For service providers that have exhausted DS3's capacity, the Synchronous Optical Network (SONET) standard allows the creation of >150 Mbps highly available data links between routers. This presentation covers the basics of the standard, including:

• History and motivation
• Frame structure and bit rates
• SONET multiplexers
• Topologies and redundancy

This talk focuses on the practical aspects of integrating Dynamic Packet Transport (DPT) into existing Synchronous Digital Hierarchy (SDH) networks. Topics covered in the talk include:

• What are DPT and SRP (Spatial Re-use Protocol)?
• Integrating DPT into your exsisting SDH network
• Removing the "transport" layer
• DPT and robustness
• SRP and the fairness algorithm
• Deployment issues and models
• Real world deployment example VersaTel is currently considering the deployment of this technology. Hence, this presentation is simply a theoretical look at the new technology.

This is not another talk detailing "How to prepare for the Year 2000 computer problem." We assume that NANOG attendees know what the problem is, and have already taken steps to address it. This session is about what happens after you think you have fixed your own problems. A failure may still result from something overlooked, or an unexpected combination of factors. In any case, Murphy's Law will not expire after December 31, 1999.

Because the Internet is a network of networks, in addition to preparing a contingency plan for your own network, you should prepare to maintain your network as part of the Internet. There is potential for numerous, small-scale disruptions across the country which overwhelm normal inter-provider NOC communications. This presentation outlines contingency planning steps providers should take to prepare for potential communications problems.

A report on the activities of "The Internet and the Millennium Problem" Working Group of the IETF. A thorough investigation of how Y2K issues will affect the operations of Internet-related protocols was conducted by the IETF. The complete results will be published in an upcoming RFC. This presentation will give a quick overview of the issues discovered and how they may affect operations.

SURFnet, the Dutch national research and education network, is a player in the GigaPort Project. GigaPort consists of two interrelated sub-projects, GigaNet and GigaWorks. Within the context of GigaNet a highly advanced communications network is being developed with super-fast connections across The Netherlands and Europe and to North America and Asia. GigaWorks offers the Dutch business community the opportunity to carry out large-scale research into new applications for the next generation of the electronic highway.

SURFnet operated an OC-12 speed backbone across The Netherlands with a 200 Mbit/s connection to North America and a 155 Mbit/s connection to TEN-155, to which most other European national research and education networks are connected. SURFnet is connected to the STAR TAP in Chicago, IL and has a direct connection to Abilene.

Full Abstract

This talk highlights the tradeoffs between the direct circuit interconnect model and the exchange point interconnection model for ISPs. The paper discusses the operations and financial models (taking into account the circuit costs, cost of exchange participation, cost of dark fiber, etc.) and the implications of these strategies across the number of interconnection participants and bandwidth utilization between the participants.

Major points to be presented include the following:

• For ISP interconnection, direct circuit interconnection is financially attractive for low numbers of connections (O(5)) of relatively low bandwidth (DS-3/OC-3). This is due to the fact that ISPs typically pay only half of the cost for the direct circuits between each other, while they pay the full freight for the big pipe into the exchange. ISPs may want to use the exchange for a POP, but barring use like that, if all one wants to do is exchange traffic with these other five folks into the foreseeable future, the direct circuit interconnect model makes sense.
  
  
• As the bandwidth and number of interconnections grow, the exchange point interconnection model proves much more scalable for two reasons. First, as bandwidth grows between participants, ISPs are able to aggregate interconnection traffic over increasingly large pipes back to their cloud, yielding potentially significant economies of scale. The direct circuit interconnection does not provide for this aggregation. Secondly, operationally, there are fewer backhoes in an exchange, fewer local loop providers to troubleshoot, etc. The greater the dependence on interconnection, the more hardened one wants that interconnection environment.
  
  
• Several of the exchanges also provide for the centralization of content, allowing additional transit sales revenue that potentially dwarf the cost savings highlighted above for interconnection. The direct circuit interconnect model doesn't allow for this additional revenue opportunity.
  
  

The analysis finds that facilities-based ISPs win big since (being able to exploit WDM technologies) they can seamlessly grow the pipe(s) into the exchange while the direct circuit interconnection model can't take advantage of this level of aggregation. These are among several of the dominant reasons for the IXP to be around well into the future.
