[e2e] Network optimization for bandwidth provisioning

[=?gb2312?q?Jing=20Shen?=]

I'm sorry I made a mistake when copying web links , the paper is 
named: "Provisioning IP Backbone Networks to Support Latency Sensitive Traffic"
(http://ipmon.sprintlabs.com/pubs_trs/pubs/cdiot/infocom03_provisionbb.pdf)
best regards

Hi,

I just read  a paper published on InfoComm'03 named  "Achieving Near-Optimal Traffic Engineering Solutions for Current OSPF/IS-IS Networks", it is stated that

only 15% BW overprovisioning is needed to guarantee as low as 3ms e2e delay requirement. 

My question is:

1) a network optimization result  with both network topology, routing path preassumed  reliable?  How could we consider routing path changes when link BW is overprovisioned?

2) what's the state of link BW in current backbone network ? is there more than 15% BW idled? 

Thanks in advance.
