Hi...
I am currently doing a project on "Satellite IP Network Emulator" which
requires me to setup a simple bridge which looks like the configuration
below:-
------------------------
LAN1-----|(eth0) EMULATOR (eth1)|------LAN2
------------------------
I have managed to setup the bridge already like above. The bridge works
fine.
I am new to both Linux and bridge and thus started to digest all the
material about both just recently. Below are some of my questions that i
hope this mailing list can provide me the answers.
[1] I have scanned through both brctl.c and brctld.c but didn't find any
code
that actually do the bridging work (or actual routing or forwarding packet
codes)... thus, is brctl only a bridge configurator or is it a full
standalone bridge program that includes all the packet managing
(bridging, routing, forwarding) codes? Can they exist within the code, can
anyone enlighten me on this matter?
[2] I also found something call brcfg which according to the HOWTOs can
also configure a bridge. Are they (brctl & brcfg) in anyway related? If
not, what's the difference between the two? Why do they co-exist anyway?
[3] I am still unsure whether can I use this brctl for my project. Thus, I
would like some advices from the more experienced about this. Basically, I
need to add the elements such as extra delay, packet queues, BER etc. etc.
to emulate a Satellite link. Is brctl suitable for me to use as a
foundation to build on?
Thank you.
