Study Notes
Communication Elements
- All communication methods involve three common elements: source (sender), destination (receiver), and channel (media).
- Effective communication is governed by protocols, which include identified sender and receiver, common language and grammar, speed/timing of delivery, and acknowledgment requirements.
Protocols in Network Communications
- Protocols define message encoding, delivery options (Unicast, Multicast, Broadcast), formatting (identifying sender and receiver), timing (Access Method, Flow Control), and size restrictions leading to message segmentation.
- Communication messages are initially converted into bits, which are encoded into signals (sounds, light waves, or electrical impulses) suitable for the network medium.
Message Transmission and Encapsulation
- Messages are encapsulated in frames which contain addressing information for source and destination, akin to placing a letter in an addressed envelope.
- Each frame is treated as an individual message unit, with a receiving host responsible for reconstructing the original message from these frames.
Flow Control and Access Method
- Hosts employ flow control to avoid overwhelming the recipient and negotiate timing.
- Collisions must be managed, requiring rules for when to send messages and how to react when they occur.
Networking Protocols
- Protocol suites are implemented in software and hardware, featuring layered views where each layer depends on the functionality of the lower layers.
- Common protocols include:
- HTTP (web communication)
- TCP (manages data segments)
- IP (encapsulates segments into packets)
- Ethernet (facilitates data transmission over a network).
Encapsulation Procedure
- Data sent from a web server to a client follows this procedure:
- HTML page sent through the HTTP protocol to the transport layer.
- The transport layer segments the data, adding IP source and destination addresses.
- Ethernet information is added creating the final data link frame.
Internet Governance Organizations
- Internet Society (ISOC): Advocates for open Internet development worldwide.
- Internet Architecture Board (IAB): Manages and develops Internet standards.
- Internet Engineering Task Force (IETF): Develops and maintains Internet and TCP/IP technologies.
- ICANN: Coordinates IP address allocation and domain name management.
- IANA: Manages IP address allocation and protocol identifiers.
- IEEE: Focuses on technological innovation and networking standards.
- ITU-T: Establishes standards for broadband communications and video compression.
Benefits of Layered Model
- Streamlines protocol design, allowing each layer to have defined functions.
- Encourages competition as products from various vendors can interoperate.
- Prevents changes in one layer from disrupting others.
TCP/IP Protocol Model
- Established in the early 1970s as an open standard for internetwork communication.
- Data streams are divided into smaller segments for transmission, known as multiplexing, facilitating simultaneous conversations.
- Encapsulation occurs from application layer down to physical layer, with each layer creating a Protocol Data Unit (PDU):
- Data (application layer)
- Segment (transport layer)
- Packet (network layer)
- Frame (data link layer)
- Bits (physical layer).
Encapsulation and De-encapsulation Process
- Encapsulation goes from data segmentation to adding headers at each layer down to the physical layer.
- De-encapsulation occurs in reverse order upon reception, removing headers sequentially to retrieve the original data.
Addressing in Networking
- Source and destination IP addresses identify the original sender and final receiver.
- Data link addressing, using MAC addresses, facilitates direct delivery within a local network.
- Communication to remote networks involves routing through gateways, where new data link information is appended for forwarding.
