiments, the distributed gateway is deployed in the same area. In practical applications, the distributed gateway also supports cross-area deployment without any special processing.

[0176] Based on the above technical solution, in the embodiment of the present invention, by setting each NVE of the distributed gateway to have the same VIP and VMAC, each NVE establishes an intercommunication tunnel through the outer tunnel IP address, effectively reducing the implementation co...

Abstract

The invention discloses a distributed gateway, a message processing method and a message processing device based on the distributed gateway, which aim at improving the flexibility and expandability of network deployment, realizing load sharing and traffic optimization, and improving efficiency. The distributed gateway comprises a plurality of network virtualization endpoints (NVE). Each NVE has the same virtual internet protocol (VIP) address and the same virtual media access control (VMAC) address. Each NVE establishes interconnecting tunnels with other NVEs through the IP address of an outer layer tunnel. Each NVE is configured with a routing protocol for releasing a network segment route of a corresponding subnet.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a distributed gateway, a message processing method and device based on the distributed gateway. Background technique [0002] With the development of cloud computing technology, public cloud and hybrid cloud data centers for large-scale tenants have become the focus of network construction. At the same time, this new network service model puts forward new requirements for network construction. For example, in order to be able to provide public cloud and hybrid cloud data center services, it is necessary to build an application-centric infrastructure architecture, a fully automated and programmable network infrastructure, and a common open platform that can support physical, virtual, and cloud infrastructure Wait. [0003] A distributed gateway is a network connector based on a distributed system. It has the advantages of decentralized functions, decentralized r...
