In a network system, there inevitably be a few connection failures at nodes, such as delay.
Once a failure occurs, the network administrator must detect failure sources as soon as …

A monitoring mechanism combining the advantages of a monitoring trails scheme and an
optical coding scheme is proposed; the mechanism can be used in a metro-access network …

Boolean network tomography can limit optical nodes on which electronic monitors need to
be placed in all-optical mesh networks. However, required monitoring cost for operation and …

In combinatorial group testing problems the questioner needs to find a special element x ∈
nx∈ n by testing subsets of n. Tapolcai et al.(in: Proceedings of IEEE INFOCOM, Toronto …

This paper deals with fast node failure localization in optical networks with monitoring trails
(m-trails). It is based on Network-wide local unambiguous failure localization, which enables …

Precise, fast and scalable fault localization is a highly desired feature in all optical mesh
networks. The monitoring trail (m-trail) framework has been long in use for centralized failure …

In combinatorial group testing problems Questioner needs to find a defective element x∈[n]
by testing subsets of [n]. In [18] the authors introduced a new model, where each element …

In combinatorial group testing problems Questioner needs to find a special element $ x\in [n]
$ by testing subsets of $[n] $. Tapolcai et al. introduced a new model, where each element …

In all-optical networks, monitoring trail (m-trail) has long been proposed as an effective way
for link failure localization. Previous works tried to minimize the number of used m-trails for …
