Community based routing scheme for future Internet considering PLM systems

Internet plays an increasingly significant role in our modern life style for our society, educational institution, engineering systems and industrial applications. It serves billions of users worldwide every day by carrying an extensive range of traffic from sources to desired destinations. Along with these advances, inter-domain routing nodes of internet are facing challenging issues like scalability. Path vector routing scheme is not sufficient to cope with this issues for building future internet. There are many different Advance Routing schemes available in the literature for solving the problem. Thorup Zwick routing scheme (TZ scheme) is one of the promising Compact Routing scheme, offering many benefits such as guaranteeing sub-linear state growth with the size of the network by introducing cluster nodes, landmark routing and incurring path stretch. However, the extra burden of routing table size in landmark nodes is an important issue which can generate scalability issues for landmark nodes. This paper tries to solve the scalability problem of internet by making modification in Thorup Zwick (TZ) scheme. we introduce a new concept named community in the topology of internet, re-define cluster nodes and replace landmark nodes with proposed community nodes in the network. The proposal organizes internet in an efficient way by defining new set of rules for inter-domain nodes and reduce routing table size in a prominent amount. The proposal provides an organized, simpler and effective routing scheme. A discrete event simulation study is used to verify the benefits of new scheme. Our simulation results show that the proposed scheme is capable to cope scalability issues of inter-domain nodes, handle generated traffic considering PLM systems and build an efficient future Internet.
