37-2 IP Policy Routing
address and port, ToS and precedence (fields in the IP header) and length. The inclusion of length criterion
is to differentiate between interactive and bulk traffic. Interactive applications, e.g., telnet, tend to have
short packets, while bulk traffic, e.g., file transfer, tends to have large packets.
The actions that can be taken include:
• Routing the packet to a different gateway (and hence the outgoing interface).
• Setting the ToS and precedence fields in the IP header.
IPPR follows the existing packet filtering facility of RAS in style and in implementation. The policies are
divided into sets, where related policies are grouped together. A user defines the policies before applying
them to an interface or a remote node, in the same fashion as the filters. There are 4 policy sets with six
policies in each set.
