System for admitting cells of packets from communication network into buffer of attachment of communication adapter

摘要

A method and apparatus for admitting packets into the buffer of an attachment of a communications adapter. More specifically, a discard bit is maintained in a table of the attachment to indicate whether a cell of a packet was previously discarded because of a buffer full condition. All subsequently received cells of a packet are automatically discarded if the discard bit is in the state indicating that a cell was previously discarded because the buffer was full.
