The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the encapsulation format schematic diagram of existing network layer grouping in the IP Telecommunication Network;
Fig. 2 is the encapsulation format schematic diagram of improved network layer packet among the present invention;
Fig. 3 is the IPv4 data flow through IP Telecommunication Network the time, utilizes the present invention to realize the exemplary plot of intercommunication.
Embodiment
By analysis, the inventor thinks and finally can conclude on certain network communication protocol for the level of different business and access thereof.Therefore, the basic ideas of multi-protocols message adaptation method provided by the present invention are: at first increase protocol adaptation information and (be embodied as protocol code in the legacy network layer payload of the network layer packet of IP Telecommunication Network, data message as the FR agreement all has protocol code 111, the data message of File Transfer Protocol all has protocol code 112 etc.), know the protocol type of this data message so that make the recipient of data message, end equipment as the recipient is handled accordingly according to protocol stack, thereby realizes the carrying of multi-protocol data message.End equipment herein is meant initial equipment and the termination equipment that uses IP Telecommunication Network to carry out data interaction, for example is the apparatus for network node of IP Telecommunication Network or edge gateway equipment etc.
Figure 1 shows that the local encapsulation format of existing network layer grouping in the IP Telecommunication Network.As can be seen from Figure 1, this encapsulation format mainly is made up of three parts: link layer frame head, network layer packet header and network layer payload.Wherein, there is more excess room in the network layer payload part, can be used to place protocol adaptation information.For this reason, as shown in Figure 2, further mark off the subspace, be used for the type information of storage networking communication protocol at the head of network layer payload part.Therefore, this sub spaces can be called the protocol adaptation field according to its major function.This protocol adaptation field is used for the protocol type information of data content (this data content is placed on the back of protocol adaptation field in the network layer payload part) of stored messages, and other adapting operation information that will use of the possible network layer transmission service for using IP Telecommunication Network.
In IP Telecommunication Network, the data message that is sent to destination from source end external network transmits in the following way: at first, be positioned at the data message of edge gateway equipment (the abbreviating ED equipment as) reception of source end, the outer net destination address in the data message is delivered to address mapping device (abbreviating ADT equipment as) from external network; Address mapping device carries out the outer net destination address does not have address resolution and the mapping that is connected between the data net address with multiple location, and the multiple location of the destination ED equipment that obtains is not had the loopback of connection data net address to source end ED equipment; Source end ED equipment does not have the data of the connection net address destination ED equipment that sends datagram according to multiple location; Destination ED equipment receives data message, further transmits this data message according to the outer net destination address to external network, thereby makes data message finally arrive the destination.
In the process that data message transmits by IP Telecommunication Network, in fact the process of address transition is exactly the data message process of encapsulation/decapsulation again.With the mode of Business Stream (protocol streams) when entering IP Telecommunication Network when using the Network layer function of IP Telecommunication Network (or the end equipment of IP Telecommunication Network), which kind of network communication protocol information judgment data messages such as the datum plane that the edge gateway equipment of IP Telecommunication Network (or the network layer module in the end equipment of IP Telecommunication Network) can be by this data message place, communication port use from the data message of external network.When carrying out the data message encapsulation, according to the protocol type under the data message, determine employed network communication protocol coding, this network communication protocol encode seal is installed in the protocol adaptation field, data content (also can be data message itself) with message is encapsulated in the network layer payload simultaneously, sends in the IP Telecommunication Network.
The end equipment of IP Telecommunication Network receives after the corresponding data message, according to the protocol code in the protocol adaptation field, what carry in the judgement network layer payload is the data message of which kind of network communication protocol, carry out follow-up processing according to this network communication protocol then, send into corresponding external network and proceed transmission.
Below, realize that through IP Telecommunication Network intercommunication is that example is further detailed multi-protocols message adaptation method provided by the present invention with the IPv4 data flow.As shown in Figure 3, need be based on the user A of the N1 network of IPv4 agreement by the N2 network (as calling party B) of IP Telecommunication Network visit based on the IPv4 agreement.When the data flow from the N1 network flows to ED equipment 1, suppose that this data flow by authentication, is allowed to enter IP Telecommunication Network, ED equipment 1 knows that by the employed IPv4 port of this data flow the data flow that enters is based on the data flow of IPv4 agreement.Then, ED equipment 1 is behind the transfer resource of the remote outlet of having known this IPv4 data flow correspondence (being ED equipment 2) and the corresponding IP Telecommunication Network that will use, this IPv4 data flow is carried out address transition and encapsulation operation (can be further with reference to inventor's the ZL of patent formerly 200410070502.8 " in the IP Telecommunication Network system multiple location do not have is connected the method for packing that data network divides into groups "), and the protocol code that will identify the IPv4 agreement writes in the protocol adaptation field, then the IPv4 data flow is encapsulated in the network layer payload, transmits in IP Telecommunication Network inside.Like this, when the ED equipment 2 that is positioned at remote outlet is received data message from IP Telecommunication Network inside, before removing network layer encapsulation back, entering external network, by further parsing to the protocol adaptation field, can know that this data content is the IPv4 data flow, thereby the IPv4 protocol stack that can enter ED equipment 2 carries out subsequent treatment, and finally this IPv4 data flow enters into based on the continuous transmission of the N2 network trunk of IPv4 agreement.
In " towards the multi-protocols message transmitting method of IP Telecommunication Network " of applicant's separate case application, propose to use different datum planes (perhaps virtual circuit) to remove to carry dissimilar protocol massages.But this technical scheme need be distributed an independently datum plane for every kind of network communication protocol, and is therefore higher to the resource requirement on data plane.And utilize multi-protocols message adaptation method provided by the present invention, can realize effectively sharing of datum plane.When the resource of datum plane was nervous relatively, advantage was more obvious.In addition,,, can realize the agreement unaware, improve inner efficiency of transmission so the routing of IP Telecommunication Network inside does not need to be concerned about the processing of this partial content owing to be bearing protocol Adapted information in the legacy network layer payload of IP Telecommunication Network.Even when the network communication protocol of carrying is expanded, can the routing and switching function of routing not impacted yet.
More than the multi-protocols message adaptation method towards IP Telecommunication Network provided by the present invention is had been described in detail, but obvious specific implementation form of the present invention is not limited thereto.For the those skilled in the art in present technique field, the various conspicuous change of under the situation that does not deviate from claim scope of the present invention it being carried out is all within protection scope of the present invention.
