Good News From The High-Speed Networking Front
Degrees writes "Over at Small Times there is an article about two Danish companies that want to make deploying fiber optic lines easier with MEMS-based packaging technology. (MEMS is Micro-Electro-Mechanical Systems - described here). Also mentioned is that the big three U.S. telcos are working on fiber to the home plans." And punkmac points to this eWeek article which begins "An Intel Corp. backed startup, SolarFlare Communications Inc. said Monday that it has developed a working prototype of a chip that will permit 10G-bps communications over standard CAT5e copper wiring. SolarFlare's chip will be used as evidence that 10G-bit over copper can be done, in anticipation of a draft IEEE standard to be developed later this year."
Obviously, this ain't coming to the home for a few more years (heck, Gigabit switches are only just now getting home-use priced), but it'll sure be nice to not have to re-pull all that Cat5e cabling we ran all over our house, especially since we'll probably be in our fifties by then.
At that type of transfer speed, the network should effectively vanish completely, even if we're streaming HD video to or from the downstairs entertainment center (I'm assuming that the internal bus bandwidths in the computers will have improved proportionally as well by then).
Yes, but for a telecom, re-wiring is a pretty heavy investment. Depending on what state they are operating in there are different requirements for using unionized labor, there's literally tons of mechanical equipment involved, etc.
I'm not sure where the point of diminishing returns is, but it's still quite important that someone concentrate on taking the utmost advantage of copper since a lot of people are going to be stuck with it for a while.
My sigs always suck.
Copper breaks down to easy, picks up to much interference, and is no good maintaining the speed over longer distances. They should concentrate on new technology instead of constantly trying to upgrade the old
It's funny but, that's what people said when networking vendors:
Increased modem speeds each time from 300bps to 56Kbps.
Introduced xDSL and then increased its speed.
Moved Token-Ring from 4Mbps to 16Mbps and then 100Mbps.
Move ethernet from 10Mbps to 100 Mbps to 1Gbps.
This article is about Cat5 cable. The last mile does not use Cat5 cable, so this article has nothing to do with getting a faster connection into your house. Let's mod all the "gee, I can download pr0n faster" comments as offtopic and get on with the real discussion about whether our processors are fast enough to drive 10Gbps.
Perhaps in the upcoming standarization they will finally switch to so called "jumbo frames", aka raise the maximum amount of data that can be sent in one chunk. As the singaling rate has gone up from 10Mb-1Gb, there has been a 100x increase in signaling rate and therefore a 100x decrease in the amount of time it takes one packet to cross the network. Since we are still using the same paltry sizes, cpu usage goes way up and throughput is somewhat capped. Switching to a larger frame size would allow higher throughput and lower CPU utilization. Many networking vendors have started adding support for larger frame sizes into their products for these reasons, but being added to the official standard would greatly increase the adoption of such jumbo frames.. htm
