ENHANCEMENTS FOR TCP PERFORMANCE ENHANCING PROXIES

摘要

Methods and systems are described that may be used in the context of a Performance Enhancing Proxy architecture for Internet traffic. A method of accelerated connection opening with error handling is disclosed. Also, a method of handling the Path MTU Discovery mechanism in the context of a distributed connection splitting PEP is described. A novel packet format for a proprietary inter-PEP protocol is described which allows for low packet header overhead. A new acknowledgement scheme that adapts to packet loss conditions to minimize bandwidth consumption by selecting an acknowledgement type from several possibilities is also detailed. A method whereby potentially spurious retransmissions are minimized by timing every transmission and retransmission is also described.
