Description
Technical field
The present invention relates to network security and field of network management, specifically a kind of credible controlled network architecture and control method thereof, be used to realize to the expecting, can manage of network and constituent element and user behavior, for the credible controlled network of the next generation provides architecture.Belong to networking technology area.
Background technology
Nineteen eighty-three International Standards Organization (ISO:International Standardization Organizaition) has formulated Open System Interconnection (OSI:Open System Interconnection) reference model, and this model is being got irreplaceable effect aspect the standard computer network architectures.The ICP/IP protocol model comes from network architecture and the consensus standard of U.S. Department of Defense for its Advanced Research Projects Agency Network wide area network exploitation, with it serves as that the INTERNET that the basis is set up is present largest in the world computer network, just because of INTERNET's is widely-used, make TCP/IP become actual internet architecture standard, what adopt is connectionless end-to-end packet exchange, and " doing one's best " (best effort) is provided the design mechanism of service model.Along with Internet development, people follow the natural evolution of the Internet, have begun the research of next generation network.The main research contents that these network architecture and network control management are relevant is as follows:
1.OSI seven layer architectures
OSI is the abbreviation of Open System Interconnect, and it is interconnected to mean open system.International Standards Organization (International Standards Organization) has formulated osi model.This model is divided into 7 layers to the work of network service, is respectively physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer.1 to 4 layer is considered to low layer, and these layers move closely related with data.5 to 7 layers is high-rise, comprises the data of application-level.Each layer is responsible for a concrete job, then data is sent to down one deck.
The 1st layer is that physical layer (also being the ground floor in the osi model) in fact is exactly that wiring, optical fiber, network interface card and other are used for two network communication equipments are linked together.The 2nd layer is data link layer, and agreements such as operation Ethernet convert Frame to binary digit for 1 layer of processing.About MAC Address, switch or network interface card and driver, belong to the 2nd layer category.The 3rd layer is network layer, may also may also will pass through a lot of communication subnets through a lot of data links between two computers that communicate in computer network.The task of network layer is exactly to select route and routing node between suitable net, guarantees that data in time transmit.Network layer is formed packet with the frame that data link layer provides, and is packaged with network layer packet header in the bag, wherein contains logical address--the network address of Source Site and point of destination dot address.The 4th layer is the transport layer of process information, and the 4th layer data cell is also referred to as packet (packets), is responsible for obtaining full detail, and end-to-end telecommunication management is provided.The 5th layer is session layer, session layer and above high-level in, the unit that data transmit is referred to as message.Session layer does not participate in concrete transmission, and it provides the mechanism of communicating by letter between the foundation that comprises visit checking and session management and the maintenance application.As server authentication user login etc.The 6th layer is presentation layer, and this one deck mainly solves the syntactic representation problem of support information.It with the data of desire exchange from being suitable for a certain user's abstract syntax, being converted to being suitable for the transfer syntax that the OSI internal system is used.Formative expression and switched data services promptly are provided.The compression and decompression of data, work such as encryption and decryption all are responsible for by presentation layer.The 7th layer is also referred to as " application layer ", is specifically designed to application program.If application layer determine the character of communicating by letter between the process with satisfy user's needs and network is provided and user application software between the data of your a kind of concrete form of program needs of interface service.SMTP, DNS and FTP are 7 layer protocols
2. TCP/IP four layer architectures of the Internet
This agreement of TCP/IP is observed one four layers model concept: application layer, transport layer, network layer and physical interface layer.Wherein, physical interface layer is the basic unit of model, is responsible for the transmission and the reception of Frame, and frame is network information transfer unit independently.Physical interface layer is placed on frame on the net, or from network frame is taken off.The network layer interconnection protocol is dressed up the Internet datagram with data envelope, and the necessary routing algorithm of operation.Four interconnection protocols are arranged: Internet protocol IP here: be responsible for addressing and route data packets between main frame and network.ARP: obtain the hardware host address in the same physical network.Internet control messages agreement ICMP: send message, and the transmission mistake of report relevant data bag.Interconnected igmpinternet IGMP: brought to local multiplex broadcasting router report host groups member by the IP main frame.The transport layer host-host protocol provides communication session between computer.The selection of host-host protocol is decided according to data transfer mode.Two host-host protocol: transmission control protocol TCP: communicate to connect for application program provides reliably.Be suitable for once transmitting the situation of bulk data.And be applicable to and require the application program meet with a response.User Datagram Protoco (UDP) UDP: connectionless communication is provided, and has not guaranteed reliably to transmitting bag.Be suitable for once transmitting small amount of data, reliability then is responsible for by application layer.The application layer applications program is by this one deck accesses network.
Four layers of corresponding relation with seven layer architectures of OSI of ICP/IP protocol stack are: physical interface layer (corresponding OSI physical layer, data link layer), network layer (OSI network layer), transport layer (with the transport layer of OSI), application layer (OSI session layer, presentation layer, application layer)
3. the evolution of the Internet
In recent years, along with developing rapidly of Internet, the Internet has become network with fastest developing speed in three macroreticulars (the Internet, telecommunications network, television network).Four layer architectures (comprising physical interface layer, network layer, transport layer and application layer) of TCP/IP are deferred in the Internet, adopt towards connectionless packet-switch technology transmission data and the service of " doing one's best " is provided.Because it is towards connectionless characteristic, make the Internet in single transfer of data, have other networks incomparable advantage: the message transmission rate height; In addition, four layer architectures that the Internet adopted make it can carry out the interconnection of heterogeneous network, but this connectionless characteristic also is that the Internet is from the bottleneck of single data transmission network to the evolution of multiple service supporting net, " doing one's best " service characteristic that the Internet provides can not guarantee the reliability transmitted at all, and the retransmission delay time of being introduced by the transmission control protocol (TCP) of transport layer is for voice, videos etc. also are insupportable concerning the exigent business of real-time, though introduced the problem that some service quality (QoS) mechanism solves the internet transmission real time business, but these mechanism implement all to exist many problems on large scale network, can not fundamentally solve the problem of the Internet.In addition, be the fixed terminal service at the beginning of the Internet design, it is the mobility of support terminal well.
Therefore existing information network adopts the network service system structure of service-oriented, layering is built and is managed, newly-increased important service and technology all are to adopt one by one independently network level enforcement, every kind of business all has the network platform of oneself, not only the networking cost is very high, and because the management of each layer is to grow up under different historical conditions and applied environment with control method, there is very big difference in the control method of each layer, it is very complicated that the control of whole network and management become, and operation cost is very high.
Along with the differentiation of network architecture and the development of wide band multi-business mobile network technology, legacy network is to next generation network evolution.Next generation network is not a new network, merge and be based on existing multiple network evolution, current Telecoms has different views with computer bound pair next generation network, because original network foundation is obstructed, the route of evolution is obstructed, emphasis in the standard formulation process also has different with solution more, at Telecoms, the research contents of next generation network concentrates on transport layer and operation layer, on transport layer, mainly concentrate on ASON (ASON), on operation layer, mainly concentrate on soft switch, at computer circle next generation network is exactly NGI (Next Generation Internet), NGI does not have specific (special) requirements to transport layer, only need transport layer that high bandwidth as much as possible is provided, focus is at service bearer layer and operation layer, and the standard on the service bearer layer concentrates on the IPV6 agreement, concentrates on the intelligent terminal that adopts end-to-end control in the standard of operation layer.
In order to accelerate the standardized process of next generation network, ITU-T has set up next generation network focal group (FGNGN) in Geneva on May 6th, 2004, divide into business demand, architectural framework and mobility, the paraplasm amount, control and signaling, safety, network evolution, following 7 working groups such as packet network, held a meeting in average per 2 months, the standard that research and the formulation industry relevant with next generation network press for, now release comparatively concrete draft standard " the function structure model of FRA-NGN " draft standard and tentatively proposed some functional entitys of next generation network service layer and transport layer, this draft defines and analyzes the model of next generation network from the angle of logical functional entity, " FRMOB mobility functions demand " draft standard is divided between net the mobility of next generation network mobile, move in the net with Access Network is interior and move three kinds of situations, and proposed requirement and functional architecture mobile management; The business that " the manageable user network ability of CMIP " draft standard has proposed the IP network of management is to provide Internet resources control and management to the user, but managing I P net should have user grouping and multiple functions such as professional diversity, information access control and safety, mobile control and management, allocated bandwidth and SLA negotiation, end-to-end QoS configuration and priority profiles.
Computer circle standardization honor representative IETF also formulated a series of standard for next generation network, IPv6 is grouped in the bearing mode on the different medium, comprises Ethernet, point-to-point protocol (P2P) link, Fiber Distributed Data Interface (FDDI), token ring, ARCnet etc.; The IPv6 basic agreement comprises RFC2460 (internet protocol version 6), RFC2675 (the huge bag of IPv6), RFC2507 (compression of IPv6 head), IPv6 address related protocol, comprise RFC3513 (IPv6 address structure), RFC2374 (IPv6 polymerizable global unicast address), RFC1887 (distribution of IPv6 unicast address), RFC2375 (distribution of IPv6 multicast address) etc., professional related protocol comprises the SIP that is used to set up voice or video session, is used to control the Media Gateway Control Protocol of media gateway etc.
4.GENI plan and FIND plan
The American National Natural Science Fund is planning fundamentally to redesign the Internet at present, to solve existing variety of issue, make a Next Generation Internet that is more suitable for following computer environment, and announced " global network environmental survey " project (GENI) by name on August 22nd, 2005, National Science Foundation thinks that the research emphasis of Next Generation Internet is a networking security, mobile phone, wireless and sensor network is formed general calculation entironment jointly, therefore the GENI project mainly comprises a project and builds a test environment, the project of GENI mainly comprises: set up new Core Feature, design rebaptism mechanism, address and conforming architecture, design new network management example, strengthen the fail safe of existing architecture, designed for greater reliability, the security mechanism of accountability, design a new architecture, this architecture can with new wireless technology, optical communication technique, the general fit calculation technology is worked in coordination, design higher level service and extract structure, as information object, location-based service, identity network etc.; Set up new service and application, as safer, healthy and strong, controlled Distributed Application on a large scale, the principle and the pattern of design Distributed Application are set up new network architecture principle, the complexity of research network, scalability.
In December, 2005, at the Internet FIND (Future Internet Network Design) plan has been proposed, basic thought is that two tasks of the connectedness that provides and guarantee to submit of service are separated, network edge is separated the management and the use of resource user's control and management and network core, by defining the seamless link that suitable mapping service realizes the two.The same with the GENI plan, FIND intends the information network of fundamentally redesign a new generation, to solve the serious drawback that existing network exists at aspects such as fail safe, mobility, controllabilitys.
5. the 4D structure of network management
The major function that the CMU of the U.S. (CMU) proposes in the router now is reclassified as 4 planes, data (Data), distribution (Dissemination), finds (Discovery) and make a strategic decision (Decision), i.e. 4D.State information in the network is collected by the discovery plane, is responsible for these information is published to decision-making platform by the distribution plane then; Make a strategic decision the plane according to these information calculations suitable route and network configuration, and these results of decision are dealt into datum plane.Its elementary object is by centralized management and reorganizes key function, is expected to reach the complexity of simplifying network management and the purpose that makes the status discovery automation.
CONMan has further emphasized separating of control and management function and data forwarding function on the basis of 4D, expanded the thinking of the management channels of physical separation in its signaling system, though make and logically separate data and the shared physical link of management channels among the CONMan.
