Voice over IP (VoIP) Implementation Guide for Network Performance Management 2006-08-22 11:57:59 NetScout Systems

The long-hyped convergence of voice and data onto a single network is finally becoming reality. Major industry magazines and analysts are now discussing the explosion of VoIP deployments, and corporate rollouts have commenced in order to take advantage of the operational efficiencies and competitive advantages that are facilitated through VoIP's advanced communication services.

However, when convergence occurs on your network, will the infrastructure be ready to handle this added burden? Almost universally, industry analysts talk about incomplete and delayed VoIP implementations caused by poor pre-deployment analysis, planning and lack of wellintegrated management tools that address both networked voice and data applications. The risks are not only the investments made in the VoIP equipment and upgraded infrastructure, but also in the potential impact on organizational productivity when a voice initiative has a negative effect on existing networked business services. The reputation of the IT organization can hinge on the success or failure of a VoIP implementation.

The solution to mitigate these risks is a lifecycle approach to VoIP deployment: assessment, planning, impact analysis, and ongoing management. Although completing each of these steps may seem, at times, overwhelming and complex, engaging a network and application performance management solution, especially one that will view VoIP in context with all other application traffic on the network, will increase the potential for a successful project.

This white paper describes how the nGenius� Performance Management System can help in completing a comprehensive analysis, developing a thorough plan, and assessing the impact of your VoIP implementation. A thorough investigation of each step of the lifecycle process increases the probability of a successful rollout, and ultimately achieves optimized performance of both business and voice applications across the enterprise network.

On Designing Incentive-Compatible Routing and Forwarding Protocols in Wireless Ad-�Hoc Networks - An Integrated Approach Using Game Theoretical and Cryptographic Techniques 2006-12-13 01:00:24 Association for Computing Machinery

In many applications, wireless ad-hoc networks are formed by devices belonging to independent users. Therefore, a challenging problem is how to provide incentives to stimulate cooperation. This paper presents a study of ad-hoc games - the routing and packet forwarding games in wireless ad-hoc networks. The paper investigates both routing and forwarding. The paper uncovers an impossibility result - there does not exist a protocol such that following the protocol to always forward others' traffic is a dominant action.

Multicast on MCI Private IP 2005-10-25 03:00:02

Most customer equipment supports IP multicast, but, because of unfamiliarity with this protocol on the part of IT managers, few Private IP customers take advantage of this efficient way of distributing a wide variety of data and multimedia applications. The information in this paper illustrates the basics of multicast along with a discussion of multicast across the Private IP network.

Avaya SIP Enablement Services (SIP) 3.0 / Ports and Protocols 2005-12-01 01:00:02

This white paper covers the network ports and protocols used by the Avaya Converged Communications Server 3.0 (SES), Avaya SIP User Agents (includes Avaya IP Softphone R5.x, Avaya SIP Softphone, and Avaya SIP Phones), and other Avaya SIP entities. This includes the following - SES and other SES's, SES and Avaya Communication Manager (S8xx0), SES and Network Administrator/Other, SES and Avaya IP Softphone R5.x w/IM and Presence, SES and Avaya SIP Softphone R2, SES and Avaya SIP Phones (4602, 4610, 4620SW, 4621), SES in a redundant configuration.

Characterizing Session Initiation Protocol (SIP) Network Performance and Reliability 2006-11-29 01:00:19 Springer Science+Business Media

The Session Initiation Protocol (SIP) has emerged as the preferred Internet telephony signaling protocol for communications networks. In this capacity, it becomes increasingly essential to characterize both the performance and the reliability of the signaling entities utilizing the protocol. This paper provides an analytical look at the performance of a SIP network as well as a reliability model of SIP servers.

Delivering Unique Services that Meet Customer Needs 2005-10-20 09:49:12

The telecommunications industry is rapidly re-inventing itself to meet its changing and expanding role in the business world. With the advent of cellular, WiFi, WiMax and increasingly powerful and portable devices, the demand for unique services to fit a customer's business model is growing each day. This paper discusses the telecommunications industry's move towards a standard architecture known as the IP Multimedia Subsystem (IMS), the benefits of an IMS infrastructure to service providers and their customers, the complexity of delivering a silo-less service architecture, and an approach to simplifying the delivery.
