Fig. 1 transforms the sketch map of emulation preview method for power dispatch data network device upgrade of the present invention.
Embodiment
Below in conjunction with specific embodiment the present invention is further set forth.
Emulation preview method is transformed in power dispatch data network device upgrade based on SP Guru as shown in Figure 1, comprises the steps:
(1) through access network device information collecting server in the data dispatching net; Obtain all-network configuration of devices information in the data dispatching net; SP Guru sets up the network model of power dispatch data network according to the acquisition configuration information; Thereby simulate the annexation between the all-network equipment in the true data dispatching net, said configure packet includes network device node information and network link information; Facility information is collected the show/display instruction of the CLI that adopts SP Guru platform when server obtains network equipment information, can not produce any influence to actual power dispatch data network.Particularly; All-network equipment to power dispatch data network carries out Information Statistics; This statistical information comprises device name, equipment vendors and model, management ip address, login mode, port numbers, user name, password, superuser name, franchise password and SNMP community number; Then statistical information is consigned to information collecting server; Information collecting server will be selected suitable instruction to obtain the information of the network equipment according to the manufacturer and the model of concrete equipment, thereby obtain all-network configuration of devices information in the whole power dispatch data network according to login mode (like Telnet or SSH) and management ip address logging in network equipment then automatically; And set up nodal analysis method and the link model (nodal analysis method, link model belong to network topology model) that generates all-network equipment, obtain the annexation of nodal analysis method and link model.
(2) through key node (like core router) the configured port mirror image in power dispatch data network; Dispose the flow collection device; All datas on flows of key node all are mirrored in the flow collection device; And this mirror port is connected to the data on flows of obtaining (like a week, 1 year) power dispatch data network in a period of time in the computer that packet catcher is installed, set up the discharge model of power dispatch data network again according to said data on flows through SP Guru platform.Wherein a period of time refers to the one-period that data on flows changes, and this cycle is confirmed by the purpose of device upgrade modification scheme and emulation.
(3) based on the data dispatching network simulation model of said network model and discharge model formation, this simulation model is carried out the emulation preview that upgrading network equipment is transformed, particularly, the concrete steps of the emulation of upgrading network equipment transformation preview comprise:
