The creation of a digital society by means of networking, where everything is connected and is accessible from anywhere. However, despite their diverse adoption, traditional IP networks are complex and difficult to manage. It is both difficult to configure the network according to predefined policies and to reconfigure it to respond to faults, load and changes. Since the current networks are vertically integrated (the control and data planes are bundled together) make the networking even more difficult. Software-Defined Networking (SDN) is an emerging new paradigm that breaks vertical integration, separating the network’s control logic from the underlying routers and switches, promoting centralization of network control and introducing the ability to program the network. SDN makes it easier to create and introduce new abstractions in networking, simplifying network management and facilitating network evolution. In this paper I present an abstract survey on SDN. I start by introducing the SDN, explain its main concepts and how it differs from traditional networking. I provide an in-depth analysis of the hardware infrastructure, southbound and northbound APIs, OpenFlow focus at the existing platforms for SDN development and testing, including emulation and simulation tools, SDN controller implementations, as well as verification and debugging tools. In an effort to anticipate the future evolution of this new paradigm, I discuss the main ongoing research efforts and challenges of SDN.Keywords

In Tiruvallur district, Tamil Nadu paddy crop is cultivated in 96000 hectares with the production of 3.9 lakh tonnes. In Tiruvallur district number of operational holdings under marginal (0.00 – 0.99 ha) category is 185059 and under small farmers category is 22572. Effective utilization of farm waste in mushroom cultivation, as an allied agricultural activity under integrated farming system in doubling the income of farmers is being insisted by conducting skill oriented trainings to facilitate the complete knowledge of mushroom production activity on commercial scale in KVK, Tirur, Tiruvallur district. The present study was conducted to assess the impact of vocational training programme on knowledge about mushroom production in commercial scale and for self-employment at Krishi Vigyan Kendra, Tirur, Tiruvallur district Tamil Nadu. The results of the study revealed that knowledge gained from various lectures and demonstrations on mushroom production technologies was analysed by conducting pre and post evaluation tests and the results depicted that the post evaluation scores of gain in knowledge of various practices ranged from 64.00 to 98.00 per cent. The adoption of mushroom production on commercial scale by the participants was evaluated periodically and among the 37 participants of vocational training, 11 participants (29.72%) have started mushroom production at cottage level and are practicing sincerely. Thus, it can be inferred that exposure to training had increased the knowledge of participants regarding mushroom production. The technical support and supply of oyster and milky mushroom spawn through KVK is being facilitated to the farmers and rural youth of Tiruvallur district.Keywords

Chilli is famous for its pleasant aromatic flavour, pungency and high colouring substance. Among the spices, dry chilli contributes the major share in India (Revanappa et al., 1998). It is one of the important spices used very widely in culinary, pharmaceutical and beverage industries throughout the world. Chilli, both in ripe and green stage is an important condiment used for imparting pungency.India has emerged today as the foremost producer and exporter of chilli contributing to almost one fourth of world production. Number of plant growth regulators have been tried to control flower and fruit drop and to increase yields of Solanaceous crops like tomato, brinjal etc., but very little work has been done on chilli. Foliar application of NAA 40 ppm resulted in early flowering i.e., 34 days after transplanting. The treatment with NAA 40 ppm recorded the maximum number of flowers, fruits, fruit set, fruit length, fruit girth and 10 fruit weight.Keywords
