ARM - TCP/IP Networking Suite (UDP-IGMP)
Currently I am working with RL-TCPnet. I'm attempt to build a
network by using UDP communication protocol(with broadcast, unicast,
and multicast). I had bought a LPC1700 Evaluation Board for testing.
And now, i have facing a problem on how to use the IGMP. As what we
known, to fully support for IP multicasting, it requires
implementation of the IGMP. The creation and maintenance of a
“host group” is belongs to a “multicast
May i know LPC17xx ARM MCU able to act as the “multicast
agent”? I have try to understand some functions which is
related to UDP and IGMP. For example,init_igmp(),
run_igmp_host(), process_igmp(), udp_send(),
udp_mcast_ttl, igmp_join(), igmp_leave() and so
on. But, i can't get a solid description on the functions usage.
Thus, till now i'm still no idea with how to use it to implement a
UDP network with broadcast, unicast, and multicast capability.
Any body have idea on how to use UDP and IGMP to implement IP
Appreciate for yours prompt reply.
Thanks a lot !
