Voice over IP (VoIP), video streaming, instant messaging, multimedia conferencing, and interactive gaming are just some of the real-time, IP-based applications enjoying rapid growth in today's competitive communications market. Service providers are now finding it efficient and economical to directly interconnect their IP networks to both customer and other service provider IP networks. This trend has created a requirement for Session Border Controllers (SBCs) to help service providers control and manage real-time multimedia communications sessions at the borders between their IP networks. This paper explores the various ways service providers are deploying SBC capabilities in their networks, and discusses the Cisco portfolio of network components with integrated SBC functions.

Service Architectures in H.323 and SIP – A Comparison
http://www.recursosvoip.com/docs/english/Service_Architecures_SIP-H323.pdf
Fuente: Siemens
Formato: PDF
One of the major challenges for next generation IP networks is to provide multimedia teleconferencing services. Moreover, the introduction of new services includes the take over of traditional telephony. Besides the general problems with supporting realtime services in the IP network (e.g. QoS), this puts a special interest on the control of supplementary services and on the mechanisms for their fast and efficient development and deployment. The two most promising approaches in the multimedia over IP area are the protocol suites H.323 (ITU-T) and SIP (IETF). Several comparisons of these two protocols have been published already, but their service architectures have been rarely addressed. This survey provides a comparison of H.323 and SIP, focussing on their service architectures. The basic protocol architectures are reviewed, followed by an in-depth evaluation of their service implementation mechanisms. The studies are backed up by detailed examples for the control of supplementary services in H.323 and SIP.

Fast and efficient development and deployment of new services are important drivers for advanced multimedia business. In the Internet world the standards of the ITU-T (H.323) and of the IETF (SIP) are of most importance for advanced telephony services. Although labeled with "Voice over IP" these architectures provide far more services than just setting up voice calls. The expectations and requirements are: Providing those services that are well known from traditional telephony and offering mechanisms to support the implementation and integration of new features. The comparison of the two standards in this paper focuses on their service implementation concepts.

The adoption of open, flexible, standards-based service creation environments (SCEs) is critical for the rapid introduction of new services and business models into emerging Next Generation Networks. These SCEs in turn will need to interact with a variety of the underlying building blocks of these new services. Out of all of these, the most important is Session Initiation Protocol (SIP), already in wide scale deployment around the world supporting Voice over IP hosted services, enterprise IP PBX systems and client/server desktop applications, as well as playing a vital part in the Internet Multimedia Subsystem (IMS) architectures of both fixed and mobile service providers.
This document explains the central role that SIP Application Servers and SIP Servlet-based Service Creation Environments have in supporting a wide range of new services and new communities of interaction.

Session Initiation Protocol Services Architecture
http://www.recursosvoip.com/docs/english/0900940380044982_White_paper.pdf
Fuente: Lucent Technologies
Formato: PDF
The session initiation protocol (SIP) is a unifying protocol for providing integrated telephony and Internet types of services, such as Web, presence, instant messaging, and chat. To provide for the integration of these disparate types of services, considerations must be given from a network point of view. However, little attention has been given in the literature to identify the network elements required to provide these services or the mechanisms for integrating these different types of services for end users. This paper describes a network-level services architecture for SIP, including network functions and entities needed to support the services integration. We will discuss how services can be incorporated at different levels in the network, and the types of services typically created at each of these levels. We will also describe a service access and mediation function, which blends disparate types of services in creating a seamless and rewarding user experience.

Simplifying IP Networking with the 5E-XC Switch

Fuente: Lucent Technologies
Formato: PDF
One of the next-generation IP services supported by the 5E-XC Optical Interface Unit (OIU) on the 5ESS Switch is packet trunking. The OIU will support TDM OC-3/STM-1 interfaces as well as Packet Over SONET/SDH (POS) OC-3c/STM-1 interfaces, allowing IP-based trunking between switches. A common concern for service providers interested in offering IP trunking will be the creation of the packet network infrastructure necessary to support IP trunking. This white paper examines 5E-XC IP trunking and requirements for the IP network. It proposes a first step for creating a router-based IP network configuration that introduces IP trunking without adding complexity, and presents a variety of possible redundancy schemes. Router products from Juniper Networks that meet the needs of the IP trunking network are also identified.
