Environmental Requirements in the WAN
LANs that are linked over WANs and share the same VoIP functionality must meet the following
minimum requirements:
● Each LAN must each be connected to the Internet via xDSL with a fixed IP address.
● QoS support – IEEE 802.1p, DiffServ (RFC 2474) or ToS (RFC 791) – over the entire con-
nection
● The bandwidth required for the calls must always be available in both directions, to the net-
work and to the user.
● Not more than 50 msec delay in one direction (One Way Delay) Not more than 150 msec
total delay
● Not more than 3% packet loss
● Not more than 3% error rate
● Not more than 10% jitter
● As little broadcast and multicast traffic in the network as possible. If necessary this can be
achieved by structuring the network – using VPN, for instance – with Layer 3 switches and
routers, or with Layer 2 switches that recognize multicasting.
● Not more than 40% network load (without VoIP traffic)
● Less than 40 broadcast packets per second if possible
