As an example, the socket of access view networking cable can be depending on networking physical interface, for receiving view networking report Text, internet physical interface (IP interface) can be the socket of access internet cable, for receiving interconnection network packet (IP report Text), virtual interface can be view networking tunnel virtual interface, and view networking report may be implemented in view networked server in such as Fig. 7 The conversion and transmitting-receiving of text and interconnection network packet.

Specifically, may include steps of:

Step 501, by view networking physical interface, reception is described to be directed to the view networked server depending on networked devices The view networking message that the internet device is sent；

When view networked devices send message to an internet device, internet device can be first determined depending on networked devices Physical address, and view networking message is generated for the physical address, this message can be three-tier message, may then pass through view Message transmissions to networked server is regarded, are regarded networking message so as to receive depending on networked server by networking physical interface.

Step 502, described to be converted to interconnection network packet depending on networking message for described depending on networked server, and pass through the void Quasi- interface is sent to the view networking bridge module；

It may include mac address table depending on networking bridge module as an example, by the way that MAC can be carried out depending on networking bridge module The inquiry of address, MAC (Media Access Control, medium access control) address, also known as hardware address, can be used to The position of the network equipment is defined, during the physical transfer of network bottom layer, data are transmitted through physical address to identify host 's.

When the processing of view networked server receives view networking message from regarding networking physical interface, due to the view networking report of acquisition The parameter of text and the parameter degree of coupling of view networked server are high, if directly forwarding the message after conversion, hold depending on networked server Easily message will be needed to be mistakenly considered the message of itself without being forwarded.

In the concrete realization, one or more virtual interfaces can be set in view networked server in advance, and one virtual Interface can be connect with one depending on networking physical interface, can be modeled as by the message that virtual interface transmits from virtual interface Middle acquisition, rather than obtained from depending on networking physical interface, the risk that message is blocked forwarding by view networked server is reduced, is improved The forwarding precision of message.

It is forwarded directly to internet physical interface by virtual interface, message content is carried out without again passing by protocol stack Logical process realizes the transparent transmission of message, has simplified the process of message transmissions

After by getting view networking message depending on networking physical interface, place first can be decoded to depending on networking message Reason generates interconnection network packet, and interconnection network packet is sent to virtual interface, will have virtual interface mark via virtual interface The interconnection network packet of knowledge is sent to view networking bridge module.

In an embodiment of the present invention, described to may include by described the step of being converted to interconnection network packet depending on networking message Following sub-step:

Specifically, protocol stack entrance function can be the function for carrying out protocol conversion in protocol stack.

For example, mac address table can be set in depending on networking bridge module in advance, to record multiple internet physical interfaces, And the MAC Address for the internet device being connect with internet physical interface.

After generating interconnection network packet, depending on the destination-mac address in the available message of networked server, determination is specifically connect The internet device of the interconnection network packet is received, and traverses mac address table, searches destination-mac address.

The interconnection network packet is sent to by sub-step 12 when the mac address table includes the destination-mac address The corresponding internet physical interface of the destination-mac address.

When in mac address table including destination-mac address, it can determine internet physical interface, and will be from virtually connecing The interconnection network packet obtained at mouthful is sent to internet physical interface.

In an alternative embodiment of the invention, described by view networking bridge module, the interconnection network packet is sent to The step of internet physical interface may include following sub-step:

Sub-step 21 obtains the destination-mac address in the interconnection network packet, and traverses in the view networking bridge module Mac address table；

Sub-step 22 carries out the destination-mac address when the mac address table does not include the destination-mac address Study, to obtain the destination-mac address；

After the mac address table that traversal regards in networking bridge module, if not finding destination-mac address, it can determine The interconnection network packet sent depending on not receiving the corresponding internet device of the destination-mac address before networking bridge module, is based on This, can learn destination-mac address, obtain destination-mac address.

Specifically, the virtual port of transmission interconnection network packet can be first determined depending on networked server, then to mac address table In all of the port in addition to the virtual port, send multiple test data packets comprising destination-mac address respectively.

When the corresponding target device of destination-mac address is after receiving the data packet, can be carried out for test data packet Response, sending response message to view networked server can recorde report depending on networked server after receiving this response message The MAC Address of target device in text, completes the study of destination-mac address.

And the other equipment other than target device are after receive test data packet, due to the target in test data packet MAC Address and the MAC Address of equipment itself are not inconsistent, then can abandon the test data packet, not respond.

Alternatively destination-mac address is learnt alternatively, can adopt.For example, can be with depending on networked server The message for waiting the corresponding target device of destination-mac address to upload is regarding after receiving the message from destination-mac address Mac address table in networking bridge module records this address, completes the study of destination-mac address.

Sub-step 23, after obtaining the destination-mac address, with being sent to the Destination MAC by the interconnection network packet The corresponding internet physical interface in location.
