C# topics names for multicast

Question

Hi All

do you know if in C# is it possible to create a communication between client and server using TOPIC names via multicast?

Is there any class or free messaging system able to do that? Essentially a server open a communication and send data to a channel represented by a Topic name i.e. a String e.g. "MAIN_DATA" and all clients (multiple since it is multicast) that subscribed that topic can get data out of it.

Regards

I am assuming by Topic you mean a multicast-group. Since it is possible for different clients to register themselves to different groups, and tx/rx messages accordingly.

Multicast Group Concept Multicast is based on the concept of a group. An arbitrary group of receivers expresses an interest in receiving a particular data stream. This group does not have any physical or geographical boundaries—the hosts can be located anywhere on the Internet. Hosts that are interested in receiving data flowing to a particular group must join the group using IGMP. Hosts must be a member of the group to receive the data stream.

This article has examples on how to join/leave a multicast group.

All clients registered to a specific group would send/receive data being tx/rx to that group.
