Self-adaptive 10Gbps network access system and method

Abstract

The invention provides a 10Gbps network access system which comprises an automation control device, a transceiver connected with the automation control device and a programmable crystal oscillator connected with the automation control device. A 10Gbps network access method comprises steps that working of a circuit initially depends on signal lost signals transmitted by a photolectric transducer to a field programmable gate array (fpga) and global reset signals of the circuit; in an initial state, IIC does not allocate the crystal oscillator in the circuit and begins to detect 10Gbps network types in a default mode; and media access control (MAC) first input first output (fifo) or point-of-sale (POS) fifo is utilized to perform detection of two kinds of network types respectively. By means of the 10Gbps and OC192 network self-adaptive access system and method, any manual setting of network access is not required, and automatic detection and adaptation can be performed on 10Gbps and OC192 networks when an optical fiber is plugged in or pulled out.

Description

technical field [0001] The invention belongs to the field of network communication, and in particular relates to an adaptive 10Gbps network access system and method. Background technique [0002] In a complex network environment, 10G Ethernet and OC192 network access generally coexist, so for network equipment, the same network interface supports the above two network protocols, which is the most convenient for users to upgrade equipment or replace network access scheme. They can share the same type of optical module, optical fiber and hardware circuit; but their working reference clocks are different. If the network device wants to successfully switch between these two types of network access, it must be replaced from the hardware. The frequency of the crystal oscillator is used to change the reference clock frequency of network access, so as to realize the mutual switching of the two networks. If a certain network type is successfully switched, it is possible for the net...

Therefore, if you want to decapsulate the encapsulated frames (including Ethernet frames and PPP frames), you must perform complex configurations by network maintenance personnel. Wen's situation

[0003] The invention with the patent number ZL20091002556.9 and titled "A POS Port Adaptive Implementation Method" discloses a network adaptive access method, but the invention has the following defects: 1. The matching cycle is too long, 5 ~10 seconds, and this length of time will cause a large amount of data loss; 2. In this method, it is judged that "SCRAM BLE self-adaptation" and "CRC self-adaptation" are sequential, and the reference "SCRAM BLE error" is inappropriate If the line scrambling code does not match, the POS interface processing module may not be able to find the frame header, that is, the self-adaptive module cannot detect the frame, so there is no such thing as a correct error in the CRC check. At this time, its counter cannot work; 3. This method does not support the adaptive access function with Ethernet
