This paper proposes an efficient multicast-like transfer mechanism for on-demand video streaming. The rapid growth of Internet video services such as YouTube has caused increased traffic and network congestion. Network-driven multicast-like transfer is a desirable protocol to suppress unicast-based video traffic efficiently using multicastlike packet forwarding. To analyze the applicability of this mechanism to on-demand video delivery services, this paper first confirms the packet sameness when multiple users virtually simultaneously watch the same video contents. Based on the results from packet-based inspection, we then propose the video packet synchronizer and the video packet buffers and implement them for one of the conventional multicast-like transfer protocols. The experimental results show that the proposed network-driven multicast-like transfer scheme can reduce up to 25 percent of video traffic.
