一直都很喜欢爱尔兰的曲风，这个声音记得是偶尔在电台或是路过哪家cafe的时候听到，

便回去找来专辑听，干净的声音像是夜深人静的时候闺中密友互诉心事般的直接，

没有太多的修饰。 麦田音乐有介绍的帖子

之下的这个故事是讲相爱的恋人因为宗教信仰的不同而生死相隔，

轻柔的调子，惋惜的语气，讲诉一个仿佛发生在身边的故事。

My song for you this evening
It's not to make you sad
Nor for adding to the sorrows
Of our troubled northern land
But lately I've been thinking
And it just wont leave my mind
I'll tell you of two friends one time
Who were both good friends of mine

Isaac he was Protestant
And Sean was Catholic born
But it never made a difference
For the friendship it was strong
And sometimes in the evening
When we heard the sound of drums
We said it wont divide us
We will always be as one


There were roses, roses
There were roses
And the tears of the people ran together

It was on a Sunday morning
When the awful news came round
Another killing had been done
Just outside Newry Town
We knew that Isaac danced up there
We knew he liked the band
But when we heard that he was dead
We just could not understand


now fear it filled the countryside
There was fear in every home
When late at night a car came
Prowling round the Ryan Road
A Catholic would be killed tonight
To even up the score
Oh Christ, it's young MacDonald
They have taken from the door


Isaac was my friend he cried,
He begged them with his tears.
But centuries of hatred
Have ears that do not hear.
An Eye for an eye
Was all that filled their minds.
And another eye for another eye
Until everyone is blind.

There were roses...


Now I don't know where the moral is
Or where this song should end
But I wonder just how many wars
Are fought between good friends
And those who give the orders
Are not the ones to die
It's Scott and young MacDonald
And the likes of you and I

There were roses, roses
There were roses
And the tears of the people ran together

Here are some tips and problems I've met by implementation of BIC and CUBIC on NS2 , which i'd like to share with all:

1. http://netsrv.csc.ncsu.edu/twiki/bin/view/Main/BIC

2. To implement NS2.26 on Ubuntu, see following website:

   http://lycog.wordpress.com/2008/06/04/install-ns-226-on-ubuntu/

3. Attention:

   Here must be the NS2.26, not the latest version NS2.31! (NS2.6 in the website should refer to NS2.26)

4. Compilation of NS2: under the directory : home/yourname/ns-allinone-2.26/ns-2.26

   -“make clean”

   -”make”

   (I've been used “make depend” and “make”, but the makefile seemed to be destroyed.

   I used command”./config” still under this directory and then “make clean”,”make”)

5. Do according to README file in ns_bic_cubic_v1.zip

   Compile again like step 4.

6. When you verify your ns, you may receive warnings like that

   “warning: no class variable Agent/TCP/SackTS::bic_B_
   warning: no class variable Agent/TCP/SackTS::bic_max_increment_

   ......”

   to solve problem, I've added lines in ns-default.tcl which you find in directory: home/yourname/ns-allinone-2.26/ns-2.26/tcl/lib

   “# defaults defined for TCP BIC and CUBIC

   if [TclObject is-class Agent/TCP/SackTS] {

   Agent/TCP/SackTS set bic_B_ 4

   Agent/TCP/SackTS set bic_beta_ 819

   Agent/TCP/SackTS set bic_max_increment_ 32

   Agent/TCP/SackTS set bic_min_increment_ 1

   Agent/TCP/SackTS set bic_fast_convergence_ 1

   Agent/TCP/SackTS set cubic_beta_ 819

   Agent/TCP/SackTS set cubic_fast_convergence_ 1

   Agent/TCP/SackTS set cubic_scale_ 410

   Agent/TCP/SackTS set cubic_tcp_friendliness_ 1

   Agent/TCP/SackTS set bic_delay_min_ 0.1

   Agent/TCP/SackTS set cubic_delay_min_ 0.1

   }”

---just compile ns2 again and it works.

7. To implement BIC and CUBIC in TCL script, using following commands in tcl script,

   set tcpbic [new Agent/TCP/SackTS]

   $ns attach-agent $n0 $tcpbic

   set sink [new Agent/TCPSink/Sack1/DelAck]

   $ns attach-agent $n1 $sink

   $ns connect $tcpbic $sink

By step 6, when you add

“ Agent/TCP/SackTS set bic_B_ 4

Agent/TCP/SackTS set bic_beta_ 819

Agent/TCP/SackTS set bic_max_increment_ 32

Agent/TCP/SackTS set bic_min_increment_ 1

Agent/TCP/SackTS set bic_fast_convergence_ 1

Agent/TCP/SackTS set cubic_beta_ 819

Agent/TCP/SackTS set cubic_fast_convergence_ 1

Agent/TCP/SackTS set cubic_scale_ 410

Agent/TCP/SackTS set cubic_tcp_friendliness_ 1

Agent/TCP/SackTS set bic_delay_min_ 0.1

Agent/TCP/SackTS set cubic_delay_min_ 0.1”

without using if-loop, you may receive error info like

“[code omitted because of length]

: invalid command name “Agent/TCP/SackTS”

while executing

Agent/TCP/SackTS set bic_B_ 4 “

just add the if-loop showed in step 6. You can get rid of it. It may be caused of Otcl script syntax.

我已经想不起来自己幼儿园的时候是什么样的了

努力回忆，也只有父母或者外公外婆口中提到的只字片语，

关于那时的我，一些零星的描述。

这是一段自己亲身走过而记忆却留在了别人脑海中的特殊日子

孩子就是一个个浓缩的家庭的影子，也是一个个故事的开始。。。
