Abstract
A method and system is provided for a scalable clustered system. The method and system may handle asynchronous traffic as well as session backup. In the method and system, a home cluster member having ownership of a local session predicts designation of a an other cluster member to receive a packet associated with the local session and sends appropriate state information or forwarding instruction to the other network member.
Claims25
A method of synchronizing a clustered system having at least a first member and a second member, the method comprising:
- a) relaying from the first member to the second member information associated with a packet before arrival of said packet to the second member, and
- b) predicting designation of the second member to receive said packet.
A computer-readable storage media comprising computer-executable instructions stored thereon, the computer-executable instructions, when executed, configuring a clustered system to perform actions comprising:
- a) relaying of information associated with a packet from a first member of the clustered system to a second member of the clustered system before arrival of said packet to said second member, and
- b) predicting designation of said second member to receive said packet.
A clustered system including a plurality of members, comprising:
- a) a memory accessible to a first member of the plurality of members, said memory configured to store
- i) a state machine and
- ii) an algorithm for predicting designation of a second member of the plurality of members to receive a packet, and
- b) a processor accessible to said first member, said processor configured to execute said algorithm.
