Hello, I have some questions in the RFC 3270 - MPLS Support of Differentiated Services. What does establishing an E or L LSP with bandwidth(BW) reservation mean? Does it mean that the BW that has been 'reserved', for say an L-LSP should be subtracted from the corresponding PSC's BW pool before performing the admission control for another L LSP with BW reservation request for the same PSC? For example, assume a link with 10 Mbps BW reserved for a certain PSC. Now a request comes for a L LSP with required BW reservation of 5 Mbps and is admitted. Now if another L LSP request comes with the same PSC, and BW requirement of 7 Mbps, should I reject the request or accept it? (considering that I cannot adjust the queue weights dynamically)? Also, what does reserving BW for an E LSP request (with multiple PSCs) mean? Should I then subtract the LSP's required BW from the total BW of the related PSCs, if I accept this LSP request? If yes, then how should one decide from which of the corresponding PSCs' BW one should subtract the BW required for that E LSP? Please help me understand.
