// = DESCRIPTION
// Simple implementations of the UDP Administration service.
//
// connects to a "remote" EC as a consumer, it also connects to the
// <local> EC as a supplier of events, this later EC is usually
// collocated.
// The QoS parameters for both connections must be provided by the
// user.
// To avoid infinite loops of events the Gateway descreases the TTL
// field of the events and will not deliver any events with TTL less
// than or equal to 0.
//
// = TODO
// The class makes an extra copy of the events, we need to
// investigate if closer collaboration with its collocated EC could
// be used to remove that copy.

// = DESCRIPTION
// The EC is able to use multiple multicast groups to transmit its
// data, the is given control over the mapping between the Event
// (type,source) pair and the (ipaddr,port) pair using a
// AddrServer.
// This class implements a very simple server that simply maps the
// <type> component to the <ipaddr> and uses a fixed <port>,
// provided at initialization time.
