| Abstract | The distributed routing protocols in use today promise to operate correctly only if all nodes implement the protocol faithfully. A small insignificant set of nodes have, in the past, brought an entire network to a standstill by reporting incorrect route information. The damage caused by these erroneous reports, in some instances, could have been contained since incorrect route reports sometimes reveal themselves as inconsistencies in the state-information of correctly functioning nodes. By checking for such inconsitencies and taking preventive action, such as disregarding selected route-reports, a correctly functioning node could have limited the damage caused by the malfunctioning nodes. Our theoretical study attempts to understand when a correctly functioning node can, by analysing its routing-state, detect that some node is misimplementing route selection. We present a methodology, called Strong-Detection that helps answer the question. We then apply Strong-Detection to three classes of routing protocols: distance-vector, path-vector, and link-state. For each class, we derive low-complexity self-monitoring algorithms that take as input the routing state and output whether any detectable anomalies exist. We then use these algorithms to compare and contrast the self-monitoring power ofthese different classes of protocols in relation to the complexity of the irrouting-state. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
