The present invention, based on network simulation operation platform, simulates various operating system and service leak.With a physics master
On the basis of machine realizes live network Dynamic simulation, the small scale network that multiple stage physical host emulates is connected into fairly large
Network, and be each network equipments configuration equipment feature.For general user, platform as a kind of network struction instrument,
The display unit observation that platform provides flows through the flow of platform and the network equipment.For developer, platform provides development interface,
Exploitation meets the functional device of needs.
Whole platform is divided into four layers: key-course, mechanical floor, program layer and communication layers.The function of each layer is introduced respectively
As follows:
(1) control to functional device during key-course is responsible for platform and the initialization of functional device and running, and provide
User interface.Including three subelements: device control cell, network configuration element and user interface section.Device control cell
It is responsible for the concrete network equipment is configured, including setting operation system, file system and open port；Network configuration list

The various network services run on virtual network device.Signal procedure refers to the application software with network communicating function, by joining
Put, using these application softwaries as on the network equipment application program run so that the network equipment in an active manner with other
Main frame communicates.File interface is used for the file system of fictitious host computer, provides file operation service to thread and reflects institute's mould
The feature of the operating system intended, including tissue and operation two parts of file of file.
(4) communication layers is responsible for the communication work of the network equipment, including protocol characteristic storehouse, ICP/IP protocol stack, network interface
With display interface.Protocol characteristic storehouse comprises the protocol stack characteristic information of various operating system, for the behaviour of virtual network device
Make system loads protocol stack feature, identify the operating system of remote access host.ICP/IP protocol stack is for managing in platform
All connections, it is ensured that being correctly completed of equipment communication.The agreement of platform processes has link layer protocol, ARP, IP, TCP, UDP association
View, application layer protocol is then given application program and is realized.This subelement achieves the encapsulation to TCP/IP protocol suite, provides a user with
Protocol data package interface at all levels.These interfaces can be used for encapsulation needs the message of transmission, it is also possible to utilize this
A little interfaces extract field interested in message and are analyzed.Network interface is used for being linked in live network platform, and
During platform runs, network data is caught.Platform catch data have both of which, be respectively user model and
Kernel mode, can only operate in the transport layer of ICP/IP protocol under user model, it is impossible to directly data intercept link-layer frame and net
Network layers message, and kernel mode can obtain the frame of link layer, it is achieved intermediate drivers level catches, including message seizure, message

Each layer protocol uses modularized design, and every kind of agreement has the protocol header of oneself to define, and provides protocol header
Analyze and encapsulation operation.For analyzing operation, when platform receives Frame, the every layer data comprised is located accordingly
Reason, by repeatedly solving the operation that frame unpacks, checks each tab character in header, determines the upper strata association receiving data
View, finally consigns to application program by the application layer data in frame.For encapsulation operation, when application layer data needs to pass through platform
During transmission, needing to be packaged data by protocol stack, encapsulation will increase frame head letter on the basis of receiving data every time
Breath, eventually forms the Frame that can transmit over ethernet.
After platform captures Frame by network interface, according to the type field of frame judge be adress analysis message or
IP message, if adress analysis message is then directly responded by platform, abandons the adress analysis message that the machine sends, otherwise
Transferring to virtual network device to process, the message processed is sent by platform.
The entrance entering virtual network at message arranges input router, in order to be given at input router by message
Reason, defines the cache pool between platform and input router, and the message processed is sent into cache pool by platform, and message is at cache pool
In store in the way of dynamic link table, if cache pool is full, abandon new bag.Virtual network device processes the flow process tool of message
Body includes:
Input router reads message from cache pool, and first message carries out pretreatment, checks length and the verification of bag
Code, then analysis purpose address and data from message, send the data to destination host finally according to routing table.Host process
After completing, before message is sent to gateway route, in addition it is also necessary to be packaged, load predetermined feature so that it is meet configuration
Operating system features, last message is stored in cache pool through input router.
The network equipment may used when building the network of emulation has main frame, router, fire wall, hub etc..This
Router and the main frame of emulation are illustrated by inventive embodiment.Virtual router is that network environment is carried out with fictitious host computer
The bridge of communication, therefore virtual router not only has data and transfers function, provides simultaneously and carries out connecing of data interaction with platform
Mouthful.Router is divided into four unit, respectively NIU, data processing unit, route planning unit and data turn
Send unit.Function and the design realization of each unit are described below:
The function of NIU is to receive and send message.From the angle of router access network, router is divided into
Two classes: input router and ordinary router.Input router is the road being joined directly together with true main frame place network in logic
By device, ordinary router is directly or indirectly connected with input router.Input router enters virtual network as data and runs
Entrance, need the data from platform are processed, and transfer to destination host；Ingress router is also required to empty simultaneously
The message that plan main frame is sent out is packaged into Frame and gives platform.
Data processing unit is responsible for data detection, error control, ip packet filter, packet loss and Delay computing.Data detection bag
Include inspection IP packet header successively verification and, whether be error message and whether be multicast message；Error control includes processing
The message of mistake occurs, sends message to source host and report reason of makeing mistakes, it is achieved that two kinds of messages, are query message and mistake respectively
Difference report message；Ip packet filter realizes the filtration to IP bag, is directed to broadcast packet；Message often through a router, all can
Producing corresponding delay, router is before transferring, it should calculate delay, and link also has certain packet loss, packet loss simultaneously
This function can be completed with Delay computing.
Route planning unit utilizes IP bag to realize route planning algorithm, thus realizes route planning.Can also be responsible for satisfying the need
By maintenance and the renewal of table.
Transfer unit, according to purpose IP address search virtual routing tables, determines to which virtual router to send.

Network.Assume the true main frame that B is platform place, access Internet, V by router A1-VnFor the n of emulation on true main frame
Platform main frame.If within the scope of visitor is positioned at the LAN at fictitious host computer place.When visitor attempts and fictitious host computer ViCommunication
Time, wherein 1≤i≤n, find fictitious host computer ViBe positioned at the same network segment with it, then it can first look for the adress analysis of oneself
Caching.If there being fictitious host computer V in Huan CuniMAC Address, then message directly transmits away；Without fictitious host computer Vi's
MAC Address, then send adress analysis bag and ask fictitious host computer ViMAC Address, obtain fictitious host computer ViMAC Address after again
Send data.As fictitious host computer ViWhen receiving, by the Internet, the message that a remote access person sends, router A connects
While receiving message and begin attempt to be sent out this bag.Router is retrieved by routing table, and determines this ViBag
Where it is sent to.If route points to Vi, then this router then can abandon current message；The message that router A will receive
It is transferred to other router；If there is V in the LAN at router placei, ViThen can receive the bag transmitted by router A.Will
VIData stream transmitting to the process of true host B use one of following two mode: true host B is by sending fictitious host computer Vi
Route entrance set.In this way, message then can be transferred on fictitious host computer then directly transmit by router
To true main frame.In the situation of the router without special outfit, router can use the instruction of Address Resolution Protocol to inquire about
The hardware address of fictitious host computer.But being because the fictitious host computer not having to respond, the query statement analyzing agreement will not obtain
To response.Now respond above-mentioned query statement with the hardware address of true main frame.Allow router by ViMessage transmit the most pure virginity
Real main frame.Under increasingly complex special network environment, or the address space that a section idle is connected by routed encapsulation
To true main frame.
