QoS Perspective for Wireless Scenarios
White Paper This paper analyze QoS parameters from the network perspective looking on three different TCP/IP layers: Transport Layer (TCP and UDP), Network Layer (DSDV, DSR and AODV), and Medium Access Control Layer (DCF and EDCF). [18 Jul 2008]
Quality of Experience: A Strategic Competitive Advantage of Microsoft Unified Communications
White Paper As a substitute for direct management of Voice Quality, traditional IP telephony providers (and in particular those with a technical and cultural heritage in network solutions) have emphasized network level management of Network Service Quality... [28 Mar 2008]
Latency Comparison Between HyperTransport and PCI-Express in Communications Systems
White Paper Chip-to-chip interconnects directly impact overall communications system performance and can enable a new generation of IP-based services that deliver high Quality of Service (QoS) and flexible control. [14 Feb 2008]
A Simulation Study of QoS for TCP Over LEO Satellite Networks With Differentiated Services
White Paper This paper presents broadband LEO satellite network QoS model and simulated performance results. Currently, Internet Protocol (IP) only has minimal traffic management capabilities and provides best effort services. [14 Jan 2008]
Quality of Service for Voice Over IP
White Paper Quality of Service for Voice over IP discusses various Quality of Service (QoS) concepts and features that are applicable to voice - in particular, Voice over IP (VoIP). This paper also provides high-level examples showing how to deploy these... [08 Feb 2007]
End-to-End QoS Support for SIP Sessions in CDMA2000 Networks
White Paper This paper discusses how end-to-end QoS is supported in CDMA2000 networks using the IP Multimedia Subsystem (IMS) framework. In particular, the paper presents how IMS elements work together to facilitate QoS negotiation on the control plane and... [12 Dec 2006]
Load Balancing for QoS Enhancement in IEEE 802.11e WLANs Using Cell Breathing Techniques
White Paper The widely accepted IEEE 802.11b standard however, was not designed with such Quality of Service (QoS) constraints in mind. A new draft of the standard named 802.11e has been specified that deals with QoS issues for Wireless LANs. [09 Feb 2006]
Admission Region of Multimedia Services for EDCA in IEEE 802.11e Access Networks
White Paper In particular, this paper gives an estimate of the number of QoS-aware applications, namely videoconference and Voice over IP (VoIP), that can be admitted to the transport service offered by the EDCA while satisfying their QoS requirements. [07 Feb 2006]
Is VoIP drilling holes in your network?
News Because VoIP tries to have a quality of service (QoS) like real telephony, there is pressure to keep it as lightweight as possible, which unfortunately threw out stream-based encryption as part of the scenario. [23 Sep 2005]
Lessons on Freedom and Power: An End-to-End Network for Delivering Broadband for Government Organizations
White Paper This design guide considers the local-area network (LAN) technology needs - including critical requirements for security, redundancy, quality of service (QoS) and integrated management - of government agencies, organizations and institutions. [23 Aug 2005]
VoIP primer: How it works - and what the jargon means
Comment But IP, of course, was not designed to provide a guaranteed quality of service (QoS) to the traffic it carries; it was originally designed as a way of diversely routing data to ensure redundancy in case network nodes were being jammed, crashed or... [10 Feb 2005]
Gigabit Routers for Advanced IP Networks
White Paper This paper describes the GR2000, especially its high-speed processing, QoS functions, and IPv6 functions from the viewpoint of network solutions. Traditionally, networks have provided only "best-efforts-type services," which means "first come... [23 Dec 2004]
Optimal Admission Controllers for Service Level Agreements in Enterprise Networks
White Paper The transmission of multimedia streams with a particular and guaranteed level of QoS (Quality of Service) from source to destination is a major challenge in multimedia communications over IP networks. [15 Jul 2004]
Distributed Optimal Admission Controllers for Service Level Agreements in Interconnected Networks
White Paper The transmission of multimedia streams with a particular and guaranteed quality of service (QoS) is a major challenge in multimedia communications over IP networks. This paper presents the design and simulation results for a new distributed... [15 Jul 2004]
Mobile Evolution Towards Full IP Multimedia
White Paper In particular, real-time services rely on a strong end-to-end QoS approach, making use of MPLS and DiffServ capabilities. In a second step (2002), the 3G Core Network is extended by the adjunction of the IP Multimedia domain enabling new innovative... [24 Feb 2004]
