> So XR has no future for <100G kit? Warning largely content free pondering follows. This is not XR specific, market is no longer driven by service providers/access networks, but by content networks. And content networks want ever faster interfaces in ever denser form factor. 1GE is gone, non-LR 10GE is essentially gone. Service providers are 2nd class citizens, we have to work with what market produces for content networks. Couple years ago it was possible to build SP network with L3/MPLS with full DFZ all the way to the edge. Now those platforms are legacy, largely due to RIB constriction, and there is nothing coming from vendors to replace those. The answer for 1GE and 10GE is satellite (yuck!) or L2, so we're back to 90s with L2 edges. I wonder if this is missed opportunity, do vendors really think that everything is going ever faster rates or is just calculated, is SP market too small to justify making those 1GE and 10GE optimised full-DFZ boxes? Clearly home users aren't driving 10GE, 100GE, 400GE demand, and I don't anticipate this changing soon. Perhaps vendors still think market is same as it was 5-10 years ago, where everyone wanted faster connection on every cycle, but we're now in era where there are different Internet needs, some of those Internet needs have no need for higher capacity and never will. I suspect the market of lower rate ports is larger than vendors think it is. -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
