Embodiment
Member is divided into hardware component and software component two classes, and wherein hardware component depends on concrete hardware item, and software component does not generally rely on concrete hardware item, and member described herein refers to hardware component.Existing hardware item comprises reconfigurable hardware body and restructural hardware item not.Wherein, the restructural hardware item be not suitable for user's particular demands, so the reconfigurable hardware body is not used in more and more in the independently developed environment of user owing to customizing functions.The reconfigurable hardware body is made of programmable logic chip, the programmable logic chip of network communication field mainly contain network processing unit (Network Processor, NP) and field programmable gate array (Field Programmable Gate Array, FPGA).The inventor finds following situation in carrying out the invention process:
1, these two kinds of chips still are that programming mode is all inequality from production technology;
2, the NP and the FPGA developing instrument of different manufacturers production are also all inequality, for example the programmed method and the configuration file format of the FPGA manufacturer of two kinds of main flows (Altera and Xilinx) employing are just inconsistent, and the architecture of the NP of different manufacturers, programmed environment and programming language all are inequality.
Apparatus for network node by each manufacturer production seals for user and other manufacturers, that is to say, except manufacturer, the concrete condition of the bottom formation of this network equipment as hardware component all can't be understood by user and other producers.Thereby can't make amendment, expand or upgrade, this work can only just can be finished by former producer, that is to say, the user can only select the fixedly product of manufacturer, and this product often has multiple function, does not need and many functions are the users at all, has caused the waste of resource.And the internal interface of existing equipment generally is covert, and standard also is producer oneself definition, and the assembly of different producers is difficult to collocation and works together.For example: for network node, the high-end route switching node on the market all is made up of interface module, table look-up forwarding module and Switching Module.But the product inside of each producer is sealed, and the interface between each module also is each producer oneself definition, and the user can not select the disparate modules composition efficient maximum of different manufacturers, the solution that cost is minimum according to self needs.
In addition, above-mentioned phenomenon makes the user to make amendment to hardware component at the network environment of equipment and concrete demand, and causes in the different network environment of correspondence, needs to be equipped with different equipment, the waste that has brought hardware resource.
In order to address the above problem, the invention provides a solution, its basic thought is: be provided with and reconfigurable hardware body corresponding driving function, at the position of each member in equipment the abstract adaptation function is set, and different hardware unit member is set, thereby can download the hardware unit member of different performance according to the difference of operate outside environment according to the operate outside environment.In addition, the form of defined order information promptly meets unified control information consensus standard, exchanges data carrying standard.For the user, when generating member, it need not to consider the difference of the interface and the driving function of each reconfigurable hardware body, and only need know position and the function of member in the network equipment.
