The present invention relates to a method to monitor network performance in a computer (40) comprising at least one physical server (10) having a hardware machine (12) attached via a hypervisor (14) to a set of virtual machines (15,16,17). The method comprises steps like: - Measuring network performance parameters for selected packet flows (21,22,23) in transition between the hardware machine and the virtual machines. - Analyzing (59) the measured performance parameters. - Identifying a source of network degradation.
摘要:
An Admission Control Node and a method performed thereby for enabling a measurement between a first and a second device in a communication network, and a first device and a method performed thereby for performing the measurement between the first device and the second device in a communication network are provided. The method in the Admission Control Node comprises receiving, from the first device, a request for performing the measurement between the first and the second device and, determining segments comprised in a path between the first and the second device. The method also comprises determining a current measurement situation for the segments, and deciding to allow or reject the request for performing the measurement based on the current measurement situation for the segments. The method further comprises informing the first device about the decision of allowing or rejecting the request for performing the measurement.
