By converging voice and data traffic into a common network based on Nuera’s packet voice technology, competitive local exchange providers can reduce their cost-of-ownership and deliver high margin services. The carrier industry has experienced double-digit growth rates during the past 4 years and the strong growth continues even today as more and more consumers subscribe telephony services. The rapidly growing subscriber base along with the dropping per-minute usage charges due to increased competition is causing concern to the service providers recently.

On Improving the Throughput of Media Delivery Applications in Heterogeneous Overlay Network
http://www.recursosvoip.com/docs/english/Globecom06-Netcoding.pdf
Fuente: Microsoft
Formato: PDF
Overlay multicast is becoming increasingly popular for multimedia delivery over Internet. The available bandwidths between sender and different receivers are generally heterogeneous. This paper proposes a scheme to improve the throughput of a media delivery session with heterogeneous receivers by organizing the receivers into layered data distribution meshes and sending substreams to each mesh using layered coding. The solution utilizes alternative paths and network coding in each mesh. The paper first formulates the problem into a mathematical programming, whose optimal solution requires global information. It therefore presents a distributed heuristic algorithm. The heuristic progressively organizes the receivers into layered meshes. Each receiver can subscribe to a proper number of meshes to maximize its throughput by fully utilizing its available bandwidth.

On-board IP architecture - a new approach to computer telephony card design
http://www.recursosvoip.com/docs/english/Aculab_IParchitecture.pdf
Fuente: Aculab
Formato: PDF
As the computer telephony (CT) industry has evolved to deal with the emergence of VoIP and IP telephony, the notion of separate digital signal processing (DSP) resource cards and IP connectivity or gateway cards has evaporated. Just like the demise of traditional, single function digital network access cards, fax cards, and voice processing cards in favour of combined products, such as Aculab’s Prosody.
Multi-purpose, multi-function cards are now the norm and the industry is looking to where these latter-day design concepts can be improved – yet still operate within the industry accepted form factor specifications.
This paper presents an alternative to the traditional PCI driven parallel bus architecture for the core, on-board design of versatile, multi-function CT resource cards. It demonstrates a ‘think outside the box’ approach that combines adherence to standards with optimum use of prevalent technologies.

Pingtel's new Enterprise Communications Model, based on Enterprise-grade open source software, empowers Small-to-Medium-sized Businesses (SMB) with the ability to decide when and how to use Voice-over-IP (VoIP) technologies. Businesses can choose to use the Enterprise-grade VoIP solution at any stage in a deployment, whether it's in conjunction with an existing traditional-phone system, an upgrade to another vendor's VoIP system, or a new build; technologies and vendor solutions can be mixed and matched. It's a radically different solution. It invites competition. The simplicity of an open source model creates obvious cost benefits and value for businesses.

Much importance has been rightly given to providing voice services over Internet standard networks, but this is only one possible application. The potential future impact of using general purpose computing hardware and languages to develop "Telephony" and/or "Converged" systems and networks will continue to broaden. This paper will review the value proposition for convergence in general and discuss the benefits of data center based applications compared to the proprietary world of telephony. It will then describe Oracle's Voicemail solution and how Oracle Voicemail takes advantage of convergence.

Overview of the Session Initiation Protocol

Formato: PDF
Session Initiation Protocol (SIP) is the Internet Engineering Task Force's (IETF's) standard for multimedia conferencing over IP. SIP is an ASCII-based, application-layer control protocol that can be used to establish, maintain, and terminate calls between two or more end points. Like other VoIP protocols, SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call.

Multi-Protocol Label Switching (MPLS) has often been presented as a technology that will help service providers deliver better performance and availability, including specific benefits in support for demanding applications such as voice and video. Many service providers have implemented MPLS technology in their core networks. Now, with MPLS backbones in place, these carriers are offering MPLS-based services to enterprise customers in support of Voice over IP (VoIP) and video applications. This paper presents the results of the test setup used to measure the impact of Avaya CNA across a real-world IP WAN network of both MPLS and Internet links.

The emergence of a new standard, IEEE 802.3af or Power over Ethernet, is changing the way we think about powering network components. It is now possible to power, from a central point located at the distribution/edge switch, a number of network devices through the same standard cable that is used for data communication, and that is already installed in most enterprises. This paper explains how by using MGE UPS Systems power protection devices, IT and facility managers and users can get the same level of availability from their VoIP architecture as they experience with the traditional circuit switched telephony systems.

RFG believes the transition to IP telephony and enterprise convergence is inevitable due to the decreased capital and operational expenses, and positive business impacts of packet-switched telephony. However, the migration path from today's technology to tomorrow's packet-switched converged systems will be a unique process for each corporation based on current product platforms and a host of organizational and economic variables. IT executives should begin developing plans now for a logical migration path to move their enterprises forward to take advantage of the inherent economies and simplicity of IP telephony.
