While you are connected in chat, transfer files between partners. Use a continuous ping from the host to
the eagle server to monitor network throughput. Observe the response time before and during the file
transfer. Write a brief description of the network response time—during file transfers and without file
Lab 1.6.1: Using Collaboration Tools—IRC and IM Topology Diagram Learning Objectives Upon completion of this lab, you will be able to: Define Internet Relay Chat (IRC) and Instant Messaging (IM). List several collaborative uses of IM. List several misuses and data security issues involving IM. Use IRC to demonstrate collaboration. Background E-mail permits multiple users to collaborate, share ideas, and transfer files. However, unless the user constantly monitors the e-mail account, unread e-mail may go unnoticed for a long period of time. When people have wanted immediate contact, the telephone has been the technology of choice. Unfortunately, the telephone cannot be used to transfer files. What collaborators need for communication in the human network is a tool that has the flexibility of e-mail with the responsiveness of the telephone. Internet Relay Chat (IRC) and Instant Messaging (IM) fit nicely into these requirements. Using the Internet or a private corporate network, users can easily exchange ideas and files. IMing and Chatting are both methods of real-time communication; however, they are implemented differently. Instant Messaging provides one-on-one communication with "accepted" individuals. To initiate an Instant Message, one person needs to "invite" another. The recipient of the invitation needs to know—and accept—the IM session based on the other user's screen name. IM clients allows you to have an approved list of users, often called a Buddy List. If you want to communicate with more than one person at a time, you can open additional IM windows. Each of these windows represents a two-person communication. Internet Relay Chat, on the other hand, allows multiple people to interact. Chat also provides a degree of anonymity. To start chatting, you establish a connection to a chat server and join a discussion on a particular topic. When you join, you are said to “join a room.” In the chat room, you typically create your own identity and can give as little information about yourself as you choose. While the following discussion focuses primarily on IM, a brief hands-on lab with our “model Internet cloud” will demonstrate the ease of IRC. IM requires a device providing services that allows users to communicate. This device is referred to as the Instant Messenger Server . The users on the end devices, such as a computer, use a piece of software called the Instant Messenger Client . This arrangement is called a client/server relationship.

CCNA Exploration Network Fundamentals: Living in a Network-Centric World Lab 1.6.1: Using Collaboration Tools—IRC and IM clients connect to an IM server, and the server joins clients. This relationship is called an IM network. There are many different IM networks available, each with a dedicated following of users. Popular IM networks include America On Line (AOL) Instant Messenger (AIM), Windows Live Messenger (MSN), Yahoo! Messenger, and ICQ (I Seek You). Figure 1 shows the AIM client application connected to the AIM network. Figure 1. AIM Client Features IM services have several common features: When an IM client connects to the IM network, any existing connections can be alerted through a contact list, a list of other people that you communicate with through the IM Client. File sharing between IM clients enables work collaboration. Text messaging between clients is possible, and can be logged. Some IM networks offer audio services. Newer services that some IM networks are beginning to provide include video conferencing, Voice over IP (VoIP), web conferencing, desktop sharing, and even IP radio and IPTV. Protocols Each IM network uses an agreed-upon method of communication, called a protocol. Many of the IM networks use proprietary protocols. AIM and ICQ (purchased by AOL) use the proprietary Open System for Communication in Realtime (OSCAR) protocol. Both Microsoft and Yahoo! have proprietary protocols but have partnered services for joint connectivity. Throughout this course we will learn about many different protocols. The Internet Engineering Task Force (IETF) has attempted to standardize IM protocols, notably with the Session Initialization Protocol (SIP). SIPv2 was originally defined in RFC 2543, and made obsolete by RFC 3261. As with proprietary IM protocols, there are numerous open source protocols. Some IM client applications, such as Gaim and Trillian, can differentiate between the various IM network protocols; IM servers can also incorporate this support. The IETF formalized an open standard, Jabber, based on the Extensible Messaging and Presence Protocol (EMPP). Applicable IETF references are RFC 3290 and RFC 3291. Encrypted communication is supported. All contents are Copyright © 1992–2009 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information. Page 2 of 7
