ATM cell-based Network(cont.)

• Each cell is of fixed length
  • Simplify the switching hardware
  • Structured VLSI implementation
  • Short cell length
    • Transit delay is small
    • More segmentation and assembly
    • More header processing time
    • More overhead in link capacity
    • No link level error recovery
      • Low error rate of optical fibre
      • Some traffic does not need error recovery
