S

server

In a client/server architecture, a dedicated computer that supplies files or services such as file transfer,

 

remote login, or printing to clients.

 

scope

The set of IP addresses that a DHCP server can lease to clients.

service provider

A company providing cable data services to subscribers.

 

SID

A service ID is a unique 14-bit identifier the CMTS assigns to a cable modem or gateway that

 

identifies the traffic type it carries (for example, data or voice). The SID provides the basis for the

 

CMTS to allocate bandwidth to the cable modem and implement CoS.

SDU

service data unit

 

SME

small and medium enterprise

 

SMTP

Simple Mail Transfer Protocol is a standard Internet protocol for transferring e-mail.

SNMP

Simple Network Management Protocol is a standard to monitor and manage networks and network

 

devices. Data is exchanged using PDU messages.

 

SOHO

small office home office

 

spectrum

A specified range of frequencies used for transmission of electromagnetic signals.

spectrum

An allocation of portions of the available electromagnetic spectrum for specific services, such as AM,

allocation

FM, or personal communications.

 

splitter

A device that divides the signal from an input cable between two or more cables.

stateful

A type of firewall that tracks each connection traversing all firewall interfaces to ensure validity. In

inspection

addition to examining the source and destination in the packet header based on static rules, a stateful

 

inspection firewall:

 

 

Examines packet headers on context established by previous packets that traversed the firewall

 

Monitors the connection state and saves it in a table

 

 

Closes ports until a connection to a specific port is requested

 

May examine the packet contents up through the application layer to determine more than just the

 

source and destination

 

 

A stateful-inspection firewall is more advanced than a static filter firewall.

static filter

A type of firewall that examines the source and destination in the packet header based on

 

administrator-defined rules only.

 

static IP

An IP address that is permanently assigned to a host. Normally, a static IP address must be assigned

address

manually. The opposite of dynamic IP address.

 

static route

A manually-defined route.

 

station

IEEE 802.11b term for wireless client.

 

subscriber

A home or office user who accesses television, data, or other services from a cable provider.

subnet mask

A bit mask that is logically ANDed with the destination IP address of a packet to determine the network

 

address. A router routes packets using the network address.

subnetwork

A part of a network; commonly abbreviated “subnet.” When subnetting is used, the host portion of the

 

IP address is divided into a subnet and host number. Hosts and routers use the subnet mask to

 

identify the bits used for the network and subnet number.
