Abstract
A system for rate management of communication services. The system comprises at least one group of ports sharing a guaranteed-rate; and each of the group of ports determines an allowed-rate using at least one rate management policy.
Claims32
A system for rate management of communication services, comprising:
- at least one aggregation-group, comprising n ports sharing a guaranteed-rate G;
- and
- wherein each port in the aggregation-group determines an allowed-rate using at least one rate management policy.
A method of distributing communication messages among a group of ports sharing a guaranteed-rate fairly, in a communication network with an arbitrary topology, comprising the steps of:
- forming a sequence using the group of ports with a specified order;
- and
- each of the group of ports sending communication messages according to the order.
A system for rate management of aggregate-rate services, comprising:
- at least one aggregation-group comprising n ports sharing a guaranteed-rate G fairly;
- wherein each of the group of n ports is assigned a weighting factor Wi(i=1, . . . n);
- and
- wherein each port of the aggregation-group determines an allowed-rate using a rate-control method.
The system of claim 32, wherein the rate-control method comprises, for each local port:
- computing the allowed-rate as (Ilocal+WlocalB), if sum of ingress-rates of the aggregation-group is less than the guaranteed-rate;
- computing the allowed-rate as (MIN(Ilocal, WlocalX)+WlocalB), if sum of the ingress-rates of the aggregation-group is greater than or equal to the guaranteed-rate;
- and
- wherein B is an amount of rate increase, Ilocal is an ingress-rate of the local port, Wlocal is the weighting factor of the local port, X satisfies G≈ΣRi (for Ri/Wi<X)+ΣWiX (for Ri/Wi≧X), Ri is the ingress-rate of port i received in a rate-message from port i, and Wi is the weighting factor of port i.
