Abstract

A packet-centric wireless system includes: a wireless base station communicating via a transmission control protocol/internet protocol (TCP/IP) to a first data network; one or more host workstations communicating via TCP/IP to the first data network; one or more subscriber customer premise equipment (CPE) stations coupled with the wireless base station over a shared bandwidth via TCP/IP over a wireless medium; and one or more subscriber workstations coupled via TCP/IP to each of the subscriber CPE stations over a second network. The system can allocate shared bandwidth among the subscriber CPE stations to optimize end-user quality of service (QoS). The first data network includes at least one of: a wireline network; a wireless network; a local area network (LAN); and a wide area network (WAN). The second network includes at least one of: a wireline network; a wireless network; a local area network (LAN); and a wide area network (WAN).

Claims

1. A method comprising:

a wireless communication device detecting toss of a transmission control protocol (TCP) packet on a wireless network; and

the wireless communication device retransmitting the TCP packet within the wireless network without invoking TCP retransmission responsive to detecting the toss.

2. The method of claim 1, further comprising:

managing a TCP transmission widow for packets over the wireless network by transmitting a packet receipt acknowledgement before a TCP sender detects a lost packet and initiates retransmission.

3. The method of claim 2 wherein managing the TCP transmission window further occurs before the TCP sender resets transmission rates for packets.

4. The method of claim 1 wherein the retransmitting is performed at a media access control (MAC) layer of a protocol stack.

5. A method comprising:

a wireless communication device detecting toss of a transmission control protocol (TCP) packet on a wireless network at a media access control (MAC) layer of a protocol stack in the wireless communication device; and

responsive to detecting the loss, the wireless communication device retransmitting the TCP packet within the wireless network from the MAC layer prior to a TCP layer detecting a loss of the TCP packet.

6. The method as recited in claim 5 further comprising:

transmitting a packet receipt acknowledgement from the MAC layer to a TCP sender to prevent the TCP sender from detecting a lost packet and initiating retransmission and resetting transmission rates for packets.

7. A computer readable storage medium configured to store a plurality of instructions which, when executed on a device that is configured to communicate over a wireless network:

detect loss of a transmission control protocol (TCP) packet on the wireless network at a media access control (MAC) layer of a protocol stack; and

retransmit the TCP packet within the wireless network from the MAC layer without invoking TCP retransmission responsive to detecting the loss.

8. The computer readable storage medium of claim 7 the plurality of instructions, when executed:

manage a TCP transmission widow for packets over the wireless network by transmitting a packet receipt acknowledgement before a TCP sender detects a lost packet and initiates retransmission.

9. The computer readable storage medium of claim 8 wherein the TCP sender is coupled to the device separate from the wireless network.

10. The computer readable storage medium of claim 9 wherein the TCP sender is a customer subscriber unit.

11. The computer readable storage medium of claim 8 wherein the TCP sender is coupled to the device via a wired connection.

12. The computer readable storage medium of claim 8 wherein the packet receipt acknowledgement is transmitted before the TCP sender resets transmission rates for packets.
