Problems solved by technology

[0010] In view of the fact that the existing CORBA technical standard cannot effectively support multiple transmission protocols at the bottom layer when it is applied in the software radio system, it is possible to choose the wrong transmission protocol when the application modules communicate with each other. For the technical problem of performance degradation, the present invention proposes a general transmission protocol framework for CORBA middleware. Based on this general transmission framework, no matter which transmission protocol is used in the bottom layer, for the application module, it only needs to use the existing Ethernet-based IIOP (InternetInter-ORBProtocol, Internet ORB Interoperability Protocol) protocol, thus avoiding the possibility of choosing the wrong transmission protocol when application modules communicate with each other

Embodiment Construction

[0033] The general transmission protocol framework of the present invention is introduced in detail below in conjunction with accompanying drawing:

[0034] figure 2 Show a kind of general transport protocol framework for CORBA middleware, comprise IIOP module, Socket socket module, network protocol stack module and some virtual network cards, wherein:

[0035] The IIOP module, on the one hand, is responsible for receiving the request from the client ORB core, encapsulating the request into a standard IIOP message and sending it to the Socket socket module; on the other hand, decapsulating the received IIOP message Send to the server ORB core for analysis; the IIOP protocol is the mapping of the TCP / IP protocol in the CORBA communication network. It is a specific implementation of the GIOP (General Inter-ORB Protocol) protocol. GIOP includes encoding methods, message formats and There are three parts to the underlying network transmission requirements. GIOP adopts CDR (Commo...

Abstract

The invention relates to the field of wireless communication, and specifically discloses a general transmission protocol frame aimed at CORBA (Common Object Request Broker Architecture) middleware, a communication system and a method. The general transmission protocol frame comprises an IIOP (Internet Inter-ORB Protocol) module, a Socket module, a network protocol stack module and a plurality of virtual network interface cards, an IP message from the Socket module is converted into corresponding protocol message through the corresponding virtual network interface card, then, the converted message is sent to a server through a corresponding bottom drive program; the message received by the server is sent to the corresponding virtual network interface card through the corresponding bottom drive program, and the virtual network interface card packages the message into the IP message and further sends the packaged message to the Socket module. When a new bottom transmission mechanism needs to be supported, modification on own codes of the CORBA is not needed, support to the new transmission mechanism is added in the network protocol stack of an operating system, and thus, possibility of lowering performance of the CORBA is avoided.

Description

technical field [0001] The invention relates to the field of wireless communication, and is suitable for a software radio system that uses CORBA (Common Object Request Broker Architecture, Common Object Request Broker Architecture) technical standards to shield various data transmission mechanisms adopted by a hardware platform, specifically a CORBA middleware The general transmission protocol framework can adopt a set of unified operation procedures, shield the various underlying data transmission mechanisms adopted by the hardware platform of the software radio system, and provide consistent communication between different applications running on the CORBA middleware The communication protocol meets the standard communication requirements between different applications in the software defined radio system. Background technique [0002] Due to the endless and continuous emergence of multiple communication systems, as well as the different communication needs put forward by ...
