This charter is a snapshot of the 47th IETF Meeting in Adelaide, Australia. In addition, existing schemes do not compress TCP options such as SACK or Timestamps. The goal of ROHC is to develop header compression schemes that perform well over links with high error rates and long roundtrip times. However, the schemes should also be applicable to other future link technologies with high loss and long roundtrip times. Ideally, it should be possible to compress over unidirectional links.
Good performance includes both minimal loss propagation and minimal added delay.
ROHC may develop multiple compression schemes, for example, some that are particularly suited to specific link layer technologies. Schemes in addition to those listed in the milestones below may be added in consultation with the area directors. The working group shall maintain connections with other standardization organizations developing cellular technology for IP, such as 3GPP and 3GPP-2, to ensure that its output fulfills their requirements and will be put to good use. In addition, the WG should develop a solid understanding of the impact that specific error patterns have on the compression schemes, and document guidelines to Layer 2 designers regarding what Layer 2 features work best to assist Layer 3 and Layer 4 header compression. Current Meeting Report None received.
