TIPC protocol

• TIPC Overview of the agreement

  TIPC It is Ericsson's open source transparent process communication protocol , It is generally used in cluster system .
  although tipc Is based on socket Realized , But with the general socket There is also a difference . Usually we use socket, Whether it's TCP Good ,UDP Good , Used to identify a pair of socket Communication for , It's just two socket Of IP Address and port number . For example, use UDP Of socket, To send a datagram To another socket, You need to specify the address of the opposite end , This address is provided by the peer device IP And port number .Socket It is managed in the kernel , When the kernel detects socket When there is data to read , You'll be notified to have this socket Process to read data .
  Usually we use socket It is necessary to specify the address of the opposite end , We must know this socket On which device , equipment IP How much is the , What port number is used , To send data .
  TIPC That solved the problem . Use TIPC, We're creating socket When , Register your own service type in the kernel , Then at the sending end , You only need to specify the service type to route from the kernel to the corresponding socket. This is the time , For the application layer , The peer address is just a service type . obviously , The kernel maintains such a routing table , You can find the corresponding service according to the service type socket. Each device has such a routing table , Their information can be shared in the whole cluster network like an ordinary routing table , All equipment can be used for socket lookup . therefore , With TIPC, We don't need to care about socket Which one was used IP, Which port .

  Tipc It also has the following characteristics ：

  Sometimes , Multiple processes provide the same service , Just for load balancing or redundant backup , In this case, you can use an integer variable instance To identify different socket, But specify the same service type . here ,socket By service type and instance Jointly designated . When sending data, you only need to specify service type And a instance value . You can also specify service type and instance An interval of , This situation is broadcast Yours datagram
  management tipc The routing table is in the kernel name server process . He maintains all the... In the cluster tipc socket. Sending datagram To someone socket Before , You can ask him
