About ddos-respo...@nfoservers.com
Well, Those poor guys are under perma DNS Amplifcation DDoS for what seems to be 2 weeks now. About 7 days ago they started sending us emails for what is less than 2MB worth of data (~500 packets) which is about how long it takes for filters to take effect. But after 1 week of communication they are not changing their procedures :( Anyone else receiving those emails? - Since most providers (at any level) are not putting any effort on BCP38.

Re: OSPF Costs Formula that include delay.
Eric, Issues: 1.OSPF (SPF) can only produce a SPT based on cost (metric). Anything else would require CSPF rather than SPF. 2. Delay is not distributed as part of an IGP update Typical constrains distributed are: bandwidth, color, some others In IETF we are working to also be able to distribute those kinds of metrics (draft-ietf-ospf/isis-te-metric-extensions) draft-ietf-mpls-te-express-path defines how to use these metrics for RSVP-TE (computation result is an ERO) however theoretically nothing precludes one (implementation) to use those for more comprehensive computation, i.e. delay could be taken into consideration as long as the path is loop free. So it would look like - compute all loop free paths to a destination and then choose one with the smallest cumulative delay. BTW - segment routing will give you this functionality day one :) Cheers, Jeff -Original Message- From: Erik Sundberg esundb...@nitelusa.com Date: Friday, January 24, 2014 12:26 PM To: Randy randy_94...@yahoo.com, nanog@nanog.org nanog@nanog.org Subject: RE: OSPF Costs Formula that include delay.

However I would like traffic to take Path 2 by adjusting the OSPF cost. I am looking for a formula that other people are using .p Thanks Erik -Original Message- From: Randy [mailto:randy_94...@yahoo.com] Sent: Thursday, January 23, 2014 9:03 PM To: Erik Sundberg; nanog@nanog.org Subject: Re: OSPF Costs Formula that include delay. - Original Message - From: Erik Sundberg esundb...@nitelusa.com To: nanog@nanog.org nanog@nanog.org Cc: Sent: Thursday, January 23, 2014 4:47 PM Subject: OSPF Costs Formula that include delay. What is everyone using for an OSPF cost formula that factors in a circuits delay and bandwidth (10M-100G)??? Thanks in advance umm..are you sure your question is not about EIGRP? OSPF has no concept of interface-delays. The default reference bandwidth for OSPF is 100M In your case if you set your reference bandwidth to 10 your 100G links would have a link cost of 1, 10G - 10, 1G-100, 100M-1000 and 10M-1 A vendor specific list would be a better place to ask. ./Randy CONFIDENTIALITY NOTICE: This e-mail transmission, and any documents, files or previous e-mail messages attached to it may contain confidential information that is legally privileged.

Opensource tools for inventory and troubleticketing
Hello everyone, I work for a small service provider starting to offer MPLS services between Europe and several african countries. At present time we own a small Cisco network, but we are starting to need a better inventory of services and network resources and better troubleticketing procedures. We can not afford acquiring complicated and expensive tools at present time.I would be grateful if you could recommend me opensource tools to cover these needs. Thanks in advance Kind regards Octavio

Of course this all fails miserably if you are using anything like MPLS underneath your OSPF. But then when using MPLS underneath, then MPLS Traffic Engineering can be used to do some interesting path computations and resiliency configurations. I wasn’t attempting to promote or discourage use of MPLS. I was merely endeavoring to point out that in an MPLS world, OSPF costs are not how you want to manage your traffic. Owen

Re: Google causes 40% drop in traffic?
There was a lot of discussion about this figure back in August when the relevant outage occurred. From memory, a large percentage of the traffic drop was from other sites breaking as a result of Google not being available. ie, a site completely unrelated to Google, potentially being served by a CDN, that was using Google Analytics on every page could fail to load and/or load/render slower as a result of the specific outage that Google had at the time. This resulted in a traffic drop for far more traffic than just that sourced from Google. A non-trivial percentage of the Internet is in some way or other dependent on things like Google Analytics/maps/etc, Facebook likes, Twitter recent tweets, etc, such that if any of those services are not available the site fails to load, either correctly or sometimes at all. The same is true in many causes for javascript/etc libraries being loaded from 3rd party sites like Google.

Re: OSPF Costs Formula that include delay.
On Fri, Jan 24, 2014 at 2:58 PM, Jeff Tantsura jeff.tants...@ericsson.comwrote: Eric, Issues: 1.OSPF (SPF) can only produce a SPT based on cost (metric). Anything else would require CSPF rather than SPF. A CSPF based protocol would be a suitable algorithm for adding hard constraints, instead of preference, such as path delay must be less than X, instead of just a weight for each edge of the graph. However, if you like: you can use a manually set cost for every link --- manually figure a weight based on bandwidth or delay at ideal utilization (but not both delay and bandwidth simultaneously). For example, if you equate cost to delay, then you might decide that the greatest delay any path through your AS/routing domain should ever see, from any pair of routers end-to-end is 120 milliseconds. Then you can scribble that down, and figure out what fraction of 120ms the delay for every IGP link is, under ideal conditions, to set your weight to the corresponding fraction of your chosen maximum weight. Then decide on a reference scale, for example: 100% = cost of 16384 Within that model, a link with 120 milliseconds delay, traversing that link costs 16384. Traversing a link with 10 milliseconds delay should have cost 1366, etc. Over multiple hops, the costs will then sum together, to give delay under idealized conditions. 2. Delay is not distributed as part of an IGP update Typical constrains distributed are: bandwidth, color, some others [snip] RSVP-TE (computation result is an ERO) however theoretically nothing precludes one (implementation) to use those for more comprehensive computation, i.e. delay could be taken into consideration as long as the path is loop free. So it would look like - compute all loop free paths to a destination and then choose one with the smallest cumulative delay. What I would like to see is dynamic computation of Delay and Utilization. Instead of merely choose the one with the smallest cumulative delay - choose the one with the smallest cumulative delay, BUT, offer load balancing over the N lowest delay links in proportion to the available utilization. For instance... if one of the paths has a link somewhere in it is that 90% congested, load balance unequally, and send a majority of packets over the path with the maximum 25% utilization, that has less than 10% in additional delay. BTW - segment routing will give you this functionality day one :) Cheers, Jeff -- -JH

Charter routing issues
Hello,
Can someone from Charter Communications enlighten us to if you are
having any issues or reach out to me directly.
We are seeing some interesting traceroutes from St. Louis, Mo to St.
Louis Charter customers via Level3, Qwest, or Cogent. Packets are being

Re: OSPF Costs Formula that include delay.
The auto-cost capability in some vendors devices seems to have left many people ignoring the link metrics within their IGP. From what I recall in the standards - bandwidth is one possible link metric but certainly not the only one. Network designers are free (and I would encourage to) pick whatever metric is relevant to them. On 24/01/2014 22:26, Erik Sundberg wrote: I am looking for a formula that other people are using .p I've started to use a combination of 3 metrics to determine my costing: * The traditional auto-cost calculation based on a 100Gbps reference which gives far more useful values than the old 100Mbps reference. * An average or nominal link latency multiplied by a factor of 200. Sometimes adjusted if I want two geographically diverse paths between the same endpoints to have equivalent costs. * Path length in km multiplied by 2. This accounts for situations when the nominal latency is too small to accurately determine and assumes 1 ms per 100 km. I then pick the largest of the above 3 metrics as my OSPF cost. -- Graham Beneke
