In this comprehensive course, you’ll build a solid base of knowledge in networking fundamentals. We'll begin with serial and parallel point-to-point circuits, then identify the need for link addressing and access control on circuits with multiple stations, LANs and how the stations on a LAN form a broadcast domain. We'll understand the need for framing and error control to transmit data, and how this is implemented with MAC frames and MAC addresses.
Then we'll define a network, and how it is implemented with WAN circuits, routers and IP network addresses as the basis of routing decisions. Next, we'll understand how carrier packet networks are used to implement WAN circuits, the relationship between packets and frames, the IP address on the packet and how the MAC address changes as the packet is forwarded across a network. We'll finish with an overview of IPv4 and IPv6 packet formats, the need for a transport protocol and how TCP is used for reliability, and UDP is used for streaming, and what port numbers are and how they are used. The course is completed with an introduction to MPLS, the traffic management system used on the core of big networks.

Course Outline
1. Point-to-Point Circuits: Serial and Parallel
How serial is a type of Time-Division Multiplexing, and implemented in parallel to increase capacity.
2. Multidrop Circuits: Point to Multipoint
Master-slave or "unbalanced" communication links, and the need for link addressing and access control when there are multiple stations on a circuit.
3. LANs and Broadcast Domains
"Balanced" communication links, where all stations are equal. How the computers connected by a LAN form a broadcast domain. How serial is a type of Time-Division Multiplexing, and implemented in parallel to increase capacity.
4. Framing and Error Control Requirements
Why framing and error control are needed to transmit data. We'll briefly discuss the old "asynchronous" start-stop-parity method, what asynchronous really means, and areas for improvement.
5. Frames & MAC Addresses
The method used for framing, link addressing and error control on the customer premise LAN, on the access circuit, and in the carrier network core.
6. Networks, Routers and IP Addresses
The definition of a network: the need to make route decisions, by a router, using IP addresses as the basis of making route decisions. Identification of WAN services as the expensive part of the story.
7. Carrier Packet Network Services
Using a carrier packet network, whether it is the Internet or carefully-controlled carrier circuits, as the most cost-effective and flexible way of implementing WAN circuits.
8. Packets vs. Frames
How packets are carried in frames. The relationship between the MAC address on a frame and the IP address on a packet. Does one packet fit exactly inside one frame? What protocol segments a big file into small packets?
9. IP Address vs. MAC Address: SFO-NYC via AT&T
Understanding the IP address on a packet vs. the MAC address on a frame, and how it changes from one hop to the next across a network.
10. IP Packets
An overview of the structure of IP packets, and both the IPv4 and IPv6 packet headers.
11. TCP, UDP and Port Numbers
Why a transport protocol is required for communication across an unreliable IP packet network. How TCP works, and why UDP is used for live phone calls. What port numbers are and how they are used.
12. MPLS Labels
A brief introduction to MPLS, and how it is used to label packets as belonging to a traffic class for management of traffic in the network core.

Encryption plays a key role in many of today's telecom and network technologies and services. We'll begin by understanding symmetric key encryption vs. asymmetric key encryption, public key encryption (PKI) and private key encryption. Then we'll explore implementations, including digital certificates for secure web browsing, digital signatures for authentication, IP VPNs and SD-WANs for secure point-to-point Internet communications, country-spoofing VPNs, and basics of anonymizer VPNs and the Dark Web.
Course Lessons
1. Introduction - Encryption: Certificates, VPNs, SD-WANs and the Dark Web
2. Public Key and Private Key Encryption
3. Digital Certificates, SSL and TLS
4. IP VPN Tunnels
5. SD-WANs
6. Country-Spoofing VPN Service
7. Anonymizer VPN Service: Tor Virtual Circuits
8. The Dark Web

Course Outline
1. Introduction - Encryption: Certificates, VPNs, SD-WANs and the Dark Web
2. Public Key and Private Key Encryption
The fundamentals: symmetric encryption, and asymmetric encryption. Secret keys, public keys and private keys. Secure communications and digital signatures. AES and DES. RSA encryption and Elliptic-Curve Diffie-Hellman Ephemeral cryptography.
3. Digital Certificates, SSL and TLS
The purpose of a digital certificate and the server identity key. Certificate issuance and installation on a server. Downloading the certificate to a browser. Using the public key in the certificate to authenticate Diffie-Hellman secret session key establishment for TLS and encryption of HTTP client-server messages. TLS vs SSH. https.
4. IP VPNs and Tunnels
"Virtual" in Virtual Private Network means that it appears to the user there are dedicated point-to-point circuits between buildings, but in reality, there are many users' packets interspersed on the physical circuits used for the connections, which are usually over the Internet. We'll cover IPsec, a collection of standards, and how they are used to implement encrypted tunnels for secure communications over the Internet, and how that compares to MPLS VPNs and TLS.
5. SD-WANs
A Software-Defined Wide Area Network (SD-WAN) implements communications with information confidentiality between multiple locations of an organization, in IP packets, using pairwise IP VPN tunnels over the Internet. We'll cover fundamentals, and practical considerations regarding supply and management of SD-WAN services.
6. Country-Spoofing VPN Service
How a Network Address Translator (NAT) is deployed by a country-spoofing service provider in a target country to make it appear that packets originate from that country; and why this service is not free.
7. Anonymizer VPN Service: Tor Virtual Circuits
How anonymous communication of HTTP client-server messages is accomplished using three relays with encryption or decryption at each step to implement a Tor virtual circuit to the third relay, which opens an ordinary HTTP over TLS over TCP connection to the server. We do a slightly deep dive on the mechanics of the Tor virutal circuit as an effective method of reinforcing knowledge of how secret keys are created and used.
8. The Dark Web
Finishing with an interesting topic, that also illustrates how asymmetrical keys with their public component and private component, and secret symmetric keys are used to connect a browser to a web server without the IP address of the server ever being known, which is how the web server is kept "dark". What the dark web is, how it operates, how dark web sites are advertised, how Ross Ulbricht ran the Etsy of illegal goods, and how he was caught.
