摘要： A method, computer readable medium, and network traffic management apparatus that accesses data in a compressed file system includes obtaining an original write request from a client computing device including at least object data. The object data is compressed into a plurality of compressed blocks. A mapping of each compressed block to a portion of the object data compressed therein is generated, wherein the portion of the object data compressed therein is represented in the mapping by a unique object identifier, a start offset, and a length. The compressed blocks and the mapping are stored in at least one data storage device. At least one data access request for at least a portion of the object data is serviced based on the mapping.

摘要： An intermediary device, which behaves as a proxy for two entities after the entities have established a connection between themselves, is disclosed, as is a method that may be performed by such a device. The intermediary device can inspect a complete message, whose parts may be spread among multiple separate packets, without engaging in handshake phases with the message's origin or destination. As a first entity negotiates connection parameters with a second entity, the intermediary device stores the connection parameters as the parameters flow through the intermediary device. After the two entities have established an original connection, the intermediary device uses the intercepted parameters to form two separate connections in the place of the original connection: one between the intermediary device and the first entity, and another between the intermediary device and the second entity. To the entities, the newly formed connections appear to be same as the original connection.

摘要： A standby content switch module maintains a connection after failure of the active CSM by maintaining a replicate connection state of the connection state of the active CSM. The active CSM transmits a replicate TCP SYN segment to the standby CSM to replicate a connection state on the standby CSM. The replicate SYN is constructed to appear to originate from the client originating the connection to the active CSM. The replicate SYN further includes encoded information enabling the standby CSM to distinguish the replicate SYN from an actual SYN. The replicate SYN frame contains information needed to create a connection state on the standby CSM that is a replica of the connection state on the active CSM.

摘要： Network connection switchover is accomplished through a method comprising receiving information defining a first connection between a first network device and a computer; establishing a replication channel between the first network device and a backup device; storing backup control information at the backup device; communicating a message flow between the first network device and the computer on the first transport connection; in response to unavailability of the first network device, communicating messages on the replication channel that cause (a) establishing a second connection between the backup device and the computer; (b) continuing communication of the message flow between the backup device and the computer based on the backup control information. TCP connections, for example, can be switched from an active device to a backup device without reset or re-transmission.

摘要： A network traffic management device (NTMD) capable of gracefully handling remote file transfer errors is disclosed. A first local area network (LAN) may include a first NTMD and a client device. A second LAN may include a file server and an optional second NTMD. The first and second LANs are connected by a wide area network. The first NTMD optimizes network file transfer protocol (e.g., CIFS, NFS) operations by locally acknowledging file write command messages from the client device and reliably handling any file transfer errors that may occur by withholding flush data command messages from the client device until determining the locally acknowledged and forwarded file write commands were received by the file server. If any errors are encountered, the first NTMD returns a failed flush message to the client device or terminates the TCP/IP connection between the client device and the file server to indicate the error.
