Network Management |
Management of functions such as operations, adminstration, maintenance, and provisioning of systems on a network by using various activities, methods, procedures, and tools. |
|
|
Operation |
Deals with procedures to allow smooth running of the network and monitoring network to spot problems. |
|
|
Administration |
Keeping track of the assignment and utilization of devices on the network. |
|
|
Maintenance |
Repairing and upgrading network components, and making sure devices are running optimally. |
|
|
Provisioning |
Assigns resources to support a service. |
|
|
SNMP |
Simple network management protocol, layer 7, used to collect information from network devices for diagnostic and maintenance purposes. |

Throughput Testers |
Software tools that you can use to measure network throughput and capacity. |
|
|
Status monitoring |
Used to gather data related to status of network. Ex. Ping, nslookup |
|
|
Traffic monitoring |
Used to gather related data about traffic generated on network. Ex. Iptrace |
|
|
Route monitoring |
Used to trace route taken by packets. Ex. Tracert, arp |
|
|
Fault Tolerance |
Networks ability to withstand a foreseeable componet failure and continue to provide acceptable service. |
|
|
Configuration Management |
Process of setting up and changing the configuration of the network and components. |
|
|
QoS |
Quality of service is a set of parameters that controls the quality provided to different types of network traffic. |
|
|
Parameters that effect QoS on network: |
Bandwidth, latency, jitter, packet loss, echo. |
|
|
Traffic shaping |
Bandwidth shaping is a mechanism in QoS for introducing some amount of delay in traffic that exceeds the defined rate. Does not drop packets, implemented on only outbound interfaces. |
|
|
Traffic policing |
Governing flow of packets to conform to standards. Packets not conforming are dropper or marked at lower value. |
|
|
Packer shapers |
Traffic shaper, delays metered traffic so that each packet complies with the relevant traffic contract. |
|
|
Load balancing |
Dividing traffic to 2 or more servers, so traffic is distributed among the servers. |
|
|
High availability |
Expresses how close devices approach the goal of providing data 100% of the time with high performance. |
|
|
Caching engines |
Stores, indexes data to provide faster response requests for data. Retrieve data and store until it is requested. |
|
|
What network setting would you configure to ensure VoIP traffic is free of jitters? |
