Robust Load Balancing in Wireless Networks: This paper studies load balancing in a wireless network. It presents a robust approach that enables cross-layer optimization of both transmission schedule and routing without the knowledge of traffic matrix. This approach is shown to clearly outperform an approach where only the MAC layer is optimized. Further, the paper shows...; Tags: Optimization, Network, Load Balancing, Wireless Network, IST Press, Traffic Matrix, Wi-Fi, Network Technology, Wireless, Networking; White papers 2007-12-07
Transport Layer Identification of P2P Traffic: Indeed, access to user payload is often rendered impossible by one of these factors, inhibiting trustworthy estimation of P2P traffic growth and dynamics. This paper develops a systematic methodology to identify P2P flows at the transport layer, i.e., based on connection patterns of P2P networks, and without relying on packet...; Tags: P2P, Peer To Peer (P2P), Internet; White papers 2004-10-27

Multilayer Traffic Engineering in IP-Over-Optical Networks: Recent advances in optical networking technology have moved the state-of-the-art from manually installed fiber connections to fully automatic switched lightpaths. IP-over-Optical networks carry Internet traffic between IP routers, using lightpaths optical connections with multi Gbit/s bandwidth as transport method. Multilayer Traffic Engineering MTE in an IP-over-Optical network allows to leverage...; Tags: Optical Networking, Router, IP, Network Technology, Networking, Routers & Switches; White papers 2005-11-30
Any Transport Over MPLS: Any Transport over MPLS AToM transports Layer 2 packets over a Multiprotocol Label Switching MPLS backbone. AToM enables service providers to connect customer sites with existing data link layer (Layer 2) networks, by using a single, integrated, packet-based network infrastructure - a Cisco MPLS network. Instead of separate networks with...; Tags: Layer 2, AToM, MPLS, Network, Network Technology, Networking; White papers 2007-11-13
Real-Time TCP/IP Analysis With Common Hardware: Traffic measurement represents an indispensable and valuable tool for the analysis of telecommunication networks. Moreover, it is desirable for traffic measurement and analysis to be both continuous and persistent, since only these joint requirements allow tracking important changes on the traffic pattern.
