4.7. Conclusion and Future Research Areas

In this chapter, we have provided basic background on network survivability techniques, which are a critical component to providing information assurance in networked systems. We conclude with our opinions of future research areas for network survivability.

In addition to the multilayer survivability issues raised above in Section 4.6, several problems are receiving attention from the networking research community. There has been very little research on a systematic approach to end-to-end Internet resiliency. A specific issue that needs to be addressed is cost-effective access network survivability. In many cases, there are actually overlapping competing access network technologies serving a geographic ...
