Embodiment
Utilize the existing flow structure of Linux, NAT information, routing iinformation, proposed the fast road under the NAT and transmitted thought, the fast road that the forwarded under the NAT is improved under the NAT is transmitted, improved the forwarding performance of system greatly.Through in flowing definition, increasing " fast road ", " route ", " flow label position ", realize the fast road repeater system under the NAT, to reach the purpose of quick transmission network message raising network equipment forwarding performance under NAT.Below will set forth concrete realizing method.
The connection of IP or TCP or UDP or other agreement in network; Finally all can be summed up as a stream in the network equipment; Information the most basic in the stream can comprise following attribute: source address, source port, destination address, destination interface, procotol, NAT etc., can expand in practical application as required.In the design of the fast road repeater system under NAT, in stream definition, increase attribute " fast road ", represent whether this stream is transferred to be transmitted by fast road to handle or transfer by the forwarded handling process processing of network layer by acquiescence; In the definition of stream, increase attribute " route ", represent the routing iinformation that this stream network of relation message is related, use during forwarding flow network of relation message, avoid the secondary routing inquiry, raising network message treatment effeciency in fast road; In the stream definition, increase attribute " flow label position "; Expression provides fast road forwarding flow to pay close attention to marker bit to the internet, applications module of paying close attention to this stream; If internet, applications module stream is paid close attention to flow label set; Then this internet, applications module permission is somebody's turn to do the transfer of stream network of relation message by the forwarding of fast road, otherwise this stream network of relation message need continue transfer by this internet, applications resume module, is somebody's turn to do the design of " flow label position " attribute; Can support the fast road forwarding decision of fast road repeater system, can support internet, applications that the relevant network message of particular stream is handled again.
To be example with the HTTP download below, the method for designing of fast road repeater system under the brief description NAT:
1) the Intranet client is initiated to connect through Transmission Control Protocol, is forwarded to public network server HTTP via the network equipment and connects.
2) TCP connect to initiate and during via device forwards, the network equipment is set up with NAT information according to the source address in the network message, source port, destination address, destination interface, procotol and is directed against this stream that is connected.Fast road repeater system is according to source/relevant informations such as order way address inquiry route and be tied to " route " attribute in the stream definition.
3) the internet, applications module as: fire compartment wall, keyword filtration, network behavior monitoring, authentification of user etc. when loading to fast road repeater system application " flow label position " attribute at stream.The internet, applications module; After handling through a series of network message; Confirm that not paying close attention to this flows follow-up network of relation message; Then can " flow label position " set of internet, applications module stream concern be represented that this internet, applications module allows fast road to transmit this and flows follow-up relevant network message, this flows follow-up relevant network message and no longer transfers this internet, applications resume module.
4) when all internet, applications modules of paying close attention to this stream; After " flow label position " set with the stream concern; Fast road repeater system integrated decision-making thinks that this stream can carry out fast road and transmit; " fast road " attribute that then will flow carries out set, and expression should will be handled by fast road repeater system by the follow-up network of relation message of stream.
5) all HTTP of this stream download relevant network message after reach equipment; At first whether set of " fast road " attribute of inspection stream; If set is then directly transferred fast road repeater system according to " NAT ", " route " attribute processing forward network message in the stream; Clock cycle when having shortened the CPU that the processing forward network message takies greatly; The efficient of handling network message in the network equipment unit interval will promote at double, and the HTTP downloading rate between Intranet client and public network server will obviously rise.
Fast road repeater system idiographic flow under the NAT is: 1. be input as the network message that needs forwarding; At first obtain the corresponding stream of network message; If obtain less than network message transfer network layer and transmit by the forwarded handling process of acquiescence so that the stream under setting up according to network message information, NAT information of address conversion by Linux conntrack module.Otherwise " fast road " attribute of stream under the inspection network message; If " fast road " attribute set of stream is then transferred by fast road repeater system processing forward network message under the network message, otherwise network message transfer network layer is transmitted by the forwarded handling process of acquiescence.
2. when network message transfer Internet is transmitted by the forwarded handling process of acquiescence,, then set up affiliated stream by Linux conntrack module message information Network Based, NAT information of address conversion earlier if the affiliated stream of this network message is set up.The internet, applications module of this stream of transfer concern simultaneously [as: fire compartment wall, keyword filtration etc.] the analyzing and processing network message; So that " flow label position " attribute to flowing under the network message carries out set, whether stream allows the forwarding of fast road and " fast road " the attribute set to flowing under the network message to the internet, applications module of paying close attention to this stream under the final decision network message.Simultaneously after via the network layer routing inquiry, " route " attribute that flows under the routing iinformation that network message is inquired and the network message carries out stream by associating information, avoids in fast road carrying out when repeater system is transmitted the processing network message secondary routing inquiry.
3. when network message is transferred by fast road repeater system processing forward network message, network message is carried out the NAT conversion, obtain network message routing iinformation transmission network message according to " route " attribute that flows under the network message by fast road repeater system.
The proposition of the method for designing of the fast road repeater system under the NAT; Be that the optimization that network equipment conventional network layer transmit to be handled the path of network message is simplified; Clock cycle when having shortened the CPU that the processing forward network message takies greatly, the efficient of handling network message in the network equipment CPU unit interval will promote at double.Fast road repeater system relevant treatment flow process under the NAT is following:
NAT shown in Fig. 1 transmits handling process in fast road, is input as network equipment transmission network message.At first obtain the stream under the network message, obtain less than or stream " fast road " attribute not the set network message then transfer by non-fast road, the fast road of NAT stream handling process and promptly transmit (like Fig. 2) by the forwarded handling process of acquiescence.If the stream under the network message " fast road " attribute set is then transferred the fast road of NAT repeater system and transmitted, correlation step is explained as follows: 1) NAT address transition wherein comprises conversion of SNAT source address or the conversion of DNAT destination address; 2) obtain stream " route " attribute, according to routing iinformation transmission network message; If stream " route " attribute is not related with routing iinformation, then network message is carried out routing inquiry; Successful inquiring is carried out the secondary routing inquiry then with routing iinformation and stream " route " Attribute Association when avoiding this stream network of relation message of follow-up forwarding, to improve routing forwarding efficient; If routing inquiry failure, then directly abandon network message and return.
NAT shown in Figure 2 transmits in fast road non-fast road stream handling process, is input as network equipment transmission network message.When network message obtain less than or stream " fast road " attribute not the set network message then transfer by non-fast road, the fast road of NAT stream handling process and promptly transmit by the forwarded handling process of acquiescence; Correlation step is explained as follows: 1) if network message is set up stream in the network equipment, then set up flow structure according to the source address in the network message, source port, destination address, destination interface, procotol; 2) whether the inspection network message need carry out the NAT conversion if needs then are provided with " NAT " attribute of stream, and network message are carried out NAT change at stream; 3) obtain stream " route " attribute, according to routing iinformation transmission network message; If stream " route " attribute is not related with routing iinformation, then network message is carried out routing inquiry.Successful inquiring is carried out the secondary routing inquiry then with routing iinformation and stream " route " Attribute Association when avoiding this stream network of relation message of follow-up forwarding.The routing inquiry failure then directly abandons network message and returns; Network message is transmitted handling process by default network and is handed over to the internet, applications module, carries out analyzing and processing.If the internet, applications module is no longer paid close attention to this stream subsequent network message; Then with internet, applications module flow label position " attribute carries out set; represent that the follow-up network of relation message of this stream need not to transfer this internet, applications resume module again, will continue to transfer this internet, applications resume module otherwise should flow follow-up network of relation message; 4) whether all set of all internet, applications module flow label bit attributes in the inspection stream; Do not paying close attention to the follow-up network of relation message of this stream if show all internet, applications modules; Then will flow " fast road " attribute set; This flows follow-up network of relation message will carry out fast road forwarding (like Fig. 1) by the fast road of NAT repeater system, need not to transfer by acquiescence and forwarded flow processing that treatment effeciency is low again.
Transmit the event response handling process like the fast road of Fig. 3 NAT; The fast road of input NAT repeater system external event; Correlation step is explained as follows: 1) internet, applications module application for registration stream " flow label position " attribute event; Fast road repeater system under the NAT provides " flow label position " attribute that closes beam for the internet, applications module, and the internet, applications module shows whether continue to pay close attention to the follow-up network of relation message of this stream through the set of " flow label position " attribute of convection current." flow label position " attribute of stream can be in the fast road repeater system application for registration under NAT during in initialization of internet, applications module; 2) the stream pin incident of dying, the connection of IP or TCP or UDP or other agreement in network, accomplish transfer of data or abnormal conditions can be with connection closed, the stream that network device internal is corresponding with this connection also can be sold thereupon and die.If there is record in oneself this stream in fast road repeater system, then should flows from fast road repeater system and delete; 3) network equipment routing change incident.Circulation overcurrent " route " attribute that fast road is transmitted in the fast road repeater system is related with routing iinformation, carries out the secondary routing inquiry when avoiding this stream network of relation message of follow-up forwarding, to improve routing forwarding efficient.Therefore when network equipment routing change, fast road repeater system needs " route " attribute of the stream of fast road forwarding is refreshed, and guarantees that this flows follow-up network of relation message and transmits by correct routing iinformation.
Though the design of the fast road repeater system under the NAT has promoted network equipment forwarding performance greatly, certain connection under some application scenarios can't be transmitted through fast road repeater system.For example Intranet is built ftp server; The user adopt port mapping technology access network equipment public network IP v4 address so that the visit Intranet build the ftp server data download time; The FTP data connect and can transmit through the fast road repeater system under the NAT, and the FTP control connection must be transferred by ALG ALG resume module modification network message application layer relevant field and can't transfer by the fast road repeater system under the NAT and transmit.For the similar application scene, the fast road repeater system under the NAT needs correct identification control stream and data flow, and corresponding pass-through mode is adopted in dissimilar connections, to reach the optimization forward-path, improves the purpose of network equipment forwarding performance.
Can consider simultaneously the ALG ALG module integrated to NAT repeater system inside, fast road down; But along with the fast road repeater system internal integration ALG ALG module under the NAT increases gradually, with the fast road repeater system network message forward efficiency that greatly influences under the NAT.Therefore to some special application scenarioss, the fast road repeater system under the NAT should be distinguished and treat, to reach the purpose of efficient, quick transmission network message.
In sum, the present invention proposes a kind of novel forwarding model, the original repeater system of the network equipment the basis on newly speed repeater system.In the stream definition, increase " fast road " attribute, identify fast road forwarding flow.In the stream definition, increase " route " attribute, use when related stream is sent out by information, avoid secondary inquiry route in repeating process.In the stream definition, increase " flow label position " attribute, take into account the processing that the internet, applications module is closed beam network of relation message.Legacy network devices transmit is handled the optimization in the path of network message and simplified, the clock cycle when having shortened the CPU that the processing forward network message takies greatly, the efficient of handling network message in the network equipment CPU unit interval will promote at double.
What need understand is: the above only is a preferred implementation of the present invention; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
