Host Vc Module Service Network Architecture Design And Implementation,

This paper states the virtual circuit architecture prototype host based on Service Unit Network Architecture(SUNA).The SUNA is a brand new network architecture which is quite different from the current layered network architecture .It can solve the deficiency in current layered network architectures caused by multi-layer functional duplication and complicated processing and is easy to design and implement and has greater flexibility.This paper analyses the traits and node models of the SUNA and the services it provides.It also state the design of the prototype host including the definition of the modules and the functions of each modules.This prototype host can provides two kinds of data stream services.One is reliable data stream service,we use simplified Sliding Window Protocol to ensure the reliability. And the other is unreliable data stream service.This data stream transmission based on the virtual circuit architecture.My main task is to accomplish the virtual circuit management module.So,this paper focus on the deep research of this module.The virtual circuit management module is consists of three sub-modules which are virtual-circuit-create sub-module,virtual-circuit-hold sub-module,virtual-circuit-free sub-module.We create a virtual circuit between each other before they begin to communicate,then we hold this virtual circuit during the communication process,finally, free this virtual circuit after finish the communication.I coded this program with C under Linux kernel and use the KGDB to debug the module. The results of test,combining both prototype host and prototype router, demonstrate that this module can meet the requirement the uerer demands and performance better than the layered network architecture. This results also can prove that all the modules I have designed are correct.This paper comes from the XXXX creative fund.Because no one has done this prototype host before,we have met some difficulties.We utilized some advanced technology,discussed with our professors and teamates and finally...
