This is because the conventional IP network has been designed from a location-oriented viewpoint, while users generally have a content-oriented viewpoint. That is, users are...
Streaming services provided by data centers (DCs) have become increasingly popular. The quality of streaming services greatly depends on network conditions, though, such as available bandwidth and delay time characteristics. To realize high quality stream- ing services, selecting an appropriate access network among available ones is necessary. However, in wireless LANs, a station (STA) simply selects...
Packet losses significantly degrade TCP performance in high latency networks. To improve TCP performance in such networks, we proposed two methods to suppress the return of duplicate ACKs and to control minimum redundancy because FEC technology cannot work effectively when simply applied to TCP operation. Simulation evaluations show that the proposed methods enable higher throughput than the conventional...
