Credit based power management
First Claim
1. An apparatus comprising:
- circuitry capable of;
determining, at least in part, whether to issue at least one credit to at least one sender of at least one packet, the at least one credit being to grant permission, at least in part, to the at least one sender to issue a specified amount of data and also being to specify an expiration time of the permission, the at least one sender being permitted to issue to the at least one receiver only a packet data amount that the at least one receiver has specifically granted unexpired permission, as specified by the at least one credit, to the at least one sender to issue, the determining of whether to issue the at least one credit being based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the at least one credit is at least sufficient to provide at least a predetermined amount of reduction in power consumption, the relatively lower power state being relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the at least one credit.

Abstract
An embodiment may include circuitry to determine whether to issue at least one credit to at least one sender of at least one packet. The credit(s) may be to grant permission to the at least one sender to issue the at least one packet to at least one receiver of the at least one packet. The determination of whether to issue the credit(s) may be based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the credit(s) is at least sufficient to provide at least a predetermined amount of reduction in power consumption. The relatively lower power state may be relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the credit(s). Additionally or alternatively, the circuitry may be to receive such credit(s).

9. A method comprising:
determining, at least in part, by circuitry whether to issue at least one credit to at least one sender of at least one packet, the at least one credit being to grant permission, at least in part, to the at least one sender to issue a specified amount of data and also being to specify an expiration time of the permission, the at least one sender being permitted to issue to at least one receiver only a packet data amount that the at least one receiver has specifically granted unexpired permission, as specified by the at least one credit, the determining being based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the at least one credit is at least sufficient to provide at least a predetermined amount of reduction in power consumption, the relatively lower power state being relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the at least one credit. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. Non-transitory computer-readable memory storing one or more instructions that when executed by a machine result in performance of operations comprising:
determining, at least in part, whether to issue at least one credit to at least one sender of at least one packet, the at least one credit being to grant permission, at least in part, to the at least one sender to issue a specified amount of data and also being to specify an expiration time of the permission, the at least one sender being permitted to issue to at least one receiver only a packet data amount that the at least one receiver has specifically granted unexpired permission, as specified by the at least one credit, the determining being based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the at least one credit is at least sufficient to provide at least a predetermined amount of reduction in power consumption, the relatively lower power state being relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the at least one credit. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. An apparatus comprising:
circuitry to receive, at least in part, at least one credit, the at least one credit being to grant permission, at least in part, to at least one sender to issue a specified amount of data and also being to specify an expiration time of the permission, the at least one sender being permitted to issue to at least one receiver only a packet data amount that the at least one receiver has specifically granted unexpired permission, as specified by the at least one credit, determination of whether to issue the at least one credit further being based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the at least one credit is at least sufficient to provide at least a predetermined amount of reduction in power consumption, the relatively lower power state being relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the at least one credit. - View Dependent Claims (26, 27, 28, 29, 30)

31. A method comprising:
receiving, at least in part, by circuitry, at least one credit, the at least one credit being to grant permission, at least in part, to at least one sender to issue a specified amount of data and also being to specify an expiration time of the permission, the at least one sender being permitted to issue to at least one receiver only a packet data amount that the at least one receiver has specifically granted unexpired permission, as specified by the at least one credit, determining whether to issue the at least one credit further being based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the at least one credit is at least sufficient to provide at least a predetermined amount of reduction in power consumption, the relatively lower power state being relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the at least one credit. - View Dependent Claims (32, 33, 34, 35, 36)
