Networking Technologies

This 2-Day Overview on LAN / WAN Networking and Systems introduces the basic fundamentals of Networking with LANs and WANs and includes information on the key elements in a Modern Networking System. Delegates will be introduced to the function and workings of Modern Networks including an Introduction to Cloud Computing.

The Internet Protocol Suite, commonly known as TCP/IP, forms the basis for the Internet and the next generation of networking and telecommunications services.  Not only is it being used for pure data services such as Electronic Mail and Web-Based services but it is now also used as the core for mobile phone networks and Next Generation Services. 

It is now important for any staff involved in the transportation of data over networks to understand how the many hardware and software elements in a network interact and compliment each other in order to provide a secure environment for the storage and transportation of data.

On completion of this course delegates will be able to:

-          Explain the function of a Data Network.

-          Differentiate between LAN and WAN services.

-          Have an appreciation of Secure Wireless Network Technology.

-          Understand the fundamentals of Client / Server Operation.

-          Understand the terms ‘Thick and Thin Clients.

-          Have an appreciation of Remote Access Technologies (Risks and Mitigation).

-          Explain the purpose and function of a Firewall.

-          Have an appreciation Network Security Features.

-          Appreciate Hacking and its prevention

-          Understand the purpose of Cloud Networks.

-          Understand the basic of Storage Media and RAID Systems.

-          Describe Virtual Server Technology.

-          Explain the Term ‘Blade Technology’.

-          Describe Backup Power Systems and Data Systems

-          Be familiar with some common Monitoring Tools.

Voice over IP with SIP

Introduction to Voice over IP (VoIP) and Session Initiation Protocol (SIP)

This course has been designed to provide delegates with knowledge of the fundamental principles of VoIP (Voice over Internet Protocol). The open standard Session Initiation Protocol (SIP) is described, its function explained and how it fits in with existing network models. A comparison is also made with the ITU H.323 standard. Vendor Specific systems such as Cisco CallManager is included in the course as well as reference to Asterisk Open Source systems.

The course focuses on the theoretical and practical aspects of VoIP, concentrating on SIP, and is intended as an introduction to VoIP software and hardware. Following delivery of the course, the delegates will have a fundamental knowledge of the subject, which will stand them in good stead for further advanced Voice over IP training. This course includes practical modules which allow students to configure VoIP Phones, Softphones, a software IP PBX, and to size a VoIP solution

Prerequisites

·         Some basic knowledge of networking and voice.

Learning Objectives

At the end of this class, participants will be able to:

·         Understand the reasons for the development of voice over data networks.

·         Have an appreciation of factors affecting voice quality.

·         Understand the IETF protocols developed to allow real-time media to be transported across data networks.

·         Determine the function of the real-time protocols and where in the TCP/IP protocol stack they operate.  

·         Understand the basic functions of the IETF Session Initiation Protocol and compare it’s operation to that of H.323.

·         Have a basic understanding of Cisco VoIP hardware.

·         Have a basic understanding of Asterisk open source architecture.

·         Understand the importance of Quality of Service when setting up VoIP systems.

·         Understand the fundamentals of IP Multicasting.

·         Analyze SIP callflows and understand the basic format of SIP messages.

·         Set up a simple Site-to-Site SIP solution using an IP PBX.

Who Should Attend

·         Network technicians, Network Engineers,Technical Managers and Support Staff who need a basic technical  understanding off Voice over IP with SIP.

 Course Outline

·         Introduction to Voice over Internet Protocol.

·         Voice Quality Issues.

·         Protocols – Transport and Network Layers

·         Protocols – Application Layer

·         How Routing Protocols fit in

·         SIP – Session Initiation Protocol.

·         Comparison of SIP with H.323 standard.
