Description

A kind of adaptation method that is used for internet and wavelength-division multiplex system fusion

Invention field

The data that the present invention relates to the internet transmit the field, it is a kind of adaptation method that Internet Protocol (english abbreviation is IP) and wavelength division multiplexing system (english abbreviation is WDM) merge that is used for, the various high/medium/low end Ethernet switch, multi-service transport platform (english abbreviation is MSTP), the user side integrated access equipment and any the interconnect equipment relevant with the internet that are mainly used in various routers (core or high-end switch router, edge switch router, insert switch router), exchange based on grouping (bag).

Background technology

According to interrelated data, also there is not a kind of unified standard that realizes the adaptation method that internet and WDM merge at present in the world, each manufacturer realizes that the adaptation method that internet and WDM merge has following several mode during actual the use:

(1) adopt " peer-peer protocol " (english abbreviation is PPP) to add " high-level data link rules " (english abbreviation is HDLC);

(2) adopt SDH Link Access Procedure (english abbreviation is LAPS);

(3) mode of employing Generic Framing Procedure (english abbreviation is GFP).

Wherein first kind of adaptation method PPP+HDLC is a kind of method that is used for realizing IP and synchronous digital hierarchy (the English SDH of being) or Synchronous Optical Network (English is embodied as SONET) fusion that internet engineering task group (english abbreviation is IETF) defines, this scheme is by RFC2615, RFC1661, the RFC1662 definition of IETF, and RFC is request comment (English is Request For Comments).It is that X.85 ITU-T advises a kind of IP and the adaptation method of SDH that determine that second method adopts LAPS, and it is a kind of first method to be simplified the method for processing, and key element of its employing LAPS has replaced two key elements of PPP+HDLC; It is that the adaptation method of GFP is G.7041/Y.1303 a kind of adaptation method of proposed specifications of ITU-T that the third method promptly adopts Generic Framing Procedure, adopt GFP as data link layer protocol in this adaptation method, it can realize the adaptive of IP and SDH, IP and (english abbreviation is OTN), but the adapting protocol that still a kind of in essence point-to-point connects.Utilize above-mentioned three kinds of methods can realize the internet with utilize the SDH/SONET framing WDM adaptive.

In recent years, along with popularizing of computer technology, computer network is that the application of internet just progressively is penetrated into all trades and professions, make the mankind progressively enter informationized society, the internet in the application of modern society life various aspects more and more widely, the internet is also changing people's the life and the mode of thinking in very big convenient people.Unspecial during the initial design internet for designing a kind of transmission technology in the internet, on the contrary, one of its target is to shield various physical layer details, on the IP of network layer, can realize the interconnected of different physical networks, and the initial main purpose of internet designer is a kind of network that can transmit data such as text rather than real time business such as speech of design, this network using be the mode of doing one's best, therefore this network does not have service quality to guarantee, and the internet must rely on other network particularly telecommunications network could form a global network.On the other hand, people are in order to satisfy the requirement of voice service, set up a optical transport network that can be interconnected in the whole world, this optical-fiber network network mainly adopts SDH (Synchronous Digital Hierarchy) (English abbreviates SDH as) technology, SDH is SONET (SONET is the english abbreviation of Synchronous Optical Network) the North America correspondence, continuous increase along with network bandwidth requirements, requirement to backbone bandwidth also constantly increases, only rely on the SDH technology can not satisfy the requirement of people to backbone bandwidth, in this case, WDM technology is arisen at the historic moment, WDM technology has become a kind of main mode of expansion backbone bandwidth at present, how to reduce network layer, simplify network configuration, reduce network cost is people's pursuit always, therefore, people are conceiving a kind of method that can realize that IP and wavelength-division multiplex system merge always, and this method is referred to as IP overWDM.

The physics framing of optical wavelength mainly contains two kinds in the wdm system now, and a kind of is to adopt the SDH/SONET framing, a kind of employing ethernet frame structure, and wherein the wdm system of telecommunications backbone net mainly adopts the SDH/SONET frame structure.Because internet and SDH/SONET network itself are a kind of networks of different nature, this mainly be since the internet be a kind of employing packet switching, towards connectionless technology, it is that information is divided into packets of information different in size one by one, this packets of information is referred to as IP datagram, and each IP network node utilizes Routing Protocol to realize the forwarding of IP bag according to the purpose IP address in the IP header in the IP datagram.And SDH itself is promptly to be technology in order to make a phone call to design for transmit adopting time division multiplexing, circuit switching and connection-oriented traditional voice transmission, and SDH itself also is a kind of time-division multiplex technology.Above-mentioned three kinds of adaptation methods mainly are the adaptive problems that is used for internet and SDH/SONET, Internet Protocol is fitted on the WDM that adopts the SDH/SONET frame structure by these three kinds of adaptation methods, but above-mentioned adaptation procedure is problem mainly having solved is the problem that how transmits IP by SDH frame point-to-point on WDM, fusion aspect from IP network and WDM two macroreticulars, these three kinds of adaptation methods all come with some shortcomings and defective, mainly show:

(1) point-to-point that all belongs to of above-mentioned three kinds of adaptation methods connects solution, be that main benefit is that the point-to-point that has solved the IP bag transmits problem, but it is very complicated that these adaptation methods are handled, poor efficiency, when the IP bag being shone upon processing by these three kinds of modes as each node at network, each node all must be handled each IP bag, it is every through a node to be specially the IP bag, so just must carry out each IP bag once from one deck to three layer, a series of processing from three layers to one deck again, promptly from physical frame (SDH/SONET frame) signal, extract data link layer protocol frame (being respectively PPP+HDLC or LAPS or gfp frame), extract the IP bag from data link layer protocol frame (PPP+HDLC or LAPS or gfp frame) again, then according to the purpose IP address in the IP header in the IP bag, by Routing Protocol each IP bag is transmitted processing, promptly be forwarded to different ports, during forwarding at first the IP three layers seal the data link layer protocol (data link layer protocol of above three kinds of packaged types that installs to two layers, be respectively PPP+HDLC, LAPS or GFP), again the data link layer protocol frame that has encapsulated the IP bag is being encapsulated on the payload that the ground floor physical layer is the SDH/SONET frame then, just encapsulate PPP+HDLC or LAPS or gfp frame in the payload field of SDH/SONET frame, the not only very complicated but also poor efficiency of this processing, especially core node, the data volume of handling is very huge, actual showing, this has become a key factor that has a strong impact on the IP network quality.

(2) because these adaptation methods adopt is the point-to-point connection processing, and must handle each packet, therefore adopt the IP of above-mentioned three kinds of adaptation methods and the adaption system of WDM must carry out a series of electricity-light-electricity-light conversion, can not realize the direct exchange of optical wavelength, promptly full light exchange.

(3) because the ethernet network management function is more weak as not realizing that 50 milliseconds network protection switches (except the 10G Ethernet); and the data link layer protocol of above-mentioned three kinds of adaptation methods does not provide necessary network management and control system function yet; therefore can not be used to adopt the wdm system of ethernet frame structure with above-mentioned three kinds of adaptation methods; promptly used the network performance that can not promote the fusion of IP and Ethernet; increase the network processes level on the contrary, increase the complexity of network.

(4) though adopt the WDM network of SDH/SONET frame structure that the network protection switch function is provided; but because the IP network employing is according to Routing Protocol the IP bag to be transmitted processing; even the WDM network provides powerful network protection function like this; but adopt the IP network of this adaptation method also must recomputate route; this may cause packet loss on the one hand; be if carry important business such as real-time business on the other hand with IP; because the switching time reality of IP network in seconds, therefore may be difficult to satisfy the requirement of real time business.

(5) because IP network adopts is that two big class Routing Protocols are that Interior Gateway Protocol and Exterior Gateway Protocol realize the Route Selection that IP wraps, this mode does not have the traffic engineering ability, even may cause having between two nodes multilink to connect, but IP network may all transmit the IP bag by a link, it is congested to cause this link to produce, thereby cause packet loss, and this moment, other link was in idle condition.

(6) because above-mentioned adaptation method does not carry out any professional classification to the data business, and everybody is the same, all has identical priority, cause this IP network not have service quality to guarantee.

(7) for first kind of adaptive mode that promptly adopts PPP+HDLC and adopt LAPS, because what HDLC frame and LAPS frame adopted is that the specified byte achieve frame is delimited, need carry out transparent processing to the IP bag, this mode has two defectives: the one, and network security problem, if those spiteful people all are set to those specific two bytes (0X7D, 0X7E) to payload information, this doubles with regard to the flow that causes network so, gangs up against if adopt, and may cause network congestion; In addition, because these two kinds of adaptive modes all do not have error correction, if the frame delimiter byte occurs that wrong (theoretical probability that mistake occurs is 1/2 like this ⁸=1/256=0.00390625 promptly is about 3.9/1000ths), just may cause packet loss.

(8) adopt the IP network of above-mentioned three kinds of adaptation methods can say without any safety.As everyone knows, present IP network is without any fail safe, and the IP packet can be by intercepting, replace because above-mentioned adaptation method only is that the IP bag is mapped in the SDH payload field, these adaptation methods to the safety that improves IP network without any help.

(9) adaptation method of above-mentioned three kinds of IP and WDM can be used for IPv4 and IPv6, can realize that promptly adaptive the and IPv6 of IPv4 and SDH and SDH's is adaptive, but because IPv4 and IPv6 are incompatible, and owing to above-mentioned three kinds of adaptive modes all need be handled each IP bag in network layer, adopt three kinds of above-mentioned adaptation methods, make that IPv4 and IPv6 network can not be compatible.

(10) adopt in the network of above-mentioned adaptation method, traditional voice service is what to be separated with the IP network business, and generally believe that now following unified public network will adopt packet-switch technology, how these adaptation methods are for realizing the voice service packetizing, and the aspects such as fusion that make packetized voice business and IP network are without any help.

(1) processing is simple, efficient.Existing three kinds of IP belong to point-to-point with the WDM adaptation method and are connected solution, in this network, each node all need be through a series of from three layers of ground floors to the, a series of complex process from the 3rd layer to ground floor again, at first extract the HDLC frame from the SDH/SONET frame that is arranged in physical layer, perhaps LAPS frame or gfp frame, and then from HDLC frame extraction PPP frame, extract the IP bag from the PPP frame, perhaps extract the IP bag from the LAPS frame or from gfp frame, utilize Routing Protocol each IP bag to be transmitted processing then according to the purpose IP address in the IP packet head, according to different routes the IP bag is forwarded on the different links again after handling, determine the IP bag is forwarded to behind certain bar link the IP bag to be encapsulated into respectively that PPP is encapsulated into the HDLC frame then or IP sealed to install to LAPS or IP sealed again to install in the gfp frame according to Routing Protocol, again corresponding HDLC frame or LAPS frame or gfp frame are encapsulated in the SDH frame payload field, this processing is obviously very complicated, and poor efficiency.In contrast, adopt method provided by the invention, can simplify processing greatly, in realize the network of IP and the adaptive fusion of the WDM that adopts the SDH frame structure with DLP, only need at the edge of network access point, which country IP address (normally purpose IP address) according to the IP bag belongs to, which area, which node is classified, form a forwarding equivalence class, then the forwarding equivalence class of IP bag is mapped in the destination address code field of DLP frame, the principle of classification of IP forwarding equivalence class is to be divided into level Four, is respectively national code, domestic area code, station code and personal code work.So only need in the access point single treatment, IP wraps in the network of the whole IP that realizes with DLP and the adaptive fusion of WDM subsequently only needs can realize the forwarding that IP wraps according to the destination address sign indicating number in the DLP frame header, and when handling according to the sequential processes of national code, domestic area code, station code and personal code work, as long as one of discovery and this network node corresponding address sign indicating number are not inconsistent, stop to handle, directly transmit the great like this computational processing of simplifying network.

(2) can realize the direct exchange of optical wavelength.Because what existing three kinds of adaptation methods adopted is the point-to-point connection processing, and must handle each packet, therefore adopt the IP of above-mentioned three kinds of adaptation methods and the adaption system of WDM must carry out a series of electricity-light-electricity-light conversion, can not realize the exchange of optical wavelength, promptly full light exchange.Adopt method provided by the invention, because what adopt is the IP bag to be handled rather than each IP bag is handled with forwarding equivalence class, can be assigned to the IP bag of particular category like this at specific wavelength, each optical wavelength is equivalent to an interface link, specify a destination address sign indicating number therefore can for each wavelength, need not to carry out the light-electricity-light conversion of a series of complexity like this, can directly realize the exchange of optical wavelength, promptly can realize full light exchange.

(3) network for the IP that adopts the ethernet frame structure and WDM fusion provides powerful network management control function.Because the ethernet network management function is more weak as not realizing that 50 milliseconds network protection switches (except the 10G Ethernet); and the data link layer protocol of above-mentioned three kinds of adaptation methods does not provide necessary network management and control system function yet, therefore can not be used to adopt the wdm system of ethernet frame structure with above-mentioned three kinds of adaptation methods.And adopt data link layer protocol of the present invention---DLP; DLP provides abundant network control and management function; can realize that Topology Discovery, network switch protection (particularly 50 milliseconds protection switch functions), so the IP that proposes of the present invention and the adaptation method of WDM fusion can be used to adopt the wdm system of ethernet frame structure.

(4) provide particularly 50 milliseconds of protection switch functions of quick protective switch function.Though the SDH network provides the network protection switch function; but because the IP network employing is that Routing Protocol is transmitted processing to the IP bag; even adopt the WDM network of SDH frame structure that powerful network protection function is provided like this; but adopt the IP network of these three kinds of adaptation methods also must recomputate route; this may cause packet loss on the one hand; be if carry important business such as real-time business on the other hand with IP; because the switching time reality of IP network in seconds, therefore may be difficult to satisfy the requirement of real time business.Adopt method provided by the invention can realize that the quick protective switch of IP network switches as 50 milliseconds of protections; because one aspect of the present invention provides Topology Discovery and 50 milliseconds of protection switch functions at 2 layers; the forwarding of the IP bag among one side the present invention is the high speed classification transmission that realizes according to forwarding equivalence class in addition; need not each IP bag is handled, thereby adopt the present invention to switch ability for IP network provides the carrier-class network protection.

(5) provide the traffic management function, the traffic engineering ability particularly is provided.Because what IP network adopted is that two big class Routing Protocols are the Route Selection that Interior Gateway Protocol and Exterior Gateway Protocol realize the IP bag, this mode does not have the traffic engineering ability, even may cause having between two nodes multilink to connect, but IP network may all be forwarded to the IP bag on the link and transmit, it is congested to cause this link to produce, thereby cause packet loss, and this moment, other link was in idle condition.The invention provides powerful traffic engineering ability, the forwarding of IP bag is to transmit according to the IP forwarding equivalence class realization just of the destination address sign indicating number in the DLP frame, it is exactly the frame that is specifically designed to traffic management that DLP frame of the present invention has a kind of, it can provide powerful traffic engineering ability, the generation of above-mentioned situation can not occur.

(6) business is carried out classification, have service quality to guarantee.Because above-mentioned adaptation method does not carry out any professional classification to the data business, everybody is the same, all has identical priority, causes this IP network not have service quality to guarantee.The present invention has carried out the classification of science to the business of network, one class is the important real time business that quality of service requirement is arranged, one class is the business of doing one's best, priority treatment real time business during processing, and the flow of this processing also need rely on traffic engineering to monitor, thereby guaranteed the service quality of network.

(7) key that has improved network is strengthened property, reduces packet loss.For first kind of adaptive mode that promptly adopts PPP+HDLC and adopt LAPS, because what HDLC frame and LAPS frame adopted is that specified byte (0X7E) achieve frame is delimited, need carry out transparent processing to the IP bag, this mode has two defectives, the one, network security problem, those spiteful people only need payload information all is set to those specific two bytes (0X7D, 0X7E), and the flow of network just doubles so, gang up against if adopt, may cause network congestion; In addition, because these two kinds of adaptive modes all do not have error correction,, just may cause packet loss if wrong (wrong theoretical probability occurring is 1/28=1/256=0.00390625, promptly is about 3.9/1000ths) appears in the frame delimiter byte like this.The present invention adopts BCH (31,16) sign indicating number is realized the demarcation of DLP frame, what adopt is the matching relationship achieve frame demarcation of frame length field and frame length check field, the actual time frame length value that uses changes, need not to carry out transparent processing, and when the upper strata does not have data to send, the filling usefulness of frame gap be special idle frame, the potential safety hazard of having avoided PPP+HDLC or LAPS adaptation method to bring like this.In addition, BCH (31,16) sign indicating number provides powerful error correcting capability, can entangle 3 random errors at most, the present invention recommends to carry out the correction process of 2 random errors, same under the situation of no correction process, it is 1/28=1/256=0.00390625 that wrong theoretical probability delimit to appear in PPP+HDLC and the frame of adopting the adaptive mode of LAPS, promptly be about 3.9/1000ths, and adopt the theoretical probability of makeing mistakes of the present invention is 1/230=1/1073741824=0.000000000931, be about 9.3/10000000000ths, great like this minimizing because frame is delimited the wrong packet loss that may bring.

(8) security performance of raising network.Adopt the IP network of above-mentioned three kinds of adaptation methods can say without any safety.As everyone knows, present IP network is without any fail safe, and the IP packet can be by intercepting, replace because above-mentioned adaptation method only is that the IP bag is mapped in the SDH payload field, these adaptation methods to the safety that improves IP network without any help.The present invention provides powerful safety function from three aspects for IP network: the one, and utilize forwarding equivalence class to replace the IP address to realize the forwarding of IP bag, just utilize the IP address to its processing of classifying during processing, shielded real IP address like this at the edge access point; Two have provided a kind of encryption mechanism, can carry out encryption to the entire I P bag that comprises the IP address; Three have provided a kind of data authentication mechanism, can carry out authentication processing to original IP bag, generate a summary (being equivalent to a fingerprint) in company with sending, and can judge by the finger print information of identification IP bag whether the IP bag is revised by the people.Cryptographic algorithm and identifying algorithm can be to select flexibly in addition, determine by user's actual needs, and both can be the algorithm of standard, also can be the tailor-made algorithm of the tailor-made algorithm such as the military, financial institution, can reach the desirable security performance of user like this.

(9) realize the interconnected of IPv4 and IPv6 network.The adaptation method of above-mentioned three kinds of IP and WDM can be used for IPv4 and IPv6, promptly can realize WDM adaptive of the adaptive and IPv6 of IPv4 and the WDM that adopts the SDH frame structure and employing SDH frame structure, but because IPv4 and IPv6 are incompatible, and owing to above-mentioned three kinds of adaptive modes all need be handled each IP bag in network layer, adopt three kinds of above-mentioned adaptation methods, make that IPv4 and IPv6 network can not be compatible.Because what the present invention adopted is that forwarding equivalence class replaces the forwarding of IP address to the IP bag, only need to realize the forwarding of IP bag according to the destination address sign indicating number of data link layer protocol frame in network intermediate link, to IPv4 address and IPv6 address all is to carry out identical classification at different addresses to handle, and therefore can realize the compatibility of IPv4 and IPv6 network.

(10) can realize the integration of three networks of speech, data and video network.Adopt in the network of existing three kinds of adaptation methods, traditional voice service is what to be separated with the IP network business, and generally believe that now following unified public network will adopt packet-switch technology, how these adaptation methods are for realizing the voice service packetizing, and the aspects such as fusion that make packetized voice business and IP network are without any help.Adopt the present invention can realize the fusion of packet voice network and IP network, method is to utilize the business type field that defines in the DLP frame to realize multiple services encapsulation, utilize the destination address sign indicating number of DLP frame definition and the L2 address that the source address sign indicating number identifies different service types, for IP operation, identify the forwarding equivalence class of IP bag with destination address sign indicating number and source address sign indicating number, and for voice service, the telephone number of destination address sign indicating number and seedbed representation both call sides is (for the calling party, the corresponding called phone number of destination address sign indicating number in the DLP frame, the corresponding calling telephone number of source address sign indicating number, packet for the callee, situation just conversely), realized the fusion of IP network and voice network so on the one hand, and this fusion is not that voice network is superimposed upon on the IP network, the strong point of two networks has been brought into play in this fusion, has abandoned some shortcomings of two networks simultaneously.

of sign sends the function of sequencing, the payload information field of the traffic management frame of described new types of data link layer protocol can comprise a plurality of traffic management TLV information, for convenience the realization (generally adopt 32 as present chip, requiring traffic management frame total length like this is the integral multiple of 32 bits) of chip of the present invention, the length that requires whole traffic management frame is the integral multiple of 32 bits, if originally described new types of data link layer protocol traffic management frame length is not the integral multiple of 32 bits, then behind traffic management TLV, fill processing with the byte that is 0 entirely, the length of filling identifies with the byte form with the filling length field of described new types of data link layer protocol traffic management frame.
