| 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  | 
| 
 | 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 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  | 
| 
 | 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. |
