You are missing a crucial point here. Every ISP has to combine a number of devices from a number of vendors who dont want to see the faces of the competition. If they rely on one vendor, they'll become slaves of it. So, they have to build a multi-vendor architecture practically. 'Interoperability' is biggest challenge among all those devices. I remember how Alcatel was showing us their end to end solutions for almost anything back to back with its own core and edge devices. when we asked them to connect to mini replica of our core and metro rings, they JUST REFUSED. They said they cant guarantee performance if their devices interface with others in the core or access rings :) And this is just one instance. Every ISP has some problem with some part of their network. Reliance has one of the fastest core. They even had a successful IPTV project way back in 2001 :) that too with the legendary Mohan Tambe ( I hope you know him). That does not mean that OSS segment may not work badly. Yes, there were problems with Nortel Clarify and even 8800 boxes. All because interoperability test reports of these vendors is nothing but a bunch of nonsense. > Could be, but they chose Linux.

He said - we intend to give competition to Solaris :) Who is paying Alexey Kuznetsov for doing IP stack in Linux Kernel? What is the use of EPFL doing RSVP in Linux when no ISP can use a Linux code for pure 'end-to-end' thing. More chances are there for having BSD/BSD derived codes working in their core and edge devices. BSD TCP/IP got parents like Bill Joy, Von Jacobson, Sally Floyd and many more. All of their research speaks of nothing but BSD based systems. TCP/IP was born in BSD and even benchmarked in BSD. The documentation of Linux IP does not have even the 'discussions' which formed the basis of their TCP/IP. What we find are direct coder's views at LKML and all those point to ultimately the things done in the BSD world. > Right, but you started with blind accusations.

I could learn more from you.
