Abstract

Method and corresponding device for improved bandwidth utilization featuring optimized transmission of information packets on a backhaul connection, by concatenating a few VoIP packets into a big packet with optional internal header compression. The concatenated packets are transmitted efficiently through the backhaul channel and rearranged at the receiving side. In an embodiment of the present invention, compression is applied to the concatenated packets featuring the most waste.

Claims

1. A method for operating a wireless packet-based backhaul connection comprising:

(a) establishing a backhaul connection, within an asynchronous wireless network, between a backhaul source and a backhaul destination;

(b) determining that data throughput between the backhaul source and the backhaul destination would be improved by adding the payload data of a packet received at the backhaul source to the payload of a new super-packet generated at the backhaul source for transmission to the backhaul destination, wherein determining throughput would be improved, includes factoring a likelihood of collision with other transmissions within the wireless network;

(c) generating the new super-packet including at least the data from the received packet, wherein the super-packet is adapted to include payload data from multiple separate packets received at the backhaul source;

(d) setting one or more transmission conditions for transmitting the new super-packet, wherein one or more of the transmission conditions relate to a payload capacity of the super-packet and quality of service requirements of constituent packets; and

(e) transmitting the new super-packet upon one or more of the transmission conditions being met.

2. The method of claim 1, further comprising the step of deciding whether to concatenate the received packet or transmit said received packet without concatenation.

3. The method of claim 2, wherein the performance of a user that transmitted said packet is an input parameter to the step of deciding whether to concatenate said received packet.

4. The method of claim 3, wherein measuring said performance of said user comprises identifying streaming packets and identifying the frequency at which said user should transmit its packets.

5. The method of claim 3, wherein measuring said performance of said user comprises calculating the received jitter and packet loss.

6. The method of claim 1, wherein multiple super-packets are prepared by said backhaul source in parallel.

7. The method of claim 6, wherein said received packet is added to said super-packet according to at least one of the following parameters:

traffic type, sensitivity to delay, or QoS.

8. The method of claim 1, wherein said transmission condition comprises at least one of the following:

a maximum size of said super-packet, a maximum delay for said super-packet, or a maximum number of users.

9. The method of claim 1, wherein said transmission condition comprises a maximum delay condition.

10. The method of claim 9, wherein counting said maximum delay condition starts when a new packet is received at said backhaul source.

11. The method of claim 9, wherein said maximum delay condition is calculated according to a need of a delay-sensitive application.

12. The method of claim 1, wherein said transmission condition comprises a maximum delay condition for the transmission of said super-packet and said maximum delay condition is calculated according to at least one of the following:

a network performance, a measured jitter, a measured delay, a measured packet loss, a user'"'"'s priority, a type of application running, a transmission rate, a number of retransmissions, hidden stations, or collisions.

13. The method of claim 1, wherein said transmission condition comprises a maximum delay condition for the transmission of said super-packet and said maximum delay condition is calculated according to at least one of the following:

a measured performance of a link, a transmission rate, a number of retransmissions, RSSI, or an average packet loss.

14. The method of claim 1, wherein at the received packet is transmitted by a streaming user, and said streaming user is synchronized with at least one other streaming user.

15. The method of claim 1, further comprising reordering the packets in said super-packet.

16. The method of claim 1, wherein said super-packet is compressed.

17. A network appliance for wireless backhaul networking comprising:

(a) an input for receiving a packet to be backhaul transmitted, within an asynchronous wireless network, as part of a super-packet;

(b) transmission decision logic adapted to determine that data throughput between a backhaul source and a backhaul destination would be improved by adding the payload data of a received packet to the payload of a new super-packet generated at the backhaul source for transmission to the backhaul destination, wherein determining throughput between a backhaul source and a backhaul destination would be improved, includes factoring a likelihood of collision with other transmissions within the wireless network, and further adapted to set one or more transmission conditions for transmitting the new super-packet, wherein one or more of the transmission conditions relate to a payload capacity of the super-packet and quality of service requirements of constituent packets;

(c) a packet concatenation module for generating the new super-packet including at least the data from the received packet, wherein the super-packet is adapted to include payload data from multiple separate packets received at the backhaul source; and

(d) a super-packet output adapted to transmit the new super-packet upon one or more of the transmission conditions being met.

18. The networking appliance according to claim 17, wherein said transmission decision logic comprises a counter.

19. The networking appliance according to claim 17, wherein said packet concatenation device further comprises a packet analyzer.

20. The networking appliance according to claim 17, further comprising a user synchronization device.

21. The networking appliance according to claim 17, further comprising a user type identifier.
