摘要: Methods, systems, and devices are described for stateful failover in traffic manager module functioning as a proxy between at least one first network device server. In set of embodiments, an amount synchronized state information may be reduced through controlled use acknowledgment messages. second to standby response changes sequence number delta two logically paired connections. third connections restored based on stored connection information, stack, rediscovered numbers.
