Hi Guys I have a question about DiffServ and MPLS and was wondering if someone could help me Let's imagine that there is SLS between a customer sending IP packets and MPLS provider which says something along the lines (based on SLS from IETF DiffServ ): DSCP | PHB | Profile | Treatment ----------------------------------------- 001100 | AF11 | Profile 1 | Discard non-conforming 001101 | AF21 | Profile 2 | Remark non-conforming to DSCP 001000 other | BE(DF) | none | Apply RED Like dropping 1. Am I right saying that based on that contract the provider MUST set up LSPs supporting AF11, AF21, BE and also DSCP 001000 from say PE1 to ALL(?) other his edge routers (e.g PE2, PE3, etc.)??? 2. The FTN/Classification table would look similar to : FEC | DSCP | Label ------------------------------- PE1 | 001100 | e.g17 PE1 | 001101 | 17 PE1 | * | 17 PE2 | 001100 | e.g18 PE2 | 001101 | 18 PE2 | * | 18 etc. 3. The above table assumes that IP packets are being received from this particular customer only ? 4. If IP packets arrive from different customers than it is necessary to introduced "customer identification" using e.g source address. The table would look similar to : Src IP | FEC | DSCP | Label ------------------------------- Cust1 | PE1 | 001100 | e.g17 Cust1 | PE1 | 001101 | 17 Cust1 | PE1 | * | 17 Cust2 | PE1 | * | e.g 27 Cust1 | PE2 | 001100 | e.g18 Cust1 | PE2 | 001101 | 18 Cust1 | PE2 | * | 18 Cust2 | PE2 | * | 28 that would allow to set up 2 LSPs with different bandwidth allocation... Can someone comment on that please Best regards, Alex ------- The MPLS-OPS Mailing List Subscribe/Unsubscribe: http://www.mplsrc.com/mplsops.shtml Archive: http://www.mplsrc.com/mpls-ops_archive.shtml
