PPP Multiline

Nortel Networks PPP services include support for the multiline feature, which lets

you configure a single circuit that consists of one or more WAN data paths. A data

path is a logical point-to-point channel that is a permanent (leased) line. Multiline

provides both increased fault tolerance and greater bandwidth between two sites.

See the section “Differences Between Multiline and Multilink

” on page 2-17 for a

comparison of these features. For more information about the Nortel Networks

multiline feature, see Configuring WAN Line Services or Configuring Ethernet,

FDDI, and Token Ring Services.

PPP Multilink

The multilink feature of PPP provides capabilities beyond those of multiline

circuits. The major characteristics of multilink include the ability to

• Use lines that have different speeds, proportionally distributing traffic over

those lines

• Balance traffic load and maintain packet sequence

• Use switched lines (such as ISDN-B channels) as well as leased lines

• Monitor traffic volume

Configurations with bandwidth-on-demand, which can activate additional lines in

response to increased traffic, can find these features particularly useful.
