发帖数: 38 | 1 Really! Actually I just came back from Beijing
for my 4-week-long and long expected vacation.
Have met a couple of former RITTers but none of
them is currently working with RITT. Did not get
around to visit RITT myself. I guess most people
I known have left or retired. I used to work in
the Network Switching Department (hopefully, that
is the right interpretation).
Went back to BUPT, though. She turns to be better
than I would expect. They had torn down the dorm

发帖数: 38 | 7 Hi, bluetooth
What a coincident. 把根留住 happens to be one of my favorite
songs. I don't know if your nick name is refering to that
song. Thanks for the response. I am planing go back home
pretty soon. Is RITT still at its old address? Hopefully, I
can see some old faces there.
By the way, I am pretty interested in Bluetooth technology.
But don't know too much about it. You know any good
tuitorial on the web about it? Please let me know if you
have some web addresses.
Thanks |

do you used to work in? The old office building
at Yue Tan Nan Jie is undergoing furnishing at
this moment. Most of the employees are working
at You Ke Yuan now. I am sure when you go back
you will see the old acquaintance as you wish. |

40 Years Ago, Norma Rae Understood How Corporations Weaponized Race
The most enduring image of the film Norma Rae, which was released 40 years
ago, is surely Sally Field’s titular character silently standing on a table
, holding up a cardboard sign with the word union scrawled on it. One by one
, her fellow factory workers shut off their deafening textile machines in
solidarity. The climactic scene sugges... 阅读全帖 |

Wenjun Wu's method is an algorithm for solving multivariate polynomial
equations introduced in the late 1970s by the Chinese mathematician Wen-Tsun
Wu. This method is based on the mathematical concept of characteristic set
introduced in the late 1940s by J.F. Ritt. It is fully independent of Gr&#
246;bner basis method, introduced by Bruno Buchberger (1965), even if Gr&#
246;bner bases may be used to compute characteristic sets [1]. |

Africa's Maghreb and Sahel regions recently exploded into world view with
allegations that the Madrid bombers were tied to those areas' "al Qaeda"
groups. And while United States concerns about terrorism in the region have
been increasingly voiced, critics of the administration of President George

发帖数: 536 | 35 roughly speaking, it's like this:
suppose I have 3 beams:red blue and yellow.
I use each beam transfer 1 channnel of signal,
for example, 10Gbit/s. Then I input all the
three beams into one fiber, then the system can
be upgraded from previous single channel system
of 10GB/S to 30GB/S.--This is WDM.
If I insert a lot of beams, each of which has different
color ( freq.), into one fiber, then It's DWDM. For example,
100 different colors, each color transmit 10Gbit/s,
then you can transmit 1TB/s ove |

it may requires optical switching if it becomes widely accepted, are there
any advance with that?
do you have any ideas on how it may affect the Gigabit routing?

发帖数: 536 | 37 In fact, all the present switch are still in done in
E domain, and most of the E switch are produced by
your company.(kick!) There is even some doubt about
the future of the O switch---since the E switch can
keep up with the pace of the development, why not
bother to....
The main focus on switch in WDM now is OXC w/o wavelength
converter--this is a key factor. Will the switch have
the wavelength convertor or not will fundamentlly
influence the topology of the physical network.

There are smarter ways then just popping up the link
capacity. You can achieve higher bandwidth by treating WDM
links as shared resource instead of just end-to-end
independent channels. Go to look at WashU Terra Bit Burst
Switch project for details.
Speaking of switching, CSCO bought our boss' startup for
$355M just to get on hold of the switching fabric chip they
developed. Check out www.growthneteworks.com for details.

so you mean shared capacity for difference links, based on some media
access control techniques? or just they are physically seperated 'coz of
different wavelength? is optical amplifier/sensor good enuf to carry
all of them without a glitch?
that will worth a hit. what's his next startup? :))
that sounds neat, what are the bus you guys are using in your projects?
CSCO's bus are TDM based and they also use some PCI bus for datapacket

Check your mailbox.
It's higher level than that. It uses dynamically assigned
channels to carry data bursts. Basically, bigger burst uses
more links. See the project paper for details.
I guess it has to be TDM regarding buses, and it is self
designed cuz there are issues particular to switching
issues. We have our own switch element, input processor,
and output processor. PCI buses are not quick enough for
high end swicthes, I think. How do you keep up with OC-192
links? A 6-port switc |
