Abstract

Traffic demand for real-time services as well as non real-time services has recently been increasing, due to the rapid improvement in transmission bit-rate within communication networks. In the future ubiquitous network society, in addition to traffic demand for user-to-user real-time communications services, traffic of real-time applications is set to explode due to new communications traffic for machine-to-machine communications. This paper proposes “ultra low-latency mobile networks,” where the target value for unidirectional end-to-end latency per IP packet is 10 ms, in order to establish a new communications infrastructure capable of providing next-generation real-time services. This paper introduces a model of such ultra low-latency mobile networks and the results of a feasibility study are also presented. The simulation study shows the potential to realize a mobile network with ultra low-latency of less than 10 ms for IP packets and a low IP packet error rate of  < 0.1% through simulations. A test-bed developed to measure actual latency is also introduced in this paper as well as measurement results using this test-bed. The measurement results also confirm the possibility indicated by the simulation studies.
