Audio conferencing is an important aspect of Internet Telephony services. In this article, using a centralized conferencing architecture, we propose to employ application layer multicast for media distribution, by using "agents" responsible for the delivery of streaming media to end-clients, aiming at reducing the traffic in the network and the ser...

  • Jun 2015
In this paper, we have implemented the emulated multipath OpenFlow network with splitting and middle-box functionalities for investigating video buffering effects on packet delay and jitter performance for an RTP video streaming session. The mininet emulator is used to construct the multi-path OpenFlow network. The network consists of a video serve...
