Spectrum efficiency is a primary goal. RFC2508 does not perform well enough. The relative overhead is the average header overhead relative to the payload. Error propagation due to header compression should be kept at an absolute minimum. Error propagation is defined as the loss or damage of headers subsequent to headers lost or damaged by the link, even if those subsequent headers are not lost or damaged.
Error propagation reduces spectral efficiency and reduces quality.
CRTP suffers severely from error propagation. Handover operations can be frequent in cellular systems. Failure to handle handover well can adversely impact spectrum efficiency and quality. ROHC must not introduce erroneous headers during such events, and should not introduce packet loss during such events. Must operate under all expected link delay conditions.
