The core components of a network play vital role in its enhancement. For launching and providing Internet applications and services, vendors have come up with a variety of different technology based network cores and other components of Internet backbone. Among all the challenges for an efficient network core, traffic-routing is the most important. Both the routing algorithms and the router-technology are supposed to perform efficiently. The authors found that there are a number of technologies that offer packet routing service of which IP, ATM and MPLS are prominent.
