Unit I Summary and Checklist

Lesson 6 of 34 in the free High Speed Networks notes on Siksha Sarovar, written by Rohit Jangra.

Unit I Key Takeaways

  • Frame Relay simplified WAN networking by removing hop-by-hop error correction.
  • ATM introduced a rigid but highly scalable cell-based architecture for multimedia traffic.
  • Ethernet evolved from a shared medium to a switched, full-duplex high-speed technology.
  • Standard Wi-Fi uses CSMA/CA to manage the shared airwaves, with 802.11ax/be pushing the theoretical limits of wireless throughput.
  • Fibre Channel remains the gold standard for high-reliability storage networking in data centers.

--- Unit I Checklist:

  • [x] Differentiate between Packet Switching (Frame Relay) and Cell Switching (ATM).
  • [x] List the three layers of the ATM protocol reference model.
  • [x] Explain the function of VPI and VCI in ATM cell routing.
  • [x] Define the five bytes of an ATM UNI cell header.
  • [x] Identify the key difference between 802.11 BSS and ESS.
  • [x] Describe the RTS/CTS mechanism and why it is used.
  • [x] Compare the service categories for ATM Adaptation Layers (AAL1, AAL2, AAL5).
  • [x] Explain the transition from Half-Duplex to Full-Duplex in Ethernet's history.
  • [x] List the Fibre Channel protocol layers (FC-0 to FC-4).
