Method and apparatus to monitor and analyze network information of an inverse multiplexed asynchronous transfer mode network

A method and apparatus to monitor and analyze inverse multiplexing over asynchronous transfer mode (IMA) links of an asynchronous transfer mode (ATM) network; and determine statistics regarding cells transmitted through the IMA links. An operational status of one or more individual links of one or more monitored groups of IMA links is also determined. An apparatus to determine statistics regarding one or more IMA multiplexed links of an ATM network includes one or more IMA link pre-processors to process cells from the respective one or more IMA links according to a type of the cells; a select and collapse unit to select which of the one or more IMA links to receive the processed cells from, and collapse the processed cells of the selected IMA links into one stream; and an aligner to receive the one stream of processed cells from the select and collapse unit and determine statistics regarding the processed cells of the one stream.
