Overview
The rapid growth of the Internet and the imminent depletion of IPv4 addresses are posing increasing challenges on network routing and addressing. To enhance the scalability and performance of the network, continuing studies are needed to provide efficient routing schemes and addressing methodologies. While various schemes have been proposed to address some of the issues, a satisfying and deployable solution has yet to be identified. As such, research on the problems posed by the need for a scalable routing and addressing system for the Internet is needed. Issues include (but are not limited to) the scalability of the routing system, both in terms of state (the routing table) and rate (the dynamic nature of the network), securing the routing system, and "routing system economics". Note that these issues apply to both the IPv4 and IPv6 environments.
Routing and Addressing Scalability
- Existing proposals, such as, ID/Locator split
- Alternative or clean slate routing proposals: i.e., compact routing
- Address allocation
Routing Stability
- BGP updates
Routing Security
- Source Address Spoofing
Addressing
- NATs
- IPv4 to IPv6 addressing transitioning
Routing and Addressing Economics
- Economics and Policy of Routing and Addressing
Modeling
- Dynamical system characterization
- Mathematical modeling
- Topology generation
- Network topology analysis
Other Routing
- Multi-metric routing: such as, QoS routing
- Ad hoc routing
- Wireless routing
- Sensor network routing
