PPP Plus

MLPPP-the multilink point-to-point protocol-delivers some key functions to help network managers build multiprotocol enterprise networks. Here are some of MLPPP's strongest selling points:

- Mix-and-match WANs With MLPPP, net managers can configure multiple physical links and virtual circuits as one logical pipe, using different WAN service types (ISDN, frame relay, X.25, and ATM) in the process.

- Bandwidth on demand Circuits can be activated and added automatically to a logical pipe when more bandwidth is needed or if one of the links in the logical pipe fails.

- Big protocol tent Like the point-to-point protocol (PPP) that preceded it, MLPPP handles routing for all major network- and transport-layer protocols, including IP, IPX, Netbios, DECnet, and SNA.

- Network negotiation MLPPP also has inherited PPP's ability to negotia te configuration options between communicating devices. This means two end systems can set the terms of transmission without requiring manual intervention.

- No traffic, no link MLPPP uses LAN protocol spoofing to keep unnecessary network traffic, such as session keep-alive packets, from traversing the WAN.
