ERVC:
Efficient utilization of the capacity, since it is used on a demand basis.Lossless communication.
Avoids the wasteful repetition of the set-up phase ("reservation-ahead").
Simple implementation using list structure.
SDVC:
Minimal pre-transmission delay (no end-to-end reservations).Efficient utilization of bandwidth (deflections are rare).
Lossless communication
Packet resequencing easier than in packet-by-packet deflection schemes.
Both protocols deal only with constant-rate traffic (since buffer space is limited).
