whitepaper TANDBERG and Packet Loss2009-06-17 Tandberg
  This paper is intended to describe the packet loss robustness features available with TANDBERG's products. These features include: Intelligent Packet Loss RecoveryTF (IPLRTF), Downspeeding, Quality of Service (QoS). The above mentioned features are all available on the following products: TANDBERG MCU 16+16 / 8+8, TANDBERG GW, TANDBERG 8000, TANDBERG 7000, TANDBERG 6000, TANDBERG 2500, TANDBERG 1000, TANDBERG 880, TANDBERG 800, TANDBERG 550, TANDBERG 500. The IPLR feature is not intended to replace Quality of Service (QoS) techniques which may be employed on IP networks to reserve bandwidth or set precedence on video traffic. However, in the rare event that QoS techniques fail, IPLR is designed to overcome transient packet loss situations and reduce the impact these losses may have on the current video traffic. To fully understand what IPLR offers, an understanding of QoS and video compression are recommended. This paper briefly describes each before describing the details of TANDBERG's IPLR.

whitepaper Managing an IP Telephony Deployment in a Small to Mid Size Business2009-01-01 Callahan Marketing & Advertising
  IP telephony is the preferred method for implementing a communications system in today's business environment but getting there requires a lot of planning to make it happen. From building out the network, to supporting the system, to training the end user there are many pieces to the puzzle. This paper will go through the steps of planning out an IP telephony project for a small to medium size business. The correct order is essential as is the time management and making sure each piece is completed and ready for the next step. Putting together the proper team and leaders is also paramount to success. Who communicates with management? These along with many others must be examined.

whitepaper Achieving Business Agility with Application Grid2008-12-01 Oracle
  Companies are learning how to run their data centers more efficiently using less hardware, less software and less IT resources. These companies are turning to a new concept called application grid, an infrastructure layer beneath the application layer that pools and dynamically provisions the resources on which those applications run. Application grid brings the same type of efficiency, scalability, and quality of service to the application layer that database clusters brings to the database layer. With an application grid you get greater efficiency, exceptional agility, and superior quality of service. Download this free white paper now.

whitepaper Cognitive Packet Networks: QoS and Performance2008-01-01 University of Central Florida
  Reliability, security, scalability and QoS (Quality-of-Service) have become key issues as one envision the future Internet. This paper presents the "Cognitive Packet Network (CPN)" architecture in which intelligent peer-to-peer routing is carried out with the help of "Smart packets" based on best-effort QoS goals. Since packetized voice has stringent QoS requirements, the paper then discusses the choice of a "Goal" and "Reward" function for this application and present experiments conducted for "Voice over CPN". Its performance is detailed via several measurements, and the resulting QoS is compared with that of the IP routing protocol under identical conditions showing the gain resulting from the use of CPN.

whitepaper Capacity Management and Optimization of Voice Traffic2007-11-01 Cisco Systems
  Nowadays commerce requires the interconnection of modern business communication systems with legacy voice networks. Demanding legacy requirements of a voice network can rapidly consume scarce capital and operational expense funds if not properly managed. An optimized network can ensure that resources are judiciously engineered and thus mind unnecessary expenditures from the organization's budget. This paper provides a high-level briefing of the leading practices that have application to network scaling in concert with business agility, change stemming from consolidation and mergers and managing the effect of discontinuous change. The paper introduces the application of capacity management techniques for an evolving voice network application. These practices have been applied to leading carriers resulting in huge quantifiable savings.

whitepaper The Search for the Right Packet Transport Technology: MPLS or PBB-TE (PBT)?2007-10-01 ECI Telecom
  This paper goes beyond the marketing hype and look closely at the underlying concepts behind MPLS and PBB-TE. The author does this in order to evaluate if there are any fundamental differences between the control or data plane of the two technologies, which would give either of them a significant cost/complexity advantage over the other. To further help providers select the best packet transport technology, the paper identifies key next generation packet transport requirements, and uses these as a benchmark to evaluate PBB-TE and MPLS.

whitepaper Voice over IP (VoIP) Implementation Guide for Network Performance Management2005-11-01 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.

whitepaper Measurement and Classification of Out-of-Sequence Packets in a Tier-1 IP Backbone0000-00-00 Sprint
  An important characteristic of any TCP connection is the sequencing of packets within that connection. Generally, if sequence numbers are monotonically increasing, then all is well - data flows through that connection without loss, and the network does not introduce pathological problems such as in-network duplication and reordering. Conversely, out-of-sequence packets indicate that the connection suffers from loss, duplication or reordering. This paper presents a measurement study and classification methodology for out-of-sequence packets in TCP connections observed within the Sprint IP backbone.

whitepaper SIP: Protocol Overview2001-12-06 RADVision
  The Session Initiation Protocol (SIP) is a signaling protocol for initiating, managing and terminating voice and video sessions across packet networks. SIP sessions involve one or more participants and can use unicast or multicast communication. Borrowing from ubiquitous Internet protocols, such as HTTP and SMTP, SIP is text-encoded and highly extensible. SIP may be extended to accommodate features and services such as call control services, mobility, interoperability with existing telephony systems, and more. SIP is being developed by the SIP Working Group, within the Internet Engineering Task Force (IETF). The protocol is published as IETF RFC 2543 and currently has the status of a proposed standard. This paper describes the key constituents of SIP.
