Frames including a packet boundary information field indicator and, optionally, packet boundary information field in addition to packet data are described. Methods and apparatus for generating and using such frames are also described. The packet boundary indicator indicates the presence or absence of at least one packet boundary information field in the frame. Frames with a payload that is fully occupied with data corresponding to a single packet do not include a packet boundary information field. The packet boundary information field indicates the location of a corresponding packet boundary and the type of boundary. One packet boundary information field is included in a frame for each boundary separating the data corresponding to different packets. By using packet boundary information fields to specify the location of packet boundaries, the need to parse an entire packet to identify the location of a packet boundary is avoided.
