Advantages Disadvantages
FIFO 1
• No need to configure, easy to use
• Easy to operate, low delay
• All packets are treated equally. The
available bandwidth, delay and
drop probability are determined by
the arrival order of packets.
• No restriction on the incooperative
data sources (that is, flows without
any flow control mechanism, UDP for
example), resulting in bandwidth loss
of cooperative data sources such as
TCP.
• No delay guarantee for
time-sensitive real-time applications,
such as VoIP
