摘要： Message formats and apparatus are described that reserve access to a communication medium in a multicast system. A first message, a multicast request-to-send message, includes a duration field having information representing the reserved time for a communication medium, multicast receiver and transmitter address fields, and bits that specifies a destination that is expected to reply to the multicast digital message. The bits that specify a destination can be extended to a plurality of fields that each contain different destination identifiers. Example destination identifiers include association identifiers or media access control addresses. Alternately, the bits that specify a destination can have a first field containing an offset and a second field indicating destinations with respect to the offset. A second message includes a duration field and multicast receiver and transmitter address fields. The second message is used to cancel a data transmission resulting from a multicast request-to-send message.
