Apparatus, system and method of controlling data flow over a communication network

摘要

Some demonstrative embodiments include apparatuses, systems and/or methods of controlling data flow over a communication network. For example, an apparatus may include a communication unit to control the transfer of a stream of data from a first device to a second device over a communication link, the stream of data including data to be delivered to a plurality of endpoints. For example, the controlling may include communicating between the first and second devices at least one message including at least one endpoint-specific credit consumption unit (CCU) defined with respect to at least one endpoint of the plurality of endpoints.

主权项

1. An apparatus comprising a memory and a processor, the processor configured to cause a Universal Serial Bus (USB) Protocol Adaptation Layer (PAL) host of a media-agnostic connectivity PAL to:
transmit to a USB PAL device an endpoint handle request to assign one or more handles to one or more endpoints of a USB device, the endpoint handle request comprising one or more endpoint descriptors corresponding to the one or more endpoints; process an endpoint handle response from the USB PAL device, the endpoint handle response comprising the one or more handles of the one or more endpoints, and one or more credit consumption units (CCUs) corresponding to the one or more endpoints; and track an available buffer space of the USB PAL device for an endpoint based on a CCU of said one of more CCUs corresponding to the endpoint.
