Embodiment 1

[0017] Example 1: see Figure 1 to Figure 2 , A rate control device suitable for Ethernet transmission, which includes a central control unit 1, a rate control unit 2, an SDRAM storage unit 3, an Ethernet interface unit 4, a keyboard input unit 5, a clock unit 6, and a power supply unit 7;

[0018] After the central control unit 1 receives the interface type and interface rate input by the user of the keyboard input unit 5, it calculates and generates a rate control table and sends it to the rate control unit 2 to realize the interface rate control; and controls the rate control unit 2 and With the cooperation of the Ethernet interface unit 4, the simulation of different interface types and rates is realized; the rate control unit 2 calculates and generates the sending / receiving data clock frequency according to the rate control table, and controls the sending / receiving data time slot to realize Rate control of data Ethernet transmission;

[0019] The rate control unit 2 includes:...

Abstract

The invention discloses a rate control device applicable to Ethernet transmission. The device comprises a central control unit (1), a rate control unit (2), an SDRAM unit (3), an Ethernet interface unit (4), a keyboard input unit (5), a clock unit (6) and a power unit (7). According to the device, CPU software and hardware FPGA computing technologies are fused deeply; each interface is mutually independent and non-interfering, and rate control is realized; rate precision is not influenced by a software timing system and a software task; an error is controlled at a high power system master clock; a rate is completely consistent with a data rate of simulated equipment; and the problem that rate accuracy is low due to the fact that data sending / receiving share the same channel is avoided. Thesystem is characterized by that rate control precision is high, a technology is autonomous and controllable, portability is high, the device is not embargoed in foreign, a simulation effect is good and an economic benefit is high.

Description

Technical field [0001] The invention belongs to the field of communication technology, and particularly relates to a rate control device suitable for Ethernet transmission. Background technique [0002] Communication equipment is easy to cause damage to new equipment due to its complex system, strong professionalism, high degree of integration, and high price. The simulation training equipment based on software and Ethernet transmission has good simulation effect, low price, and low technical difficulty in development. is widely used. Ethernet has the advantages of wide application, high communication speed, strong resource sharing ability, and good openness. It is widely used in low-cost dedicated communication places such as private network communication, simulation training, and teaching demonstration. Ethernet transmission adopts the form of IP packets, the rate is relatively fixed, and the transmission is bursty, which has a greater impact on the data efficiency of accurate...
