PAP PAP - Password Authentication Protocol sends a username and
password over a network to a server that compares the username
and password to a table of authorized users. If the username and
password are matched in the table, server access is authorized.
CHAP CHAP is an encrypted authentication method based on Microsoft's
challenge/response authentication protocol.
DSCP/TOS Optionally mark packets with a DiffServ CodePoint (DSCP) in its
header. The DSCP value is stored in the first 6 bits of the Type of
Service (ToS) field that is part of the standard IP header. The DCSP
values are associated with a forwarding treatment called Per Hop
Behaviors (PHB). Service can be provisioned (if necessary) by
assigning a DCSP point code from 1 - 6.
