Description
Technical field
The present invention relates to virtual and network equipment field, in particular to one based on distributed virtual networkThe method of testing of equipment, Apparatus and system.
Background technology
(refer in particular to by the physical switches that connects physical server, with the inner difference void that is connected of physical host in virtual networkThe double layer network of the virtual switch composition of plan machine) in, (refer in particular to and be connected in virtual network in order to improve the network equipmentThree layers of processing and the network equipment of above flow) flexibility and versatility, the network equipment can be with the form of virtual machineRealize. For example virtual fire wall, or virtual attack-detection-device. Virtual network device generally can be connected to fortuneThe virtual switch module of row on host received and dispatched message.
Because virtual network scale can be carried out dynamic expansion, the void existing with separate unit virtual machine form according to actual needsIntend the variation that the network equipment cannot adapt to network size. In order to improve the extensibility of virtual network device, can adoptDistributed structure/architecture, i.e. a distributed virtual network device of many virtual machines composition, wherein, each virtual machineBe known as a subelement in virtual network device.
The subelement of virtual network device comprises forwarding subelement and controls subelement. The forwarding subelement of same type opensMove on different physical hosts, be responsible for processing the data traffic from virtual switch, according to pre-configured ruleData traffic is forwarded. Be responsible for coordinating each forwarding subelement, issue configuration information and same and control subelementWalk each state that forwards subelement etc. Thereby virtual network device can be increased according to the scale of virtual network orReduce the quantity that forwards subelement.
In the prior art, for the network equipment in the distributed network based on virtual machine, often adopt with test and passThe system network equipment identical method of testing is tested, and tests void by producing dissimilar and test traffic scaleIntend function and the performance indications of the network equipment.
In actual applications, in the implementation method of prior art, mainly comprise following two kinds:
Method one on the physical host at virtual network device place, is moved two test virtual machines simultaneously, logicalCross the performance of receiving and dispatching test traffic and testing each subelement.
