Abstract
An asynchronous transfer mode (ATM) based service consolidation switch ( ) includes an input/output module ( ) having a to-switch port (TSPP) processor ( ) and a from-switch port processor (FSPP) ( ). The TSPP ( ) and the FSPP ( ) communicate with a bandwidth arbiter ( ), multipoint topology controllers ( ), and a data crossbar ( ) on a switch control module ( ). The TSPP ( ) receives traffic over links for conversion into an internal cell format. Internal cells are buffered until allowed to transfer to an appropriate FSPP ( ). Multipoint topology controllers ( ) performs translations for internal switch flow control through interactions between the TSPPs ( ), FSPPs ( ), and the bandwidth arbiter ( ). The bandwidth arbiter ( ) performs appropriate bandwidth arbitration to allow internal cells to flow from TSPPs ( ) to FSPPs ( ) over the data crossbar ( ).
