In a conventional network, most network devices, such as routers, are dedicated devices that do not have much variation in capacity. In recent years, a new concept of network functions virtualisation (NFV) has come into use. The intention is to implement a variety of network functions with software on general-purpose servers and this allows the network operator to select their capacities and lo...

Watermarking belongs to hide particular information, so that you can easily detect any tamper detection .It is used for confidenality, authentication and copy right protection. In this paper watermarking is done with the help of least significant bit technique (LSB).As LSB technique is used as it has less effect on image. This new algorithm is using LSB of original image and idoing ‘&&’ operati...

Abstract We consider a generalization of the Hidden Number Problem for general moduli N , and prove that it can be solved with high probability if roughly 2(logN) aproximations of quality at least (logN) are given, and the multipliers are chosen uniformly at random from ZZ/NZZ. We prove a similar result in the case that the multipliers are chosen uniformly at random from (ZZ/NZZ) and N is the p...

Recently, Borgatti [Borgatti, S.P., 2005. Centrality and network flow. Social Networks 27, 55–71] proposed a taxonomy of centrality measures based on the way that traffic flows through the network—whether over path, geodesic, trail, or walk, and whether by means of transfer, serial duplication, or parallel duplication. Most of the extant centrality measures assume that traffic propagates via pa...

The network measurement community has proposed multiple machine learning (ML) methods for traffic classification during the last years. Although several research works have reported accuracies over 90%, most network operators still use either obsolete (e.g., port-based) or extremely expensive (e.g., pattern matching) methods for traffic classification. We argue that one of the barriers to the r...

In this paper, we introduce a new channel model we term the q-ary multi-bit channel (QMBC). This channel models a memory device, where q-ary symbols (q = 2) are stored in the form of current/voltage levels. The symbols are read in a measurement process, which provides a symbol bit in each measurement step, starting from the most significant bit. An error event occurs when not all the symbol bit...

Given two comparative maps, that is two sequences of markers each representing a genome, the Maximal Strip Recovery problem (MSR) asks to extract a largest sequence of markers from each map such that the two extracted sequences are decomposable into non-intersecting strips (or synteny blocks). This aims at defining a robust set of synteny blocks between different species, which is a key to unde...
