Abstract

The invention discloses a device for error checking and correcting in a generic frame procedure and a control method thereof. The device provides a quick, high-efficiency and simple CRC-16 error checking and correcting device and a control method thereof, against the problems of error control for information of kernel header and payload header in GFP frame, according to the CRC-16 error control technique being the kernel of error control for information of the kernel header and the payload header in the GFP frame, and against the design based on CRC-16 single-bit error checking and correcting. The device adopts the design of four ROMs, a simple calculator and a three-stage pipeline register, so that the process for error checking and correcting can be very simple; moreover, the device hassimple requirement on hardware, and is applicable to a high-speed EoS system.

Description

technical field [0001] The invention relates to a device for detecting and correcting errors in a general framing protocol and a control method thereof. Background technique [0002] With the rapid development of the network, the datagram service represented by the IP service has also achieved rapid development, and has occupied the main market in the current network service. In order to ensure the reliability of the datagram in network transmission, we have adopted some encoding techniques. Among them, a Cyclic Redundancy Check (CRC) is the most commonly used encoding technology. Before the IP service enters the SDH (Synchronous Digital Hierarchy, SDH) backbone network for transmission, it needs to be encapsulated to solve the contradiction between the constant rate of the backbone network and the burstiness of the IP service. Generic Framing Procedure (GFP) is one of the encapsulation technologies. A GFP frame is composed of a core header and a payload. The core header...
