Isu Quality of Service (QoS)
  • Kekurangan Bandwidth
  • Delay terlalu lama.
  • Jitter / Variasi delay.

49
QoS
  • Resource Reservation Protocol (RSVP)
  • Real Time Protocol (RTP)
  • Compressed Real Time Protocol (CRTP)
  • Traffic Shaping
  • Queuing Custom Queuing, Weighted Fair Queuing.
  • Congestion Control Random Early Detection.
  • Effisiensi Jaringan link fragmentation
    interleaving.
