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
