Publish/Subscribe Example for Endpoint Options and the usage of ports

Example
following Figure shows an example with the different Endpoint and a Multicast Option:
下图展示了一个例子，使用不同的Endpoint和Multicast Option
- The Server offers the Service Instance on Server UDP-Endpoint SU and Server TCP-Endpoint ST
  服务器提供了一个服务实例，通过UDP-Endpoint （简称SU）和 TCP-Endpoint ST（简称ST）
- The Client opens a TCP connection
  客户端打开一个TCP连接（Socket）
- The Client sends a Subscribe Eventgroup entry with Client UDP-Endpoint CU (unicast) and a Client TCP-Endpoint CT
  客户端发送一个Subscribe Eventgroup entry，带有客户端UDP-Endpoint (unicast)(简称CU)和一个客户端TCP-Endpoint （简称CT）
- The Server answers with a Subscribe Eventgroup Ack entry with Multicast MU
  服务器通过多播option（简称MU）回复一个Subscribe Eventgroup Ack entry

Then the following operations happen:
接下来这么运行：
- The Client calls a method on the Server
  客户端调用服务器端的method
- Request is sent from CU to SU and Response from SU to CU
  Request从客户端通过UDP发给服务器端，回复消息从服务器端通过UDP发回客户端
- For TCP this would be: Request dyn to ST and RESPONSE from ST to CT
- The Server sends a Unicast UDP Event: SU to CU
  服务器端发送一个Unicast UDP Event:到客户端：SU到CU
- The Server sends a Unicast TCP Event: ST to CT
  服务器端发送一个Unicast TCP Event到客户端: ST到CT.
- The Server sends a Multicast UDP Event: SU to MU
  服务器端发送一个Multicast UDP Event到客户端：SU到MU

Keep in mind that Multicast Endpoints use a Multicast IP Address on the receiver side,i.e. the client, and TCP cannot be used for Multicast
