This algorithm implements
header compression, usually over low speed (300 to 19,200 bps) serial links, which can reduce packet header overhead from 4000% to 300%, enough to yield acceptable interactive performance at 2400 bps. This is often used in conjunction with
PPP (
CPPP).
Van Jacobson compression provides an end-to-end checksum. The original TCP checksum is always preserved, transmitted unmodified, and used to check the validity of the reconstructed packet.
