Embodiment one

Referring to Fig. 5, a kind of step flow chart for regarding networked server switching method provided in an embodiment of the present invention is shown, This can be applied to view networking monitoring management platform depending on networked server switching method, can specifically include following steps:

Step 501: when the view networking monitoring management platform accesses view networking for the first time, receiving and networked by the first view The first networking request broadcast packet that server is sent, and networked by the second of the second view networked server transmission and request broadcast packet.

In embodiments of the present invention, can be responsible for entirely regarding networking depending on networking monitoring management platform (i.e. MServer) In all accesses monitoring device unified management and other third party's monitoring systems docking service.

Active and standby view networked server is deployed in depending on networking, it is possible to understand that ground, in the embodiment of the present invention, in the first view connection Network server is main view networked server, then second regards networked server as spare view networked server；And in the first view networking When server is spare view networked server, then second networked server is regarded as main view networked server, the embodiment of the present invention pair This is not subject to concrete restriction.

It is to be appreciated that the networking that the networking priority of main view networked server is higher than spare view networked server is preferential Grade, in the subsequent step of the embodiment of the present invention, be using first view networked server as main view networked server, specifically, It will be described in detail in following step.

The first view networked server of deployment and the second view networked server (i.e. active and standby view networked server) in view networking Later, first the request broadcast packet that networks can be sent to MServer simultaneously depending on networked server depending on networked server and second, i.e., First, which networks, requests broadcast packet and the second networking request broadcast packet.

When MServer accesses view networking for the first time, it can receive the first networking request broadcast packet and the second networking request be wide Packet is broadcast, and executes step 502.

Step 502: networking request broadcast packet according to the described first request broadcast packet and described second that networks, determine described the One view networked server and the corresponding priority of the second view networked server.

It include the corresponding priority of each view networked server in the request broadcast packet that networks.

The the first networking request broadcast packet and the second view networking clothes of the transmission of the first view networked server are received in MServer It is engaged in after the second networking request broadcast packet that device is sent, can network according to the first networking request broadcast packet and second and request broadcast Packet determines the first view networked server and the corresponding priority of the second view networking.

After determining the first view networked server and the corresponding priority of the second view networked server, step is executed 503。

Step 503: being higher than the preferential of the second view networked server in the priority of the first view networked server When grade, the network connection with the first view networked server is established.

When the priority of the first view networked server is higher than the priority of the second view networked server, then establish The network connection of the view networked server of MServer and first, i.e., at this point, first regards networked server to be deployed in view networking Main view networked server, and second regards networked server then as spare view networked server, then establishes the view of MServer and first and join Network connection between network server provides network service to regard networked server by first as MServer.

Certainly, in the concrete realization, can also using second view networked server as main view networked server, then at this point, The priority of second view networked server is higher than the priority of the first view networked server, then establishes the view of MServer and second and join Network connection between network server provides network service to regard networked server by second as MServer.

It is to be appreciated that above scheme only more fully understands the technical solution of the embodiment of the present invention and what is carried out retouches in detail It states, not as the sole limitation to the embodiment of the present invention.

And in practical applications, available pre-recorded each MAC Address, and obtain record each MAC Address when Between, and then according to the MAC Address of record and time of each MAC Address is recorded, it may thereby determine that out the view networking of last time networking The MAC Address of server.

After obtaining the MAC Address of the first view networked server of last time networking, step P2 is executed.

Step P2: the request broadcast packet that networks is received；It wherein, include each view the Internet services in the networking request broadcast packet The destination-mac address of device.

Destination-mac address refers in the networking request broadcast packet that each view networked server is sent received by MServer Include view networked server MAC Address.

After MServer is restarted, can receive dispose in advance it is each depending on networked server (be not limited only to two, can be with Greater than two) networking that sends requests broadcast packet, and so as to obtain, respectively view is networked included in each networkings request broadcast packet The destination-mac address of server, and execute step P3.

Step P3: the MAC Address is matched one by one with each destination-mac address.

It, can be by each destination-mac address and MAC Address (i.e. the first of last time networking after obtaining each destination-mac address Depending on the MAC Address of networked server) it is matched one by one.

In successful match, step P4 is executed, it is no to then follow the steps P5.

Step P4: in successful match, then the network connection with the first view networked server is established.

In successful match, indicate send it is each network request broadcast packet depending on include in networked server the first view networking Server then can preferentially select the first view networked server to establish network connection, namely in successful match, establish The network connection of the view networked server of MServer and first, regards networked server by first and provides network service as MServer.

Step P5: when it fails to match, then the priority of each view networked server is obtained, and networked from each view It selects the target of highest priority to regard networked server in server, establishes and connect with the network of target view networked server It connects.

When it fails to match, indicate to send in the view networked server of each request broadcast packet that networks not comprising the first view networking Server then can select the target of highest priority to regard networking from sending in each view networked server for networking request broadcast packet Server establishes the network with target view networked server, provides network clothes to regard networked server by target as MServer Business.

Certainly, when MServer executes reboot operation immediately, then other view networking can be selected to avoid MServer Server establishes network connection, specifically, is described in detail with embodiments discussed below.

In a preferred embodiment of an embodiment of the present invention, after above-mentioned steps 503, can also include:

Step M1: in the reboot operation for monitoring the view networking monitoring management platform, and first view is networked Under server and the second view normal situation of networked server, judge whether to receive by the first view the Internet services The third that device is sent, which networks, requests broadcast packet.
