Generalised Repair for Overlay Networks

Proceedings of the 25th IEEE Symposium on Reliable Distributed Systems (SRDS 2006), Leeds, UK, 2-4 October, pp. 132-142, IEEE Computer Society, 2006 (11p.)

We present and evaluate a generic approach to the repair of overlay networks which identifies general principles of overlay repair and embodies these as a reusable service. At the heart of our approach is an algorithm that discovers the extent of a failed section of any type of overlay, and assigns responsibility to carry out the repair. The repair strategy itself is 'pluggable' and can be tailored to the requirements of a specific overlay type or instance. Our approach is efficient in terms of the number of repair-related message exchanges it incurs; scalable in that it involves only nodes in the locality of the failed section of the overlay; and resilient in that it correctly handles cases in which multiple adjacent nodes fail simultaneously, and it tolerates new failures that occur while a repair is underway. The benefits of our approach are that: (i) it extracts and encapsulates best practice in repair for overlays; (ii) it simplifies the design and implementation of new overlays (because repair issues can be treated orthogonally to basic functionality); and (iii) it supports tailorable levels of dependability for overlays, including pluggable repair strategies.
