Embodiment Construction

[0017] The specific implementation of the present invention will be further described below.

[0018] Due to resource constraints and real-time requirements, most data transmission between boards in mobile communication devices uses UDP communication. Due to the complexity of mobile communication system communication, high load and multiple bursts, the existing communication methods can no longer meet the reliability and real-time performance of communication. Therefore, the present invention proposes an extended UDP communication solution based on flow control—EUDP / FC (Extended UDP scheme based on Flow Control), which can provide real-time and definite data transmission for upper-layer services of mobile communication.

[0019] EUDP / FC introduces a flow control strategy into the connectionless standard UDP communication, and expands the communication function of UDP. First of all, in order to solve the problem of complex Ethernet communication relationship, EUDP / FC introduce...

Abstract

The method comprises: subscribing the nodes required to communicate with each node in network; establishing a virtual communication relation between two nodes desired to make communication; establishing a virtual communication link between said two nodes; each virtual communication link maintains the session between a pair of nodes; according to the different QoS requirement, providing different priority for communication service; the communication service with higher priority occupies the resource of communication service with lower priority to transmit data.

Description

technical field [0001] The invention relates to an Ethernet communication method, in particular to an Ethernet communication method for real-time transmission determination. Background technique [0002] The Ethernet technology based on the CSMA / CD (Carrier Sense Multiple Access / Collision Detection) mechanism is currently the most widely used network technology in business. With the development of Ethernet switching technology and full-duplex communication technology, the separation of collision domains and the continuous increase of bandwidth have improved the uncertainty of Ethernet communication. Ethernet-based industrial applications show strong vitality and are currently widely used in various communication devices. [0003] Most embedded systems used in communication equipment are bundled with standard TCP / IP protocol stacks, and one Ethernet node needs to communicate with multiple Ethernet nodes at the same time. If you choose to use TCP, you need to create a TCP li...
