Study Notes
Service Primitives
- Six service primitives exist to facilitate connection-oriented services in computer networks.
- Acknowledged datagrams are utilized for interaction between clients and servers.
Relationship of Services to Protocols
- Services operate independently and do not dictate how data is transferred; protocols govern the methods used to achieve these services.
Reference Models
- OSI (Open Systems Interconnection) and TCP/IP (Transmission Control Protocol/Internet Protocol) reference models serve as foundational structures in networking.
- Each model comprises specific layers to improve functionality and abstraction in networking operations.
- Comparisons reveal strengths and weaknesses between OSI and TCP/IP models.
OSI Reference Model
- Composed of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
- Each layer is designed for distinct functionalities, aiming to minimize information flow between layers.
- International standards influence the development of layers.
TCP/IP Reference Model
- Consists of four layers: Link, Internet, Transport, and Application.
- Protocols relevant to the TCP/IP model are studied within the context of these layers.
Comparison of OSI and TCP/IP Models
- Central concepts in the OSI model include services, interfaces, and protocols.
- Each model differs in structure and flexibility.
Critique of OSI Model and Protocols
- Criticisms of the OSI model include poor timing, outdated technology, ineffective implementations, and political issues.
Example Networks
- Significant networks include the Internet, ARPANET, NSFNET, third-generation mobile phone networks, Wireless LANs (802.11), RFID, and sensor networks.
ARPANET Development
- Initially designed from the telephone system structure; the design proposed a distributed switching system.
- The ARPANET experienced growth from December 1969 through September 1972, marking significant milestones in networking evolution.
NSFNET
- In 1988, NSFNET served as a major backbone for network connectivity, reinforcing the reach of interconnections.
Key Terms in Networking
- Important terms include packets (small data units), packet switching (data transmission method), routing (determining data paths), datagrams (self-contained data packets), and virtual circuits (logical connections between nodes).
Network Software
- Involves protocol hierarchies and the design issues tied to different service types, focusing on the distinction between connection-oriented and connectionless services.
- The relationship between service primitives and network protocols is crucial for establishing efficient communication routes.
