Then we will cover IPv4 addressing: IPv4 address classes, static vs. dynamic addresses and DHCP, public and private addresses and NAT. Then we’ll review IPv6, and how IPv6 addresses are allocated and assigned, and types of IPv6 addresses.

14. MPLS and Carrier Networks
IP packets will be used to carry everything, including phone calls and television. But IP in itself does not include any Quality of Service (QoS) mechanism, no way to prioritize or manage traffic. This is implemented with MPLS. In this chapter, you’ll learn the basics of carrier packet networks, identifying Provider Edge (PE), Customer Edge (CE), access and core, and the important concept of a Service Level Agreement. Then you’ll gain a practical understanding of the purpose and functioning of MPLS, virtual circuits and traffic classes, previous methods Frame Relay and ATM, then MPLS and how it is used to implement business customer services, differentiated services and Class of Service (CoS), service integration and traffic aggregation in the core.

PART 1: THE BIG PICTURE

1. FUNDAMENTALS OF VOIP
We will start with the fundamentals of Voice over IP: the basics of communicating voice in IP packets, demystifying the jargon and buzzwords and explaining in plain English the components of a VoIP telephone system like soft switches and gateways, what each does, along with protocols like SIP. 2. FUNDAMENTALS OF TELECOM
As one of the main uses of VoIP is to make telephone calls, having a solid base in the fundamentals of telecom and the telephone network is essential. You will fill in gaps and learn how the telephone network is structured, who does what, how it’s done, and how connections are made. We’ll demystify loops and trunks, COs and wire centers, analog, the voiceband, digital, DS0 channels vs. packets, switched access and toll centers, and understand how phone companies, cable companies, wireless carriers and internet VoIP carriers connect.
3. FUNDAMENTALS OF DATACOM
In this module, you will learn the basics of data packet networks – now used to carry VoIP phone calls along with Internet traffic, video, business data and everything else. We’ll start with circuits, LANs and WANs, then understand the fundamental ideas of how routers relay packets from one circuit to another to reach the far end, and how this is accomplished with addresses and packets carried in frames.

4. THE MANY DIFFERENT IMPLEMENTATIONS OF VOIP
“Voice over IP” can happen in many different ways. One by one, we’ll review the many flavors of VoIP, comparing and contrasting the various implementations and architecture choices. Starting with Internet telephony, we will then understand VoIP at the telephone company, how VoIP connects to older systems, and new services like SIP Trunking. We will compare and contrast choices for a VoIP system: getting it from the phone company; buying a call manager / softswitch; renting a Hosted PBX; and cloud solutions. You’ll gain the knowledge to confidently differentiate VoIP architectures and discuss pros and cons of options.


Class Exercise: Trace a VoIP Call End-to-End Internet to Cellphone
We’ll establish a phone call from a VoIP client on a computer in the classroom via WiFi and the Internet to a cellphone in the classroom, and identify where the voice packets travel, from one circuit, device, and company to the next, end-to-end between the two sets of microphones and speakers. This will cement your understanding of VoIP telephone calls, the telecom business and how everything is connected.

PART 2: VOIP AND SIP NUTS AND BOLTS

5. PACKETIZED VOICE AND SOUND QUALITY
In this module, you’ll learn what exactly packetized voice is, how it happens, and the various standards in use. You’ll learn about the factors affecting sound quality, and how packets actually get “lost” in a network. We’ll listen to sound clips of impairments, and provide you with a practical checklist of tips and recommendations for ensuring success.
Class Activity: Sound Clips with Impairments
Listening to sound clips, you’ll hear the effect of different levels of uncorrected delay, jitter and packet loss, and understand how the quality of the reproduced speech at the far end is affected.

6. SIP AND SOFTSWITCHES
SIP is the open, standard protocol for setting up Voice over IP telephone calls. All VoIP systems that purport to be “compatible” or “standards-based” must implement the Session Initiation Protocol. SIP defines the procedure and messages to set up a phone call – or any other kind of communication. In this chapter, you’ll learn what exactly setting up a VoIP telephone call entails, understand what SIP is, how it works, demystify jargon like proxy server, registration and location server, understand how SIP fits in with softswitches and call managers, and trace the establishment of an IP phone call step by step. At the end of this, you’ll understand how VoIP phone calls are set up – maybe worth attending the course all by itself!

7. SIP TRUNKING AND CARRIER CONNECTIONS
This chapter is all about connecting an in-building business VoIP phone system to the world. First, we’ll understand how connections used to be implemented with PBX trunks and ISDN PRI service. Then we’ll see how a gateway connects a modern VoIP system onto PBX trunks, and most importantly, how SIP Trunking replaces PBX trunks with a lower-cost and more flexible solution. Many big organizations have an existing data network, implemented as a VPN by a carrier. We’ll look at the advantages and disadvantages of using the “data” VPN, or the Internet, compared to SIP Trunking, and finish off with a practical checklist of features and technologies to require when choosing a carrier.

Group Exercise: Case Study – Saving Money Migrating Five-State Company to VoIP

To cement your understanding of VoIP phone systems and carrier services, and even gain valuable insight into your own situation, you’ll work in a group to come up with the best solution for a company with 5,000 people in five states to migrate from PBX trunks to VoIP. The winners will be the ones who save the most money. Bonus points for saving money and providing useful new features!

Bonus! All students receive a large printed poster explaining VoIP call quality metrics and thresholds. Besides being cool cubicle wall covering, it provides a lot of useful information!

PART 3: THE NETWORK

9. ORGANIZING THE DISCUSSION
Much of the last day is devoted to understanding the modern IP-based telecom network. To get started, we’ll organize the discussion using the OSI 7-Layer Reference Model, explaining what a layer is, and what the layers are, and giving examples of protocols like TCP and IP and where they fit.

10. ETHERNET ON COPPER, FIBER AND WIRELESS
Ethernet and its MAC frames are the building blocks of all new telecom networks, both in-building and between buildings. A VoIP phone plugs into a copper Ethernet LAN cable, or uses an Ethernet Wireless LAN to connect to the network. The network itself is built with point-to-point circuits conforming to the Optical Ethernet standard connecting equipment in different locations with fiber. In this module, you will learn the basic principles of Ethernet and LANs, the crucial concepts of MAC addresses, MAC frames and broadcast domains, how devices connect via LAN switches, and how VLANs separate groups of users.

11. IP ADDRESSES AND ROUTERS
Routers implement the network by relaying packets from one circuit to another. Determining which circuit to relay the packet to is the routing part of the story. In this module, you will fill in gaps, learn how IPv4 addresses are organized and how they are used to route packets between telephones during a VoIP phone call. We’ll cover DHCP, static vs. dynamic addresses, public vs. private addresses, NAT and how ARP relates Ethernet to IP. To be ready for the future, we’ll finish with a review of the IPv6 address structure and usage.

Class Exercise: IP and MAC Addresses
Using the Windows interface, we’ll determine the current MAC and IP Addresses of a classroom computer, and the private and public IP addresses of the Edge Router and NAT it’s connected to. This will help visualize what IP addresses are, and covers two of the questions on the Final Exam.

12. TCP, UDP AND PORTS
You will learn that IP does not come with any guarantees. There is no guarantee a packet will be delivered. Nada. To be sure a packet gets delivered, we use TCP or UDP. Plus, we’ll demystify a second piece of information that sneaks in with TCP and UDP: ID of the computer program you want to talk to. This ID is called the port number.

13. IP NETWORK QUALITY: COS, QOS, MPLS AND SLAs
You will also learn that IP networks do not come with any performance guarantees: when the next packet will be transmitted, and how often that might happen… but banks, other carriers, government and other large organizations need guarantees. Guaranteed IP packet data communications between locations is called a VPN or MPLS service. We’ll demystify and sort out quality of service, Class of Service (CoS), Service Level Agreement (SLA) and MPLS.
Group Exercise: Open-book group collaboration final exam: Full VoIP Protocol Stack
At this point is the in-class Final Exam. The good news: it is done in groups, open book.
Determine the full VoIP protocol stack, identifying information needed at each of the 7 layers for a VoIP
– VoIP telephone call. Exam format: fill in the blanks on a diagram of a protocol stack.
This requires understanding all of the pieces involved in moving a telephone call in IP packets from one person to another, touching on everything covered in the course.
Everyone participating in the in-class group-collaboration open-book final exam will receive a course completion certificate. Those who write the optional online CVA exam after the class will also receive TCO Certified VoIP Analyst certification.

PART 4: PROJECT MANAGEMENT


14. VOIP MIGRATION PROJECT STEPS, TIPS AND TRICKS
The final module is a template for managing a VoIP project, with detailed checklists in the course book. Going through the template, you’ll learn how to do it the “right” way, from analyzing requirements to running trials, evaluating and selecting a vendor, rollout, acceptance testing and more. This project management guide is packed with practical tips and checklists to put to immediate use. If you are about to embark on a VoIP deployment, this might well be worth the price of the course all on its own!
