Transmission processing method and optical transport network equipment for associated Fibre Channel signals

Abstract

The embodiment of the present invention discloses a transmission processing method of associated fiber channel signals and optical transport network equipment, wherein the method includes: receiving FC signals through FC interface units corresponding to different FC ports; Whether the associated FC port is included in the different FC ports; if included, the FC signal received by the associated FC port is an associated FC signal, and the control OTN encapsulation and scheduling unit adopts the same encapsulation mode and scheduling path to encapsulate and process the associated FC signal Scheduling, and monitoring whether the delay difference between the associated FC signals is less than the preset delay difference; in response to the delay difference between the associated FC signals being not less than the preset delay difference, the associated FC signal received by the associated FC port Perform delay adjustment so that the delay difference between associated FC signals is smaller than the preset delay difference. The embodiment of the present invention enables an OTN device to control the transmission delay difference between associated FC ports, so as to meet the end-to-end delay difference requirement of associated FC signals.

Description

technical field [0001] The present invention relates to communication technology, in particular to a transmission processing method and optical transport network (Optical Transport Network, OTN) equipment associated with fiber channel signals. Background technique [0002] As a high-speed network technology, Fiber Channel (FC) technology is widely used in storage area networks. In recent years, FC technology has also been gradually used for remote data disaster recovery. As a mainstream transmission technology, OTN technology can meet the needs of multi-service, large-scale, large-capacity, and highly reliable transmission, scheduling, management, and protection. It is widely used in the metropolitan area network to carry private line services for large customers. [0003] At present, there is a need to use OTN to carry FC services in the metropolitan area network. An FC link may be carried by multiple FC ports. These FC ports are called associated FC ports. The FC signals ...

AI Technical Summary

Problems solved by technology

[0005] FC links have high requirements on the delay difference between associated FC ports, and long-distance transmission is difficult to meet the 100ns-level delay difference requirements between different associated FC ports

For example, a 1Gbps FC link is jointly carried by 4 FC ports, and there is a requirement for data synchronization between FC ports. If the time delay difference between FC ports is too large, data reception errors will occur.

However, since other signal transmission basically does not require delay difference, the existing technology does not have an adjustment mechanism for signal transmission delay, and cannot adjust for the transmission delay difference between FC ports, resulting in the reception of data transmitted on the FC link. mistake
