Abstract(in English) | In 5th Generation mobile communication, it is considered that Mobile Front Haul (MFH) network is integrated to Layer 2 network because of network efficiency. However, in such a network, MFH traffic may be influenced by other traffic in point of delay. As MFH traffic is delay-sensitive, IEEE802.1-Time Sensitive Networking (TSN) is paid attention because it may achieve low latency communication in packet network. In this paper, we focus on IEEE802.1Qbv (Time Aware Shaper : TAS) which is one of the queueing architecture of TSN. We have proposed the autonomous TAS method called intelligent TAS (iTAS) which could solve the operational problem previously, and have verified the principle of iTAS by using software prototype. In this paper, we implement a part of iTAS function to FPGA and achieve 1000 times more granularityimprovement. This result shows that our method can be applied to actual MFH environment. |
