Description

A kind of power communication integrated data network system and communication means thereof
Technical field
The present invention relates to a kind of power communication system, particularly relate to a kind of power communication integrated data network system and communication means thereof.
Background technology
The electric integrated business datum communication network scope of business comprises data, monitoring, production management, office, image, multimedia and voice service, mainly meets the traffic aggregation of various data service and the comprehensive carrying demand of multibusiness network.In order to ensure the safe, stable of communication network, emphasis communication station needs to carry out two first line of a couplet.For ensureing the stable of communication service, used Virtual Router Redundacy Protocol technology to carry out Hot Spare process in systems in which, once master malfunction, business immediately can be switched on standby equipment and work on.Owing to having used switch virtual interface technology in a network, Service Gateway address and Virtual Router Redundacy Protocol are configured on switch virtual interface, and switch virtual interface is condition controlled in the state forwarding this virtual local area network interface, this VLAN is forwarded when there being interface in switch, and this interface is in normal operating condition, then the state of this switch virtual interface is normal operating condition, on the equipment of integrated data network, we have carried out strict VLAN to each physics relaying transparent transmission interface and have forwarded control, so once there be physical interface state to be closed condition, the virtual interface that then all VLANs of this interface forwarding are corresponding all can become closed condition thereupon, so now Virtual Router Redundancy Protocol will in time by virtual net pipe transfer on stand-by equipment, to ensure the normal operation of business.
The mode that between current device, the bare fiber of interconnected employing is direct-connected; in running; the situation of the fiber break caused due to weather, the various factors such as artificial may be there is; if the optical fiber transceiving of two equipment rooms all interrupts; so terminal device interface will all be shut down; owing to deploying Virtual Router Redundancy Protocol, business can normally switch.But only broken one if there is a pair optical fiber, the equipment interface that so can receive one end of optical fiber can not be converted to closed condition, now will occur the situation of link single-pass.Because interface is not closed, so the VLAN(VLAN that forwards of this interface) corresponding SVI(switch virtual interface) interface also can not automatically switch to closed condition, and in fact this physical link had lost efficacy, data retransmission can not be carried out, now the main equipment of Virtual Router Redundancy Protocol has just become the equipment existed in name only, and stand-by equipment can not receive the survival information of autonomous device, so the state of oneself can be switched to mainly by for subsequent use by stand-by equipment automatically.At this moment will there are the main equipments of two same virtual gateways of carrying in network simultaneously, cause that route is unreachable, service disconnection.Have a strong impact on the normal operation of electric power system, therefore solve virtual router redundant protocol master that telecommunication optical fiber single-pass the causes technical barrier becoming puzzlement those skilled in the art for equipment switching failure problem.
Summary of the invention
