Wherein, the type of service of network message has predetermined one-to-one relationship, network message with outer net label
Type of service and privately owned label there is predetermined one-to-one relationship.
Above-mentioned gateway provided in an embodiment of the present invention is suitable for for smart machine providing multiple business type network, and existing
The scheme that the network of each type of service is tied to a lan interfaces respectively, the embodiment of the present invention is needed to provide in technology
Gateway the network of multiple business type can be both corresponded to the same mixing industry by the way of changing virtual local area network tags
Business lan interfaces are achieved in multiple business and realize transmission by an interface, avoid the strong dependence between business and hardware
Relationship.Even if increasing more outer nets (carrier network) in practical applications all haves no need to change gateway hardware, enhance hard
The versatility of part design, reduces hardware modifications cost.
Specifically, above-mentioned network message processing method provided in an embodiment of the present invention, a variety of industry can be transmitted by being directed to
The mixed service lan interfaces of service type network need the smart machine of multiple business type to answer correspondingly, connecting the interface
This has processing capacity corresponding with gateway.Gateway can be transmitted to a variety of industry of smart machine by mixed service lan interfaces
The network message of service type, and the network message of each type of service corresponds to a kind of privately owned label respectively, then smart machine
The corresponding type of service with network message is needed in the network message sent by above-mentioned mixed service lan interfaces
Corresponding privately owned label.And before using above-mentioned network message processing method provided in an embodiment of the present invention, it needs first
Determine the agreement relationship between network mark label other than type of service and privately owned label.Since outer net is generally various operator's nets
Network, and with the virtual office that differentiated service in carrier network interchanger is set in the network message that carrier network is transmitted
Domain network mark label, the virtual local area network tags are known, are referred to as in embodiments of the present invention " outer net label "；And privately owned label
Be then gateway according to network traffic types is not all virtual local area network tags that each type of service is configured, the privately owned label
It can be configured and change according to actual needs, after the correspondence of privately owned label and type of service is determined,
These privately owned labels are then carried by the network message that mixed service lan interfaces transmit, it can be true according to the difference of privately owned label
Surely transmit be which kind of type of service network message.For example, for the network message of IPTV service, outer net label can be vlan
B, and gateway can be vlan 666 for the privately owned label of its configuration.
From the point of view of gateway side, received network message, which is divided into, to be needed to be forwarded under mixed service lan interfaces
Row network message and the uplink network message for coming from mixed service lan interfaces, will forwarding after downlink network Message processing
To mixed service lan interfaces, uplink network Message processing aftereffect fatal position is forwarded to Wide Area Network interface.Identifying reception
After the virtual local area network tags of network message, for downlink network message, the service class according to the downlink network message is needed
Type stamps the privately owned label for being only applicable to this gateway, if the downlink network message has carried the outer net for being adapted to carrier network
The outer net tag modification is then that privately owned label is forwarded to mixed service lan interfaces again by label.It is connect for example, coming from WAN
The virtual local area network tags of the downlink network message of the Internet service of mouth are vlan A, then need to repair vlan A before turning
It is forwarded to LAN ' interfaces after being changed to vlan 0.For uplink network message, then the privately owned label carried is needed to revert to suitable
It should be forwarded to Wide Area Network interface again in the outer net label of carrier network.For example, coming from the upper of the IPTV service of LAN ' interfaces
The virtual local area network tags of row network message are vlan 666, then turn after needing for vlan 666 to be revised as vlan B before turning
It is sent to wan interface.
Make the network message of various businesses type all have its corresponding privately owned label in the Home Network Central Shanxi Plain as a result, mixes
Business lan interfaces can only no longer bind the network of single type of service, but can be adapted for the net of multiple business type
Network shares the interface.And be that corresponding privately owned label is arranged in the network messages of different service types, then it can be there are a variety of industry
When the network of service type, data broadcasting is prevented, reduces the expense of system resource.
In alternatively possible existing application scenarios, the network message of the carrier network of some outer net access gatewaies
Virtual local area network tags are default, then it is directed to such case, above-mentioned network message processing method provided in an embodiment of the present invention, and also
Including：
It is downlink net when the outer net label for the downlink network message for needing to be forwarded to mixed service lan interfaces is default
After network message increases the first privately owned label corresponding with the type of service of the downlink network message, it is forwarded to mixed service local
Network interface；
It, will when the virtual local area network tags of the uplink network message from mixing lan interfaces are the first privately owned label
After first privately owned label removal of uplink network message, it is forwarded to Wide Area Network interface.
The above situation is a kind of special circumstances in above-mentioned network message processing method, even if the virtual LAN of network message
Label is default, which still falls within the network message of a certain type of service, therefore for the network of this type of service
Still a corresponding privately owned label, i.e., the above-mentioned first privately owned label, then receiving can be arranged for it in message, the embodiment of the present invention
In the downlink network message of this type of service, connect to be forwarded to mixed service LAN after its first privately owned label of increase
Mouthful.And in the uplink network message for receiving this type of service, then it needs to be forwarded to after the first privately owned label removal wide
Domain network interface.
Further, the network message processing method of above-mentioned gateway provided in an embodiment of the present invention, is particularly suitable for simultaneously
The case where there are multiple business type carrier networks, then for receive need be forwarded to mixed service lan interfaces
When network message includes the downlink network message of at least two types of service, above-mentioned step S203 can specifically include：
It is successively that each downlink network message is original according to the correspondence of the type of service and privately owned label of network message
Outer net tag modification is privately owned label corresponding with each type of service of downlink network message.
Before running above-mentioned gateway provided in an embodiment of the present invention, configured and each industry for the network of various businesses type
The corresponding privately owned label of service type, which is only applicable to the gateway, including two or more type of service
Network when, need not be one physical local area network interface of network bound of each type of service again, and only by each type of service
The virtual local area network tags of network message be revised as corresponding privately owned label, the network message of such multiple business type
The same physical local area network interface can be shared, in embodiments of the present invention referred to as mixed service lan interfaces.
It, can be according to the significance level of type of service since there are the network messages of multiple business type to forward simultaneously
Priority is forwarded, then above-mentioned step S204, can specifically include：
By virtual local area network tags treated each downlink network message according to the priority of predetermined type of service
It is forwarded to mixed service lan interfaces successively.
For different application scenarios, the priority of the network message of each type of service is upper different in setting, for example,
When the network message terminal of each type of service of forwarding needs to be transmitted to smart television, then the network message of IPTV service is excellent
The highest that first grade should be set to protect smart television that the function of broadcasting TV may be implemented first, and then realizes online
Etc. other functions.Therefore, in practical applications, the network message that each type of service is flexibly set according to particular condition in use is needed
Forwarding priority.
Correspondingly, include the uplink of at least two business in the network message from mixed service lan interfaces of reception
When network message, above-mentioned step S205 can specifically include：
According to the correspondence of the type of service and outer net label of network message, successively by the privately owned of each uplink network message
Label reverts to outer net label corresponding with each type of service of uplink network message.
As described above, when the uplink network message of the type of service including two or more needs forwarding, for
The network message of each type of service has the virtual local area network tags that its script is suitable for each outer net, therefore by these networks
Message is forwarded to before Wide Area Network interface, needs the privately owned label of each network message reverting to its original outer net label again
Forwarded upstream.
It similarly, can be according to the significance level of type of service when being forwarded simultaneously there are the network message of multiple business type
Priority be forwarded, then above-mentioned step S206, can specifically include：
By virtual local area network tags treated each uplink network message according to the priority of predetermined type of service
It is forwarded to Wide Area Network interface successively.
As described above, in practical applications, needing the network report that each type of service is flexibly arranged according to particular condition in use
The forwarding priority of text.The embodiment of the present invention not to type of service and its priority orders specifically limited.
