Optical connection hitless bandwidth or spectrum resizing

摘要: A method and system are disclosed in which a signaling message conforming to GMPLS protocol associated with an optical connection is generated transmitted by transmit node receive change the size of bandwidth network. The may include information indicative number spectral portions correspond frequencies selected ones plurality signals, signals being available carry data from node; signals. resize while traffic continues be over Optical Transport Network without service disruption client attached resized.
