Dispatching method, dispatching apparatus and dispatching system

A dispatching apparatus, comprising:

• a central processing unit (CPU) coupled to a memory;
• a receiving unit, configured to receive a request initiated by a user terminal, wherein the request carries address information of the user terminal;
• an obtaining unit, configured to obtain the address information carried in the request and obtaining key information of an access server associated with the address information;
• a dispatching handling unit, configured to search for a corresponding node based on the key information of the access server obtained by the obtaining unit, wherein the node serves as a redirected serving node;
• wherein the obtaining unit comprises:
• a first processing unit, configured to record bonding relationship between the address information of the user terminal and the key information of the access server, wherein the bonding relationship is synchronized by a management system;
• a second processing unit, configured to obtain, after the address information is obtained from the receiving unit, the key information of the access server associated with the address information carried in the request, based on the bonding relationship between the address information of the user terminal and the key information of the access server, wherein the bonding relationship is synchronized by the management system;
• and
• a third processing unit, configured to request, if the second processing unit fails to obtain the key information of the access server associated with the address information carried in the request, the key information of the access server associated with the address information from the management system, and receive from the management system the key information of the access server associated with the address information.

A dispatching system, comprising:

• an access server, configured to receive a request initiated by a user terminal and forward the request, wherein the request carries address information of the user terminal;
• and
• a dispatching apparatus, configured to receive the request forwarded by the access server, obtain the address information carried in the request and obtain key information of the access server associated with the address information, and search for a corresponding node based on the key information of the access server, wherein the node serves as a redirected serving node;
• wherein the dispatching apparatus comprises:
• a central processing unit (CPU) coupled to a memory;
• a receiving unit, configured to receive the request forwarded by the access server;
• an obtaining unit, configured to obtain, after the address information carried in the request is obtained, the key information of the access server associated with the address information in the request, based on recorded bonding relationship between the address information of the user terminal and the key information of the access server, wherein the bonding relationship is synchronized by a management system and configured to request the key information of the access server associated with the address information from the management system, and receiving from the management system the key information of the access server associated with the address information, if the obtaining of the key information of the access server associated with the address information carried in the request fails;
• and
• a dispatching handling unit, configured to search for a corresponding node based on the key information of the access server obtained by the obtaining unit, wherein the node serves as a redirected serving node.
