bgp for ipv6 question
Hi all Can I know how many ipv6 full bgp table routes now? how many memory can run one ipv6 full bgp table? how many peer for ipv6 in Router reflector you suggest? Do you suggest to separate the ipv4 and ipv6 in router reflector? Thank you for your info

Suggestions for managed DNS provider?
Hi all, anyone have suggestions for very stable/reliable managed DNS? Neustar/UltraDNS is an obvious option to look at, just curious about alternatives. Cost effective would be nice, but stable under attack is better. Thanks, David

Not sure about attacks, or what exactly managed DNS is, but
dns.he.net. is a very nice service, with many anycast servers in many
of their POPs. The ns1.he.net. is an IPv4 unicast in Fremont, but
ns{2,3,4,5}.he.net. are all anycast on both IPv4 and IPv6, usually to
different locations (HKG, FMT, SJC, PAO, LAX, NYC, LON, FRA, AMS are
just some of the locations I've seen), depending on where you're at.
Linode also lets you use their DNS infrastructure without any
restrictions as long as you're a Linode customer (they have 5
independent unicast IPv4/IPv6 servers, 4 in US, 1 in UK).

Quantifying the value of customer support
Hello, We are a 2nd level of escalation in a service provider, trying to put a $ value on the support we give to our NOC and other implementation teams, when they email us about problems they face. But we are merely bits and bytes engineers that cant quantify and justify the value of what we do to the management team. I guess these smart suits want to see an excel sheet with a table of how much they save or gain by the support we do. We respond to technical questions and simulate problems in a lab. Can anyone help me with an idea or any material i can reuse? Templates? Has any one been in a similar situation. Thanks Kim

Re: Quantifying the value of customer support
Hey, So usually this is done by the business unit leaders. At ATT people used to call it pushing the wastebasket. The idea is that each department runs as a separate business and in order to evaluate the business you debit and credit departments as if they were counterparties in a trade. Someone usually ends up on the outside looking in. Typically, for call centers, this evaluation is done on a cases handled versus calls placed manner with time/$ values associated with every ticket. Tier 2 support costs more per person than tier 1. If tier 2 doesn't actually speed or reduce call traffic, there's no point in having a tier 2. Now, as one might imagine, there is a great deal of subjectivity in these numbers. Many teams try to tackle this by dividing salaries by hours on the phone. This can hide a lot of the value of tier 2 as the whole point is to eliminate extra time someone would've spent in tier 1 looking for the answer. Your challenge is to quantify how much time you're saving and multiply it by your salary per hour number. That's a good place to start.

RE: Quantifying the value of customer support
I would think your $ value would be calculated by a few factors. 1. How much would it cost to train and hire NOC guys that do what you do today vs. using outsourced support for those issues or going to a higher level team. 2. How much longer would SLA affecting problems take to solve without you? 3. This one is tough, how many customer implementations would fail and how many customers would you lose due to the loss of technical expertise? A super simple calculation would be something like we provided 10,000 hours of support and a consultant with similar skills would have cost X dollars or if they would have escalated to an even higher level in your organization you have to calculate the cost of your hours vs the hours of more expensive engineers. A calculation you will probably not be able to make is if a higher engineering level than you had the time and resources to handle the same cases or if they would need more body count to do so. I can't tell what your $ value is without knowing the cost of not having you. I would think the best thing to respond with would be to take some of the cases you handled and find out what it would have taken to solve the problem if you had not been there. For example, I you provided three hours of help that no one else in your organization could have, you could calculate how much an outside consultant would have cost and how long it would have taken to retain that consultant. You will then be able to say that X project would have cost this much and taken this much longer. Bottom line is what is the cost of NOT having you.

It's not 100% clear what you mean here, resolvers or authoritative DNS, but, in either case, my suggestions are the same, OpenDNS has been reliable for me as a resolver service, and DynDNS (now just Dyn) has been great for authoritative and secondary nameservers for me. For authoritative nameservers I haven't looked for anything to deal with huge numbers of domains, just a few dozen. -- Genius might be described as a supreme capacity for getting its possessors into trouble of all kinds. -- Samuel Butler

RE: Quantifying the value of customer support
There is no such thing as a generic business case that can be applied across all companies in an industry. Every business is unique in its product definition and organization structure, but each question is also unique and therefore the analysis must be done every time. The way to begin is to ask this manager what he believes the possible outcomes are (downsize your group, eliminate your group, re-define your group, etc.) and then work with each of the key stakeholders that you have to estimate the impact of those outcomes. For example, if 1st line operations indicates that eliminating your group would result in decreased customer satisfaction and missed SLA's, ask them to quantify it as much as possible and go to take the numbers back to your business people to have them estimate the impact on revenue. The analysis should be constructed and presented in standard finance terms (like NPV) so I would suggest that you make friends with someone in finance to assist you with the preparation. You can also take a short two-day course like this http://executive.mit.edu/openenrollment/program/fundamentals_of_finance_for_the_technical_executive/16 that will teach you how to build up these analysis yourself (I have taken the one referenced and I recommend it to all managers with budget responsibility). The outcome from these discussions often has surprising but positive outcomes for everyone...maintaining the status quo is not always the best possible outcome despite the biases we usually have when we begin the analysis. :-) If you work closely with all of your stakeholders, everyone will learn and benefit from the experience.
