  3. 3. ABSTRACT Here we investigate pricing of Internet connectivity services in thecontext of a monopoly ISP selling broadband access to consumers.Time-varying consumer utilities for broadband data rates that can resultin uneven demand for data-rate over time. Practical considerations limitthe viability of altering prices over time to smoothen out the demandeddata rate. Regulatory attention on ISP congestion managementdiscourages such “technical” practices and promotes economics basedapproaches. We characterize the loss in ISP revenue from an economicsbased approach. Regulatory requirements further impose limitations onprice discrimination across consumers, and we derive the revenue loss tothe ISP from such restrictions
  4. 4. Introduction The impact of access prices on the congestion management practices and revenue of a monopoly ISP, operating a single bottleneck link with fixed capacity. Internet data flows along multiple links on a route between source and destination, the end-user access link is typically the most constrained for capacity, and the major contributor to the connectivity price. Consumer data rate allocation can be determined by socially optimal prices in a competitive market on the one hand, or the revenue maximizing prices in a monopoly ISP market on the other hand. The analysis in this paper explores the latter and represents a benchmark: the most favorable outcome to the ISP and possibly the least favorable outcome to the consumers.
  5. 5. EXISTING SYSTEM Pricing content-providers for connectivity to end- users and setting connection parameters based on the price is an evolving model on the Internet. The framework generalizes the well-known utility maximization based rate allocation model, which has been extensively studied as an interplay between the ISP and the end-users, to incorporate pricing of content- providers. We derive the resulting equilibrium prices and data rates in two different ISP market conditions: competition and monopoly. The surplus gains are, however, limited under monopoly conditions in comparison to competition in the ISP market.
  6. 6. PROPOSED SYSTEM• Internet data flows along multiple links on a route between source and destination, the end-user access link is typically the most constrained for capacity, and the major contributor to the connectivity price.• We quantify that a significant component of the monopoly ISP revenue is from flat price if consumer price sensitivity is low and through usage price if consumer price sensitivity is high.• Flat pricing is generally considered as the preferred choice of consumers, but our analysis indicates that flat pricing can lead to a significant loss of consumer net-utility, particularly when the consumers have low price sensitivity.

  16. 16. Conclusion Reliable transmission of packets over intrinsically unreliable channels such as lossy wireless links. In a modern high-speed wireless data network, however, multiple parallel channels between adjacent transmitter–receiver pairs are often created using advanced wireless communication technologies systems increase the data transmission rate. Unlike packet transmission over a single channel, in a multichannel communication system, multiple packets are sent at a time, one packet per channel, and packet transmission errors can occur across every channel.
