A likely architecture for the future broadband access network will consist of a trunk-and-branch topology, with very high bandwidth trunks (e.g., 1-10 Gb/s), connected to high-bandwidth drops (or branches) to homes and businesses. A multihop switched

Asynchronous transfer mode (ATM) networks carry fixed-size cells within the network irrespective of the applications being supported. At the network edge or at the end equipment, an ATM adaptation layer (AAL) maps the services offered by the ATM netw

Many popular point-to-point data link protocols use the high-level data link control (HDLC) framing mechanism, which delineates protocol data units (PDUs) by means of a special bit pattern or flag. When such a flag occurs in the payload portion of a

Traditional Internet protocol (IP) networks are built with very limited-capacity planning and design optimization, and can only provide best-effort service without performance guarantees. To meet customer expectations, however, IP networks must be de

The simple data link (SDL) is a new framing protocol for variable/fixed length packets over a general-purpose point-to-point communications channel. SDL extends the HEC-like framing mechanism used in ATM to variable-length data. Its low implementatio
