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
