What is RPM?
• RPM is Real 3me Performance Monitoring
• RPM feature allows network operators and their customers to accurately measure the performance between two network endpoints.
• RPM sends probes to a specified target and monitor the analysed results to determine packet loss, round-‐trip 3me, and jiGer.
How dose RPM work?
• RPM allows us to perform service-‐level monitoring. • RPM is configured on a device, the device calculates network performance based on: • packet response 3me • jiGer, and packet loss
• These values are gathered by Hypertext Transfer Protocol (HTTP) GET requests, Internet Control Message Protocol (ICMP) requests, and TCP and UDP requests depending on the configura3on.
Advantages of using RPM Junos service
• Keep track on the link to end point of our provider.
• Switch path of route in the rou3ng table even that route is sta3c route or dynamic route.
• High availability on the network with internet accessing.
• No packet interrupt with black hold route.
Disadvantages of using RPM Junos service
• Spend bandwidth for probe packet use in the internet link.
• Require technical knowledge more than rou3ng and switching
• If we set the probe packet with small value, it will flex our route and use more CPU usage.
Implementing RPM service in Junos service • Scenario
Configure RPM service
• set services rpm probe ISPA test icmp-‐test target address 203.200.1.2 • set services rpm probe ISPA test icmp-‐test probe-‐count 1 • set services rpm probe ISPA test icmp-‐test probe-‐interval 1 • set services rpm probe ISPA test icmp-‐test probe-‐type icmp-‐ping • set services rpm probe ISPA test icmp-‐test test-‐interval 1 • set services rpm probe ISPA test icmp-‐test thresholds successive-‐loss 1 • set services rpm probe ISPA test icmp-‐test thresholds total-‐loss 1 • set services rpm probe ISPA test icmp-‐test des3na3on-‐interface fe-‐0/0/2.0 • set services rpm probe ISPA test icmp-‐test next-‐hop 203.200.1.2
Configure RPM service
u Configure IP-‐monitoring service by using the condi3on of RPM ü set services ip-‐monitoring policy test match rpm-‐probe ISPA ü set services ip-‐monitoring policy test then preferred-‐route route 0.0.0.0/0 next-‐hop 203.100.1.2
u Define primary path by sta3c route ü set rou3ng-‐op3ons sta3c route 0.0.0.0/0 next-‐hop 203.200.1.2
