Abstract

Embodiments of the present invention comprise systems and methods for network connection setup and bandwidth allocation comprising negotiable and non-negotiable modulation allocation procedures.

Claims

1. A method for establishing a network connection, said method comprising:

a. receiving a request for a network connection;

b. receiving an indication of said connection'"'"'s sensitivity to connection negotiation delay;

c. assigning a negotiable modulation allocation when said sensitivity to network connection delay is not significant; and

d. assigning a fixed modulation allocation when said sensitivity to network connection delay is significant.

2. A method as described in claim 1 wherein said indication of said connection'"'"'s sensitivity to connection negotiation delay is a QoS parameter.

3. A method as described in claim 1 wherein said indication of said connection'"'"'s sensitivity to connection negotiation delay is determined by the type of device requesting said network connection.

4. A method for establishing a network connection, said method comprising:

a. initiating a request for a network connection;

b. sending an indication of said connection'"'"'s sensitivity to connection negotiation delay;

c. receiving a negotiable modulation allocation when said sensitivity to network connection delay is not significant; and

d. receiving a fixed modulation allocation when said sensitivity to network connection delay is significant.

5. A method as described in claim 4 wherein said indication of said connection'"'"'s sensitivity to connection negotiation delay is a QoS parameter.

6. A method as described in claim 4 wherein said indication of said connection'"'"'s sensitivity to connection negotiation delay is determined by the type of device requesting said network connection.

7. A method for establishing a network connection, said method comprising:

a. receiving a request for a network connection,

b. granting a negotiable modulation allocation when said connection will not be adversely impacted by connection modulation negotiation; and

c. granting a fixed modulation allocation when said connection will be adversely impacted by connection modulation negotiation.

8. A method as described in claim 7 further comprising establishing a channel analysis period.

9. A method as described in claim 7 further comprising receiving a configured bandwidth report.

10. A method for establishing a network connection, said method comprising:

a. initiating a request for a network connection,

b. receiving a negotiable modulation allocation when said connection will not be adversely impacted by connection modulation negotiation; and

c. receiving a fixed modulation allocation when said connection will be adversely impacted by connection modulation negotiation.

11. A method as described in claim 10 further comprising sending a configured bandwidth report.

12. A method as described in claim 10 further comprising negotiating connection modulation parameters.

13. A method as described in claim 10 further comprising sending and measuring a known pattern between network devices.

14. A method as described in claim 10 further comprising sending modulation parameters between network devices.

15. An apparatus for establishing a network connection, said apparatus comprising:

a. a receiver for receiving a request for a network connection; and

b. a connection manager for granting connection allocations, wherein a negotiable modulation allocation is granted when said connection will not be adversely impacted by connection modulation negotiation; and

c. wherein a fixed modulation allocation is granted when said connection will be adversely impacted by connection modulation negotiation.

16. An apparatus for establishing a network connection, said apparatus comprising:

a. a requester for requesting a network connection,

b. an indicator for indicating a sensitivity to connection delay;

c. a negotiator for negotiating connection modulation parameters when said sensitivity to connection delay is low.
