Abstract

See full text

Systems and methods for data traffic management in a node in a data network. A data path element receives data packets from the network and receives instructions from a buffer management element, coupled to the data path element, whether specific data packets are to be accepted for buffering or not. This decision is based on the status of a buffer memory bank coupled to the data path element. If a data packet is accepted, a data unit descriptor for that packet is queued for processing by a scheduler element coupled to the data path element. The scheduler element determines when a specific data packet is to be dispatched from the buffer memory bank based on the queued data unit descriptor.
