CQ NOTE

After you configure the packet compression or header compression, the configuration takes effect only

after the restart command, or the shutdown and the undo shutdown commands are used. If you apply

the compression to MP, you must use the restart command, or the shutdown and the undo shutdown

commands on all the interfaces bound by MP.

Van Jacobson TCP Header Compression (VJ TCP) is an algorithm of compression. The

algorithm compresses the header of TCP/IP into 3 bytes to enhance the e^iciency of the
low-speed line.

For the details of VJTCP, refer to RFC1144.
