USER’S GUIDE
330 CyberSWITCH
to operate, albeit without compression. An error message will be logged indicating an internal
decompression failure.
Compression is negotiated independently on inbound and outbound channels. It is possible to
provide compression in one direction while not in the opposite direction.
Should the peer not support PPP compression, CCP will fail to converge and the link will continue
to operate without providing compression. Should the peer support CCP, but not the Stac protocol,
the CCP negotiation will succeed, but no actual compression will occur on the connection.
Note: The CyberSWITCH does not support individual link compression when PPP Multilink is
negotiated to aggregate multiple links. Multiple links to a single destination will be treated
as a single high capacity link as far as PPP compression is concerned. One history will be
kept for the group of links, and packets will be compressed before they are fragmented for
transmission across the multiple links.
The following documents provide additional information about PPP Compression:
• The PPP Compression Control Protocol (CCP); RFC 1962; Dave Rand; June, 1996.
• PPP Stac LZS Compression Protocol; RFC 1974; Robert Friend and William Allen Simpson; Au-
gust 1996.
