Abstract
Read messages are issued by a client for data stored in a storage system of the networked client-server architecture. A client agent mediates between the client and the storage system. A sequence identification (ID) value is conveyed by each of the read requests sent from the client agent to the storage system. The read requests, which are related to a specific data segment, that are being read sequentially by an execution thread in the client are assigned with an identical unique sequence ID value. A read request having the sequence ID value that is less recent than a most recent sequence ID value already seen by the storage system are discarded.
