Glossary

MIB

Management Information Base. Database of network management

 

information that is used and maintained by a network management protocol,

 

such as SNMP or Common Management Information Protocol (CMIP). The

 

value of a MIB object can be changed or retrieved using SNMP or CMIP

 

commands, usually through a GUI network management system. MIB

 

objects are organized in a tree structure that includes public (standard) and

 

private (proprietary) branches.

NAT

Network Address Translation. Mechanism for reducing the need for globally

 

unique IP addresses. NAT allows an organization with addresses that are not

 

globally unique to connect to the Internet by translating those addresses into

 

globally routable address space. Also known as Network Address Translator.

NetFlow

A feature of some routers that allows them to categorize incoming packets

 

into flows. Because packets in a flow often can be treated in the same way,

 

this classification can be used to bypass some of the work of the router and

 

accelerate its switching operation.

network module

Type of network module.

NTP

Network Time Protocol. Protocol built on top of TCP that ensures accurate

 

local time-keeping with reference to radio and atomic clocks located on the

 

Internet. This protocol is capable of synchronizing distributed clocks within

 

milliseconds over long time periods.

PCI

Peripheral Component Interconnect. An industry local bus standard.

QoS

Quality of Service. Cisco IOS QoS technology lets complex networks control

 

and predictably service a variety of networked applications and traffic types.

RMON

Remote Monitoring. MIB agent specification described in RFC 1271 that

 

defines functions for the remote monitoring of networked devices. The

 

RMON specification provides numerous monitoring, problem detection, and

 

reporting capabilities.

Service engine

Content-networking product (hardware plus software) that accelerates

 

content delivery, ensuring maximum scalability and availability of content.

Service (or services)

Alternate term for network module with installed application software.

engine

 

service module

Standalone content engine with its own startup and run-time configurations

 

that are independent of the Cisco IOS configuration on the router.

SNMP

Simple Network Management Protocol. Network management protocol used

 

almost exclusively in TCP/IP networks. SNMP provides a means to monitor

 

and control network devices, and to manage configurations, statistics

 

collection, performance, and security. SNMPv2c supports centralized and

 

distributed network management strategies and includes improvements in the

 

Structure of Management Information (SMI), protocol operations,

 

management architecture, and security. SNMPv3 provides secure access to

 

devices by a combination of authenticating and encrypting packets over the

 

network.

SSH

Secure Shell Connection protocol is a protocol that provides a secure remote

 

connection to a router through a Transmission Control Protocol (TCP)

 

application.
