Protocol Prioritization

When you configure a router, you can prioritize the different types of traffic sent

across a line. This process is called protocol prioritization. When you configure

leased bandwidth circuits, the router automatically enables protocol prioritization.

Prioritizing traffic is important for your time-sensitive applications.

For example, a user at router A participating in a Telnet session with router B

requires a more immediate response than a user at router A performing a file

transfer with router B.

Although protocol prioritization is set automatically, you still need to configure

priorities and filters. For more information about protocol prioritization, see

Configuring Traffic Filters and Protocol Prioritization.

Defining the Role of the Router in the Network

Leased bandwidth circuits are point-to-point connections. For each circuit, you

must designate a router at one end of the connection as the congestion monitor.

The congestion monitor checks the congestion of the lines in a multilink bundle. If

this router discovers congestion, it activates secondary lines. The router at the

other end of the connection, the non-monitor router, does not have the authority to

activate a secondary line. Do not set the Bandwidth Mode parameter to the same

value for both routers. This will prevent the routers from activating a second line

simultaneously.

You define the role of the router using the Bandwidth Mode parameter, which is

part of the bandwidth circuit configuration (see “Customizing

Bandwidth-on-Demand Service” on page 14-2).

Balancing Traffic Between Lines in a Multilink Bundle

With multilink enabled for bandwidth-on-demand service, the router divides the

outbound data traffic among all links in the bundle. The external clock speed of

each line determines how much of the total traffic each link receives. On the

receiving end, multilink resequences packets arriving on different links using the

sequence number from the multilink header.

For more information about traffic distribution, see Configuring PPP Services.
