UDP/IP Header Compression
Short question: Is there a way to enable UDP/IP header compression in Linux?
Background: I'm using pppd which supports Van Jacobson header compression (RFC 1144) but this applies to TCP and excludes UDP. The RFCs I've seen mentioned are:
RFC 1144 "Compressing TCP/IP Headers for Low-Speed Serial Links"
RFC 2507 "IP Header Compression"
RFC 2508 "Compressing IP/UDP/RTP Headers for Low-Speed Serial Links"
RFC 3095 "RObust Header Compression (ROHC): Framework and four profiles: RTP, UDP, ESP, and uncompressed"
RFC 3241 "Robust Header Compression (ROHC) over PPP"
RFC 4995 "The RObust Header Compression (ROHC) Framework"
RFC 5225 "RObust Header Compression Version 2 (ROHCv2): Profiles for RTP,
UDP, IP, ESP and UDP-Lite[/I]"
Are any of these algorithms implemented in the Linux kernel and, if so, how do I enable them?
