What is AFE channel and how is it is related to socket programming?
Eyeball AnyFirewall Engine uses the concept of channels to simplify application programming. Each channel is accessed via a set of functions similar to the socket API. Like sockets, each channel represents an endpoint for sending and receiving data. However, channels hide the underlying complexity required for the NAT/firewall traversal process, such as the STUN, TURN, and ICE functionality. To make adding the functionality of AFE to an existing application easy, calls to the socket API are replaced with similar AFE API calls. For example, to send and receive data using AFE, an application calls the Send() or Recv() on a channel, instead of using the send() and recv() functions of the socket. Furthermore, AFE provides the Select() function for channels, which models the behavior of the socket API function, select().
