Embodiment Construction

[0039] There are so many ways to implement the present invention that it is difficult to describe them all here. Some presently possible preferred embodiments are described below. However, it cannot be overemphasized that these are descriptions of embodiments of the invention rather than the invention, and that the invention is not limited to the embodiments described here, but is described in a broader scope in the claims.

[0040] As shown in Figure 1, a network architecture 2 includes a communication medium 3 and a network 4 through which electronic devices 6, 8 and 10, such as audiovisual devices, communicate. The electronic devices 6, 8 and 10 include media access controllers (MACs) 12, 14 and 16, which manage access to the network 4 for the electronic devices 6, 8 and 10, respectively. MACs 12, 14 and 16 implement the data link layer and connect to the physical layer (PHY) of the Open Systems Interconnection (OSI) network architecture standard. In general, MACs 12, 14 ...

Abstract

A method of operating in a network in which a plurality of stations communicate over a shared medium, comprising providing a physical layer (e.g., PHY) for handling physical communication over the shared medium; providing a high level layer (e.g., PAL) that receives data from the station and supplies high level data units (e.g., MSDUs) for transmission over the medium; providing a MAC layer that receives the high level data units from the high level layer and supplies low level data units (e.g., MPDUs) to the physical layer; at the MAC layer, encapsulating content from a plurality of the high level data units; dividing the encapsulated content into a plurality of pieces (e.g., segments) with each piece capable of being independently retransmitted; and supplying low level data units containing one or more of the plurality of pieces.

Description

technical field [0001] The present invention relates to network protocols, and more particularly to a media access control layer that encapsulates data from multiple received data units. Background technique [0002] Networking protocols are typically developed in layers, with each layer responsible for a different aspect of communication. Structured information is exchanged between layers. Each layer receives service data units (SDUs) from higher layers, processes these SDUs to produce protocol data units (PDUs). Protocol data units are passed to lower layers for servicing. Similarly, PDUs received from lower layers are processed to generate SDUs, which are delivered to higher layers. The PDU carries not only the SDU, but also management information about the management layer functionality. It is critical to define the structure of SDUs and PDUs for a specific protocol layer so that the proper layer functionality is available. Some examples of network protocol layers i...
