Abstract

There are provided a system and method of assessing latency of forwarding data packets in virtual environment. The method comprises: upon specifying a transmitting monitoring point associated with a first virtual function (VF) and a receiving monitoring point associated with a second VF, generating packet signatures (SGs) for departing data packets, each uniquely characterized by respective SG D and for arriving data packets, each uniquely characterized by respective SG A ; maintaining a first data structure comprising a plurality of records related to departing packets associated with the first VF, each record informative of, at least, SG D and registered departure time T D of a given departing packet; responsive to registering arriving time T A of a given monitored arriving packet SG A associated with the second VF, searching the first data structure for a record matching a matching condition SG D = SG A ,; modifying the matching record to become informative of latency T=T A -T D and adding the modified record to a second data structure storing one or more modified records, each informative of latency measured for forwarding the packet SG D = SG A from the first monitoring point to the second monitoring point; and using data in the second data structure for assessing latency of forwarding packets from the ingress virtual port to the egress virtual port.
