Abstract- A number of distance learning approaches have been proposed and practiced over the past few decades. Electronic learning (e-learning) through the Web is one of the most recent approaches to distance learning. E-learning has created a great deal of interest among the Internet users and has grown considerably fast over a few years. In addition to the universities, corporations have utilized this approach to provide training for their employees.
E-learning goes well beyond the delivery of textual data. For instance, a live lecture requires provisions for supporting the delivery of audio, video. Real time traffic (such as audio and video) is sensitive to delay and loss of packet data in a network. When the network load is light the quality of audio and video is reasonable, but the quality degrades rapidly in proportion to the network load. Under realistic scenarios the Internet load is often times highly loaded. Internet Protocol (IP) in its original form cannot guarantee a certain level of delay and loss. Consequently, Internet (in it original form) is not well suited for e-learning. However, the popularity and growth of Internet over the last decade has made it a very attractive media for multi media communications. In response to the need, new protocols have emerged recently by entities such as IETF (Internet Traffic Task Force) to address the real-time traffic delivery.
1.0 Introduction Many different approaches to distance learning have been proposed and practiced over the past few decades with varying levels of success -. E-learning is one of the most recent approaches to distance learning where Internet is utilized as the medium of the choice for the live and interactive delivery of lectures. The content of e-learning is somewhat different from what Internet has been used to. For this reason, e-learning cannot be looked upon as just another Internet application. In practice, e-learning presents a challenge to Internet and requires new transport protocols capable of providing real-time multimedia.
