Embodiment Construction

[0018] The ED device in the EVI network can encapsulate the Layer 2 packet in the user network as a payload into an IP packet, so that when the IP packet reaches another physical site through the IP network, the Layer 2 packet can be obtained from the IP packet. packets, so as to realize logical Layer 2 intercommunication. In fact, users may plan many Layer 2 networks in their own networks. These Layer 2 networks are distinguished by VLANs. Different VLANs cannot communicate with each other at Layer 2, but they can achieve Layer 3 intercommunication within the user network. In order to achieve three-layer interworking, EVI technology can also support users to use ED as a gateway for user access devices, including the existing single gateway mode and multi-gateway mode.

[0019] Please refer to figure 1 As shown, when the ED is used as a gateway device, the IP forwarding between different physical sites is realized through the ED gateway. The host Host11 in site 1 belongs to ...

Abstract

The invention provides a user message processing method and device, and the user message processing method and device are applied to EDs in an EVI network. The method includes the steps of setting up class-II EVI channels facing towards a public router and at least one EVI VPN channel facing towards a VPN router in an assigned EVI embodiment, inquiring a VPN to which a user router protocol message belongs, if the corresponding VPN is inquired, conducting routing learning on the VPN, if not, conducting routing learning in a public domain, inquiring a VPN to which a user data message belongs when IP forwarding is conducted on the user data message, if the corresponding VPN is inquired, forwarding the user data message according to a VPN router forwarding list, and if not, forwarding the user data message according to a public router forwarding list. According to the method and device, a user is allowed to conduct more flexible programming in a private network of the user, and the user can set up different IP networks to meet the requirements of the user.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a user message processing method and device. Background technique [0002] To achieve high reliability and enable redundant deployments, most enterprise networks and their data centers today span multiple physical sites located in different geographical locations. Enterprises may deploy similar business services at these sites. For example, if the same user visited Weibo yesterday in Guangdong and today in Heilongjiang, the service experience they get is the same, but in fact the servers serving the user may be distributed in different locations. [0003] The emergence of virtualization technology allows virtual machines in the data center to be migrated on different physical servers. However, since the virtual machine migration process needs to be transparent to users, the IP address cannot be changed, which requires that the migration must be limited to the L...
