AA TCP Optimization (TCPO) allows operators to leverage their existing access network deployments to provide higher throughput and improve users’ experience. AA TCPO overcomes the inherited inefficiencies of TCP when faced with larger round-trip delays, high bandwidth, and non-congestion related packet loss, which are common in wireless access networks.
In particular, TCP connections have several factors that affect the effective throughput and users’ experience:
Round Trip Time (RTT) delay and available bandwidth
TCP window size
TCP reaction to error in both the slow start and congestion avoidance that result in random TCP packet loss not because of congestion (for example, because of interference on the access side)
buffer bloating in the mobile access network
