# Example 1: Suppose you are using PPP over Ethernet (DSL)

# the first you can use for voice over IP traffic,

# first, before any other traffic. A single VOIP stream,
# depending upon codecs, after encapsulation, can take up to
# 80kbps on a PPOE/DSL link, so we pad a little bit just in
# case. (TOS byte values 0xb8 and 0x68 are DiffServ classes
