links where peer-to-peer (P2P) traffic is accepted;

a medium time of the P2P traffic; and

a bandwidth of the links where the P2P traffic is accepted.

3 . The device of claim 1 ,

wherein negotiation of the SCS for the multiple links includes:

requesting traffic characteristics via a QoS Characteristics element of an SCS Request frame; and

receiving an SCS Response frame, wherein the SCS Response frame indicates that the requested traffic characteristics were accepted.

4 . The device of claim 3 ,

wherein the SCS Response frame indicates accepted traffic characteristics via a QoS Characteristics element of the SCS Response frame.

5 . The device of claim 4 ,

wherein the QoS Characteristics element of the SCS Response frame indicates at least one of a link bitmap of P2P traffic for a requested link and an updated service interval.

6 . The device of claim 1 ,

8 . The device of claim 1 ,

wherein a link bitmap included in at least one of a QoS Characteristics element and an SCS Descriptor element that is transmitted during the SCS negotiation indicates links being used for negotiated traffic.

9 . The device of claim 1 ,

wherein the device negotiates restricted Target Wake Time (rTWT) parameters in an rTWT negotiation according to the negotiated SCS.

10 . The device of claim 9 ,

wherein a Target Wake Time (TWT) element transmitted in the rTWT negotiation includes an SCS identifier (ID) (SCSID) that indicates a traffic stream whose frames are serviced in an rTWT service period (SP).

11 . The device of claim 9 ,

wherein a TWT element transmitted in the rTWT negotiation includes an SCS Descriptor element that indicates a traffic stream whose frames are serviced in an rTWT SP.

12 . The device of claim 1 ,

wherein a Service Start Time is defined by a timing synchronization function (TSF) time of a link where an SCS Request frame is transmitted during the SCS negotiation.

13 . The device of claim 1 ,

wherein a Service Start Time is defined by a link from the multiple links of the negotiated SCS with at least one of a smallest TSF time and a largest TSF time.

14 . The device of claim 1 ,

wherein a Service Start Time is defined by a TSF time of a link from the multiple links of the negotiated SCS with at least one of a smallest Link ID and a largest Link ID.

15 . The device of claim 1 ,

wherein the device exchanges the frames in a traffic stream, and

wherein a TWT of the traffic stream and a Service Start Time of the traffic stream are the same.

16 . The device of claim 1 ,

wherein the device exchanges the frames in a traffic stream, and

wherein a TWT of the traffic stream is before a Service Start Time of the traffic stream.

17 . The device of claim 1 ,

wherein the device exchanges the frames in a traffic stream, and

wherein a TWT of the traffic stream is after a Service Start Time of the traffic stream.

18 . A device comprising:

a wireless network interface device implemented on one or more integrated circuits (ICs),

wherein the wireless network interface device is configured to:

negotiate a Stream Classification Service (SCS) for multiple links; and

exchange frames on the multiple links according to the negotiated SCS;

wherein negotiation of the SCS for the multiple links includes:

requesting traffic characteristics via a QoS Characteristics element of an SCS Request frame; and

receiving an SCS Response frame, wherein the SCS Response frame indicates that the requested traffic characteristics were accepted;

wherein the SCS Response frame indicates accepted traffic characteristics via a QoS Characteristics element of the SCS Response frame; and

wherein the QoS Characteristics element of the SCS Response frame indicates at least one of a link bitmap of P2P traffic for a requested link and an updated service interval.
