Method for realizing cross-ring protection of resilient packet ring by use of spanning tree protocol

Abstract

The invention relates to a distributed collection processing system and method of internet metadata. The distributed collection processing system comprises a configuration management graphical user interface module, a metadata collecting assembly module and a metadata output module, wherein the configuration management graphical user interface module is used for collecting distributed assembly parameter configuration, collecting metadata and searching input logs; the metadata collecting assembly module is used for reading metadata collection configuration of each service application system, periodically establishing and executing a collection mission dispatching program in a distributed manner, and generating metadata extensible markup language files required by each service application system; and the metadata output module is in charge of outputting the metadata extensible markup language files to each service application system. Each service application system disclosed by the invention has the advantages that universal and open distributed assemblies and services are provided for the internet metadata, so that a uniform and standard data source is provided for further realizing in-station accurate search of an internet television and vertical search of content aggregation type applications.

Description

technical field [0001] The present invention relates to the technical fields of Resilient Packet Ring (RPR, Resilient Packet Ring) and Spanning Tree Protocol (STP, Spanning Tree Protocol). The spanning tree protocol is configured on the cross-ring nodes of the elastic packet ring to realize the reliable transmission and redundant protection of the cross-ring services of the elastic packet ring. Background technique [0002] The elastic packet ring is oriented to data services and is suitable for optical ring networks in the range of metropolitan area networks. It has been standardized by IEEE (Institute of Electrical and Electronics Engineers) 802.17 working group. The elastic grouping ring is a double-ring structure consisting of an inner ring and an outer ring in opposite directions. [0003] The key features of RPR are as follows: [0004] 1. Automatic topology discovery [0005] The RPR automatic topology discovery mechanism does not require human operation, and can ...
