We propose a flexible shared-per-group (SPG) architecture for wavelength selective switch (WSS)-based reconfigurable optical add/drop multiplexers (ROADMs) to support dynamic datacenter wavelength-convertible networks.The key components of this module are grouping installed tunable wavelength converter (TWCs) and tunable filter (TFs).Using the SPG
There are no uniform methods in the classification of types of humor.Sometimes, they are categorized according to the topic, which is not of much help in recognizing the main and artistic types of humor.Sometimes, humorous methods and the main types of humor are combined with each other, which is a sign of impulsiveness and lack of mastery of the s
