I have no idea what and how to implement technically what they talk about as "specialices service that does not impcat...". In a packet based network, if the outgoing interface is not full, all packets will be forwarded as soon as possible. If the outgoing interface is full, then one can either queue all packets equally (M/M/1 queuing theory) or one can have multiple queues (M/M/N). If one have a specialized service that have some special treatment, then by definition that implies longer delay on other queues (as packets get reordered). Now, there are some special cases as well where the _services_ sold can be different (i.e. some business connection with some SLA that is higher than some SLA for end users paying less). What I think is sad is that they did not stop at saying for example: - Each provider of a service is required to always deliver to their customers the service they have promised to deliver. (Regardless of what other services they deliver to other customers on the same network...) Not any silly end-to-end. No silly "specialized service" etc. Then in other paragraphs they already (if I remember correctly) have wording about equal treatment, dominant provider of services etc. Patrik
