http://www.faqs.org/rfcs/rfc2050.html
. See also DHCP.
Subnet Mask 32-bit binary number that filters an IP address to reveal what part identifies the
network and
what part identifies the host. The number of subnet mask bits that are
set to 1 indicates how many leading bits of the IP address identify the network. The
number of subnet mask bits that are set 0 indicate how many trailing bits of the IP
address identify the host.
Subscriber Module Customer premises equipment (CPE) device that extends network or Internet
services by communication with an Access Point Module or an Access Point cluster.
Sustained Data
Rate
Preset rate limit of data transfer.
Switch Network element that uses the port that is associated with the physical address of
another to pass data to only the intended recipient. Compare to Bridge and Router.
