Abstract

Background/Objectives: The current IP based internet architecture may not fulfill the needs of the future. The major problem being that the IP addresses are exhausting at a faster rate. Methods/Statistical Analysis: The proposed architecture for E-mail application on Named Data Networking uses SMTP and IMAP protocols to transfer mails over NDN. To enhance the overall performance, concept of long lived interest is used for implementing PUSH protocol for communication between the user agent and the servers. Further to retrieve the lost packets selective reject mechanism is used instead of the go back N mechanism. Findings: One major advantage of the NDN architecture is its Content Store. Content Store plays a vital role in minimizing the traffic in the network through the caching system. The major improvement in our E-mail application is the introduction of the concept of long lived interest. We have recorded our results by varying the number of mail segments. Results showed drastic performance improvement with long lived interest as the total number of packets is reduced drastically. We have measured performance by calculating the time required for the segments to reach the receiver mail server with and without the packet drops and by varying the number of mail segments. The results clearly indicate that the performance is better when there is no packet drops as there is no packet retransmission. Improvements/Applications: Packets from the mobile node takes longer time than the wired nodes because of the air medium interference, thus we intent to reduce the time taken to transfer packets in the mobile nodes.
