What is Performance Routing?

PfR provides automatic route optimizationand load distribution for ISP and WANconnections.

It monitors IP traffic flows and then define policies and rules based on prefix performance, link load distribution, link cost, and traffic type

Previously called OER – Optimized Edge Routing – it has been renamed Performance Edge Routing for the new version released in October 2007.

6

Why considering Performance Routing?The Challenges• How do I choose between my two service providers and how

can I be sure that the one I am currently using provides me the best service?

• I have no bandwidth congestion but my customers are still complaining of Response Time for some business applications –is there a better network path?

• My QoS is working fine for my Voice trafficbut certain users are still experiencing some voice quality problems – is there a better network path?

7

Applications of PfR

• Ensure key applications keep within Service Level Agreements

• Allows key applications use the best performing path• Security• Load Balancing• Traffic maximising on links• Allows the use of redundant backups

– Cost Saving– Effective use of existing resources

10

What do I get?

• Performance Metrics -Delay, Jitter, MOS, Availability, Response Time, etc are measured

• Policies - Thresholds based on performance metrics applied to traffic

• Traffic Classes - categorize traffic– Defined by IP Address, Port Numbers, protocol, DSCP– NBAR to be added soon– Classes are “learned” by PfR– Can also be explicitly specified

• Apply a Policy to a Traffic Class to enforce thresholds

Policy Options• Performance monitoring – Active, Passive or Both

– Active Monitoring provided by IPSLA– Passive Monitoring uses NetFlow– Most users will use both Active and Passive

• Policy Mode – Good or Best– Good Mode: when a threshold is exceeded, find an alternative

route that falls within the threshold– Best Mode: anytime a route with better performance is found,

switch to that route• Network Control Mode – Control or Observe

– Observe Mode: no changes are made to routes, performance data is gathered. Useful for baselining and planning.

– Control mode: policies can actively change routes when needed

• Active– PfR enables IP SLA feature– Probes sourced from BRs– Icmp probes learned or configured– Tcp, udp, jitter need ip sla responder

• Passive– PfR Netflow monitoring of traffic classes

• Both Mode• Fast Mode

– Probes all path all the time

PfR Manager – Why?

• On its own, PfR can be configured and monitored via CLI:– Events and alerts via Syslog– Current performance data available on CLI

• PfR Manager Makes PfR Easier:− Easier configuration of Traffic Classes and Policies− Full historical performance statistics− Opens up PfR to less technical users− Simplifies PfR Concepts, reduces training cost− Visibility of multiple PfR domains in a single view

19

How PfR Manager Communicates with PfR

• Secure API link to the Master Controller• Receives performance statistics• Receives status of classes and exits• Receives events• Sends configuration of Traffic Classes and Policies

Configuring PfR with PfR Manager

• Define Traffic Classes– Addresses, ports, protocols,

DSCP values• Configure policy thresholds• Choose modes of operation

– Observe or Control– Good or Best– Passive or Active

• Create security policies

Graphical Reports and Intuitive User Interface• Navigation Aid

• Aggregated view of vital statistics

• Problems on the network are immediately evident

• Traffic Class and Exit Link listing with current status

• Navigation to individualExit Link and TrafficClass reports

• At-a-glance status ofeach item and performance data

22

Performance Reporting• Performance data collected from the Master Controller• High-level views of PfR Domains, devices and classes provide

navigation and high-level performance indicators• Details performance of the network• Verifies operation of PfR

• Event History for a Traffic Class• Low-level detail of all PfR alerts / events• Shows the sequence of events when a class goes OOP, etc
