Optimization of the transmission control protocol particularly for wireless connections

A wireless network access section for providing access to a general network comprising:

• a TCP proxy for managing TCP communication therein, said proxy comprising:
• a latency aware unit for monitoring round trip time over said wireless access network section to determine latency within said wireless access section;
• and
• a filter for filtering out momentary increases in said latency that exceed a predetermined significance threshold, said filtered latency being used to generate a TCP congestion avoidance window.

A TCP-based communication network having a plurality of access network sections for providing access thereto, at least some of said access networks being wireless access networks;

• at least some of said wireless access networks having a TCP proxy for managing TCP communication therein, respective proxies comprising:
• a latency aware unit for monitoring round trip time over said wireless access network section to determine latency within said wireless access section;
• and
• a filter for filtering out momentary increases in said latency that exceed a predetermined significance threshold, said filtered latency being used to generate a TCP congestion avoidance window.

TCP Proxy method for a wireless network section comprising:

• monitoring round trip time over said wireless access network section to determine latency within said wireless access section;
• filtering out momentary increases in said latency that exceed a predetermined significance threshold;
• and
• using said filtered latency to generate a TCP congestion avoidance window.
