Re: [ns] Relation among Delaylink,Simplelink,LinkDelayClass

[Andrea Josi <mr_josi@yahoo.it>]

Hi again,
i believe i've solved my doubts:
in 

SimpleLink instproc init { src dst bw delay q {lltype
"DelayLink"} }

this line

set link_ [new $lltype]

creates a new LinkDelay connector and attaches it to
the link

Anyway, this approach doesn't follow the "standard" NS
philosophy based on OTCl/C++ linkage;what is the use
of LinkDelayClass in this context then ?
(by the way,the documentation refers to a Delay/Link
class, which probably was part of an old NS version)

Thanks.
