Re: The Gorgon's Knot. Was: Re: Verio Peering Question
| When Sprint was filtering there was a demonstrable need based on the 64meg | limit that | mainstream routers had for memory at the time. I do not see that there is | any such physical | limitation today and I guarentee that the router vendors (all two of them) | have learned the lesson | of not including enough address lines on the equipment to allow for easy | memory upgrades. So we should throw away all the 7200s and similar routers today because they are in the way of growing numbers of long prefixes, replacing them with new routers manufactured since the time of the above-mentioned lesson? And when shall we throw away the 12000s and similar routers (or components thereof) because they are underpowered in the face of routing-table growth, compared to well-established alternatives? Incidentally, the lesson learned was that sheer storage AMOUNT is only a (perhaps small) part of the problem, compared to the processing necessary to use that storage in support of dynamic routing (in terms of CPU and in terms of accesses to that memory).
