Abstract

During the last few years the Internet has grown tremendously and has penetrated all aspects of everyday life. The network services can be classified according to their level of QoS constrains, which describes how tightly the service can be bound by specific bandwidth, delay, jitter, and loss characteristics. At the first sight, three basic levels of end to end QoS can be provided across a heterogeneous network: The best-effort service, differentiated service (also called soft QoS), and guaranteed service (also called hard QoS), where an absolute reservation of network resources for specific traffic is provided through bandwidth reservation mechanisms. Quality of Service (QoS) by managing the delay, delay variation (jitter), bandwidth, and packet loss parameters on a network becomes the secret to a successful end-to-end business solution. It is the set of techniques to manage network resources.

Distribution applications such as video conferencing, distributed interactive simulations (DIS), Grid computing, storage area network (SAN), Distributed content distribution network (CDN) etc needs to transfer huge amount of data from a source to multiple number of designation. These types of data requires large amount of bandwidth, which is overcome with manycasting. The QoS constraints such as Physical layer impairments, delay, reliability, fault tolerance, data access latency, jitter etc., Optical Burst Switched (OBS) network is used to solve some of the QoS constraints to an extend such as delay, more bandwidth utilization than OCS network and Remove throughput limitation and Reduce processing requirements than OPS network. This paper deals with the detailed review of QoS, Manycasting and OBS network.

Abstract

We have several distance or similarity functions for trees, but their performance is not always adequate in different applications. In the base paper the Extended Sub tree (EST) function, where a new sub tree mapping is proposed. This similarity function is to compare tree structured data by defining a new set of mapping rules where sub trees are mapped rather than nodes. To reduce the time complexity as well as computational complexity of the system, efficient pruning algorithm is proposed. In the proposed system the unnecessary computation is reduced in the tree structured data by using the lossless pruning strategy. This paper provides major advancement in efficiency. This pruning strategy is ignoring the node or sub tree which has greater value than the ignoring probability. By using this technique, we can reduce the extra computation complexity.

Keywords

Abstract

The Paper emphasizes the advantages of Cloud Database Model and the necessity to ensure security level and data loss. In each and every segment of UF-CDB, the data accessing is verified and retrieved by set of tools. The tools are ID Generation tool, ID Verification tool, DB Connector Code generation tool, Database Download tool, Database Upload tool and DB Convertor tool. UF-CDB toolbar synchronizes the user with online database for maximum utility. By using these tools the data are protected in cloud database. In real world, to implement an enterprise server with multiple accessing point may cost very high and in the mean time, it is possible only by very large companies. But the small companies are not able to do the same thing. The UF-CDB provides the enterprise facility to everyone. So the small companies also get the facilities like large companies with minimum cost. The User Friendly Cloud Database also known as UF-CDB.

Keywords

Cloud Database, Online Database, API Based Database.

Abstract

Proper diet is the key to good health and vigour. Sensible and healthy food habits right from childhood coupled with good life styles can, not only delay aging and increase the life span, but also add to the quality of life. "Health for all by 2000 A.D." and All for Health" should encompass diseases due to inadequate as well as faulty diets.
