Description

Realize the network architecture and method of land, sea, air, outer space network integration

Technical field

The present invention relates to Internet technical field more particularly to a kind of networks for realizing land, sea, air, outer space network integration Architectural framework and method.

Background technique

With the continuous development of network technology with the sustainable growth of number of users, internet is early had become in the world today most Big information sharing platform, it is that one of essential tool of people's life and work and various industries continue innovation New fulcrum.However, existing internet originates from later 1960s, original design intention is only the end for realizing trusted node Transmitted to end data, be unable to satisfy current people to the diversified demand of internet, such as safety is poor, poor expandability, can Many drawbacks such as pipe poor controllability, resource utilization are low, energy consumption is high are completely exposed.How to design and can satisfy current or even future The Next Generation Internet of user demand is one of the hot issue of countries in the world scholar research.

The essential reason of many serious shortcomings in existing internet is caused to be its " triple bindings " characteristic, i.e. " identity and position Set binding ", " resource and binding positions " and " control with forwarding bind ".Around the network rack of above-mentioned " triple bindings " separation Structure, i.e. " identity and position separation " network architecture, " resource is separated with the position " network architecture and " control and forward separating " net Network framework emerges one after another.

" identity and position separation " framework: the problem of so-called " identity and position binding ", refers to IP (Internet Protocol) the ambiguity of address, i.e. IP address represent the identity information of host in transport layer, represent the position of host in network layer Confidence breath.IP address ambiguity is to lead to that existing internet mobility is poor, safety is poor, the essential reason of poor expandability etc.. As its name suggests, the thought of " identity and position separation ", which refers to, decouples host identity information and location information using two marks, One identity identified for indicating host, can be the cryptographic Hash etc. of the IP address, public key that are not used in routing；Another mark For indicating the position of user, i.e. IP address." identity and position separation " mechanism can be divided into the scheme of Intrusion Detection based on host and network. The scheme of Intrusion Detection based on host directly modifies the protocol stack of host, but does not make an amendment to network system itself, such as HIP (Host Identity Protocol),SHIM6.Network-based scheme is repaired by address of the dedicated router to data packet The operation such as change, encapsulate, realizing the transformation of routing address, typical scheme has integrated identification network, LISP (Locator Identity Separation Protocol), GSE etc..The it is proposed of " identity and position separation " thought advantageously accounts for existing Mobile Internet poor expandability, safety is poor, does not support the drawbacks such as mobility, more local technologies.

" resource is separated with position " framework: internet is to be based on communicating end to end, and communicating pair must be known by other side's Physical location, i.e. IP address could establish transmission channel and carry out data transmission.Although Service Source has oneself independent name, Such as URL (Uniform Resource Locator), but its name usually contains service provider information, and service provider believes Breath is bound further through domain name system DNS (Domain Name System) with IP address one by one, ultimately causes resource and position Binding.In fact, for most Internet user, they more concerned about Service Source itself rather than its position, ICN The design concept of (Information-Centric Networking) is that needed for so that Internet user is directly retrieved them The information wanted, rather than the position where information, without considering the mapping of information to position.ICN directly names service content, The service name and service content present position information decouple, and user is facilitated to directly acquire oneself interested information.Meanwhile ICN introduces the concept of network-caching, i.e. router can flow through the service content of itself according to cache policy storage, facilitate other use Family obtains nearby, improves network transmission efficiency.In addition, ICN safety, mobility, the more local technologies the problems such as on it is more excellent Gesture.Representative ICN realization has NDN (Named Data Networking), DONA (Data-Oriented Network Architecture), NetInF (Network of Information), PURSUIT, COMET etc..

" control and forward separating " framework: existing internet will control plane and Forwarding plane coupling on the network node, While each node had both been responsible for Route Selection or operation data forwards.On the one hand, with the explosive growth of number of users, net Network is applied increasing, and more and more sophisticated functions are imparted into existing network, performance, the scalability of network node Deng by serious challenge；Another side, since network-based control level is distributed on each node, this makes network deployer difficult Efficiently to be managed it, increasingly complex, Demand-Oriented custom feature cannot achieve, lack flexibility and extension Property, new network is even more that can not dispose.For the growth requirement for adapting to the network new era, the network body of sustainable development is constructed System, the thought that " controlling and forwarding " separates gradually widely are paid close attention to.Open Signaling, Active from early stage Networking arrive again 4D, Forces (FORwarding and Control Element Separation), Ethane and SDN (Software-Defined Networking) of today, academia are constantly carrying out research and reality to the thought always It is existing, and SDN is even more to have obtained the support and approval of industrial circle, this undoubtedly brings strong power to the popularization of SDN.SDN will Forwarding plane is integrated on interchanger, control plane be deployed in one in logic centralization distribution physically so that controller Scalability problem become its inherent shortcoming, this is also one of the hot issue of current SDN research.

It can be seen that the Network Architecture Research around above-mentioned " triple bindings " separation is more deep, but still lack at present One can overcome the Future Internet framework of above-mentioned " triple bindings " simultaneously, many tight fundamentally to solve existing internet Weight drawback.

In addition, with the continuous development and innovation of satellite technology, satellite network due to its wide covering power increasingly Favored, how realizing land, sea, air, outer space network integration also will be the research hotspot problem of future network.

Integrated network supports end-to-end transmission mode and hop-by-hop transmission mode, communicating pair that can use according to the actual situation Different transmission modes.End-to-end transmission mode can be used existing TCP (Transmission Control Protocol) or The transport protocols such as UDP (User Datagram Protocol), are mainly used for Signalling exchange and compatible existing internet end is arrived The communication pattern at end.When using end-to-end transmission mode, it is double to be conducive to communication with [identity, port numbers] mark for transmission channel Identification, movement, parallel transmission of Fang Shiti etc..Hop-by-hop transmission mode is intended to obtain content itself nearby, logical without establishing transmission Road.In this mode, contain service identifiers in the service content request that user sends, receive the network of service content request message Entity need to check locally whether be stored with corresponding service content, have, be directly returned to requestor, otherwise continue to route.Service When content-data returns, the router with caching function can on-demand storage service content on the way.In service content request message It can add " demand for services description ", demand for services describes to define the minimum quality of service of requested service content.

Access net and core net can use oneself Routing Protocol and transport protocol according to own characteristic.Each network routing association Station location marker used in discussing is only limitted to use in oneself network, and corresponding station location marker length can self-defining.Border routing Device is responsible for the replacement of station location marker.Identity length used in each network transmission protocol can self-defining.For using not With the adjacent networks of transport protocol, border router need to carry out the conversion of transport protocol, identity length.

General message format used in integrated network is as shown in table 5, and wherein head includes source position mark, purpose position Set mark, service identifiers, source identity, purpose identity, source port number and destination slogan.Wherein, service identifiers, Source identity and purpose identity are option, and header carries on demand.

Table 5: general message format

No matter in core net or net is accessed, network entity is on demand to the position mapped system of belonging network and resource management System registry updates necessary information, and Service Source is then on demand to the service-seeking system of belonging network and resource management System registry updates necessary information.

Two, Network entity registers or update method in integrated network

User, server need to register or update to position mapped system by its couple in router (the first hop router) Its station location marker, station location marker are distributed by the couple in router that user, server are accessed.Server is also needed to service-seeking System and resource management system registration or the Service Source for updating its offer, router is then to the resource management system of belonging network Register its identity, station location marker, own hardware parameter information (such as network interface card bandwidth, memory size, central processing unit performance Deng) and the specific function that has, such as caching function, firewall functionality.In addition, router also needs the money to belonging network Management system regularly updates its use state (utilization rate of some or all hardware resource of router), and the latter is facilitated to perceive net The overall operation situation of network.

2.1 user's registrations or update method

2.1.1 the locating access net of user and ground core network network are connected directly scene

As shown in Fig. 2, user might as well be set as A, couple in router AR_A, identity A_ID, X is netted in access Station location marker be A_X-LOC；The border router for being mutually coupled with networking X and ground core network Y is BR_X-Y, the network numbering of access net X For X_Net-ID.User's registration or renewal process follow following steps:

Step 1, A send access request message to AR_A, and authentication-related information is carried, user side only uses identity It is communicated；

Step 2, AR_AA is extracted from request message_IDThe identity of certificate server verifying A is sent to authentication-related information；

The authentication result of A is returned to AR by step 3, certificate server_A；

Step 4, AR_AAuthentication result is transmitted to A；

Step 5, AR_AIt checks the authentication result that certificate server returns, if legal, then divides from the station location marker pond of itself With a station location marker A_X-LOCTo A, and record A_IDWith A_X-LOCBinding relationship.Later, AR_AThe position of X is netted to access instead of A It sets mapped system registration or updates A_IDWith A_X-LOCBinding relationship；

After the position mapped system that step 6, access net X receives registration or updates message, registration or update A_IDWith A_X-LOC's Binding relationship, and to AR_ASend confirmation message；

If A has occurred mobile and to be switched to access net X or A from other access nets be to access network for the first time, register or more New process also needs to complete following steps:

The position mapped system that step 7, access net X passes through BR_X-YTo the ground core net Y position mapped system registration or Update A_IDWith X_Net-IDBinding relationship；

Step 8, BR_X-YAfter receiving registration or updating message, the position mapped system of confirmation message to access net X is returned；

Step 9, BR_X-YThe position mapped system registration of core net Y or update A to the ground_IDWith X_Net-IDBinding relationship；

Step 10, ground core network Y position mapped system receive registration or update message after, registration or update A_IDWith X_Net-IDBinding relationship, and to BR_X-YSend confirmation message.

2.1.2 user is directly accessed Space Kernel net scene by LEO satellite or GEO satellite

In this scenario, user be usually land, ocean, Aeronautics and Astronautics, deep space etc. can not networking sole user, it is empty Between core net need to as its access network, guarantee its communication it is unimpeded.At this point, Space Kernel net can be considered as ground core network Net is accessed, user's registration or update method described in 2.1.1 are executed.

2.1.3 the locating access net of user and Space Kernel network are connected directly scene

User's registration or renewal process are identical as step described in 2.1.1, and difference is that Space Kernel net is receiving user's note Core net initiation registration or renewal process to the ground are also needed after volume or update.

As shown in figure 3, user might as well be set as A, couple in router AR_A, identity A_ID, X is netted in access Station location marker be A_X-LOC；The border router for being mutually coupled with networking X and Space Kernel net Y1 is BR_X-Y1；Interconnect Space Kernel net The border router of Y1 and ground core network Y2 is BR_Y1-Y2, the network numbering of access net X is X_Net-ID, the net of Space Kernel net Y1 Network number is Y1_Net-ID.User's registration or renewal process follow following steps:

Step 1, A send access request message to AR_A, and authentication-related information is carried, user side only uses identity It is communicated；

Step 2, AR_AA is extracted from request message_IDThe identity of certificate server verifying A is sent to authentication-related information；

The authentication result of A is informed AR by step 3, certificate server_A；

Step 4, AR_AAuthentication result is transmitted to A；

Step 5, AR_AIt checks the authentication result that certificate server returns, if legal, then distributes one from station location marker pond Station location marker A_X-LOCTo A, and record A_IDWith A_X-LOCBinding relationship.Later, AR_AIt is mapped instead of A to the position of access net X System registry updates A_IDWith A_X-LOCBinding relationship；

After the position mapped system that step 6, access net X receives registration or updates message, registration or update A_IDWith A_X-LOC's Binding relationship, and to AR_ASend confirmation message；

If movement occurs for A and is switched to access net X or A from other access nets to be to access network for the first time, registration or update Process also needs to complete following steps:

The position mapped system that step 7, access net X passes through BR_X-Y1It is registered to the position mapped system of Space Kernel net Y1 Or update A_IDWith X_Net-IDBinding relationship；

Step 8, BR_X-Y1After receiving registration or updating message, the position mapped system of confirmation message to access net X is returned；

Step 9, BR_X-Y1A is registered or updated to the position mapped system of Space Kernel net Y1_IDWith X_Net-IDBinding relationship；

Step 10, Space Kernel net Y1 position mapped system receive registration or update message after, registration or update A_IDWith X_Net-IDBinding relationship, and to BR_X-Y1Send confirmation message.

Step 11, Space Kernel net Y1 position mapped system pass through BR_Y1-Y2The position of core net Y2 maps system to the ground System registration updates A_IDWith Y1_Net-IDBinding relationship；

Step 12, BR_Y1-Y2After receiving registration or updating message, returns to confirmation message to the position of Space Kernel net Y1 and map System；

Step 13, BR_Y1-Y2The position mapped system registration of core net Y2 or update A to the ground_IDWith Y1_Net-IDBinding close System；

Step 14, ground core network Y2 position mapped system receive registration or update message after, registration or update A_IDWith Y1_Net-IDBinding relationship, and to BR_Y1-Y2Send confirmation message.

2.2 server registrations or update method

Server registration or update method are similar to user's registration or update method, and difference, which is server also, to be needed to service Inquiry system and resource management system registration update its Service Source.The side that server is registered or updated to position mapped system Method is identical with described in 2.1 sections, and this section repeats no more.Service Source is divided into service content and service function.

2.2.1 service content registration or update method

For the parsing for completing service content, server need to provide server itself to service-seeking system registry or update Identity, service description information SDI (Service Description Information, including service content title, Provider, keyword, abstract etc.) and obtain service identifiers.Server is accessed by its first hop router (couple in router) Network, the correlated process that the first hop router is completed service content registration as the agency of server or updated.

2.2.1.1 the locating access net of server and ground core network network are connected directly scene

As shown in figure 4, server might as well be set as A, couple in router AR_A, identity A_ID；It is mutually coupled with networking The border router of X and ground core network Y is BR_X-Y；Service identifiers are SID, service description information SDI, the net of access net X Network number is X_Net-ID.Server service content registration or renewal process follow following steps:
