Hybrid Networking

Hybrid networking examines issues with using dynamic or static circuit-based networks. These issues include use of Layer 1 and Layer 2 end-to-end circuits as alternate paths to the default routed IP infrastructure, monitoring and troubleshooting of end-to-end circuits that cross multiple administrative domains, and use of non-IP protocols for wide area data movement.

The Hawaii Joint Techs hybrid networking focus session seeks presenters that are experienced or knowledgeable in the following areas:

• Practical experiences with production use of end-to-end circuits
• Emerging dynamic circuit services and capabilities
• Interfacing campus networks to wide-area circuit-based network services
• Development of interface standards and protocols for end-to-end circuit setup and teardown
• Monitoring end-to-end circuits extending across administrative domain boundaries
• Debugging and troubleshooting end-to-end circuits, dynamic as well as static
• Interoperability issues for deployment of circuit services

We are very interested in your presentations in these areas, or in other areas that define and explore the new challenges and that illustrate experiences in the hybrid networking area.

The Coming Crisis in Routing and Addressing

Several significant addressing and routing limitations in both hardware and software are converging into a "perfect storm" that could have a major impact on the stability of the Internet. These include:

1. Exhaustion of IPv4 address space and its impact on the size of the forwarding table.

2. Growth of the default-free FIB beyond the capacity of many popular routers.

3. "Churn" resulting from the acceleration of the growth in prefixes advertised in BGP is reaching the point where processors in popular routers can no longer converge forwarding tables between updates.

4. Deployers of global network resources (storage and computing) have been forced into NAT and application gateways, even in North America.

5. Early deployers of IPv6 for wide-area services have encountered problems involving both loss of reachability in some cases, and even faster growth of the hardware resources needed.

This focus area will look at the nature and scope of the problem and at possible approaches to dealing with it with IPv4 and IPv6. These may involve hardware and software changes including fairly fundamental changes in how global routing is done.

Security

We're encouraging presentations that complement other workshop focus areas, including hybrid networking, the coming crisis in routing and addressing, and future architectures, or presentations that speak to other timely issues, including but not limited to:

• Firewalls present issues of traversal connectivity and performance impact. What are the issues and how are they being addressed today? What are the best long-term strategies for solving these and related future problems?
• What are important security strategies and considerations for IPv6?
• Network management and security management have a large set of overlapping concerns, requirements, monitorings, and actions -- often the responsibility of distinct organizational units. What are some outstanding examples of shared processes and tools, and interorganizational communications and management?
• What are the unique security considerations for hybrid networks?
• What are effective practices for supporting disparate policy approaches on different "host groups" -- lambdas, firewalls, special filters, proxies, reverse proxies, application gateways, NAT, etc.?
• What are security considerations and best practices for VoIP? Enterprise concerns include both enterprise-wide systems and the implications of desktop VoIP. Some possible areas of interest are: Skype SuperNodes, SPIT (Spam over Internet Telephony), spoof prevention, SIP Asserted Identity, and SRTP (Secure Real-time Transport Protocol).
• What are the current considerations for DNS security? How healthy is the research and education DNS infrastructure? What are the security challenges? How will DNS be important to protection methods being developed, and does that open the door for new security challenges? What is the status and future of DNSSEC?
• CALEA -- policy and technical considerations.

We welcome presentations that define and explore the new challenges and that illustrate experiences in these areas.
