Weighted Fair Queuing. A flow-based queuing algorithm that does two things
simultaneously: It schedules interactive traffic to the front of the queue to reduce
response time, and it fairly shares the remaining bandwidth between high
bandwidth flows.
A bit mask used in access rules, IPSec rules, and NAT rules to specify which
portions of the packet's IP address must match the IP address in the rule. A
wildcard mask contains 32 bits, the same number of bits in an IP address. A
wildcard bit value of 0 specifies that the bit in that same position of the packet's
IP address must match the bit in the IP address in the rule. A value of 1 specifies
that the corresponding bit in the packet's IP address can be either 1 or 0, that is,
that the rule "doesn't care" what the value of the bit is. A wildcard mask of
0.0.0.0 specifies that all 32 bits in the packet's IP address must match the IP
address in the rule. A wildcard mask of 0.0.255.0 specifies that the first 16 bits,
and the last 8 bits must match, but that the third octet can be any value. If the IP
address in a rule is 10.28.15.0, and the mask is 0.0.255.0, the IP address
10.28.88.0 would match the IP address in the rule, and the IP address
10.28.15.55 would not match.
Windows Internet Naming Service. A Windows system that determines the IP
address associated with a particular network computer.
Wi-Fi Multimedia. An IEEE 802.11e Quality of Service (QoS) draft standard.
WMM compliant equipment is designed to improve the user experience for
audio, video, and voice applications over a Wi-Fi wireless connection.
Weighted Random Early Detection. A queueing method that ensures that
high-precedence traffic has lower loss rates than other traffic during times of
congestion.
A digital certificate standard, specifying certificate structure. Main fields are ID,
subject field, validity dates, public key, and CA signature.
A digital certificate that is structured according to the X.509 guidelines.
