Dear NANOGers, I'd like to get a sense of how much ISPs care about different types of traffic engineering (at the routing level): Intra-domain: - multiple-paths between selected nodes - different (previleged) routing for specific traffic classes - traffic trunking and mapping to routing (eg: through MPLS) - OSPF/IS-IS parameter tweaking(i.e. link weights) for TE purposes - Dont care at all: use plain OSPF/IS-IS Inter-domain: - Hot potato/cold potato routing - Inbound load balancing (between peering links) - Inbound load balancing (between transit links or a mix of peering/transit) - Outbound load balancing (between peering links) - Outbound load balancing (between transit links or a mix of peering/transit) - Dont care about TE Are there other important categories of TE missed above? best -Shiv
