Multi-level resource reservation
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.
1. A method of multiple level resource reservation for a data stream in a peer-to-peer protocol, comprising:
generating, at a first network node, a first resource reservation request, wherein the first resource reservation request comprises a reservation associated with an N level network layer and comprises a value associated with a total accumulated delay along a path, including between the first network node and another network node;
transmitting from the first network node, to a second network node, the first resource reservation request;
generating, at the second network node, a second resource reservation request, wherein the second resource reservation request comprises a reservation associated with a N−1 level network layer and an updated value for the total accumulated delay along the path, including between the first network node and the second network node;
determinizing, at the second network node, that the updated value for the total accumulated delay is less than a pre-defined end-to-end aggregate transmission parameter; and
transmitting from the second network node, to a third network node, the second resource reservation request.
2. The method of claim 1 , further comprising:
generating, at the third network node, a third resource reservation request, wherein the third resource reservation request comprises a reservation associated with a N−1 level network layer and a second updated value for the total accumulated delay along the path, including between the second network node and the third network node;
determining, at the third network node, that the second updated value for the total accumulated delay exceeds the pre-defined end-to-end aggregate transmission parameter;
transmitting from the third network node, to the second network node, a release of reserved resources for the second resource reservation request; and
transmitting from the second network node, to the first network node, a release of reserved resources for the first resource reservation request.
3. The method of claim 2 , further comprising:
receiving, at the first network node, the release of reserved resources for the first resource reservation request;
generating, at the first network node, a fourth resource reservation request;
transmitting from the first network node, to a fourth network node, the fourth resource reservation request.
4. The method of claim 1 , further comprising:
generating, at the third network node, a third resource reservation request, wherein the third resource reservation request comprises a reservation associated with a N−1 level network layer and a second updated value for the total accumulated delay along the path, including between the second network node and the third network node;
determining, at the third network node, that the second updated value for the total accumulated delay is less than the pre-defined end-to-end aggregate transmission parameter;
transmitting from the third network node, to the second network node, a first reservation acknowledgment message; and
transmitting from the second network node, to the first network node, a second reservation acknowledgment message.
5. The method of claim 1 , wherein the first resource reservation request includes one or more transmission parameters.
6. The method of claim 1 , wherein the one or more transmission parameters include includes at least one of bandwidth, latency, and jitter.
7. The method of claim 1 , wherein the first resource reservation request is for a reserved data stream.
8. A system, comprising:
a first network node;
a second network node; and
a third network node;
wherein the first network node is configured to:
generate a first resource reservation request, wherein the first resource reservation request comprises a reservation associated with an N level network layer and comprises a value associated with a total accumulated delay along a path, including between the first network node and another network node; and
transmit to the second network node the first resource reservation request;
wherein the second network node is configured to:
generate a second resource reservation request, wherein the second resource reservation request comprises a reservation associated with a N−1 level network layer and an updated value for the total accumulated delay along the path, including between the first network node and the second network node;
determine that the updated value for the total accumulated delay is less than a pre-defined end-to-end aggregate transmission parameter; and
transmit to the third network node the second resource reservation request.
9. The system of claim 8 , wherein the third network node is configured to:
generate a third resource reservation request, wherein the third resource reservation request comprises a reservation associated with a N−1 level network layer and a second updated value for the total accumulated delay along the path, including between the second network node and the third network node;
determine that the second updated value for the total accumulated delay exceeds the pre-defined end-to-end aggregate transmission parameter; and
transmit to the second network node a release of reserved resources for the second resource reservation request.
10. The system of claim 9 , wherein the second network node is configured to:
transmit to the first network node a release of reserved resources for the first resource reservation request.
11. The system of claim 10 , wherein the first network node is configured to:
receive the release of reserved resources for the first resource reservation request;
generate a fourth resource reservation request; and
transmit to a fourth network node the fourth resource reservation request.
12. The system of claim 8 , wherein the third network node is configured to:
generate a third resource reservation request, wherein the third resource reservation request comprises a reservation associated with a N−1 level network layer and a second updated value for the total accumulated delay along the path, including between the second network node and the third network node;
determine that the second updated value for the total accumulated delay is less than the pre-defined end-to-end aggregate transmission parameter; and
transmit to the second network node, a first reservation acknowledgment message.
13. The system of claim 12 , wherein the second network node is configured to:
transmit to the first network node a second reservation acknowledgment message.
14. The system of claim 8 , wherein the first resource reservation request includes one or more transmission parameters.
15. The system of claim 14 , wherein the one or more transmission parameters include includes at least one of bandwidth, latency, and jitter.
16. The system of claim 8 , wherein the first resource reservation request is for a reserved data stream.
17. A method of multiple level resource reservation for a data stream in a peer-to-peer protocol, comprising:
generating, at a first network node, a first resource reservation request, wherein the first resource reservation request comprises a reservation associated with an N level network layer and comprises a value associated with a total accumulated delay along a path, including between the first network node and another network node;
transmitting from the first network node, to a second network node, the first resource reservation request;
generating, at the second network node, a second resource reservation request, wherein the second resource reservation request comprises a reservation associated with a N−1 level network layer and an updated value for the total accumulated delay along the path, including between the first network node and the second network node;
determinizing, at the second network node, that the updated value for the total accumulated delay is less than a pre-defined end-to-end aggregate transmission parameter;
