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 | |||||
|
|
| 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 | |||||
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 | |||
static filter | A type of firewall that examines the source and destination in the packet header based on | |||||
|
|
|
| |||
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 |
|
| |||
station | IEEE 802.11b term for wireless client. |
| ||||
subscriber | A home or office user who accesses television, data, or other services from a cable service 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. | |||
switch | On an Ethernet network, a switch filters frames based on the MAC address, in a manner similar to a | |||||
|
|
| bridge. A switch is more advanced because it can connect more than two segments. | |||
