Study Notes
Network Fundamentals
- Network devices: repeaters, bridges, routers (all of the mentioned)
Network Layer Functions
- Congestion control is optional
- Forwarding is a required function
- Routing is a required function
Transparent Bridge Functions
- Learns where stations are attached to the LAN
- Forwards frames from one LAN to another
- Prevents loops in the topology (all of the mentioned)
IP Network Layer Services
- Offers best-effort connectionless service
- Does not offer connection-oriented reliable stream service or connection-oriented transfer of packets with delay guarantee
Network Layer Complexity
- Reasons for complexity: addressing and routing challenges, requiring coordinated actions of multiple, geographically distributed network elements
End-to-End Functions
- Best implemented at a lower level than at a higher level (True)
Essential Network Functions
- Link layer is an essential network function
OSI Model and TCP/IP Model
- In OSI model, the 5th layer to receive data is the Session layer
- In TCP/IP model, the 5th layer to receive data is the Application layer
Application Layer
- Implemented in end systems
- Provides the interface between applications and the network
- Enables users to send and receive data across shared or public networks
Transport Layer
- Implemented in end systems
- Handles process-to-process delivery of packets through ports
