    This article presents a trace-driven analysis of IP over ATM services from an ATM-centric standpoint. We provide a characterization of TCP flows as VBR streams with burstiness (MBS) and throughput (SCR). On the other hand, a macroscopic analysis comprising percentage of flows and bytes per service, TCP average transaction duration, and bytes transferred both ways is also presented. The ATM link un...

    After the IEEE 802.11 standardization group established the first wireless LAN, several efforts were started to increase data rates and also to use other bands. This article describes the new wireless LAN standards developed by IEEE 802.11, ETSI BRAN, and MMAC. The new standards are targeting data rates up to 11 Mb/s in the 2.4 GHz band and up to 54 Mb/s in the 5 GHz band View full abstract»

    In multiprotocol label switching (MPLS) networks, data packets are forwarded through label-switched paths (LSPs) which are set up using a label distribution protocol. Since any label distribution protocol makes use of information obtained from the layer 3 routing protocol, and the routing protocol may not be loop-free, there is a possibility of an LSP forming a loop. This article focuses on MPLS l... View full abstract»

    MPLS (multiprotocol label switching) is a convergence of various implementations of IP switching using ATM-like “label swapping” to speed up packet forwarding without changes to existing IP routing protocols. An important practical issue is the capability to recover quickly from faults. We examine distributed methods for fast fault recovery using modified label distribution protocol me...

    The use of connection-oriented (CO) networks for the transport of IP traffic is seen to have value to both users and service providers. Given the expectation that most endpoint-generated traffic will be in the form of connectionless (CL) IP datagrams, we address the problem of how to internetwork a CL (IP) network with a CO network. CO networks can be packet-switched or circuit-switched. Examples ... View full abstract»

    This article discusses the architectural aspects of MPLS which enable it to address IP traffic management. Specific MPLS architectural features discussed are separation of control and forwarding, the label stack, multiple control planes, and integrated IP and constraint-based routing. The article then discusses how these features address network scalability, simplify network service integration, o... View full abstract»

    The rapid increase of Internet traffic is pushing the deployment of WDM technology in the next-generation high-speed Internet backbone. Routers in the backbone could still be the potential bottleneck. In this article we consider some design issues of high-throughput optical routers which combine the advantages of WDM with the new optical switching technology. We first introduce a proposed Internet... View full abstract»

    The explosive growth of the Internet over the last few years has made the IP protocol suite the most predominant networking technology. Furthermore, the convergence of voice and data communications over a single network infrastructure is expected to happen over IP-based networks. Traditional IP-networks offer little predictability of service, which is often unacceptable for applications such as te... View full abstract»

    In the transmission process of a variable bit rate video signal over an ATM network, cells are inevitably exposed to delays and losses due to the statistical multiplexing used in these networks. These phenomena affect the quality of the video signal, and without adequate measures to control the propagation of impairments, the quality of service may fall below acceptable levels. We introduce a set ... View full abstract»

    In principle, the interaction of the resource reservation protocol (RSVP) and ATM should allow the IP level to benefit from some features of the ATM layer. The most interesting one is the native support of end-to-end quality of service provided by ATM. On the other hand, there are issues that must be clarified to define correct interworking: for example, the possible overlapping between the mechan... View full abstract»
