Hi,
First of all thanks for the Information.
There is a software called OSI-STACK from Unisys corp.This product
implements the OSI stack (service & protocol specifications of
N/W,Transport,Session,Presentation,ACSE & ROSE( appln. services ) layers)
on UNIX OS.This is menu driven ,allows to configure the transport,N/W
parameters.. We can selectively load the modules & drivers of different
layers depending on our applications.
Is there any such thing available under Linux ?
I found some modules implementing ROSE,LAPB,X25 under Linux. Can
u please help me in listing all the modules which make up the OSI stack
under Linux .
also
