[first slide] Policy trends & terminology (1/2) [previous slide] [next slide]

* Confusion in the uses of the word Policy
o QoS policy
o IETF policy WG
o IPsec policy
o Security policy

* QoS policy
o Device-based
- simple rules (ACLs) on datagrams within each network node
- or DiffServ to avoid complexity of per-flow state
- each device (PEP) queries a policy server (PDP)
o For applying SLAs (Service Level Agreements)
o Inter-business entities relationships
o To apply over WAN networks only
- Bandwith is always less expensive than QoS on LANs
o Policy work driven by Voice over IP
o Conflict resolution is a hot topic
o Today QoS policy requires configuration of QoS on a device by device basis
