Abstract
Methods and apparatus are disclosed for handling transient anomalies in a communications or computer device or system, such an inverse multiplexing for ATM ('IMA') device. Such transient anomalies may include out of IMA frame ('OIF') anomalies. In one implementation, cells comprising a stream of packets are received over multiple links along with indications of OIF conditions for these links. During a period of an inactive OIF condition on a link, cells are received over the link and placed in a buffer at a next location. After an OIF condition is detected, cells are ignored and a write process waits until the OIF condition is no longer active. At which point, a buffer position is determined to place the next valid cell. Typically, this cell should be placed in the same buffer position as it would have been if there had never been an active OIF condition.
