[0082] The fourth embodiment of the present invention discloses an IP communication method from an FC-MPIC node to an FC-MPIC node based on a multi-protocol fusion system, using IP communication from an FC-MPIC node E to an FC-MPIC node F ( figure 1 ) as an example, the protocol model such as Figure 7 shown, including the following steps:

[0083] Step S41.FC-MPIC nodes E and F complete link initialization with FC switch (FC-SW) C respectively to realize link synchronization, and FC-MPIC nodes E and F perform explicit or implicit exchange login with the switch respectively After the exchange login is completed, explicit or implicit port login is performed between FC-MPIC nodes E and F; after successful login, FC communication services can be provided.

[0084] Step S42. The application layer of FC-MPIC node E selects the IPFC channel to communicate with FC-MPIC node F over IP, and the TCP / UDP module receives user data from the user interface, encapsulates the TCP or UDP fram...

Abstract

The invention relates to a multi-protocol fusion system and an IP communication and FC-AE-1553 communication method between nodes. The multi-protocol fusion system comprises an FC-MPIC node supporting FC-AE-1553 and IP, an FC switch, an FC-EG gateway and an Ethernet node. The FC-MPIC node is connected to the FC switch; the FC-MPIC node comprises an NC / IPFC node and an NT / IPFC node; the NC / IPFC node supports an FC-AE-1553 network controller and an IPFC function at the same time, and the NT / IPFC node supports an FC-AE-1553 network terminal and the IPFC function at the same time; the FC switch performs signal forwarding based on an address mapping table; the FC-EG gateway is used for accessing the Ethernet node to the FC network; and the Ethernet node is connected to the Ethernet. The multi-protocol fusion system realizes the organic unification of an IP non-real-time network and an FC-AE-1553 real-time network.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multi-protocol fusion system, IP communication between nodes and a FC-AE-1553 communication method. Background technique [0002] With the characteristics of high bandwidth, low delay and high reliability, fiber channel technology is more and more widely used in domestic and foreign aerospace fields. FC-AE released FC-AE-1553, FC-AE-ASM, FC-AE-RDMA 5 kinds of protocol standards for avionics, FC-AE-1553 and FC-AE-ASM protocols are widely used at home and abroad. FC-AE-1553 is a command-response time-triggered protocol. With its high speed, high reliability, and support for real-time deterministic transmission behavior, it can build a deterministic network and is suitable for aerospace command control, data management, and data transmission of payload equipment. And so on, and the application is more and more extensive. Due to the flexibility of routing, IP communication ...
