THE ROLE OF OTN SWITCHING IN 100G & BEYOND TRANSPORT NETWORKS Managing Bandwidth for Long Haul and Metro Network Evolution
ثبت نشده
چکیده
cloud, and data center interconnect, service providers worldwide have been migrating from 10G to 100G and beyond. Already begun in long haul networks, this migration is now proliferating in metro networks. In addition, many service providers are adopting OTN switching as a more effective technology for grooming lower speed clients onto high speed line interfaces and efficiently managing bandwidth. This white paper examines the benefits of OTN switching together with the added value of next-generation universal switches that combine OTN, packet, and SONET/SDH switching. 100G(+) ADMs are also discussed as a complementary option for smaller sites. Network scenario examples illustrate when a transponder and muxponder, OTN switch, or 100G(+) ADM approach may offer the greatest advantages.

متن کاملA Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
