A spa cart system includes a wheeled cart with multiple shelves for carrying spa products and fully-functional equipment for providing spa services in a client's room or designated hotel site, such as a full body massage, manicure, pedicure, and many more. Selectable transportable modules include products and equipment to support a variety of diverse spa activities, such as carrying necessary equipment, including electrically-powered equipment and a massage table and positioning same for use, supporting portability such as a cart width that fits through typical narrow hotel and resort doors, allowing adjustable movement of the equipment to use locations, providing a well-organized physical station supporting the various services (e.g., a manicure treatment station), and providing modules selectable by the technician to satisfy various spa activities pre-selected by a client.

Spa cart system and method

A context switching system for a multi-thread execution pipeline loop having a pipeline latency and a method of operation thereof. In one embodiment, the context switching system includes a context switch requesting subsystem configured to: (1) detect a device request from a thread executing within the multi-thread execution pipeline loop for access to a device having a fulfillment latency exceeding the pipeline latency, and (2) generate a context switch request for the thread. The context switching system further includes a context controller subsystem configured to receive the context switch request and prevent the thread from executing until the device request is fulfilled.

A fast pattern processor having an internal function bus and an external function bus. In one embodiment, a fast pattern processor includes: (1) an internal function bus, (2) an external function bus, (3) a context memory having a block buffer and a argument signature register wherein the block buffer includes processing blocks associated with a protocol data unit (PDU), (4) a pattern processing engine, associated with the context memory, that performs pattern matching and (5) a function interface system having (5A) a controller arbitration subsystem and (5B) a dispatch subsystem.

A virtual reassembly system for use with a fast pattern processor and a method of operating the same. In one embodiment, the virtual reassembly system includes a first pass subsystem configured to convert a packet of a protocol data unit into at least one processing block, queue the at least one processing block based upon a header of the packet and determine if the packet is a last packet of the protocol data unit. The virtual reassembly system further includes a second pass subsystem configured to virtually reassemble the protocol data unit by retrieving the at least one processing block based upon the queue.

A method and apparatus for preventing denial of service type attacks on data networks is described. The method involves scanning the contents of the data packets flowing over the data network using a traffic flow scanning engine. The data packets are reordered and reassembled and then the payload contents are scanned to determine whether they conform to predetermined requirements. Data packets which do not reorder or reassemble correctly or which do not conform to the predetermined requirements may be dropped. Dropping packets which do not reorder or reassemble correctly or which do not conform to the predetermined requirements prevent denial of service attack which exploit bugs in the TCP/IP implementation or shortcomings in the TCP/IP specification The traffic flow scanning engine is further operable to determine whether the data packets are associated with validated traffic flows. Those data packets associated with validated traffic flows are assigned to a higher priority while those not associated with a validated traffic flow are assigned to a low priority, which may occupy no more that a predetermined maximum of the available bandwidth. Assigning data packets associated with a non-validated traffic flow to a low priority prevent brute force type denial of service attacks designed to clog networks.

A function interface system for use with a fast pattern processor having an internal function bus and an external function bus and a method of operating the same. In one embodiment, the function interface system includes a controller arbitration subsystem configured to process an issued function request received from at least one of the internal function bus and the external function bus and a dispatch subsystem configured to retrieve the issued function request and dispatch the issued function request to at least one associated co-processor via the controller arbitration subsystem.

Function interface system and method of processing issued functions between co-processors

A content aware network device is described that is able to scan the contents of entire data packets including header and payload information. The network device includes a physical interface for converting analog network signal into bit streams and vise versa. The bit stream from the physical interface is sent to a traffic flow scanning processor that may be, but is not necessarily, divided into a header processor and a payload analyzer. The header processor scans the header information from each data packet, which is used to determine routing information and session identification. The payload analyzer scans the data packet's payload and matches the payload against a database of known strings. The payload analyzer is able to scan across packet boundaries and to scan for strings of variable and arbitrary length. Once the payload has been scanned the network device can operate on the data packet based on the results of the payload analyzer. The scanned data packets and the associated conclusions are then passed to a quality of service processor which modifies the data packets if necessary and performs traffic management and traffic shaping on the flow of data packets based on contents of the data packets.
