I have mainly worked at small and medium sized operators and we did not use IRR at all apart from registering our own and customer blocks with the one upstream provider we had (Level3) which required it. We maintained our own databases of customer prefixes tied to other customer information strict

RE: why haven't ethernet connectors changed?

There have been some smaller connectors but nothing with widespread adoption. Tyco has something called RJ point 5 which uses standard UTP cable but looks like a squashed RJ 45 and has double the density. Wouldn't save much space on a Pi thigh its meant more for bulk applications. From: Michael

Re: Inter-domain OTN, does it happen in the real world?

Most telcos can provide an OTU2 client interface but there is no peering, they are just mapping directly to a wavelength or to OTU3/4. So it's transparent service. Phil On Oct 23, 2012, at 7:07 PM, Will Orton w...@loopfree.net wrote: Reading about OTN networks, I see that IrDI is specified

Re: JUNOS forwards IPv6 link-local packets

Just since I had everything hooked up I did a quick test on IOS-XR 4.2.0 on an ASR9000 and found it also forwards v6 traffic with a link-local source address and a global destination address. The destination was a Juniper box which I tried to DoS using ICMPv6 echo requests. The 200:11ff:fe00:0

Re: EPC backhaul networks

Easier to troubleshoot is the main reason but also, you would not put the MME/S-GW in every segment with the eNodeB anyways, so in the end you'd really want a L3 routed solution between them. One of the things I've seen is the L3 interface for the eNodeB terminates locally on an attached smaller

Re: EPC backhaul networks

I work for a MSO and while we do provide L2 services today for wireless backhaul, the services are based on requirements from the wireless providers and I haven't seen an RFP yet in which someone wanted a L3 service. If someone really wanted a L3VPN as a backhaul solution we could oblige them but

Re: Some truth about Comcast - WikiLeaks style

The franchise fees in many markets are based on gross revenue. 5% is a fairly standard percentage charged by municipalities to cable companies for right of way access, etc. Not sure if I would call this a profit sharing plan, but it's not too much of a stretch. Today with local agreements

Re: Level 3 Communications Issues Statement Concerning Comcast's Actions

Is L3 hosting content for Netflix? Netflix has become a large source of traffic going to end users. L3 likely could have held out on this one if the content they were hosting is valuable enough to Comcast's customers, but maybe what Comcast was asking for wasn't much in the grand scheme of

Re: Alcatel-Lucent

I've done some recent testing and while the BGP download time isn't blazing fast, it can load 400k routes and propagate them to 20 other peers in a few minutes. Certainly not 2 hours. :) I've also done quite a bit of interop testing with the other main vendors as well and have yet to run

Re: BFD over p2p transport links

We use it on all of our links which are generally over our own DWDM/dark fiber network. All links are 10G LAN PHY. Our DWDM systems propagate link failures but one of the main reasons we implemented it was our router vendors did not drop link during reboots during software upgrades. GR

Re: Help needed - Cisco Netflow

It depends on how many active flows you have at any one time. Also, I don't think the SIP-601 supports full netflow V5 in hardware, only V8, which is aggregated netflow, which may not be what you want. It does do V5/V9 sampled netflow in hardware. The sampled netflow on that platform is
