Networking research can be broadly categorized into two directions: understanding and improving current networks, and imagining future networks and related protocol/technology research and development. Significant research continually improves current features of the Internet, a prime example of a Â“future networkÂ” when it was envisioned over 30 years ago. External forces can also play a critical role in networking research (for example, the deployment of services that become popular overnight because current networks can support them). This phenomenon raises additional issues that can feed into either of the two broad directions. In this talk, I'll discuss a few historical examples and summarize the current trends and obstacles in networking research, addressing the need for both short- and long-term networking research directions.
