Doing traffic engineering right is hard. The telcos have it down pat for their voice networks, and telco-based ISPs often have applied this design expertise to their ISP network. Having a person do traffic engineering can save the ISP big bucks.
I agree that traffic engieering is important and doing it well is hard. However, I can point to many cases that demonstrate that the telco folks don't have traffic engineering down pat for their voice networks. The great majority of the cases show up in two areas: InterCO trunking and Inter-provider (telco-to-telco trunking). Of course, it just may be the telcos I deal with here in Texas. I can't speak of direct experiences with everyone in the country. -- Stan | Academ Consulting Services |internet: sob@academ.com Olan | For more info on academ, see this |uucp: {mcsun|amdahl}!academ!sob Barber | URL- http://www.academ.com/academ |Opinions expressed are only mine.
