Java Developer Oriented Comparison of Communication Services Sean Leslie Ricardo Tirado
Introduction • Project Title • Self-configuration of UCM layer for CVM • Project Goal • Incorporate Google Talk and JML functionality into CVM • Apply self-configuration to UCM • Project Status • In-depth inspection and comparison of communication API • Survey Paper
Introduction • Problem • No criteria for rating communication services or their API • No comparison of JML, NCB, Skype, Google Talk/Smack • No one communication service satisfied all of our needs • Motivation • Develop criteria for comparison • Apply this criteria to JML, NCB, Skype, Google Talk/Smack • Provide Java developer oriented comparison of these four service layers
Background • Historical Brief • Communication: Essential to mankind civilization • Internet: new model • perks • Email • Instant messaging • Voice conversation
Background • Autonomic Computing • Self-configuring behavior in computing systems. • Communication Virtual Machine • Paradigm shift on the development of today’s communication applications.
Background • Communication Frameworks • Reusable partial application for communication • Implements protocols • Focus on applications top requirements • Examples • JML • Smack • Eclipse Communications Frameworks
Core Features Chat (1 to 1) Chat (Group) Contact List Audio (1 to 1) Video (1 to 1) Video (Conference) File Transfer Additional Features Scrolling Marque Text Emoticons Online Status Avatar Images Voicemail Communication Features
Presence File transfer Open source Simple Contact list 1-1 chat 1-all chat Some code must be implemented Limited features for third part clients. No streaming videos. No voice chat. No video conferencing. No file-sharing. Poorly documented Project is still in early development. Java MSN Library (JML) Pros Cons
Skype Pros Cons • Presence • Contact list • 1-1 and group chat • 1-1 Audio calls(PC-PC) • 1-1 Audio calls(PC-Land) • Voice conferencing • 1-1 Video • No file-sharing • Not open source • No Video Conferencing
Smack/Google Talk • Why use smack? • No complete Java implementation of Google Talk API • XMPP supported Cons Pros • Presence • Contact List • File transfer • Open source • 1-1 and Group chat • Audio Chat (PC-PC) • Well documented • Limited features in comparison to Google Talk • No video. http://www.igniterealtime.org/builds/smack/docs/latest/documentation/
Presence Contact List 1-1 and group chat 1-1 voice chat (PC-PC) Voice conferencing 1-1 video chat (PC-PC) Video Conferencing Network Communication Broker (NCB) Pros Cons • No file transfer • Not fully tested
Comparison (Features) • Identify the core features • Award a check for each core feature present in the API • List additional features and award a check for additional features
Comparison (Documentation) • Identify different kinds of documentation • Award a check for each form of documentation provided
Comparison (Totals) • Total each category for a side-by-side comparison
