At present, the support of processor to Intel Virtualization Technology of X86-based is fairly perfect, and the VMware software selected by the present invention is also developed based on X86-based, so select the server of X86-based as hardware platform, not only can utilize the high-performance of processor-server, and decrease the expense of instruction transformation between different framework.
S2: install software virtual machine in Windows operating system, proceed to S3.
Traditional virtual technology uses software virtual machine and assembly thereof to carry out the virtual of router, its realization depends on the software virtual machine that other manufacturers provide, and the present invention uses software virtual machine only as the carrying tool of virtualized environment, can adjust as required, use flexibly, this is also the place that the present invention is different from traditional virtual technology.
Software virtual machine described in S2 can be VMware software, Virtualbox software etc.The present embodiment selects VMware software, then S2 specifically comprises the following steps: in Windows operating system, install VMware software, and installs tornadoforPentium software, Ramdisk software, winimage software and DTLite software.
Wherein, tornadoforPentium software is the development environment software of VxWorks operating system; Ramdisk software is used for setting up virtual floppy disk, and auxiliary VxWorks system generates startup file bootroom; It is floppy disk mirror image (path of this floppy disk mirror image is arranged in VMware software) that winimage software is used for bootrom file translations, and starts VxWorks system; DTlite software is for creating virtual drive to install tornadoforPentium software.
S3: utilize software virtual machine to create virtual machine; According to conventional routers code framework, by carrying out the mode of cutting to existing VxWorks operating system, development of virtual embedded OS; In the virtual machine created, run developed virtual embedded OS, proceed to S4.
In order to ensure reliability when running virtual router, when utilizing software virtual machine (VMware) to create virtual machine described in S3, the virutal machine memory of establishment should be greater than router code and run required maximum memory.
S4: router code is run in developed virtual embedded OS; After the CPU generation goal systems of server, carry out internal debugging to the ruuning situation of whole router code, determine that router code runs smooth and easy, the now work of virtual router completes substantially, proceeds to S5.Wherein, the content of debugging comprises BSP (boardsupportpackage, board suppot package) debugging, SDK (SoftwareDevelopmentKit, SDK) debugging, drive debugging, routing protocol stack debugging, system integration debugging and webmaster debugging etc.
S5: external testing is carried out to the virtual router debugged; After having tested, contrast conventional routers and the test result of virtual router, the performance of analyzing virtual router, from BSP, driving, protocol stack, router, integrated and software layer, carries out horizontal and vertical optimization to it, terminates.
When utilizing said method to carry out realizing of virtual router, because router code has carried out Reseal to protocol stack and driving layer relevant interface parameter, therefore, exploitation and when compiling virtual embedded OS mirror image, need the code details according to router, virtual embedded OS is customized again.Development of virtual embedded OS, the process of a cutting system in fact, for VxWorks system used in the present invention, mainly under cutting tornado catalogue, drive and the partial code of ICP/IP protocol stack about Microsoft Loopback Adapter, the normal work of these some effects Microsoft Loopback Adapters.
