Abstract
A way of managing bandwidth in a network supporting variable bit rate is provided. An apparatus is provided that comprises an interface to transmit data to a receiving device. The apparatus comprises a controller that is communicatively coupled to the interface, the controller to detect a bit rate change event and transmit a first portion of the data using reserved bandwidth and a second portion of the data using unreserved bandwidth in response to detecting the bit rate change event.
Claims25
An apparatus, comprising:
- a wireless communications device containing an interface and a controller communicatively coupled to the interface, the device to:
- request and receive a first reserved bandwidth for transferring data based on a pre-selected bit rate;
- detect a bit rate change event and in response to detecting said event to transmit a first portion of the data using the first reserved bandwidth and a second portion of the data using unreserved bandwidth;
- and
- request a second reserved bandwidth for transferring the data.
An article comprising one or more machine-readable storage media containing instructions that when executed by at least one processor enable a wireless communications device to:
- request and receive a first bandwidth reservation;
- transfer data using the first bandwidth reservation;
- detect a reduced transfer rate;
- transmit a first portion of the data using the first bandwidth reservation and a second portion of the data using unreserved bandwidth in response to detecting the reduced transfer rate;
- and
- request a second bandwidth reservation in response to detecting the reduced transfer rate.
A method performed by a wireless communications device, the method comprising:
- requesting and receiving a first bandwidth reservation for transferring data at a pre-selected bit rate;
- transmitting a first portion of the data over the first bandwidth reservation and a second portion of the data over unreserved bandwidth in response to determining that a current bit rate is less than the pre-selected bit rate;
- and
- requesting a second bandwidth reservation for transferring the data.
A system, comprising:
- a client device to communicate with a wireless network hub in a wireless network, wherein the client device is to:
- transmit data using a prior bandwidth agreement with the wireless network hub;
- detect a bit rate change event and transmit a first portion of the data under the prior bandwidth agreement and a second portion of the data not under any bandwidth agreement in response to detecting the bit rate change event;
- and
- request a new bandwidth agreement with the wireless network hub in response to said detecting the bit rate change event.
