Abstract
Abstract The present invention is directed to a packet-centric wireless point to multi-point telecommunications system, including: a wireless base station coupled to a first data network; one or more host workstations coupled to the first data network; one or more subscriber customer premise equipment (CPE) stations in wireless communication with the wireless base station over a shared bandwidth using a packet-centric protocol; and one or more subscriber workstations coupled to each of the subscriber CPE stations over a second network; a resource allocation device optimizing end-user quality of service (QoS) and allocating shared bandwidth among the subscriber CPE stations; a device for analyzing and scheduling an internet protocol (IP) flow over the shared wireless bandwidth. The analyzing device includes a characterizing device for characterizing the IP flow. The characterizing device can include a device for determining whether a packet is older than a threshold age. The age determining device can include a device for analyzing a time to live (TTL) packet header field for determining the age of the packet, or a device for anticipating application IP flow discards based on the age of the packet. The characterizing device can include a device for determining a QoS requirement for the IP flow if the IP flow is a new IP flow. The characterizing device scan include a device for determining a subscriber CPE identification for a subscriber CPE station associated with the IP flow if the IP flow is a new IP flow.
