Method and apparatus for the efficient use of available communications network bandwidth
View Patent ↗A communications network gateway receives a stream of information formatted to be compatible with a first sub-network and it receives a stream of information formatted to be compatible with a second sub-network. The frames in the second stream are extracted and modified to be compatible with the transmission format of the first sub-network. The two streams of information are then aggregated for transmission over a logical network link in a manner that optimizes the bandwidth utilization of the overall communications network.
1. A method for optimizing network bandwidth utilization, comprising:
receiving at a network gateway a stream of information formatted for transmission over a first sub-network of the network and receiving a stream of information only formatted for transmission over a second sub-network of the network;
terminating the stream of information formatted for transmission over the first sub-network to form a stream of terminated frames and terminating the stream of information formatted for transmission over the second sub-network by extracting only header and payload information from the formatted information to form a stream of extracted frames;
modifying the stream of extracted frames by adding a condensed IP header to each of the extracted frames to create an IP packet and encapsulating the IP packet in a point-to-point protocol multiplex format to form a point-to-point protocol frame;
statistically aggregating the stream of terminated frames with the modified stream of extracted frames to form a statistically aggregated stream of frames; and
transmitting the statistically aggregated stream of frames over the logical link from the first network gateway to a second network gateway in a manner that optimizes the use of the available bandwidth in the network.
2. The method of claim 1 further comprising selecting at least one higher priority frame over a lower priority frame for aggregation and transmission over the logical link from the first network gateway to a second network gateway.
3. The method of claim 1 wherein the network is a backhaul network that supports CDMA based traffic.
4. The method of claim 1 wherein the formatted information included in the first stream is terminated at layer two as defined by the OSI reference model.
5. The method of claim 1 wherein the formatted information in the second stream is terminated by extracting the header and the payload from the formatted information to form an extracted frame.
6. The method of claim 1 wherein the first backhaul sub-network is designed to support communications traffic based on at least one of EVDO, LTE and WiMax technologies.
7. The method of claim 1 wherein the second backhaul sub-network is designed to support communications traffic based on the 1xRTT technology.
8. The method of claim 1 wherein the stream of terminated frames and the stream of modified, extracted frames are aggregated according to the priority of each point-to-point protocol multiplex frame.
9. The method of claim 1 wherein the logical link is comprised of the first and second sub-networks.
10. The method of claim 1 wherein the second network gateway receives the statistically aggregated stream of frames over the logical link, terminates a point-to-point multiplex frame format and restores the original formatting to each frame according to whether it is to be transmitted over the first sub-network or over the second sub-network of the network.
