re: Why OTN Is Becoming More Important

There are tons of valid technical points listed below.&nbsp; However, I see absolutely no valid economic arguments.&nbsp; If its not profitable for operators, it's not practical.&nbsp; THIS is why large scale OTN deployments connecting several disjointed domains-regions-technologies have not been successful or practical to this point.


Instead of developing OTN in order to meet the needs of every data rate for every customer in every network scenario imaginable...operators should harmonize and streamline their service offerings in order to accommodate the most cost-efficient architectural models AS WELL AS move towards enabling OTN technologies.


Only with this two-phase parallel approach can operators (especially large tier 1s) hope to compete with smaller, more agile and modern market competitors with aggressive prices points and higher margins.


While I enjoy a technology rant as much as anyone...its not just about the bites and bits, rather the dollars and cents (or euros if thats your thing;)

And are these guys doing something in the OTN / ODUflex / G.HAO domain:

Any commercial success?

You mean Intune? No, I've always thought of them as being completely separate from OTN; they've got their own way of separating and grooming traffic. Plus, they're more for metro rings than for the core, aren't they?

re: Why OTN Is Becoming More Important

Completely agree with PICturethis. The only value add OTN could have brought is multi-vendor DWDM line side interop and so, just a digital wrapper. Like TMN, this is a far fetched dream as of today.


IMO, there seems to be little justification to develop a completely new switching granularity. This burdens with supporting both SONET/SDH and OTN and doesn't add any economic value.

".operators should harmonize and streamline their service offerings in order to accommodate the most cost-efficient architectural models AS WELL AS move towards enabling OTN technologies."

This is potentially the funniest thing I have ever read on these boards.&nbsp; Seriously...operators changing what they want to do because their vendors might have to spend extra money to do it.&nbsp; What planet have you been living on for the last 10 years.

Seven, If the operators and vendors had agreement to remove all legacy, then what PictureThis said is great. Now, that doesn't happen in real world. To maintain legacy, it is insane amount of overheads and multi-level encapsulations resulting in inefficiency. The solution to this is not introducing another encapsulation introducing OTN, but trying to eliminate layers.


If MPLS-TP can do it, or we could have the desired "carrier" objectives captured in MPLS, that might be a better way out.

So, if the carriers and the vendors decided to completely screw their customers...which is what you actually wrote. &nbsp;There are 2 reasons for legacy:


1 - Customers


2 - New technologies don't do everything that the old ones did and the old ones still have customers.


Really think that Phone Companies want to have Pay Phones circuits or 4 wire leased line or dry alarm contact circuits? &nbsp;And yet new ones are sold and installed (in very small volume) every year.


So, you best get over this idea of eliminating legacy. &nbsp;Can't happen. &nbsp;Frame Relay works as well now as it did in 1990. &nbsp;If that's all somebody needs, they feel no obligation to change.
