Network_Sim- patch DCTCP後執行檔案 找不到變數

執行tcl檔 --> ns simpleDumbbell.tcl
ns:myTrace file3: can't read 'dctcp_alpha_ ': no such variable
while executing
'subst $[subst $var]'
(procedure '_o154' line5)
(object next line 5)
invoked from within
'_o154 next dctcp_alpha_'
('eval' body line 1)
invoked from within
'eval $self next $args'
(procedure '_o154' line18)
(Agent set line 18)
invoked from within
'$tcp($i) set dctcp_alpha_'

(procedure 'myTrace' line8)
invoked from within
'myTrace file3'
_____________________________________________

就錯誤的地方看來是 dctcp_alpha_ 這個變數不存在
有人可以幫我解答我需要修改甚麼地方嗎?
