With the growing research, the Network on chip (NoC) architecture provides an opportunity for high scalability and freedom from the limitations of complex wiring. In this paper, a survey of five differential routing architecture comparisons and its results are analyzed. The five different architectures namely, low latency router by Look ahead adaptivity, NoC router with look ahead Bypass. Look ahead routing algorithm for 3D-NOC architecture, Wormhole switching architecture and Connection-oriented service in MANGO clockless NOC are the mentioned architectures. In accordance with the comparison results, the different types of Best effort routing and Guaranteed Services (GS) arbitrations are easily plugged into the router, which indicates a significant improvement in jitter which can be easily achieved.
