Organization: ITU-T
Publication Date: 1 May 2014
Status: active
Page Count: 74
scope:

This Recommendation provides an overview of generic aspects of linear protection switching. It covers protection schemes applicable to circuit-switched and packet-switched layer networks; e.g., optical transport networks (OTNs), synchronous digital hierarchy (SDH), asynchronous transfer mode (ATM) and Ethernet transport based protection schemes. Overviews of ring protection and dual node subnetwork (e.g., ring) interconnection schemes will be provided in other Recommendations.
