All very nice but what happens when one VoIP office needs to talk to another VoIP office over the packetized carrier. The analog voice data will be packetized in the first office to pass over there LAN converted to analog for the connection into the carrier who convert back to packetized data to cross this carrier, converting back to analog to interface with the second office who the re packetize to cross their LAN. With all the buffering required to do this what's the quality going to be like at the far end and will it sound like I'm calling from the moon?
Are you sure that that is an Urban myth, I'm sure I ve heard it from my father that an NCR tape upgrade was just a jumper setting. Then I believe that an upgrade for Phoenix disc (A couple of MByte the size of a washing machine)was just a switch setting.
Anybody else identify the expensive jumper setting upgrade.
Just because all you need is a laptop a antennae and some good skills to break into a WaveLan
Shouldn't that be all you need is a laptop an antennae and some good skills to break into an unsecured Wavelan
There is plenty that you can do on existing WLANS to lock down access, disable broadcast SSID, enable WEP,use MAC ACL's within the access point and even treat the WLAN as an insecure LAN and VPN tunnel through to the LAN. On top of this the latest kit gives you 802.1x Access control and WPA encryption and EAP authentication.
It may therefore take a little more than good skills to break into a well administered modern WLAN
"Administrators aren't sure what anybody needs that kind of bandwidth for yet, but they are curious to see how it gets used"
I am interested to find out how the administrators will find out how the links are being used. What hardware/software has the power to track this level of traffic on a switched network.
Will they be using integrated RMON2 NAM cards in the switches or possibly analysis of Netflow data from the routers.
However they do it there will be a geat deal of data to crunch
Some PSWs use public transport or Many PSWs use public transport but not PSW's use public transport.
The point here is I think that a lot of people would be happy to give up there daily commute by car for public transport if that public transport was clean, safe, reliable, inexpensive and you could get from your starting point to your destination with minimum changes.
So take one creaky old unreliable public transport system and force thousands of extra people onto it. Good idea Mr Livingstone.
Oh What happens to the not incosiderable amount of traffic that was driving through central London. I'm sure those in the area immediatly surrounding the "pay zone" will be happy for all the extra traffic.
Sure Peak Music Power has no accepted definition but I think that it is generally accepted in the LoFi world to be the power derived from Peak to Peak measurement of the voltage and then multiplied by the number of channels.
Yes and no, the retro thrusters wont help in couneracting the high speeds required for conventional flight but they will help in couteracting the force of gravity. Think perhaps of a hopper rather than than conventional plane.
It is said that the XBox is being sold at a loss but does that automatically mean that it is a good deal if it is hacked to make a general purpose computer. The CPU is soldered and non-upgradeable, the memory again is soldered and non upgradeable. The hard disk and PSU are "non standard"
Can an open platform, boxed general purpose computer with similar spec be built for the same or simlar money
Anyone who says that the XBox would make a good cluster node should price up a similar spec motherboard + CPU + memory + NIC+ case. I believe that this should come in cheaper and be far more upgradeable

The main point to remember here is that the carriers' MPLS VPN service was an alternative to having to build a private country wide 300 node network. It would be pretty expensive to do this where each site requires E1(T1) access. Even once it's built it would cost a fortune to run and manage
When encryption is required, eg. for financial data, encryption is done in hardware (NIC -> Router) this is not my area so I don't know how keys are handled
As to why the industry is pushing VPN's, It may be that to large service providers bandwidth is pretty cheap. MPLS VPN's provide them with a way that they can productize this bandwith while keeping logical separation between the customers networks. Customers can even use the same IP address ranges.

The above post so looks loke a troll, however in case the poster is serious and is in need of a whack with a clue stick...
Hubs / repeaters / fanouts work at the electrical signal level.
Bridges / Switches work at the frame level.
In limited circumstances i.e. there are only two devices talking on the segment the cheap hub may well be faster than any $20,000 switch.
Start throwing more devices, full-duplex operation etc. into the conversation and you will soon see the light.
Now when you have touched a network outside of your bedroom please feel free to respond

Interesting,
How does the cable powered device request power before it's got any?
Is it really unexpected that Cisco would play down security issues on their training course.
"No don't worry yourselves on security just BUY MORE"
Then agian dont worry that standards are still emerging and this stuff will be out of date within two years.
Don't worry that interoperability with many PABX is only partial.
Don't worry that you may loose many of the smart features of your current PABX.
Dont Worry, BUY MORE

Correct I don't live in London, but I have both lived and worked there.
Many may use the cars for convenience, but many more will use them out of necessity. Anybody with more to carry than a brief-case and a brolly.
Raise the charge to £50 and you will turn London into a wasteland. No buisiness in its right mind would want to be located there.
Aren't things bad enough in London for public service workers. Those on lower pay will find £5 a day crippling.
Raise the charge to £50 and the roads will be clear for the Bentleys and Rollers.
How about no road chargeing bet a wiser spend on public transport and an integrated transport policy.
This whole policy smells of a way of providing clearer roads for the affluent at the expense of the working man.
This is all the more suprising as the deal is being brought in by a left wing mayor (also known for throwing the comman man off low walls)
