In this article we will discuss IP SLA Concepts, will make brief discussion on IP SLA Concepts, In last article we discuss about Broadcast Domains.
IP SLA (Internet protocol service level agreement) is a feature of the Cisco Internetwork Operating System (Cisco IOS) that allows an IT professional to collect information about network performance in real time.
Network administrators must be proactive and continually monitor and test the network. The goal is to discover a network failure as early as possible. A useful tool for this task is the Cisco IOS IP Service Level Agreement (SLA).
IP SLAs use generated traffic to measure network performance between two networking devices, multiple network locations, or across multiple network paths. In the example in the figure, R1 is the IP SLA source that monitors the connection to the DNS server by periodically sending ICMP requests to the server.
Network engineers use IP SLAs to simulate network data and IP services to collect network performance information in real time. Performance monitoring can be done anytime, anywhere, without deploying a physical probe.
Measurements provided by the various IP SLA operations can be used for troubleshooting networks by providing consistent, reliable measurements that immediately identify problems and save troubleshooting time.
There are additional benefits for using IP SLAs:
Service-level agreement monitoring, measurement, and verification
Network performance monitoring to provide continuous, reliable, and predictable measurements to measure the jitter, latency, or packet loss in the network
IP service network health assessment to verify that the existing QoS is sufficient for new IP services
Edge-to-edge network availability monitoring for proactive connectivity verification of network resources
Multiple IP SLA operations can be running on the network, or on a device, at any time. IP SLA information can be displayed using CLI commands or through SNMP.
I am Hamza arif, and i am excited to learn new things, i am well focused for my work and always try to explore new things. My graduate is in BS (Telecom) and i am expert in Networks and working on new technology is my passion i work a lot on AI (Artificial Intelligence) Augmented Reality and many other projects.
