Layer 3 Switching Alternatives

چکیده
Cut-Through switching techniques, and Application Spec@ic Integrated Circuit (ASIC)-based wire-speed routing both attempt to improve network pe~ormance whenever possible. While switching advocates prefer the, “Route once, switch thereafter” approach, ASIC-based routing vendors believe the “Route wherever you wish” approach is the prevailing long-term solution. Both attempt to eliminate the cost premium and the performance penal~ normally associated with Internet Protocol (1P) routing. In this paper, I discuss several competing cut-through switching approaches, the emergence of ASIC-based routing implementations, and explore the associated advantages and disadvantages of each approach.

Performance Analysis of AAL2 switching/multiplexing in the Iub interface in UMTS Network
User-perceived application-level performance is very important in the adoption and success of UMTS (Universal Mobile Telecommunication System) services and infrastructure. To predict this performance, a detailed end-to-end UMTS network performance simulator was developed. The simulator allows the modeling of application traffic characteristics, network architecture, network elements, and protoc...
متن کاملRadio Frequency-micro Electromechanical System Switch with High Speed and Low Actuated Voltage
This paper presents a novel RF MEMS (Micro Electromechanical System) fixed-fixed switch for very fast switching. Using the obtained equations, the switching time depends on the stiffness and effective mass of the switch beam so that the switching time will be decreased by higher stiffness (spring constant) and lower effective mass. In new design, the suspension bridge is a three-layer beam so t...
متن کاملStabilizing Intelligent Route Control: Randomized Path Monitoring, Randomized Path Switching or History-Aware Path Switching?
Multihoming Intelligent Route Control (IRC) plays a significant role in improving the performance of Internet accesses. However, in a competitive environment, IRC systems may introduce persistent route oscillations, causing significant performance degradation. In this study, we investigate three design alternatives to cope with this issue: Randomized Path Monitoring, Randomized Path Switching a...
متن کاملDynamics of Portal Email Switching: Attractive Alternatives and Switching Costs
Internet portals have been using the email service to attract new members and to retain existing customers. This research aims to enhance the understanding of mechanisms associated to users' intention for email switching (IES). We have employed customer's satisfaction on email service, attractive alternatives, and switching cost to explain the dynamics of IES. Customer's satisfaction is measure...
متن کاملFlow aggregated, traffic driven label mapping in label-switching networks
Label-switching technology enables high performance and flexible layer-3 packet forwarding based on the fixed-length label information that is mapped to the layer-3 packet stream. A label-switching router (LSR) forwards layer-3 packets based on their layer-3 address information or their label information that is mapped to the layer-3 address information. Two label-mapping policies have been pro...
