Towards A New Generation Of Data-Aware Transport Networks
White Papers A major challenge, but not an insurmountable one thanks to the Alcatel 1850 Transport Service Switch. A decade's worth of service provider investment is under pressure, as packet-based traffic replaces traditional circuit-based traffic in response...

Multimedia Satellite Networks And TCP/IP Traffic Transport
White Papers Several performance issues need to be addressed before a transport layer protocol, like TCP can satisfactorily work over satellite ATM for large delay-bandwidth networks. In this paper, we review the proposed satellite systems and discuss...

Statistical Multiplexing In Data-Aware Transport Networks
White Papers Data traffic now represents the majority of traffic carried in transport networks. Guerin's equivalent bandwidth model takes into account the statistical multiplexing of aggregated variable traffic flows in an accurate and very simple way, enabling...

IP Telephony Design Guide
White Papers Therefore, it now makes sense to use the data network to transport voice instead of the voice network to transport data traffic. Understanding the underlying technology used to transport voice traffic is important in designing an IP telephony network.

Study Touts Metro Ethernet Cost Savings
News Ethernet equipment typically can cost anywhere from 40 to 50 percent less than traditional SONET/SDH (Synchronous Optical Network/Synchronous Digital Hierarchy) gear, which is often used to transport traffic in a metropolitan network.

ATM Trunking Using AAL2 For Narrowband Services
White Papers The ATM Trunking using AAL2 for Narrowband Services described in this specification fulfills an urgent market need for an efficient transport mechanism to carry voice, voice-band data, circuit mode data, frame mode data, and fax traffic.

Stackelberg Approach For Pricing Differentiated Services
White Papers The paper assumes that data transfer uses TCP congestion control protocol and that real-time traffic uses some TCP- friendly transport protocol that satisfies the same square-root formula for throughput.

Performance Modeling Of TCP/AQM With Generalized AIMD Under Intermediate Buffer Sizes
White Papers TCP is the dominant transport protocol to carry most of Internet data traffic, e.g.email, FTP, P2P. Each TCP source just iterates its own congestion control algorithm to respond to the congestion signal generated by AQM (Active Queue Management...

A Vision Of IP Multiservice Backbones And Proposed Implementation
White Papers This paper discusses how future data networks will use enhanced IP as the Layer 3 technology, preferably combined with MPLS capabilities for traffic engineering.At present, Internet protocol (IP) [1] networks are built to transport data without...

Performance Evaluation Of UMTS For Mobile Internet Access
White Papers These Internet applications rely on two common protocols, namely, Transmission Control Protocol and the Internet Protocol (TCP/IP), to reliably transport data across heterogeneous networks. The UMTS has been designed to address specifically the...
