Soft Resource Reservation Method Using Fuzzy Theory for Multimedia Communication

这一年的研究是在去年取得的成果基础上进行的，是研究的继续。灵活、智能的多媒体网络体系结构的提出和设计可以概括为：(1)灵活的网络体系结构，其中多媒体通信的质量由用户级协议决定。(2)由用户请求发起的灵活的资源预留。(3)使用模糊逻辑的思想来表示用户请求的自然性的元级接口。(4)智能和优化地组合服务质量要求。因此，我们的建议是为了促进灵活的多媒体通信协议的设计，其中利用模糊逻辑的思想更好地表达用户的自然需求，并解释以优化分配所需的资源。可以通过对用户请求的这种解释来预留资源来服务最大数量的用户。我们进一步扩展了我们的工作，提出了路由算法，以便在网络上找到合适的路由，从而满足所有有意义的多媒体通信的多种服务质量要求。这种路由算法还注意使负载在整个网络中得到适当的分配，从而能够为最大数量的用户提供服务。这些研究的结果在几个国际会议上被提出，并在期刊上发表。随函附上一份部分。

The research during this year is based on the results obtained in during last year and is a continuation of the research. The research on the proposal and design of the flexible, intelligent multimedia network architecture can be summarised as follows :(1)Architecture of flexible network where the quality of multimedia communication is decided based on a user level protocol.(2)Flexible resource reservation initiated by the users' requests.(3)A metalevel interface using ideas from Fuzzy logic to represent the naturalness of users' request.(4)Composing the QoS requirements intelligently and optimally.Thus our proposal is to facilitate the design of flexible multimedia communication protocol where the users' natural requirements are expressed in a better way using ideas from Fuzzy logic, and interpreted to allocate optimally the required resources. It is possible to reserve resources to service maximum number of users by such interpretation of their request. We further extended our work proposing routing algorithm to find proper route on the network such that all the multiple QoS requirements for meaningful multimedia communication. This routing algorithms also takes care such that the load is properly distributed throughout the network, such that maximum number of users could be serviced.The results of these researches were presented in several international conferences as well as published injournal.
