When we had an RFP for new network equipment Cisco's proposal was twice the price of the next bid. In the end Juniper won the contract. Of all the proposals only the party offering Avaya/Nortel made a judgement error and ignored a few requirements which they could have fulfilled with a bit more expensive kit and still come out as the winner. The requirements were pretty high but not impossible. We had proposals with kit from Cisco, Avaya/Nortel, H3C, Juniper and Alcatel.
If the price for the Cisco proposal was not a real price one wonders why they submit a proposal at all. Writing the proposal costs money and if they submit a f-you quote they know the will get nothing in return.
Assuming this uses the Allwinner A10 chip, What is the status of decent hardware video decoding support?
Alas the hardware video decoding on the A10 allwinner has been problematic. The XBMC team want(ed) to make a native port to the A10 and found the library to access the cedar video decoding hardware is broken. There has been an effort to solve this but despite commitment from Alwinner there has been no progress. See also http://www.j1nx.nl/xbmc-allwinner-a10-apologies-received-accepted/
Well, the actual price would be about 15,- euro per 1GB if you can believe their reseller at http://www.europe-satellite.com/EMS/webshop/online_tooken01.htm. But Avanti is not the first, Tooway has been providing a similar service for several years now.
If you can detect indvidual raindrops, I suspect detecting a marble sized radar target flying near or over the speed of sound is no problem whatsoever. While this radar is probably too big to put in a fighter a datalink from a ground based version to the fighter will solve that problem quite nicely.
I totally agree with the Juniper EX licensing issue. Why is there a difference between OSPF and OSPFv3 ? I could understand if an advanced license was needed for both or for none of them but the split is just awkward.
Not yet in North America. However in the Asia Pacific region you're out of luck. If an ISP there runs out of addresses, and in China they do, they have to NAT and/or provide IPv6. Now I grant you that the west doesn't use many Chinese webservices. But Australia is in the same boat. So in the not so distant future you will find yourself unable to use some Australian webservices if you don support IPv6. Also the BGP tables will reach 512k entries within two years. As this is the maximum for hardware forwarding tables in many (older) routers be prepared for an IPv4 slowdown as these routers will forward IPv4 traffic over the slow path. Or unreachable sites as ISP's will start to filter all prefixes longer than/24 to prevent supervisors from overloading.
You mean you want to implement the DANE proposal ? Well, you just have to wait a bit till NSSEC is widely deployed and the proposal ratified. But the protocols are already on paper. https://datatracker.ietf.org/doc/draft-ietf-dane-protocol/
And even if major components like a light transistor are developed I don't see optical computing taking off in the foreseeable future. This "diode" is kind of weak since it stops reverse light by dissipating the energy. So any non trivial computing function made with it will consume a non trivial amount of energy in the form of input light. Compare this to electronics where a switch in the on or off state doesn't use energy apart from leakage. The major thing consuming energy there is switching states, and even that is only caused by the components being non perfect, living in an non perfect world as we do.
I manage a few Bluecoat proies and Webpulse is an add-on feature. The boxes themselves offer a wide variety of lists you can subscribe to from all big filter list providers including Websense, SmartFilter, SurfControl, ALSI Intersafe and ISS/Proventia. You can also provide your own list.
Filtering is just one of the functions of the Bluecoat proxies however. For logging and reporting you don't need any contact with external services. The proxies also support intercepting and inspecting SSL traffic. The certificates stolen from Diginotar combined with these things make a perfect "I read your GMail" system.
Licences and software updates for the proxies can be downloaded from the Bluecoat website from any PC and then transferred to the box. It is however much easier to just let the box itself get the licence. But with a bit of hassle you can use Bluecoat proxies without letting them phone home. We still have two Bluecoats laying around which are end of life. But if I start them they still work and don't contact Bluecoat in any way.
Sorry, it's 1.20AM here, I'm preparing to go to sleep.
You are a cost center.
Just like you. Every employee costs money, or do you pay to go to work ? (See P. Drucker in Managing in the next Society)
You exist only to enable productive people to produce more efficiently.
That is only one of my duties. I also take care of the security of your data. Just so it doesn't get lost and to minimize lawsuits and to prevent the competition from using it.
You aren't in charge of anything.
I'm in charge of what ever management sees fit to delegate to me. If you think that the management has delegated responsibilities wrongly please take that up with them. At this time they've delegate the responsibility of keeping the network running and data secure to me. If your wishes are a risk to my responsibilities we will have a discussion.
You work for us.
No, I work for the company. Just like you.
Continue to annoy us and you will be replaced.
As said above, if you think that the management has delegated responsibilities wrongly please take that up with them.
Just like the guy in the tool room that used to guard the pin gauges and the hammers like he owned them.
So how much have tool expenses risen ? Has productivity increased enough to justify that ?
And the facilities guy who refused to add a 30 Amp circuit or run a Nitrogen line.
Do you enjoy the blackouts ? And hows the guy with the broken neck that tripped on the nitrogen line ?
The IT support model that treats everyone like a serf doing word processing is over.
If you have an IT support model like that, you're doing it wrong.
The design engineers need nonstandard hardware to do modeling. They might even need multiple computers.
Sure, and we can accommodate that. After the design engineers manager agrees with the cost. He's the one that can asses if the increased productivity outweighs the cost. And he's also the one that will get the bill.
In fact every individual user has specific and unusual needs that they understand better than you do.
Sure, and like the example above we can accommodate most of them. However there are costs associated with that. We will tell you the cost and you can accept the bill or it won't happen.
And it's Not your call. Make it happen or go extinct. Computers aren't a new special thing anymore.
To repeat my self once more, you can ask for functionality. If it doesn't interfere with my responsibilities I'll tell you what it will cost. If you accept those costs it will happen.
Many of us users understand every aspect of your network as well or better than you do,
Sorry, a corporate network is not like your home network you toy with in the weekends. You know nothing about running a corporate network and associated risks and costs. You are just annoying because you think an extra workstation costs $500,- and 1TB storage costs $100 because you saw a PC and a disk drive in a store for that price. You don't factor in the price of the infrastructure and support contracts but somehow expect to magically be able to access all company resources with it. If it crashes it should be replaced for free and all your files you stored locally should again magically reappear because it cost you 400 hours to create them.
we just have better things to do.
Indeed, so go do your job and I will do mine.
Things that are central to the business and make money.
Kind of difficult if the network is down isn't it ? Also a shame if the company is sued to bankruptcy because you lost critical infor
Hah, finger. If you want to reach me directly see if I'm logged on and echo to the appropriate terminal. Sure you need to have access to the root account, but if you don't I'm not interested in you anyway.;-)
Agreed, multihoming will add to the routing table size. However, if you look at the RIPE policy for IPv6 PI space ( http://www.ripe.net/ripe/policies/proposals/2006-01.html ) you'll see that a business will get at least a/48. With 64K networks that will suffice for most. And the big multinationals that do require more will have no problem getting it, in a single prefix. So it stays with about one prefix per business (and in a filterable range for non transit systems too) which means less fragmentation. So I don't agree that the bigger address space will lead to more routes. Only more multihoming organisations will lead to more routes. If anything, the larger address space allows to aggregate better because there is less need to utilize every bit of the space.
On the other hand I suspect fragmentation of IPv4 will increase dramatically after the RIR's run out. Because large prefixes will be cut up in smaller ones and sold/transferred to other parties. No, that's not allowed now but I bet it will be after the RIR's run out.
BGP works the same for IPv6 and IPv4, so filtering peers according to trust is still required. However the fragmentation issue is way worse for IPv4. This is because IPv6 allocations are that much bigger.
To service 100k customers it is not uncommon for an ISP to use more than 10 IPv4 allocations which normally are not continuous. That is because the ISP can only request extra IPv4 address space from the RIR after he has assigned his current allocation to existing customers. To route those allocations the ISP has to announce more than 10 routes (one for each allocation) with BGP. This is one of the reasons the full internet routing table approaches 500k routes atm.
For IPv6 the ISP can probably service all of its customers with 1 or 2 allocations. So the routing table will be about a factor 10 smaller.
(the figures are guestimates, but I think they are about right.)
Heh, I must admit I ordered a SmartQ5 recently. Cheap enough for me to be a semi impulse buy. Small enough to fit in a pocket. And I'm interested in the state of Linux distributions on arm platforms. Sofar I've planned to try the default Ubuntu, MER (meamo clone) and Android.
A dedicated tablet is still something different than a mini laptop though. I also use a flybook which can convert to tablet mode, but I seldom use it that way. Prolly has to do with my preference for a CLI.
(I ordered it at Dealextreme. Be prepared to wait a few weeks for it though. The availability information is a very freely interpreted indication)
Although ARM processors are very popular in mobile devices like phones and embedded devices, I haven't seen them much in general purpose devices after the Acorn machines (Archimedes etc.)
If these smartbooks take off it could be a nice push for desktop Linux, as the only systems from Microsoft running on Arm are windows mobile and Win/CE, which both lack desktop applications.
I agree that wired networks will be used by the big majority of businesses for quite some time. An other big advantage of wired networks is that they "just work" with very little problems. And if there is a problem, finding the cause is easy and quick. Problems with wireless networks however are a pain.
I'm sorry, but I am dutch and our approach is an half arsed attempt at the right way. The US could surely do better. Possession of certain drugs in personal use quantities is tolerated here. However growing more than about three plants is still illegal. So where do those personal use quantities come from ? One of the biggest reasons for this stupidity is the pressure of other countries, mostly france, to revert to strict illegality for anything resembling drugs. With the exception of alcohol ofcourse. Speaking of alcohol was the situation during the prohibition preferable to the situation now ? And if not why would that be any different with other drugs ?
Agreed, the volume of traffic roughly doubles every year at AMS-IX. But still the volume percentage of IPv6 went from 0,04% to 0,2%. So the increase is significant.
But incompatibility with open VoIP standards like SIP and H.323 is an issue with corporations. And there are many more protocols that don't like NAT. Think external service brokers that register internal services.
In the business world NAT must die. It's a hopeless kludge that is only being tolerated by the scarcity of public addresses.
