Streaming Internet Messaging Attachments This document describes a method for streaming multimedia attachments received by a resource- and/or network-constrained device from an IMAP server. It allows such clients, which often have limits in storage space and bandwidth, to play video and audio email content. The document describes a profile for making use of the URLAUTHauthorize

Unified Messaging using SIP and RTSP

Traditional answering machines and voice mail services are closed systems, tightly coupled to a single end system,the local PBX or local exchange carrier. Even simple services, such as forwarding voice mail to another user outside the local system, are hard to provide. With the advent of Internet telephony, we need to provide voice and video mail services. This also offers the opportunity to address some of the shortcomings of existing voice mail systems. We list general requirements for a multimedia mail system for Internet telephony. We then propose an architecture using SIP (Session Initiation Protocol) and RTSP (Real-Time Streaming Protocol) and compare various alternative approaches to solving call forwarding, reclaiming and retrieval of messages. We also briefly describe our prototype implementation

Mobility Study for Named Data Networking in Wireless Access Networks

Information centric networking (ICN) proposes to redesign the Internet by replacing its host-centric design with information-centric design. Communication among entities is established at the naming level, with the receiver side (referred to as the Consumer) acting as the driving force behind content delivery, by interacting with the network through Interest message transmissions. One of the proposed advantages for ICN is its support for mobility, by de-coupling applications from transport semantics. However, so far, little research has been conducted to understand the interaction between ICN and mobility of consuming and producing applications, in protocols purely based on information-centric principles, particularly in the case of NDN. In this paper, we present our findings on the mobility-based performance of Named Data Networking (NDN) in wireless access networks. Through simulations, we show that the current NDN architecture is not efficient in handling mobility and architectural enhancements needs to be done to fully support mobility of Consumers and Producers.Comment: to appear in IEEE ICC 201

Technologies of online learning (elearning)

This chapter includes an examination of some of the most exciting technologies and features used in online instruction today, and those we may use tomorrow. Education is one of the fastestgrowing economic and social sectors in the world, and the use of new technologies is an integral and driving component of that growth

Using Technology To Create A Dynamic Classroom Experience

There are a multitude of diverse technologies available for integration in the college classroom, but considering how to implement these initiatives can be overwhelming to the instructor.  The adaptation of this technology is often very simple and involves little more than the Internet and basic word processing skills.  A review of the multimedia applications, which are inexpensive (often free), easy to implement, and require limited technology skills, is covered. Multimedia items that can be easily implemented in the college classroom include animation, slideshows, blogging, instant messaging, podcasting, and video on demand.  Multimedia, which uses the Internet as its transfer mechanism, can be an effective method of creating a dynamic college classroom experience
