While talking to a lot of people about mpls applications (or even watching this alias or drafts :) I see a lot of confusion about calling different kinds of label switched paths as LSPs. The problem with this is that all of them have very different characteristics - based on very different control planes used to established them - with only one common part (in the first two at least) imposed label shim(s) into ip unicast packet. I think about a year ago Lou presented clear separation: * prefix based LSPs - those established based on the routes (carried by IGPs), MP-BGP, PIM etc ... * tunnel based LSPs - those established by extensions to RSVP or by CR-LDP. Now we also cold add third type: * optical LSPs - established by MPLambda based control plane in optical domains I personally hate acronyms, but maybe to avoid any further confusion we could append one letter to the LSP itself and start using P-LSP, T-LSPs or O-LSPs to clearly indicate what we are talking about ? If somebody has better suggestions feel free to propose. I just don't know anymore what one means by term "mpls tunnel". R. |
