The Infrastructure Conference
Track i3: Interoperating Broadband Technologies

Track Leader:
Eric Martineau, Director
US West !nterprise Network

Track the ongoing debates about Internet technologies. Will D-WDM provide enough "free" bandwidth for terabit routers, and Class of Service technologies, to properly service the Internet backbone? Or will the internet’s hypergrowth and multimedia applications require true Quality of Service? This track will discus many Broadband "solutions" from Layer 3 centric, like IP, MPLS, and DiffServ, to Layer 2 centric, like Frame Relay over ATM, and MPOA. Find out about Mpeg Transport Streams to IP, Scaling the Internet Backbone, Network Design, Multicasting, Packet over SONET, traffic engineering, and Extending Public Network to Enterprise. This track will help you understand who is using what and why.

  • Will layer three routing paradigms, or layer two switching paradigms dominate the market, or is there a need for both, and if so where?
  • Is CoS enough for the Internet backbone?
  • If DIFFServ works well enough for the Internet Core, how will it be guaranteed throughout the Internet?
  • What will we do when IPv4 runs out of addresses?
  • Will IPv6 and Class of Service be enough, or will ATM addressing and QoS be the next logical step in the Internet’s hypergrowth?

Who Should Attend:
Internet developers, senior planners, and network managers and technicians.

Broadband Technology: A Look into the Future

As we move into the millennium, there is a re-convergence of applications and networks. Applications technology has moved toward a multi-tiered model, which assumes information flows over a network. The assumption, however, is still based upon a "best-effort" (IP) network model. Network technology is moving toward a finite tiered service level based model that allows policies to dictate service levels on an application basis. The convergence is happening in the mapping of the applications over the network. This transparent mapping enables new business solutions leading to an increased competitive advantage. Products and technologies that enable this convergence allow for an application aware network. These products enable the IT user to optimize their operational costs, improve reliability and build scaleable solutions.

In this session, we will discuss the types of networking technologies that can be used to build an efficient core IP network. We will compare and contrast IP, ATM and MPLS technologies on the basis of technical stability and interoperability, traffic engineering, network reliability, bandwidth efficiency, and support for multi-service networking. We will show how each protocol can be used to deliver multiple classes of service (CoS) and service level agreements (SLAs).

  • When will the pragmatic market adopt applications that demand CoS or need QoS?
  • In the mean time will CoS be enough, or do we need QoS now?
  • Are today's routers ready to handle large volumes of streaming media? What improvements in routers are required for reliability, scalability and ease of management to build the public IP network?
  • What constitutes a flow?
  • Can IP and or ATM completely take over all communications?
  • What are the best practices for the separation of routing and forwarding performance?

Pragmatic Approach to IP over Everything

The first component of the session will segment the various sources of IP traffic demand and discuss their particular attributes and growth rates. This session will also address the issue of backbone scalability from multiple layers of the OSI stack. At the physical layer, the discussion will address the decisions and key issues on physical network overbuilds and equipment vendor selection. From a link-layer perspective, the session will discuss the trade-offs in using IP over DWDM, SONET, ATM and Frame Relay. From a transport perspective, this session will address how MPLS can serve to improve scalability and improve performance.

The presentation then shows a specific approach of interworking the different services and enabling them to be transported over different networks (TDM, ATM or IP) which utilizes standard protocols and interfaces. The interworking functions will be illustrated by protocol stack diagrams. Essential parameters such as latency and QoS will be briefly addressed in the course of the presentation to show that they are taken into consideration.

Debating aside, the real issue that network administrators face is that the technologies we have today, namely TDM, ATM and IP will be here tomorrow and for the foreseeable future. The problem can only be solved by enabling those technologies to interoperate smoothly and transparently to the end user. It is also interesting to observe that there is a great focus on voice services and how those can be integrated with data services on the same network(s).

  • What are the roadblocks to scaling the backbone effectively?
  • What are the Issues relative to scaling the IP backbone to handle the expected volume of data and telephony users?
  • Why do we need Switched Services to achieve the highest economical and widest connectivity advantages?

Merging Layer 2 and 3 Technologies Enables Next-Generation Internet Services

To meet the service needs of an increasingly sophisticated market, service providers must be able to adapt existing technologies as well as tap new ones. Terabit capacity router through-put combined with industry convergence on IP, QoS based routing, connection-oriented resource reservation, real-time transport, voice and multimedia, SS7 and security protocols to IPv4, are forcing providers to fully integrating the efficiency of Layer 2 transport with the intelligence of Layer 3 routing. In this presentation we will discuss the technologies involved in merging Layer 2 and Layer 3 networks. We will also explore potential next-generation Layer 2 Dynamic synchronous Transfer Mode services, as well as examine the technical factors involved in bringing all these services to fruition, to meet the current & future needs of both public and private network operators.

  • What are the technical factors necessary for success in the next-generation Internet?
  • What types of services will we see as the Internet evolves?
  • What will it take to implement next-generation services?
  • How can you lower the cost of network ownership and offer revenue-generating services today?
  • What technologies can respond to the fast and changing demands of converging datacom and telecom services?

Integrating ATM-MPLS Service Platforms

Increasing demand for new IP-based services, particularly IP-based VPNs, requires the ability to "engineer" network traffic. MPLS is seen as a key mechanism to enable "traffic engineering" and deliver these new IP-based capabilities utilizing the QoS features of deployed ATM infrastructures. For these reasons service providers have expressed great interest in ATM-MPLS integrated platforms.

The ability to provide QoS in data centers is where a new role is emerging for flow switching-based network devices, highly optimized for Internet Protocols and services. Devices based on Flow Switching will be able to combine the traditional attributes of packet switching devices like LAN switches, including performance and scalability for connecting Web servers, with complex policy management for Web traffic including security, load balancing, and Quality of Service. This session will explore the techniques and mechanisms used in these new flow switching devices, and the benefits that are derived for mission critical Web sites.

This session will cover the value of traffic engineering in large IP networks, provide a brief primer on MPLS and its current status. We will also look at MPLS as an integration technology between the optical, switching and routing planes.

  • How can "traffic engineering" provide QoS with MPLS over ATM?
  • How will vendors supporting MPLS in ATM switches - new and legacy systems?
  • Which is better Layer II VPNs or IP-based VPNs
  • What are the network management challenges from MPLS?
  • How will flow switching and packet switching impact Web response times?
