Abstract
Systems and methods in a node in an Ethernet network include, responsive to enabling burst monitoring between the node and a peer node in the Ethernet network, obtaining rate and burst size information from the peer node; configuring a counter at a traffic disaggregation point based on the rate and the burst size information, wherein the counter is based on a dual token bucket that is used to count out-of-profile frames in excess of a Committed Information Rate (CIR); and detecting a burst based on the out-of-profile frames during a monitored time interval.
Claims18
A node in an Ethernet network, comprising:
- a plurality of ports;
- and
- circuitry configured to
- responsive to enabling burst monitoring between the node and a peer node in the Ethernet network, obtain rate and burst size information from the peer node,
- configure a counter at a traffic disaggregation point based on the rate and the burst size information, wherein the counter is based on a dual token bucket that is used to count out-of-profile frames in excess of a Committed Information Rate (CIR),
- detect a burst based on the out-of-profile frames during a monitored time interval,
- send a burst monitoring message to the peer node,
- obtain counter values from the peer node, and
- detect the burst at the peer node based on corresponding out-of-profile frames, from the counter values from the peer node, during a monitored time interval.
A non-transitory computer-readable medium having instructions stored thereon for programming a node in an Ethernet network to perform steps of:
- responsive to enabling burst monitoring between the node and a peer node in the Ethernet network, obtaining rate and burst size information from the peer node;
- configuring a counter at a traffic disaggregation point based on the rate and the burst size information, wherein the counter is based on a dual token bucket that is used to count out-of-profile frames in excess of a Committed Information Rate (CIR);
- detecting a burst based on the out-of-profile frames during a monitored time interval;
- sending a burst monitoring message to the peer mode,
- obtaining counter values from the peer node;
- and
- detecting the burst at the peer node based on corresponding out-of-profile frames, from the counter values from the peer node, during a monitored time interval.

- detect a burst based on the out-of-profile frames during a monitored time interval,
- wherein the counter is a first counter associated with a first service associated with the rate and burst size information, and wherein the circuitry is further configured to
- obtain second rate and burst size information for a second service,
- configure a second counter at the traffic disaggregation point based on the second rate and burst size information, and
- detect a burst on the second service based on corresponding out-of-profile frames during a monitored time interval.
