| 摘要 |
The invention provides, in one aspect, a server load balancer (SLB) recovery method that replicates a primary SLB 's connection data after the primary SLB experiences a failure, as opposed to before it experiences a failure as is currently done in the known hot stand-by recovery method. In some embodiments, this is made possible by (1) employing a replication agent on each target processing unit (e.g., each processing unit on which a server application runs) and (2) transmitting, from the primary SLB, connection data information (i.e., information comprising a session identifier) to the replication agent running on the target processing unit to which the session is mapped, which replication agent will store the data until it is required to transmit the data to a cold stand-by SLB. |
