Structure of ION

Directory Structure of ION

[ams] Asynchronous Message Service 

is a data system communication architecture that minimize complexity in the development and operations of data systems by isolating the modules of mission systems. It is at the application service layer.

Details Description

Some c files in ams folder containing main() function. If a file contains main() function, its program is created in main directory (ION/ion-3.5.0). Here is the structure of main function and the list of programs
#if defined (ION_LWT)
int filename (int a1, int a2, int a3, int a4, int a5,
                     int a6, int a7, int a8, int a9, int a10)
#else
int main(int argc, char *argv[])
{
   return 0;
}

1. ams/library/amsd.c
2. ams/rams/ramsgate.c
3. ams/test/amsbenchr.c
4. ams/test/amsbenchs.c
5. ams/test/amshello.c
6. ams/test/amslog.c
7. ams/test/amslogprt.c
8. ams/test/amsshell.c
9. ams/utils/amsmib.c
10. ams/utils/amsstop.c  (don't know why it does not create this problem even its c file has main()) 

[bp] Bundle Protocol

Provide route computation, forwarding, congestion avoidance, and control over quality of service. It includes CGR (Contact Graph Routing).

 Bundle protocol  = Internet protocol IP

Details Description

 

 

There are a lot of c files containing main() functions in this bp folder, and almost all files have the same format as the following.

/* * * Main thread functions * * * */
#if defined (ION_LWT)
int filename (int a1, int a2, int a3, int a4, int a5,
                     int a6, int a7, int a8, int a9, int a10)
#else
int main(int argc, char *argv[])
{
     return 0;
}

After building entire ION system, all c files containing main() function are created their program in the main directory of ION system. Therefore, we have the list of program names for bp folder:

acsadmin	acslist	bibeclo	bpadmin	bpcancel	bpchat	bpclock
bpcounter	bpdriver	bpecho	bping	bplist	bpnmtest	bprecvfile
bpsendfile	bpsink	bpsource	bpstats	bpstats2	bptrace	bptransit
brsccla	brsscla	bsspcli	bsspclo	cgrfetch	dccpcli	dccpclo
dgrcla	dtn2admin	dtn2adminep	dtn2fw	hmackeys	imcadmin	imcfw
ipnadmin	ipnadminep	ipnd	ipnfw	lgagent	lgsend	ltpcli
ltpclo	stcpcli	stcpclo	tcpcli	tcpclo	udpcli	udpclo

We can run these program by using

ION/ion-3.5.0/bpchat

[bss] Bundle Stream Service

provide service to stream video, data, continuous generated application data over a DTN (delay-tolerant network).

Details Description
