Abstract
A system and method for adjusting a level of compression for endpoint devices. Endpoint devices in a network can stream audio/video traffic over a network. Such a connection between the endpoint devices can be reserved with guarantees of latency being obtained. Latency guarantees across multiple intermediary switches can be used to define a compression level for the end devices.
Claims16
A network communication method, comprising:
- prior to a transport of an audio/video stream, reserving a connection with a guaranteed level of latency for said transport between a first endpoint device and a second endpoint device, said reservation being performed across one or more bridge devices between said first and second endpoint devices;
- prior to an initiation of said transport, choosing a compression level having an associated latency level that can be accommodated by said reserved level of latency of said connection;
- compressing said audio/video stream at said chosen level of compression;
- and
- transmitting said compressed audio/video stream from said first endpoint device to said second endpoint device.
2 more elements
A network device, comprising:
- a controller that identifies a level of latency that has been reserved for a connection between the network device and an endpoint device, said level of latency being reserved across one or more switches between the network device and said endpoint device;
- and
- a compression module designed to compress traffic for transmission over said connection, said compression module being responsive to said controller in choosing a compression level based on said level of latency that has been reserved across said one or more switches.
A network communication method, comprising:
- requesting a reservation for a connection that traverses one or more bridge devices between a first and a second endpoint device, said request including an identified level of latency, wherein said request is based on a first level of compression;
- and
- if said request is denied, compressing said audio/video stream at a second level of compression different from said first level of compression.
