IETF contacts? - Fwd: Reference to historic or obsolated RFCs
Hello guys, I've sent the e-mail below to IETF, but I couldn't find a contact e-mail to address this kind of subject in IETF site. Does anybody knows which e-mail to send this? The contact page from IETF website: http://www.ietf.org/contact-the-ietf.html -- Forwarded message -- From: Livio Zanol Puppim livio.zanol.pup...@gmail.com Date: 2012/8/6 Subject: Reference to historic or obsolated RFCs To: ietf-i...@ietf.org, ietf-act...@ietf.org Hello, I don't know which contact to send this e-mail, so I'm copying the INFO and ACTION e-mail... If these are the wrong contact, can you please point me the correct e-mail? Reading the *RFC 5375* I've found references to some RFCs that are considered Historic, or have been updated. In some cases, this can lead to a misunderstand of a a section in a RFC. For example: The* RFC 5375* in section *B.2.2* states that we should avoid using /127 IPv6 prefix, but* RFC 6164* clearly says that we can use /127 prefix for Inter-Router links. In fact, the *RFC 6547*, moves the *RFC 3627*(referenced by the * RFC 5375* in the above section) to Historic status. If my point of view is indeed correct, I think that everytime a new RFC is published that proposes an *Update* to another RFC, or *Obsoletes* another RFC or moves a RFC to *Historic *status, the team responsible for it's creation needs to read every reference to that RFC and request changes in order to avoid this kind of misunderstanding. This is very important to guys like me, that only reads the RFCs. the section from RFC 5375 http://tools.ietf.org/html/rfc5375#appendix-B.2.2 B.2.2 http://tools.ietf.org/html/rfc5375#appendix-B.2.2. /127 Addresses The usage of the /127 addresses, the equivalent of IPv4's RFC 3021 http://tools.ietf.org/html/rfc3021 [RFC3021 http://tools.ietf.org/html/rfc3021], is not valid and should be strongly discouraged as documented in RFC 3627 http://tools.ietf.org/html/rfc3627 [RFC3627 http://tools.ietf.org/html/rfc3627]. -- []'s Lívio Zanol Puppim -- []'s Lívio Zanol Puppim

Re: Network diagram app that shows realtime link utilizatin

DWDM Metro Access Design
Hello, I don't know if this is the appropriate list for this kind of subject, so if anyone knows another specific list, please tell me... I'm analysing several DWDM designs to implement at my city, but I'm still a bit confusing about the Metro acess design. I'm supposed to build a physical ring topology with 6 pairs of fiber with an hub-and-spoke logical topology. The ring will have about 40Km. At the HUB we'll install our point-of-presence with a MPLS equipment, and at the spokes we'll use only IP routers. We need an flexible design where we can add or remove spokes as needed with the minimum effort possible. We are planning to have, at a initial deployment, about 200 hundred spokes, and all these spokes are talking only with the HUB site. Everything should work like in an FTTH or FTTB design, no other type of transportation is allowed (wireless and copper). We can't use SONET/SDH. The solution must be only IPoDWDM or complemented with TDMoIP at the access equipment. The problem, is that all documents that I'm reading specifies that we should be worried with faults scenarios at the spokes, so that the optical network does not stops. For example, if the OADM equipment at the spoke is down, the lambda dropped at that site will be down too... Or at least, if we use a lot of lambdas, we need to keep and eye at the points where we have regenerators. We need bandwidth from 10Mbps to 1000Mbps at these spokes. My question is: Is it possible to make such a network in a way that we don't need to worry about faults (electrical or others) at the spokes? If so, how can I do this? I don't want the spokes sites interfering directly at the operation for the whole network. Thanks for your help. -- []'s Lívio Zanol Puppim
Re: DWDM Metro Access Design
I don't rally care about the uptime at the spokes. It's not my responsability to maintain the spokes sites, we'll just give communication to our network. I know that I'll have single point of failure in my topology, like having just one HUB, but I just don't want a spoke interfering in the opeartion of my network. Ex.: I don't want a eletrical failure at one spoke interfering in the operation of other spokes... Thanks for your reply. :) 2011/3/21 Michael K.

Hello Livio: At some point you will have a single point of failure, it's just a matter of where. If you are running a single-threaded lambda or set of them into a spoke site, that node will go down should your transport gear fail. If you want your add-drop sites to be redundant through the network layer you will have to feed each spoke site from the East and West side of your ring on separate add-drop gear. That will be expensive. If price is no object, you can do that and then use your upper layer protocols to determine path availability. Or, you can build your add drop site with a single device and built-in redundancy (controller cards, power supplies, etc.) to keep the cost down. Long story short, if you need those sites to stay up regardless of anything else, you have to build two of everything at each site. It can certainly be done and many a vendor would like to talk to you about solutions I'm sure! :-) Mike -- Michael K.

Re: Network management software with high detailed traffic report
IT depends on the manufacturer. Cisco can updates OIDs even on 1 second time basis (maybe less?). A long time ago I've made an real time monitor to troubleshooting problems at the WAN. IT was not a NMS, only visual graphs using PHP and RRDtool in one page showing IfOctests, IfDiscards, IfErrors, IfNUnicast and, in some cases, BECN and FECN for frame relay. 2010/11/22 Sergey Voropaev serge.devo...@gmail.com Steinar, I'm sure that router updates its counter more often than 5 seconds.

The main idea is to have detailed monitoring of the external links and to be able to know why (by what traffic type) and when link was highly utilized. Your requirements are somewhat unrealistic. Even if your NMS can fetch SNMP counters / Netflow info every 5-10 seconds, you have no guarantee that the router *updates* the counters / Netflow info this often. Talk to your router vendor first.
