Abstract
A method and system for time stamping of packet data is described. Advantageous aspects of how time stamping of packet data can be achieved in both virtualized and cloud environments are detailed.
Claims14
A method of timestamping packet data, the method comprising:
- identifying from a network ingress node a first set of packets at a first point in time;
- identifying from the network ingress node a second set of packets at a second point in time;
- recording each of the first and second points in time and determining a time span between each of the first and second points in time;
- identifying the number of packets in the second set of packets and assigning an individual time stamp to individual ones of the packets, such that the second set of packets are each associated with a respective time stamp, and wherein the time stamps for the second set of packets are distributed within the time span between the first and second points in time;
- and
- wherein the packets are identified using a polling operation, wherein the polling operation at any one point in time does not effect a reading of all packets within the network ingress node, and wherein the polling operation provides a set of read packets and an indication of packets that were not read.

- and
- wherein the time span between each of the first and second points in time is related to an identified average rate at which packets enter the network ingress node.

- and
- wherein assigning individual ones of the packets with an individual time stamp comprises associating each packet with a time stamp pair representing a bounded interval for the second set of packets.
