Title: Asynchronous transfer mode based service consolidation switch

Abstract: An asynchronous transfer mode (ATM) based service consolidation switch (10)includes an input/output module (22) having a to-switch port (TSPP)processor (90) and a from-switch port processor (FSPP) (92). The TSPP (90)and the FSPP (92) communicate with a bandwidth arbiter (114), multipointtopology controllers (116), and a data crossbar (117) on a switch controlmodule (32). The TSPP (90) receives traffic over links for conversion intoan internal cell format. Internal cells are buffered until allowed totransfer to an appropriate FSPP (92). Multipoint topology controllers(116) performs translations for internal switch flow control throughinteractions between the TSPPs (90), FSPPs (92), and the bandwidth arbiter(114). The bandwidth arbiter (114) performs appropriate bandwidtharbitration to allow internal cells to flow from TSPPs (90) to FSPPs (92)over the data crossbar (117).
