Embodiment
Below in conjunction with accompanying drawing and embodiment of the present invention, the present invention is described in further detail:
1. componentization network protocol processing system
According to function and requirements such as transmission control, resource management, routing iinformation maintenances, the componentization procotol is divided into different construction part modules with whole network.Componentization protocol architecture framework is as shown in Figure 1.Relatively fix (as the part that transmits and receive data) according to call relation between network application characteristics partial component; But between each member of this architecture is loose coupling; Can be that application-specific is provided services on the Internet through component adaptation device flexible combination member according to application demand, the component adaptation device can be introduced in the back in detail.
Because the componentization design, the expansion of existing business demand can be carried out the member expansion like route, QoS, network security etc.In the face of the new application that possibly occur from now on, the componentization design no longer is as hierarchical network, runs into new demand and new function constantly " patch installing ", but according to new application demand, adds new building blocks of function and new design philosophy (between the member Rankine-Hugoniot relations etc.) flexibly
2. componentization protocol system model
The componentization protocol system is divided into three major parts: component base, component information storehouse and component adaptation device.Through to the wireless network protocol componentization, form big component base, all component information are kept in the component information storehouse; Component base and component information storehouse are managed by the unification of component adaptation device.When calling network function module, the data that application program produces are direct and the component adaptation device is mutual each other.The application program that produces business datum need not be concerned about how to go to obtain the function services component, and only need fill in the attribute configuration inventory that portion is called as the member call list, and submit to the component adaptation device according to the attribute configuration tabulation of component adaptation device defined.This attribute configuration tabulation comprises: the member numbering, be used to represent the member function type, and like route, transmission, QoS etc.; Member numbering is used to represent different member realizations; The member order information that is called; Whether member must be called in this service provides; And the attribute information relevant with member, be beneficial to user's personalized customization.
Table 1, attribute configuration tabulation
| Property Name | Attribute description | Whether attribute is necessary |
| The member numbering | Expression member function type | Be |
| Member numbering | Represent concrete member realization | Be |
| The member recalls information | Represent that this member calls order in whole service provides | Be |
| Member calls requirement | Whether the expression member must be called | Not |
| Structure attribute information | By the user according to the self-demand personalized customization | Not |
After the component adaptation device was received the attribute configuration inventory, each item concrete configuration property value in the analysis configuration inventory was chosen different component intelligently in component base, formed a service of satisfying application demand, for application program is provided services on the Internet.
1) component base
Component base is the concrete realization according to the various members of network function division.In the component base, each class A of geometric unitA can comprise various implementation, and every kind of realization is divided into constructed fuction again and explains function, and constructed fuction is used for transmit leg, explains that function is used for the recipient.The constructed fuction has here been used for reference constructed fuction and the destructor function thought of mentioning in the object-oriented with explaining function, but also inequality with them.Tabulation realizes calling constructed fuction according to attribute configuration by the component adaptation device, accomplishes this building blocks of function data are wrapped in required operations of carrying out in the process of transmitting, and first-class as adding packet, taking to operate the implementor can define according to real needs voluntarily; The explanation function is realized calling according to the packet header packet information by the component adaptation device, accomplishes this building blocks of function required operations of carrying out in the packet receiving course, as explaining packet header, deletion packet header etc.Through using constructed fuction and explaining function, make them become building blocks of function and outside mutual interface, so not only the realization of each class A of geometric unitA can be deferred to unified interface, and the difference of each class A of geometric unitA realizes also can deferring to unified interface easily.Such as for the route service member with the transmission services component; Set up the unified standard interface according to its function for this class A of geometric unitA; Route service member 1, route service member 2, transmission services component 1,2 differences of transmission services component only are inner specific algorithm realization so, and interface is identical.Unified interface is built more flexibly and standard component base inside.All members all leave in to prepare against in the component base to be used, and according to the standard that unified interface provided, the interpolation of component base, unloading, renewal and maintenance are all very convenient, guarantee member integral uniform property.
2) component information storehouse
The component information storehouse mainly is the ability that improves component adaptation device Retrieval Component.The concrete realization of each member all comprises a member head, and the content in the member head is by the version information of member; The type of member; The functional description information of member; The measurement index of member; This index can be set with different realizations according to the different functions member flexibly; As can being the routing table rise time, can be network in the utilance etc. that does not take place under the congestion situation for this measurement index of member of realizing congested control for this measurement index of member of realizing routing function.The set of all member heads forms the component information storehouse.The unification of member head is managed by the component adaptation device.Member realization of every interpolation is just added the member head of correspondence to the component information storehouse simultaneously.Only need remove the realization of member during unloading earlier, the component adaptation device will realize that corresponding member head deletes from the component information storehouse then.The renewal of member need be operated in component base and component information storehouse by the component adaptation device simultaneously.
3) component adaptation device
The component adaptation device is the control centre of whole procotol, and functions such as member scheduling, renewal and maintenance are born in its connecting elements storehouse and component information storehouse.
The attribute configuration that the component adaptation device is submitted to according to application program, the Retrieval Component information bank, the decision network function is accepted or rejected; From selected function, selecting the concrete member of this function then is that application data provides service.
The major function that adapter is accomplished is perhaps to call the constructed fuction of suitable building blocks of function and explain function in receiving terminal packet packet header according to the attribute configuration tabulation of transmitting terminal.According to accomplishing function, the component adaptation device can be divided into constructor part and interpreter part.
Constructor is the concrete realization of component adaptation device at transmitting terminal.It provides good transmission service interface to application data, and the attribute configuration list information that application data to be sent is submitted to is analyzed and handled, and promptly compares the member header in attribute configuration list information and the component information storehouse.If have attribute configuration list information and member header to be complementary then from the component information storehouse, obtain building blocks of function information; The constructed fuction of member is realized the function service in the last component invoking storehouse; Groundwork comprises the modification of packet packet header, adds new data packets packet header etc.
Interpreter is that the component adaptation device is specifically realized at receiving terminal.It is through calling framing member and link management member from the network interface reading of data; Then explain successively and receive packet packet header according to packet packet header order; According to member numbering and the sub-number information inquiry component of member storehouse that packet header provides, the letter of explanation that calls suitable member counts up to into service.If this packets need is transmitted; Then in the process of decryption bag packet header, need generate the attribute configuration tabulation of transmitting packets need simultaneously; This attribute list is identical with the attribute configuration list content that the source end generates; Forward node can be according to demand to the member recalls information in the middle of difference was, member calls requirement and structure attribute information etc. and makes amendment, and reaches the purpose of improving service quality.
4) system works model
After having introduced system's part in detail, will provide the system works model below.
The model is to be initiated according to own network demand for services by the user.At first the user fills in the attribute configuration tabulation according to self-demand.The component adaptation device detects this attribute configuration tabulation subsequently; Judge whether this configured list is legal; Promptly whether can be correct provide services on the Internet to the user; Can the constructed fuction of specifying member in member and the component base in the attribute configuration tabulation be carried out relatedly in the testing process, follow-up to processing data packets to optimize, concrete implementation method is a record member correspondence constructed fuction deposit position in the structure attribute item of information of attribute configuration tabulation; When the structure of adapter part during according to the attribute list handle packet; No longer need number the constructed fuction of seeking member in the component base, but obtain constructed fuction in the immediate subordinate property configured list, accelerate the packet processing procedure according to member numbering and member.If it is necessary in this attribute configuration tabulation member being arranged, realize that but mate member in the component information storehouse perhaps the attribute configuration tabulation of user's submission can't be accomplished the network service, then can return this attribute configuration tabulation of announcement user and need heavily fill out.For providing sufficient information to wrong user occurring; Deposit representative attribute configuration list information in the component information storehouse; The set of these configuration attribute tabulations is called as with reference to the attribute list storehouse; When the user need rewrite attribute configuration when tabulation, the attribute list that the component adaptation device has been filled in according to the user can provide the tabulation of the reference attribute configuration of basic network service with providing with reference to the attribute list storehouse.
After the attribute configuration tabulation detects and passes through; Promptly begin to send data; After the structure of component adaptation device partly receives packet, call the respective members constructed fuction according to the member constructed fuction shut sequence that generates in the testing process and revise and/or be added to the needed packet of this building blocks of function of completion packet header.Send from network adapter after accomplishing packet encapsulation work.
After node receives the packet grouping, the explanation part that can packet be given the component adaptation device.This part is read data packet packet header in regular turn, searches in the component information storehouse according to header packet information and mate member.Find coupling and call the explanation function of respective members behind the member; Completion is to packet packet header interpretation work, if this node is an intermediate node simultaneously, then packets need is transmitted; Can this component information be filled up in the attribute configuration tabulation, wait until when transmitting this packet and use.If there is not the coupling member, and this member is to be processed, and then this packet receives and handles failure, and the component adaptation device explains that part can return error message and give transmission source end.
If receiving node is a destination node, then packet can partly be sent to user application by the explanation of component adaptation device after accomplishing interpretation work, accomplishes the whole service procedure of packet.If receiving node is an intermediate node; Then packet can partly be sent to component adaptation device structure part by the explanation of component adaptation device after accomplishing interpretation work;, according to the attribute configuration list information of explaining that part generates packet is made amendment and/or added the work of packet packet header by the structure of component adaptation device part.For improving service quality, can suitably revise it according to content in the attribute list in the structure section processes process of component adaptation device, as making amendment to calling order; Add the structure attribute content, it is more about packet information etc. to make constructed fuction to obtain.
3. componentization protocol data packet format
