Abstract
In accordance with one embodiment, a method includes creating a first session object by a first traffic processor of a first network element operating in an active mode, the first session object being associated with a communication session between an end user terminal and an information provider. The method further includes sending a state synchronization message associated with the first session object from the first traffic processor. The state synchronization message includes a transport layer address associated with a second traffic processor of a second network element operating in a standby mode. The state synchronization message is adapted to be received by the second traffic processor and cause the second traffic processor to create a second session object, the second session object tracking the communication session between the end user terminal and the information provider.
