Abstract : The need for the high computational power has led to the birth of the many-core architecture and its accompanying interconnect system Network on Chip (NOC). Communication between the routers of the cores is increased due to cache misses in the core. The congestion in the network has led to an increase in the latency and decrease in the throughput even with many cores for computation. The injection rate in the network is what determines the capacity of network load that it can withstand. The paper discusses the Threshold injection rate (TIR) which serves as a parameter to determine the upper bound of the network. And also, various parameters that affect the Threshold injection rate are discussed. The parameters considered are the number of virtual channels (VC), traffic pattern, size of the network, packet size, flit size etc.
