TCP splicing is a technique to splice two TCP connections by segment translation, so that data relaying between the two connections can be run at near router speeds. This technique can be used to speed up layer-7 switching, web proxy and application firewall running in the user space.

Introduction

TCP Splicing

Implementation

  • TCPSP - a TCP splicing implementation for the Linux operating system
  • L7SW - a high-performance framework for Layer7 switching on the Linux operating system, which uses TCP splicing engine inside the kernel.

Conclusion

TCP splicing is a technique to interconnection two separate TCP connections for fast data relay. A TCP splicer changes values in the IP and TCP headers: source and destination IP addresses, port numbers, sequence and acknowledgement numbers, and checksums.
