MLPPP

Overview

MLPPP provides a way to distribute data across multiple links within an MLPPP APS bundle to achieve high bandwidth. MLPPP allows for a single frame to be fragmented and transmitted across multiple links. This reduces latency and allows for a higher maximum received recovery unit, or MRU.

MLPPP is supported in MC APS groups. See MC APS for more information about MC APS.

Multiclass MLPPP

Multiclass MLPPP is an extension of the MLPPP standard which allows multiple classes of service to be transmitted over an MLPPP bundle.

Multiclass MLPPP changes the MLPPP header to include either two or four class bits to allow for up to either four or 16 classes of service. This allows multiple classes of services over a single MLPPP connection. The highest priority traffic is transmitted over the MLPPP bundle with minimal delay, regardless of the order in which packets are received.

Multiclass MLPPP is useful in mobile network deployments where multiple types of traffic, each with its own priority level, travel across a single MLPPP link bundle between the base station router and the aggregation router in the point of presence (POP) mobile operator.

Note: Multiclass MLPPP allows for several classes of services to be transmitted over an MLPPP bundle. Link fragmentation and interleaving, however, allows for only two classes of service to be transmitted. Multiclass MLPPP and link fragmentation and interleaving are mutually exclusive.
