EPON mirror image upgrading method and system based on resource dynamic adjustment

Abstract

The invention discloses an EPON mirror image upgrading method and system based on resource dynamic adjustment. The method mainly comprises the following steps: monitoring a system operation state; closing the background program and emptying the cache according to the background program; and allocating a cache space, deleting wrong data, filling retransmission data and correcting a data receiving index. According to the invention, the conditions of slow speed and even disconnection caused by mirror image upgrading are greatly improved when system resources of the EPON system are relatively tense or a network environment is relatively poor, such as a full-distribution environment, an unstable optical link, relatively large optical interference and data transmission errors caused by a large amount of data transmission.

Description

technical field [0001] The invention belongs to intelligent communication and passive local area network technologies, in particular to an EPON image upgrading method and system based on dynamic adjustment of resources. Background technique [0002] EPON technology (Ethernet-based Passive Optical Network) is a new type of optical fiber access network technology. It adopts a point-to-multipoint structure and has the capability of downlink broadcast transmission and uplink TDMA (Time Division Multiple Access). 1G / 10G bandwidth capacity, with the development of business, more and more broadcast packets between the ports of the network, the user network will appear unstable, especially during the peak period of Internet access, there will be 3-6% packet loss, serious 10% of the area may reach 10%, and in a commercial environment, the system can run the memory basically reached the line, in this environment to upgrade the image, it is very likely to lose packets, data retransmiss...

[0002] EPON technology (Ethernet-based Passive Optical Network) is a new type of optical fiber access network technology. It adopts a point-to-multipoint structure and has the capability of downlink broadcast transmission and uplink TDMA (Time Division Multiple Access). 1G / 10G bandwidth capacity, with the development of business, more and more broadcast packets between the ports of the network, the user network will appear unstable, especially during the peak period of Internet access, there will be 3-6% packet loss, serious 10% of the area may reach 10%, and in a commercial environment, the system can run the memory basically reached the line, in this environment to upgrade the image, it is very likely to lose packets, data retransmission, currently can be based on the data packet Index, simple judgment whether to After retransmission, the data will be rewritten, which will consume valuable memory and CPU resources. In severe cases, OAM will be disconnected and restarted.

[0003] Data retransmission due to poor system operating environment, and a large amount of memory and CPU resources are occupied during the upgrade process, which will cause oam to drop and network disconnection, resulting in poor user experience
