Rate shaping in Active E FTTx networks
by Jason Lixfeld 27 Jul '12

27 Jul '12

Hi all, I'm trying to gauge what operators are doing to handle per-subscriber Internet access PIR bandwidth in Active E FTTx networks. I presume operators would want to limit the each subscriber to a certain PIR, but within that limit, do things like perform preferential treatment of interactive services like steaming video or Skype, etc., ahead of non-interactive services like FTP. My impression is that a subscriber's physical access in these networks is exponentially larger than their allocated amount of Internet access. This would leave ample room on the physical access access for other services like Voice and IPTV that might run on separate VLANs than the Internet access VLAN. That said, I doubt there's really that much of a concern about allocating PIR on these other service VLANs. So in terms of PIR for Internet access, is there some magic box that sits between the various subscriber aggregation points and the core, which takes care of shaping the subscriber's Internet access PIR, while making sure that the any preferential treatment of interactive services is performed. Is that a lot to ask for one box? The ridiculously deep buffers required in order to shape to PIR vs. police to it (because policing to a PIR is just plain ugly) and the requirements to perform any sort of preferential packet treatment above and beyond that seem like quite a lot to ask of one box. Am I wrong? Who might make a box like this, if it exists? And if not, what are folks using the achieve these results? Thanks in advance for any insights..

DDoS using port 0 and 53 (DNS)
by Frank Bulk 26 Jul '12

26 Jul '12

Several times this year our customers have suffered DDoS' ranging from 30 Mbps to over 1 Gbps, sometimes sustained, sometimes in a several minute spurts. They are targeted at one IP address, and most times our netflow tool identifies that a large percentage of the traffic is "port 0". The one from today had about 89% port 0 and 11% port 53 (DNS). If it happens repeatedly or continuously we just have our upstream provider blackhole the target (victim) IP address. I've been tempted to ask our upstream provider to block all traffic to us that's targeted to tcp or udp port 0 -- is that safe to do? I found two NANOG archives that talk about this http://www.nanog.org/mailinglist/mailarchives/old_archive/2005-04/msg00091.h tml http://www.gossamer-threads.com/lists/nanog/users/18990 and the first suggests that port zero could really be fragmented packets. Unfortunately I don't have packet captures of any of the attacks, so I can't exam them for more detail, but wondering if there was some collective wisdom about blocking port 0. Regards, Frank
