Multi-Link PPP Configuration

Multi-link PPP (MLPPP) is a standard (RFC 1990 and RFC 1717) for inverse multiplexing, a method of combining individually dialed channels into a single, higher speed data stream. MLPPP is an extension of PPP that supports the ordering of data packets across multiple channels. Although MLPPP can be implemented on any WAN device, it was the rapid emergence of ISDN BRI as a cost efficient higher bandwidth alternative to modems which has driven the evolution and acceptance of MLPPP. Typically MLPPP is used to combine the speed of two ISDN BRI B- Channels to get 128Kbps of virtual capacity.

Before implementing MLPPP on the DI-308, please ensure that your ISP or the device to which you are connecting supports, and is configured for MLPPP.

MLPPP can be implemented in two ways, dynamically through the use of the Bandwidth on Demand (BOD), and statically. BOD causes the second ISDN port to place a call and add bandwidth to the ISDN connection when the BOD High Threshold is exceeded for the Add Bandwidth Delay period. Bandwidth can also be subtracted when ISDN throughput falls below the BOD Low Threshold and Subtract Bandwidth Delay parameters. Thus, BOD economizes MLPPP by maintaining only the bandwidth needed.

A static implementation of MLPPP is achieved when BOD is disabled but the ISDN ports have Multi-Link enabled. In this case, when the two ISDN ports have established a connection, the router will check to see if they are connected to the same source and whether the source supports MLPPP. If both conditions are met, the router will automatically bundle the two links together as an MLPPP connection.

Items in the Multi-Link PPP Configuration window are described as follows:
