Components of End-to-End Delay
- Main components of end-to-end delay include:
- Transmission Delay: Time taken to push all bits of a packet into the wire.
- Propagation Delay: Time for a signal to travel from the sender to the receiver.
- Queuing Delay: Time waiting in a queue before being transmitted.
- Processing Delay: Time taken to process the packet header and forward it.
Focus on Network Core
- The primary focus regarding the network core highlights the infrastructure and protocols critical for routing data efficiently across the networks.
'Nuts and Bolts' View of the Internet
- The 'nuts and bolts' view of the Internet entails a detailed examination of the fundamental hardware and software components that enable Internet functionality and connectivity.
