Method and system for reestablishing connection information on a switch connected to plural servers in a computer network
First Claim
1. A method for reestablishing connection information on a switch connected to plural servers in a computer network, comprising:
- identifying, at the switch, information to be transferred through the switch between a client and a first server;
determining an absence of connection information on the switch used to transfer the information between the client and the first server through the switch;
transferring the information to a victim server using a dispersal algorithm that is established at the switch through one of the plural servers, the victim server being one of the plural servers designated to handle the transfer upon determining an absence of connection information on the switch; and
responding to the determining by reconstructing the connection information on the switch using connection information extracted from an information packet passing through the switch from at least one of the plural servers during a communication associated with the information.

Abstract
A method and system are disclosed for reestablishing connection information on a switch connected to plural servers in a computer network. In accordance with exemplary embodiments of the present invention, an identification is made, at the switch, of information to be transferred through the switch between a client and a first server. A determination is made of an absence of connection information on the switch for transferring the information from the client to the first server through the switch. In response to determining an absence of connection information, the connection information on the switch is reconstructed using connection information extracted from an information packet passing through the switch from at least one of the plural servers during a connection associated with the information.

14. A system for reestablishing connection information in a switch of a computer network, comprising:
-
plural servers; a switch, connected to each of the plurality of servers, for identifying information transferred through the switch between a client and a first server, for determining an absence of connection information on the switch used to transfer the information from the client to the first server through the switch, and for responding to the determination of the absence of connection information by reconstructing the connection information on the switch using connection information extracted from an information packet passing through the switch from at least one of the plurality of servers during a communication associated with the information, wherein said switch is configured to transfer the information to a victim server using a dispersal algorithm that is established at the switch through one of the plurality of servers, the victim server being one of the plural servers designated to handle the transfer upon determining an absence of connection information on the switch. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method for reestablishing connection information on a switch connected to plural servers in a computer network, comprising:
-
identifying, at the switch, information to be transferred through the switch between a client and a first server; determining an absence of connection information on the switch used to transfer the information between the client and the first server through the switch; and responding to the determining by reconstructing the connection information on the switch using connection information extracted from an information packet passing through the switch from at least one of the plural servers during a communication associated with the information, wherein at least one of the plural servers notifies the switch of a dispersal algorithm to be used by the switch for allocating computer network connection address space of the plural servers and, upon determining an absence of connection information on the switch, the information is transferred to a victim server using the dispersal algorithm.

24. A system for reestablishing connection information in a switch of a computer network, comprising:
-
plural servers; a switch, connected to each of the plurality of servers, for identifying information transferred through the switch between a client and a first server, for determining an absence of connection information on the switch used to transfer the information from the client to the first server through the switch, and for responding information from the client to the first server through the switch, and for responding to the determination of the absence of connection information by reconstructing the connection information on the switch using connection information extracted from an information packet passing through the switch from at least one of the plurality of servers during a communication associated with the information, wherein at least one of the plural servers notifies the switch of a dispersal algorithm to be used by the switch for allocating computer network connection address space of the plurality of servers and, upon determining an absence of connection information on the switch, the information is transferred to a victim server using the dispersal algorithm.
