Constraints and Policies in Routing

1
Constraints and Policies in Routing

• List of Issues
• List of Desired Policies
• Plan of how we proceed beyond today

2
List of Issues

• Guaranteed Quality
• Bandwidth (today)
• Maximum delay
• No way to signal between AS
• Control mechanism to check balances
  verification
• black box approach

3
List of Issues...

• Dynamic service allocation
• rule based?
• Is agreement transitive?
• Intra-domain issues
• Can quality be checked today in intra-domain?
• Not really

4
List of Issues...

• Is global optimization Possible?
• Is this a service in itself?
• Is path selection a service?
• Is information about link a service?

5
Policy Questions

• Only exclusionary?
• Only inclusionary?
• Restrict distribution of my prefix
• Restrict AS
• QoS (Routed set of rules)
• Is this too complex?
• Security

6
Policy Questions ...

• Load Balancing
• based on price
• based on time
• based on usage
• Traffic Conditioning
• Timing

7
Policy Questions

• Policy Conflict resolution
• Accounting Policy
• How do we account?

8
Way forward

• Consolidate this information and discuss it with
  wider audience (mailing list...)
• Present some info in the next IETF meeting
• Prepare an Internet draft
• Float some of the ideas, once developed further
  to operator lists e.g. nanog
• ....
