25-2 IP Policy Routing

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 12 policy sets with six

policies in each set.

Menu 25 shows all the policies defined.
