Optical + Ethernet: Converging the Transport Network

Jim Gerrity, Adva Optical Networking

Constantly expanding demands for network bandwidth continue to drive the adoption of multi-wavelength optical technologies in metropolitan and regional core transport networks. Simultaneously, the ubiquity and economics of Ethernet access devices are driving demand for efficient, reliable delivery of Ethernet-centric services. Further, the constant introduction of new and innovative applications into the network demands an ever-increasing degree of flexibility and reconfigurability from the network architecture. This combination of bandwidth demand, cost advantage and new applications is driving the emergence of a new generation of transport networks comprised of three specific technologies: reconfigurable DWDM optical transport, carrier-grade Ethernet service delivery, and the unified GMPLS-based network control plane. This session describes and organizes the many new data plane and control plane technologies emerging from various standards development activities, which are intended to enable construction of converged Optical + Ethernet transport networks. Technologies discussed include the Virtual Private LAN Service (VPLS), Transport-MPLS (T-MPLS), Provider Backbone Bridge (PBB) and Provider Backbone Bridge with Traffic Engineering (PBB-TE) technologies, and the evolving Generalized Ethernet Label Switching (GELS) architecture. This session further provides examples of how these technologies can be combined with existing reconfigurable DWDM transport elements and Ethernet access devices to form a new, unified transport network architecture. Details of two research-oriented networks incorporating early Optical + Ethernet concepts (NSF Dragon, EU Phosphorus) are also discussed. The advent of new optical transport elements with Layer 2 awareness, combined with Ethernet delivery elements with improved service awareness and OA&M capabilities, has the potential to significantly alter how metro and regional transport networks are conceived, deployed and managed. This session intends to provide the network architect and deployment manager, as well as clients of Ethernet network services, with a solid understanding of the options and benefits provided by a converged Optical + Ethernet transport network.

Networks for Dynamic Lightpath Connectivity for Researchers

Jim Archuleta, Ciena

The creation of dynamic lightpaths over Internet2 and other national and global networks will foster scientific computing and transfer of large data sets between institutions. Ciena will illustrate and outline solutions that address the building blocks for establishing ubiquitous and dynamic research network connectivity between research institutions worldwide. A key ingredient to this challenge is the optical switching and optical control plane technology which places intelligence in the optical layer by automating configuration, provisioning and restoration of the network. Ciena's poster submission will outline the technologies that make up optical switching and transport solutions that make dynamic lightpaths a reality.

Novel Dual-mode Fiber (DMF) Capable of Single- and Multi-mode Transmission

Hiromasa Tanobe, NTT Photonics Laboratories
Kazuto Noguchi, NTT Photonics Laboratories
Yoshihisa Sakai, NTT Photonics Laboratories

In an actual data transmission and data exchange field such as an internet data center (iDC) or a collocation center, the coexistence of two types of optical fiber, namely single- and multi-mode fibers, leads to increasing fiber management and ownership costs. We have fabricated a novel dual-mode fiber (DMF) compatible with both types of optical fiber for the first time. Single- and multi-mode transmission with this DMF technology was demonstrated with 10 Gbps data rates. By optimizing the DMF structure, we obtained a low splicing and return loss connection with a conventional single-mode fiber and a multi-mode fiber for 0.01 dB, >50 dB @ 1.31 ?m and 0.02 dB, >25 dB @ 850 nm, respectively. Moreover, a relatively low bending optical loss with 10 mm? was achieved for single- and multi-mode transmission, simultaneously. The DMF has a cylindrically symmetric structure. This structure provides not only the above features but also relatively flat transparent characteristics for the whole C wave band. These features promise the easy deployment of DMF in an iDC or a collocation center.

This patent-pending Distributed Network Switching Technology blurs the distinction between core switching and edge switching, enabling network build outs and performance upgrades of traditional chassis-based installations in a highly cost effective manner.

ENUM: Foundation for VoIP2

Cyril Matthews, VOEX
Bill Cartmill, VOEX

Today most IP destinations for voice, data, and multimedia traffic are "known" only to a single provider, creating VoIP islands. Service Providers are forced use the PSTN as a bridge between these islands for two primary reasons: (1) the immaturity of key protocols that support IP applications, and (2) the lack of a structured approach to managing and sharing information about users. In the future, all networks will interoperate using IP end-to-end to deliver on the promise of better cost and richer features, including those presently in development as a part of the next-generation communications architecture called IP Multimedia Subsystem (IMS). As part of this movement, the protocols and user data sharing mechanisms will be as stable and robust as in the PSTN. Taking one step along the path towards independence from the PSTN, some Service Providers have deployed ENUM databases, also called Registries, to help IP-based Service Providers route calls to their destination without the unnecessary and costly detour through the PSTN. The poster will illustrate the role ENUM registries will play in accelerating the movement toward a homogeneous IP multimedia network, reducing overall telephony costs, and setting the foundation for advanced applications.

VoIP2.0 Applications

Charles Studt, VOEX
Bill Cartmill, VOEX

Universities are faced with the problem of various constituencies using widely dispersed methods of communication with little interoperability. Faculty and staff use the universities' PBX and personal cell phones for most business calls. Students have migrated almost exclusively to wireless devices for voice and text messaging, and are early adopters of free or nearly-free voice services like Skype and Gizmo. While most use the universities' high-speed LANs for personal computer networking, the multiplicity of communications methods inhibits the knowledge exchange and collaboration universities strive to encourage. Applications that provide access to and interoperability between cell phones, VoIP services, legacy PSTN networks, and networked-connected personal computers are on the horizon. These applications will allow users to incorporate all of their contact information, personalize the method they are contacted based on parameters like time-of-day, and allow their multiplicity of contact information to be mapped to one identity. In addition, these applications will allow for the true integration of voice and data services, allowing for simultaneous voice and data media transmission from a single (or multiple) devices. They strengthen the learning environment and represent potential revenue and cost savings to the university community. This poster session will discuss the various elements necessary to implement the aforementioned applications, the increased real-time collaboration they represent to university constituencies, and the potential revenue opportunities.
