Integrating IP and Optical Transport Networks Using GMPLS

Integrating IP routed networks with new and existing switched transport networks presents several challenges to the network operator and user community. Users of next-generation networks increasingly require the ability to rapidly provision end-to-end services essentially on-demand, ideally without knowledge of the details of the networks traversed by the service. Network operators are faced with significant challenges when provisioning these services, which may span both multiple network types and administrative domains. The Generalized Multi Protocol Label Switching (GMPLS) protocol suite provides both the network operator and the user community with a unified method for provisioning end-to-end services through heterogenous networks. Details of specific transport method and device characteristics are encapsulated in lower layers of abstraction, providing operators and users with single unified method for establishing and monitoring services.

Optical Network Design, Simulation, and User-Level Management of Lightwaves

This forum will briefly introduce regional, metro, and edge optical network design concepts, automated testing and simulation, and finally optical layer management and user control of wavelengths. The demand for optical networks within the Research and Education Community is rapidly increasing, however the funding of these networks is static. Combining the advantages of automated design, testing and simulation tools with the advanced capabilities of today's optical management software maximizes the technology / dollar ratio, resulting in an extremely dynamic, flexible, and cost effective procedure for optical network deployment. Furthermore, the increased interest from the scientific community to dynamically control wavelengths will be addressed and demonstrated. After the brief concept introduction, the forum will actually demonstrate optical design software and testing of a typical metro / edge optical network. Protection schemes, protocols, and design troubleshooting will also be discussed. Finally, the session will conclude with optical network management. Optical Management Software will display multiple R&E networks in real-time, and real-time management and user level control of the optical domain will be demonstrated on an off-site optical network. Specifically, performance monitoring (PM), in-service performance testing, and dynamic wavelength provisioning will be highlighted.

The Promise of SIP

The promise of SIP lies in the way that it combines fundamental capabilities for user mobility with an open-ended variety of user interactions over IP networks. "Remote collaboration" in the general sense is not a new concept in the academic community - it is more of a job description. Yet virtual teams today tend to use a patchwork of existing communication applications such as telephony, email and instant messaging. SIP enables the integration of audio, video and multimedia communication, application sharing, presence and instant messaging into a single framework that allows individuals and groups to interact when, where and how they want. The capabilities that SIP brings to the communications domain, especially when integrated with existing technology, greatly enhance the ability of researchers to extend the boundaries of human knowledge.

The Future of Real-Time Communications with Converged IP Networks

The emerging market of Unified Collaborative Communications (UCC) converged IP network of voice,
video, web and data collaboration and conferencing ) is changing the way geographically dispersed
groups collaborate and work. While many have entered the space with integrated voice and web
conferencing solutions, only Polycom has a complete end to end solution integrating voice, video,
web and data collaboration and conferencing into a single solution known as The Polycom Office.
In real time environments, UCC not only saves money by reducing the need for travel, it also
increases an organization's agility and competitiveness, delivering business value by enabling
faster time to decision and improving such areas as overall productivity, time to market, and
customer responsiveness. The Polycom Office fosters real time collaboration, simplifies system
management, improves productivity and motivates employees. Polycom's unique UCC solution is
focused on bringing people together to enhance the quality of their work and lives by increasing
the opportunities open to them. Now, even when you can't be there, you can be there with Polycom.

Terabit Centralized Shared Memory Switch Fabrics

Converged IP networks carry the triple-play traffic of voice, video, and data. Each traffic type requires different service levels,  placing differing requirements on the network elements. Voice requires good latency and jitter; video requires good jitter (and  sometimes multicast). Data may require bandwidth guarantees for large data transfers but other data such as e-mail, web access, file transfers, and IM can be best-effort service. Congestion happens in IP networks; constrained routing, outages with sudden BW shifting, DOS attacks, .... Under congestion, most current routers support service levels acceptable for best effort traffic; head-of-line-blocking by sharing fabric- or virtual-output-queues  among output ports prevent high service levels guarantees under heavy traffic loads. Triple-play networks require more stringent service levels. Reserving bandwidth and controlling jitter and latency for triple-play service levels requires independent output queues; these queues provide multiple levels of priority per port for full prioritization of  high-service traffic ahead of other traffic regardless of congestion level. Contrary to often-published assertions, shared-memory routers  do scale to terabit capacity and provide service level queueing for  high-bandwidth triple-play networks.

A New Feature in SIP Servers - B2BUA: Bringing Class 5 Functionality to SIP-BAS

SIP servers are one of the most closely watched network devices in VoIP. One of the most recent and exciting developments in SIP servers and SIP-based VoIP is the emergence of a feature called the B2BUA or Back-to-Back User AgentB2BUA takes what is traditionally a SIP end-to-end call and mediates it through a central SIP server, enabling service providers to manage and track a call from beginning to end, integrate and offer new value added features, and generally bring Class 5-type functionality to IP networks. In this session, we will explore B2BUA, a new technology that enables equipment manufacturers to develop voice and multimedia telecommunications equipment that seamlessly interwork with other communications networks, deliver centralized call and feature management, and provide end-users with advanced communications functionality, such as presence. Products that benefit from Back-to-Back User Agents include Softswitches, Application Servers, SIP-base IP-PBXs, Conference Bridges, FW/NAT traversal applications, 3G Servers and SIP Proxies.As IP telephony continues to mature and new features and functionality emerge that not only rival but surpass traditional telephony and multimedia communications, the need for advanced SIP development platforms becomes all the more important. RADVISION has been tracking both the needs of our development customers and the SIP standards bodies closely, and we now feel strongly that B2BUA, which enable true call control and protocol interworking, are now crucial features of any SIP communications product.The discussion of B2BUA functionality will include:
-Centralized call management due to the B2BUA s active participation in a call.
-Interworking with alternative networks by actively processing signaling and message bodies throughout the duration of the call.
-The enabling of SIP-based VoIP interworking between LAN and WAN.
-Advanced billing enabled by management and monitoring of the entire call state
-Cloaking of end point location, enabling both custom anonymizing services as well as replicating circuit-switched private number telephony services.

GLOBAL CROSSING 12:00noon

IP Backbone Capacity Planning & QoS

Two main approaches exist today for providing quality of service (QoS) in IP backbones. One approach relies on scheduling/queuing; the other relies on the presence of capacity/bandwidth. The two schools of
thought arise from different understandings of traffic characteristics. In this talk we present the results of an empirical study of Internet traffic characteristics. We use packet traces from a Tier-1 IP backbone
network and introduce a non-parametric approach to study latency characteristics at high utilization levels. This approach requires minimal assumptions and has broad applicability. The 2nd part of the presentation is focused on the Network Planning framework, applying the derived guidelines to large IP networks. Topics covered include failure simulations, the role of Diff-Serv in the backbone, and traffic matrix estimation.
