Application access method in a plurality of application service platform systems

The invention discloses an application access method in a plurality of application service platform systems. The application access method comprises the following steps: in one application service platform system, a proxy server receives a client-side request message, determines a corresponding application, creates an application context, adds the application context to the client-side request message and then distributes the client-side request message to an application server in which the corresponding application is located; after receiving the client-side request message sent by the proxy server, the application server delivers the client-side request message to the corresponding application for processing the message; the corresponding application processes the client-side request message and performs data resource location according to the application context so as to obtain the processing result; the application server returns the processing result to a client side through the proxy server; and a gateway performs cross-system access to the application among the application service platform systems. By adopting the application access method, the development difficulty of the application platform systems can be reduced, the deployment flexibility can be improved, and the deployment difficulty can be lowered.

Virtual network access method and system

The invention discloses a virtual network (VN) access method and system. The method comprises the following steps: BN-NVE accepts access of VN in a data center by a wide-band subscriber terminal and generates a forwarding table of the VN and corresponding table items; the BN-NVE is in forwarding table information interaction with the NVE (Network Virtualization Edge) of the accessed VN to form the information synchronization of the VN forwarding table; looking up the VN forwarding table by the BN-NVE according to the destination address of the massage of the wide-band subscriber terminal, transmitting the message to a destination NVE in the VN after the massage is encapsulated through a tunnel, and then transmitting the message to a destination VM through the destination NVE, so that the NV access of the wide-band subscriber terminal is completed. Another method comprises the following steps: a VN business development and management entity in the data center accepts an access request of the wide-band subscriber terminal on the VN in the data center and selects one NVE of the VN as the accessed NVE of the VN; a security tunnel is established between the accessed NVE of the VN and the wide-band subscriber terminal, and the VN access of the wide-band subscriber terminal is completed through the security tunnel. The method solves the problem that the gateway of the data center becomes a bottleneck because an internet user accesses the VN in the data center.
