Abstract
A method of identifying a cache line of a cache memory (180) for replacement, is disclosed. Each cache line in the cache memory has a stored sequence number and a stored transaction data stream identifying label. A request (e.g., 400) associated with a label identifying a transaction data stream is received. The label corresponds to the stored transaction data stream identifying label of the cache line. The stored sequence number of the cache line is compared with a response sequence number. The response sequence number is associated with the stored transaction data stream identifying label of the cache line. The cache line is identified for replacement based on the comparison.
