Abstract

Techniques for managing heterogeneous traffic streams are described. An apparatus may include wireless device having a transceiver and a media access control controller operative to communicate in a wireless network, the media access control controller having a traffic stream manager operative to establish a wireless communication channel between a first and second wireless device, and communicate multiple traffic streams in a single service period over the wireless communication channel, with each traffic stream having a different level of reliability for delivery of information from the first wireless device to the second wireless device. Other embodiments are described and claimed.
