Embodiment Construction

[0051] exist figure 1In the network structure shown, all servers have the same IP address as a logical node externally, so as to provide a unified access address for nodes on the Internet. For business messages from the Internet that initiate access to logical nodes with the same destination address , the service sharing device distributes these service packets to different servers in the logical node, and a single server responds. This distribution is the distribution of connections, that is, the access services with the same destination address are distributed to the connections with different servers, The connection information is in the upper layer of the IP layer in the message, and the connection-based exchange is carried out through the four-layer to seven-layer information of the message.

[0052] How to make the same IP address applicable to different network nodes is a problem that needs to be solved to realize service sharing by switching below the three layers. Tho...

Abstract

The network apparatus comprises a client side port group and two serving side port groups for bearing the service from said client side port group. The method comprises: the serving side port groups are separately allocated to the two serving VLAN, which are not in connection each other; letting the address information of client in service message correspond to a certain VLAN; the service message is forwarded by the serving VLAN corresponding to the address information of client. The invention implements the service allocation based on information of layer 2 and 3.

Description

technical field [0001] The present invention relates to switching technology in the field of network and data communication, in particular to a method for realizing service sharing in switching equipment and switching equipment applying the method. Background technique [0002] Most applications implemented over the network require servers to undertake key processing tasks. With the growth of business, the processing capacity of the server will become the bottleneck of performance. Since it can take into account both scalability and reliability, the server cluster with business sharing function becomes the first choice to solve this problem. [0003] figure 1 Shown is a typical network structure applied by a network device with a service sharing function. Servers 121, 122, 123, and 124 form a server cluster, and are connected to the Internet through the service sharing device 110 to respond to service access from the Internet. Servers The cluster composed of 121, 122, 123,...
