Abstract
The present disclosure is directed to a multi-level resource reservation system that obviates one or more of the problems due to limitations and disadvantages of the related art. The multi-level resource reservation system creates, or modifies existing, peer-to-peer protocol(s) to complete a continuous chain of configured ports to support QoS feature(s), e.g., bound latency and guaranteed jitter, for a data flow that traverses an arbitrary sequence of bridges, routers, and virtual links.
Claims20
A method of multiple level resource reservation for a data stream in a peer-to-peer protocol, comprising:
- making a resource reservation request at a first layer;
- and
- subsequently requesting resource reservation request at a second layer, wherein the second layer is higher than the first layer;
- wherein, if the resource reservation request at the first layer fails, then failing the resource reservation at the second layer;
- wherein if the resource reservation request at the second layer fails, then withdrawing the resource reservation at the first layer.
A method of multiple level resource reservation in a peer-to-peer protocol, comprising:
- making a resource reservation request across a series of adjacent nodes in one of a first layer and a second layer, the first layer and second layer being adjacent, the series of adjacent nodes having a starting node and an ending node;
- and
- passing one or more transmission parameter(s) between adjacent nodes in different ones of the first layer and the second layer according to an interworking function.
An apparatus configured for making multiple level resource reservation for a data stream via a peer-to-peer protocol, the apparatus comprising:
- a processor;
- and
- a memory having instructions stored thereon, wherein execution of the instruction cause the processor to:
- make a resource reservation request at a first layer;
- and
- subsequently requesting resource reservation request at a second layer, wherein the second layer is higher than the first layer;
- wherein, if the resource reservation request at the first layer fails, then failing the resource reservation at the second layer;
- wherein if the resource reservation request at the second layer fails, then withdrawing the resource reservation at the first layer.
