re: Alcatel-Lucent, Cisco Clash Over Core Routers

Even so, IOS-XR already dates back to 2004 (8 years) and Junos years before that. So you can hardly call SR OS "old". You can call it mature and time-tested though. Consider the alternative; what if ALU would have written a brand new OS just for this product? Then the critique would (rightfully) be that it's unproven and immature. So I think ALU made a good call on this one. Besides, software doesn't age the way hardware does.

re: Alcatel-Lucent, Cisco Clash Over Core Routers

The age of the software is completely irrelevant because in every case cited (JunOS, IOS-XR, SR-OS) your only refering to the original build/ kernel release.

Every single 1 of those systems has been updated beyond any recognition since and all are built on a modular software architecture that uses multi-core &amp; hyper-threading capabilities in modern silicon to deliver a inter-locking set of functions/features. Alu &amp; Cisco use of FPGA tech would be interesting to understand. They all still claim to use ASICs but that can present silicon threshold challenges.

The key OS similarities are just the naming conventions. The level of original baseline code, is debateable but skewed by coding conventions &amp; definitions. I would guess its low single digits, at best.

So we should skip the origin date discussion. Its completely irrelevant.

It is ALL about $$ and the percieved risk/ reward. Cisco are very good at "sweetheart" deals when they detect meaningful competitive pressure, there incredible "hospitality" spend/ CRM profile and the technical resources they can bring to the table, they are always very difficult to beat.

True.&nbsp; IOS-XR came out in 2004, but from what I can remember, ENA, the pre-cursor to IOS-XR, was started around 2000.&nbsp; Then came the Procket acquisition, and I don't know how much that impacted IOS-XR.

re: Alcatel-Lucent, Cisco Clash Over Core Routers

You seem to be over simplifying. Just by using multi-threading and multi-core processors does not make these operating systems equivalent. Do all of them support the same level of per-feature modularity and restartability ? Do all of them support distributed state onto line cards ? I have not studied all 3 in detail to know for sure but I doubt that they are equivalent.

re: Alcatel-Lucent, Cisco Clash Over Core Routers

@ maxwell;

My point is not whether they all support the same features or graceful restart / non-stop routing capabilities or what the line-card capabilities are.

Its also not that multi-threading and multi-core makes them equivalent.Its not helpful to see them that way.

All of the above elements (multi-core/thread, NSR, GR, etc) are merely indicators.

My point is that stating when a OS was built (originally assembled &amp; released) and then equating that with what the vendors are delivering today is simplistic and facile.

Under that logic Huawei's VRP would have zero deployments. 7 years ago VRP (in its current form) didnt exist! In reality its a reverse engineered Hybrid build of Juniper &amp; Cisco OS builds. The question of core stability &amp; capability on such a platform are un-answered, because they have not matured long enough to assess. My view is a western perspective because those are my core markets. Go to Eastern Europe or the Middle East and you may get a different answer.

The level of feature density, modularity, reliability &amp; maturity a modern global vendor OS has to deliver is enormous. That's why we use the phrase carrier grade (amongst others) to describe and define them.&nbsp; And even that metric is now redundant &amp; going to move to something akin to "Cloud Caliber" to denote a never-fail platform.

So no they are not all equivalent. We can agree on that, at least.

re: Alcatel-Lucent, Cisco Clash Over Core Routers

I call it plain &amp; simple macster.

Its interesting that you deliberately chose not to comment on VRP and its maturity and just selected a single sentence.

You work for Huawei, you claim to have traveled all over the world and have industry expertise.

So why not offer a view?&nbsp; ..... Maybe you don't have one? ..... Maybe your boss has not authorized you to post?&nbsp; Who knows..

In my view, and I am calling it directly. Huawei has a long way to go. The VRP OS is relatively stable but immature and probably has a huge numbers of techs making very fast "hot patch" adjustments, on a continual basis.&nbsp; Maybe even the customer does not always know how a issue might have been fixed.

So if that's all wrong &amp; my post is nonsense - what your version of the "truth"?

Or are you still claiming every poster who says anything against Huawei is a racist bigot with a agenda?&nbsp; (Which by the way would include the LR Editorial team. UBM Tech clearly has strategic focus because Huawei is spending BIG money with them! Just check the sponsored video clips, banner ads, etc)&nbsp;&nbsp;

And (for balance) conversely that those who support Huawei are virtuous globalists?&nbsp; - Would it be inappropriate to ROFL at the use of virtuous &amp; globalist in the same sentence?!

re: Alcatel-Lucent, Cisco Clash Over Core Routers

Wow! Touchy touchy!

You wrote something. I found it funny. I pointed out the funny bit. I laughed. Why do you need to make everything about Huawei?

Remember, when you remove the impossibles, whatever remains, however improbable, must be the truth :p ROFL!!!

re: Alcatel-Lucent, Cisco Clash Over Core Routers

I cannot believe that Cisco is calling out someone else over their "10 year old operating system".&nbsp;&nbsp; At least the have ONE operating system that works on both the edge and core routers.


Unlike the koolaid drinkers at Cisco that have never found a software release train that they did not like.&nbsp; XR-IOS, IOS, CATALYST-IOS, NX-OS,JC-OS,BS-OS.....

re: Alcatel-Lucent, Cisco Clash Over Core Routers

@ macster; Its a shame you continue to chase &amp; troll my posts. You clearly have allot of free time.

The reason Huawei came into it my post is because they are relevant to the topic, been commented on. Alcatel Lucent &amp; Cisco core routers...

If you want to always make personal comments, then that shows your mentality. And it reflects on the company you work for.

Your continued quoting of Sherlock Holmes is very topical. Perhaps you were referencing this? - http://www.rsa.com/rsalabs/res...

Although, in answering my own question. I doubt that very much...
