Data processing methods and an access node

Abstract

The invention provides a data processing method and an access node. The data processing method includes the steps of receiving downstream data; determining whether the downstream data is error data or not; if yes, replacing the downstream data by inter frame gap having the same bandwidth with the downstream data, and sending replaced data. Another data processing method includes receiving upstream data; determining whether the upstream data is auto-negotiation data or not; if yes, replacing the upstream data by inter frame gap having the same bandwidth with the upstream data, sending replace data and responding the upstream data. The invention also provides the access node.

Description

technical field [0001] The embodiment of the present invention relates to an Ethernet access technology, in particular to a data processing method and an access node. Background technique [0002] In the backbone network transmission network, the carrier-grade Ethernet service has an increasing share, and in the Ethernet service, the Gigabit Ethernet (GE, Gigabit Ethernet) service occupies the largest bandwidth and is one of the mainstream Ethernet services. [0003] With the development of technology, Ethernet has new standards, which also put forward higher requirements for GE transmission, such as: the precision clock synchronization protocol standard (IEEE1588, Institute of Electrical and Electronics Engineers 1588) protocol for network measurement and control systems, The IEEE 1588 protocol is a precise time protocol, which is used for synchronous clocks in the Ethernet environment and can achieve sub-microsecond precision. However, it is difficult for the existing GE t...

[0003] With the development of technology, Ethernet has new standards, which also put forward higher requirements for GE transmission, such as: the precision clock synchronization protocol standard (IEEE1588, Institute of Electrical and Electronics Engineers 1588) protocol for network measurement and control systems, The IEEE 1588 protocol is a precise time protocol, which is used for synchronous clocks in the Ethernet environment and can achieve sub-microsecond precision. However, the existing GE transmission method is difficult to effectively support the IEEE1588 protocol

[0004] The inventor found in the research that the data transmission mode supported by GE is difficult to effectively support new network protocols, such as the IEEE1588 protocol. When the transmission link of a GE device fails, other GE devices will fail due to receiving wrong data. Initiate the self-negotiation process, and the GE device that receives the wrong data stops sending IEEE1588 protocol data to the transmission network, and resends the IEEE1588 protocol data only after the link returns to normal, making the clock synchronization relationship between the transmission network and the GE device difficult. be effectively guaranteed
