Abstract

The disclosure generally relates to methods, system and apparatus to optimize Quality of Service (QoS) for communications using Medium Agnostic Universal Serial Bus (MA USB) protocol. In one embodiment, assignment of specific QoS parameters for certain Endpoint is triggered by the platform running MA USB host once a specific usage model occurs. Once triggered, MA USB Host engages an MA USB Hub or Device in a two-way handshake to communicate QoS parameters. The two-way handshake includes transmitting an Update Endpoint Quality-of-Service (QoS) Request frame to the selected Endpoint Handles at the MA USB Device; and receiving an Update Endpoint QoS Response from the MA USB Device.

First claim

What is claimed is:

1 . A method to communicate one or more Quality-of-Service (QoS) parameters between a Medium Agnostic Universal Serial Bus (MA USB) Host and an MA USB device having one or more Endpoints, the method comprising:
determining one or more parameters to be communicated to an identified Endpoint; executing a two-way handshake with the MA USB device to communicate the one or more QoS Parameters, wherein the two-way handshake further comprises:
transmitting an Update Endpoint Quality-of-Service (QoS) Request frame to the first Endpoint at the MA USB Device; and
receiving an Update Endpoint QoS Response from the MA USB Device.

2 . The method of claim 1 , wherein the Update Endpoint QoS Request further comprises a data frame having one or more of transfer type, Endpoint Handle list, Priority and QoS parameters.

3 . The method of claim 2 , wherein the QoS parameters quantifies the end-to-end QoS parameters that the packets belonging to the identified Endpoint encounters.

4 . The method of claim 1 , further comprising, dynamically updating the prioritization parameter by sending a subsequent Update Endpoint Quality-of-Service (QoS) Request frame to the first Endpoint at the MA USB Device.

5 . The method of claim 1 , wherein the device further comprises an MA USB Hub or a MA USB portable device configurable to execute the two-way handshake.

6 . The method of claim 1 , wherein the Update Endpoint Quality-of-Service (QoS) Request frame comprises a payload identifying: transfer type, priority level, negative priority, Endpoint Channel Delay, Requested Bandwidth, Bandwidth Averaging Window and EP Handle List.

7 . A Medium Agnostic Universal Serial Bus (MA USB) Host comprising a Physical Adaptation Layer (PAL) and a Media-Access Control (MAC) Layer to provide prioritized data transmission to a one of plurality of Endpoints within in an MA USB device, wherein the HUB includes processing logic executable on a the PAL or the MAC layer to:
determine one or more QoS parameters to be communicated to an identified Endpoint; execute a two-way handshake with the MA USB device to communicate the one or more QoS Parameters, wherein the two-way handshake further comprises:
transmitting an Update Endpoint Quality-of-Service (QoS) Request frame to the first Endpoint at the MA USB Device; and
receiving an Update Endpoint QoS Response from the MA USB Device.

8 . The MA USB Host of claim 7 , wherein the Update Endpoint QoS Request further comprises a data frame having one or more of transfer type, Endpoint Handle list, Priority and QoS parameters.

9 . The MA USB Host of claim 8 , wherein the QoS parameters quantifies the end-to-end QoS parameters that the packets belonging to the identified Endpoint encounters.

10 . The MA USB Host of claim 7 , wherein the processing logic further comprises dynamically updating the prioritization parameter by sending a subsequent Update Endpoint Quality-of-Service (QoS) Request frame to the first Endpoint at the MA USB Device.

11 . The MA USB Host of claim 7 , wherein the Update Endpoint QoS Response is received from an MA USB Hub or a MA USB portable device configured to execute the two-way handshake.

12 . The MA USB Host of claim 7 , wherein the Update Endpoint Quality-of-Service (QoS) Request frame comprises a payload identifying: transfer type, priority level, negative priority, Endpoint Channel Delay, Requested Bandwidth, Bandwidth Averaging Window and EP Handle List.

13 . A Medium Agnostic Universal Serial Bus (MA USB) Hub comprising a Physical Adaptation Layer (PAL) and a Media-Access Control (MAC) Layer to receive data transmission to one of plurality of Endpoints associated therewith, wherein the Hub includes processing logic executable on the PAL or the MAC layer to:
receive an Update Endpoint Quality-of-Service (QoS) Request frame from an MA USB Host, wherein the Update Endpoint Quality-of-Service (QoS) Request frame is directed to an identified Endpoint associated with the MA USB Hub; and transmit an Update Endpoint QoS Response to the MA USB Hub.

14 . The MA USB Hub of claim 13 , wherein the processing logic includes verifying the Update Endpoint Quality-of-Service (QoS) Request frame before transmitting an Update Endpoint QoS Response to the MA USB Hub.

15 . The MA USB Hub of claim 13 , wherein the Update Endpoint QoS Request further comprises a data frame having one or more of transfer type, Endpoint Handle list, Priority and QoS parameters.

16 . The MA USB Hub of claim 15 , wherein the QoS parameters quantifies the end-to-end QoS parameters that the packets belonging to the identified Endpoint encounters.

17 . The MA USB Hub of claim 13 , wherein the processing logic further comprises dynamically updating the prioritization parameter when a subsequent Update Endpoint Quality-of-Service (QoS) Request frame is received.

18 . The MA USB Hub of claim 13 , wherein the Update Endpoint QoS Request is received from an MA USB Host.
