The rapid pace of technology introduction in the network infrastructure and services offered on this infrastructure are creating new challenges for telecommunication product and network planners. In particular, a multitude of choices, the ...

There has been an explosion in the number of wireless subscribers. A number of air interface technologies, such as GSM, TDMA and CDMA, are available to wireless service providers for offering wireless services. In addition, a variety of networking ...

This article presents a discrete-event simulator, called QUARTS-II, that can be used for the design and analysis of routing protocols for ATM networks. This simulator shares many high-level features of the ATM Forum's P-NNI routing protocol; topology-...

ATM offers the capability of consolidating multiple services onto a common backbone network, thereby reducing network management complexity, improving utilization, and lowering cost. As ATM networks grow, a virtual path connection (VPC) network core is ...

Transport networks are facing new challenges and opportunities because of the explosive growth of data traffic. Besides having to meet the ever-increasing bandwidth demand, transport networks need to provide new functionalities for the support of data ...

This article discusses the design of a scalable high-performance multiservice network based on programmable transport. A meshed network with dynamically adjustable link capacities and nodes which provide data packing into “containers” for ...

Network design is a compromise between two conflicting requirements: high network efficiency and high quality of service (QoS). High efficiency suggests full sharing of network resources. However, in a multiclass network, QoS differentiation among ...

This article presents results from research that included the modeling of various self-healing structures in order to compute the service availability between any two nodes within a given survivable network. In particular, terminal-pair availabilities ...

A “reserved bandwidth” service is described as a quality of service enhancement in the vBNS. Design of this service is based on the characteristics of vBNS user traffic and the state of the art of commercially available technology. An ...

IP over SONET technology is being deployed today in IP backbone networks to provide efficient, cost-effective, high-speed transport between fast routers. The authors present an overview of the architectural considerations in the deployment of IP over ...

Future routers must not only forward packets at high speeds, but also deal with nontrivial issues such as scheduling support for differential services, heterogeneous link technologies, and backward compatibility with a wide range of packet formats and ...

With the transformation of the Internet into a commercial infrastructure, the ability to provide differentiated services to users with widely varying requirements is rapidly becoming as important as meeting the massive increases in bandwidth demand. ...

Multiprotocol label switching (MPLS) is rapidly emerging as an Internet Engineering Task Force (IETF) standard intended to enhance the speed, scalability, and service provisioning capabilities in the Internet. MPLS uses the technique of packet ...

The monitoring purpose of the broadcast transmission system is to provide a means of determining how the transmission system is performing and where a fault or abnormal condition exists in the transmission chain. This article presents the monitoring ...
