whitepaper Secure Voice Over IP (VoIP) Solutions: Delivering a Robust, Secure VoIP Solution That Counters Both External and Internal Threats While Providing Superior Quality of Service2008-11-05 Alcatel-Lucent
  This paper discusses the key security challenges to consider when deploying VoIP solutions, and describes Alcatel-Lucent's VPN Firewall Portfolio and how it meets the security requirements of today's and tomorrow's VoIP networks and applications. Creating high levels of security is essential to fully leverage VoIP technology and the many advantages it offers over traditional wireline solutions. To meet this challenge, Alcatel-Lucent's VPN Firewall Portfolio provides a complete solution to cope with the evolving threats that can slow down the deployment and use of VoIP applications. The portfolio combines the Alcatel-Lucent Security Management Server, Alcatel-Lucent VPN Firewall Brick appliances, and deployment of the Alcatel-Lucent IPSec Client.

whitepaper Advanced QoS Methods for Grid Workflows Based on Meta-Negotiations and SLA-Mappings2008-11-05 Vienna University of Technology
  In novel market-oriented resource sharing models, resource consumers pay for the resource usage and expect that non-functional requirements for the application execution, termed as Quality of Service (QoS), are satisfied. QoS is negotiated between two parties following the specific negotiation protocols and is recorded using Service Level Agreements (SLAs). However, most of the existing work assumes that the communication partners know about the SLA negotiation protocols and about the SLA templates before entering the negotiation. However, this is a contradictory assumption, if one considers computational Grids and novel, commercially oriented computing Clouds where consumers and providers meet each other dynamically.

whitepaper Towards Scalable End-to-End QoS Provision for VoIP Applications2008-10-16 Institute of Electrical and Electronics Engineers
  The growth of the Internet and the development of its new applications have increased the demand for providing a certain level of resource assurance and service support. Recently, the IETF have proposed a new QoS architecture that implements IntServ over DiffServ in order to provide an end-to-end QoS for scalable networks. Hence, it became possible to provide and support a certain level of QoS for some delay sensitive and bandwidth-demanding applications such as Voice over Internet Protocol (VoIP). With regard to VoIP applications, delay, jitter and packet loss are crucial issues that have to be taken into consideration for any VoIP system design and such parameters need a distinct level of QoS support.

whitepaper Long Term Evolution Protocol Overview2008-10-01 Freescale Semiconductor
  This paper provides an introduction to how the Long term evolution (LTE) protocol stack operates. Because the final 3GPP specification will cover tens of thousands of pages, this paper touches only on the highest levels of protocol operation. The paper discusses the history and application requirements that determine the functions and priorities of LTE, examines the protocol stack in terms of the time domain and in terms of information moving through the stack, and finally discusses more specialized aspects of the standard such as scheduling and quality of service, management and control functions, handovers and power save operation.

whitepaper Adaptive TUF Packet Scheduling Scheme for OFDMA-Based WiMAX Systems2008-09-20
  WiMAX is a well-known broadband wireless access technology to support for different users in multimedia transmission. Its physical layer can be employed with Orthogonal Frequency-Division Multiple Access (OFDMA) technology. IEEE 802.16e has evolved five scheduling types of Quality of Service (QoS) for uplink transmission, but has not yet clearly defined the scheduling types for downlink transmission and described how to schedule the packets efficiently in BS taking into account their QoS. Many packet scheduling algorithms for WiMAX and OFDMA-based networks have been widely studied. This paper proposed an Adaptive Time-Utility Function (A-TUF) packet scheduling scheme to improve the QoS of RT traffic and the whole system throughput.

whitepaper Competitive Analysis of Buffer Policies With SLA Commitments2008-09-08 Institute of Electrical and Electronics Engineers
  This paper considers an abstraction of the problem of managing buffers where traffic is subject to service level agreements (SLA). The service provider must on one hand deliver all committed packets, and on the other hand can get extra revenue for any excess packet delivered. Using competitive analysis, they have shown how to utilize additional buffer space and link bandwidth so that the number of excess packets delivered is comparable to the best possible by any off-line algorithm, while guaranteeing that no arriving committed packet is ever dropped. Simulations of such traffic (alone and combined with additional best-effort traffic) show that the performance of the algorithm is in fact much better than analytical guarantees.

whitepaper ELAT for BusinessPartners: Offer Definition for Authorized BusinessPartners NAR Only2008-09-01 Avaya
  This paper describes the offer to make ELAT (ExpertNet Lite Assessment Tool) available to Avaya BusinessPartners in NAR. ExpertNet Lite Assessment Tool (ELAT) is a software application that can be used to verify a customer's network is ready for Voice Over IP (VoIP). ELAT simulates VoIP calls in the customer's network and gathers VoIP Quality of Service (QoS) measurements (delay, packet loss, and jitter), and Network Voice Quality (NVQ) for those calls. ELAT typically runs and collects data from testing for about a week. After gathering the QoS measurements, ELAT generates a report that shows whether the network is suitable for VoIP.

whitepaper Q-CAD: QoS and Context Aware Discovery Framework for Mobile Systems2008-08-08 Institute of Electrical and Electronics Engineers
  This paper presents Q-CAD, a resource discovery framework that enables pervasive computing applications to discover and select the resource(s) best satisfying the user needs, taking the current execution context and Quality-of-Service (QoS) requirements into account. The available resources are first screened, so that only those suitable to the current execution context of the application will be considered; the shortlisted resources are then evaluated against the QoS needs of the application, and a binding is established to the best available.

whitepaper Home Entertainment Networks and Flying Cars12008-08-05 1394 Trade Association
  Today's entertainment networks are reminiscent of the flying cars which have been promised for years but only seen in magazines or demonstrations. They are typically cobbled together from parts that require professionals to assemble and maintain, are expensive, and both have a tendency to crash when operated by someone with inadequate training. They also solve a similar problem. Highways, like most of today's networks, do not guarantee when the data will arrive at the destination. The problem is traffic.
