Multicast Ethernet frames not bridging between wired and wireless, Netgear CPE
by Christopher J. Pilkington 11 Feb '13

11 Feb '13

I've a Netgear 7550 B90 provided by Frontier. (Yes, it's my only choice other than VSAT. Rural US. Yes, I am already looking into getting my own CPE, but humor me.) Since Frontier doesn't support IPv6, I've linux box on the LAN building an AYIYA tunnel, and doing the usual router thing on the wired Ethernet. Everything on the wired side works splendid. Wireless clients didn't seem to want to play. Further digging indicates that RA and NS don't cross the bridge from wired to wireless. Manually assigning IPv6 address and nailing NDP entries allows ICMPv6 echo request to work. Has anyone seen this class of device drop multicast between the wireless radio and the wired ethernet switch? Or am I brain dead this morning and missing something obvious? Heck, I even tried disabling WPA2 thinking it was some wonky encryption thing. Thanks, -cjp

Level3 worldwide emergency upgrade?
by Ray Wong 11 Feb '13

Does anyone have details on tonight's apparent worldwide emergency router upgrade? All I managed to get out of the portal was 30 minutes, "Service Affecting" (no kidding?) and the NOC line gave me the recording about it and disconnected me. -R>

Fiber project/IPTV multicast
by Jay Ashworth 10 Feb '13

Do any of the people who've worked with some of the IPTV delivery services mentioned here know if their live TV services can be handled via Multicast? Off-list replies are fine; will summarize if anyone else cares. Cheers, -- jra -- Jay R.

I'd also talk with Zhone, Allied Telesys, Adtran, and Cisco if for no other reason but get the best pricing you can. I'd also focus much more on your cost per port than the density since your uptake rate will be driven by economics long before port density and how much space your gear takes becomes an issue. > > > 2) I have no idea who told you this, but this is completely and utterly > > incorrect in nationwide terms.

The largest PON offering in the US is Verizon's FIOS, but AFAIK they don't interconnect with anyone at layer 2 and their layer 3 fiber connections are either Packet Over SONET, Gig E(most common), or very occasionally still ATM. I have heard of a few instances where they'd buy existing GPON networks but I've never heard of them cross connecting like this even with operators that they do significant business with in other ways. > > But it doesn't matter either way, except in cross-connects between my MDF > and my colo cages; except for GPONs apparent compatibility with RF CATV > delivery (which I gather, but have not researched) is just block-upconvert, > I don't care either way; there's no difference in the plant buildout. > This is not correct. DOCSIS is an MPEG stream over QAM or QPSK modulation and there is nothing about it that is compatible to any flavor of PON. In fact if you look at the various CableLabs standards you'll see DPoE ( http://www.cablelabs.com/dpoe/specifications/index.html) which lists how a DOCSIS system can inter-operate and provision an PON system. If you look at the two largest PON networks (FIOS and Uverse) you'll see the two different approaches to doing video with a PON architecture. Verizon is simply modulating a MPEG stream (this is block compatible to a cable plant, in fact its the same way that a HFC network functions) on a different color on the same fiber that they send their PON signalling. ATT takes another approach where they simply run IPTV over their PON network. I've listened to presentations from Verizon's VP of Engineering (at that time) for FIOS and he said their choice was driven by the technology available when they launched and they did modulated RF over their fiber instead of IPTV because that technology wasn't as mature when they started. Verizon's approach may be what someone was thinking of when they said that PON was compatible to cable signaling but that's not how it works. > > Cheers, > -- jra > -- > Jay R.

I do not have numbers, but based on what I have read. municipal deployments have occured in cases where incumbents were not interested in providing modern internet access. What may happen is that once they see the minucipality building FTTH, they may suddently develop an interest in that city and deploy HFC and or DSL and then sue the city for reason X. The normal behaviour should be: "we'll gladly connect to the municipal system". A good layer 2 deployment can support DHCP or PPPoE and thus be compatible with incumbents infrastructure. However, a good layer2 deployment won't have "RFoG" support and will prefer IPTV over the data channel (the australian model supports multicast). So cable companies without IPTV services may be at a disadvantage. In Canada, Rogers (cableco) has announced that they plan to go all IPTV instead of conventional TV channels.
