Abstract
A computer-readable storage medium (102) is provided for managing end-to-end QoS (Quality of Service) policies in a communication network (100). The storage medium includes computer instructions for establishing (302) a plurality of QoS domains (108) between a plurality of packet switching technologies (102, 106. 110) operating with disparate QoS policies, each QoS domain having an ingress and egress boundary, remapping (303) a QoS policy of each packet exchanged between the ingress boundaries of the plurality of QoS domains, and restoring (309) the QoS policy of each packet exchanged between the egress boundaries of the plurality of QoS domains.
Claims18
A non-transitory computer-readable storage medium for managing end-to-end QoS (Quality of Service) policies in a communication network, the storage medium comprising computer instructions for:
- establishing a plurality of QoS domains between a plurality of packet switching technologies operating with disparate QoS policies, each QoS domain having an ingress and egress boundary;
- monitoring traffic metrics of packets received from one or more of the plurality of QoS domains among the plurality of packet switching technologies at an ingress boundary, wherein the traffic metrics comprise a QoS policy for each of the received packets, traffic conditions, and the SLA packet traffic constraints of said plurality of QoS domains at said ingress boundary;
- remapping the QoS policy for each of the received packets according to said traffic metrics;
- and
- restoring the QoS policy of each packet exchanged between the egress boundaries of the plurality of QoS domains for the plurality of packet switching technologies;
- wherein the remapping of the QoS policy for each of the received packets is done according to said traffic metrics by lowering a transmission priority of the QoS policy of a packet when traffic conditions are above average and below peak traffic conditions established by the SLA and wherein storage medium comprises computer instructions for transmitting the packets with remapped QoS policies.
A provider edge for managing end-to-end QoS (Quality of Service) policies in a communication network, comprising:
- a packet router at the provider edge;
- and
- a processor for controlling operations of the packet router, wherein the processor is programmed to:
- establish a plurality of QoS domains between a plurality of packet switching technologies operating with disparate QoS policies, each QoS domain having an ingress and egress boundary;
- monitor traffic metrics of packets received from one or more of the plurality of QoS domains among the plurality of packet switching technologies at an ingress boundary;
- remap the QoS policy for each of the received packets according to said traffic metrics;
- and
- transmit the packets with remapped QoS policies;
- the traffic metrics comprise a QoS policy for each of the received packets, traffic conditions, and the SLA packet traffic constraints of said plurality of QoS domains at said ingress boundary and wherein the processor is programmed to remap the QoS policy for each of the received packets according to said traffic metrics by lowering a transmission priority of the QoS policy of a packet when traffic conditions are above average and below peak traffic conditions established by the SLA and wherein storage medium comprises computer instructions for transmitting the packets with remapped QoS policies.
A method for managing end-to-end QoS (Quality of Service) policies, comprising:
- monitoring traffic metrics of packets received from one or more of a plurality of QoS domains among a plurality of packet switching technologies at an ingress boundary;
- remapping a QoS policy for each of the received packets according to said traffic metrics and a service level agreement (SLA);
- transmitting the packets with remapped QoS policies;
- and
- restoring the QoS policy of each packet exchanged between the egress boundaries of the plurality of QoS domains for the plurality of packet switching technologies;
- wherein the remapping of the QoS policy for each of the received packets is done according to said traffic metrics by lowering a transmission priority of the QoS policy of a packet when traffic conditions are above average and below peak traffic conditions established by the SLA and wherein storage medium comprises computer instructions for transmitting the packets with remapped QoS policies.
