Abstract:- -Currently internet client varies widely both in hardware and software properties. The ever increasing requirements of clients to support heterogeneous environment, demand techniques to adapt the same content to diverse devices by pervasive computing. Content service may perform media conversion such as from text to audio. The transcoding function changes the data from one format into another. To address all these types of variation and to provide a suitable content and presentation to client proxy-based transcoding approach is used. The computational load caused by object transcoding is shared among the proxies by flexible delegation of services which reduces the transcoding load and provides fast response to the client. The data server also ensures data security by maintaining data integrity and confidentiality. The Lease Technique is proposed to ensure cache consistency among the intermediaries in CDN. A cache hit also reduces access latency for the clients. System performance thus improves, especially when a large amount of data is involved. Besides these improvements, caching makes the system robust by letting caching proxies provide content distribution services when the server is not available. With the emergence of various network appliances and heterogeneous client environments, there are other relevant new requirements for content services by intermediaries.
