Abstract: A system for servicing streaming media requests. The system includes stream director nodes and intelligent stream engine nodes, such as permanent storage devices with network interfaces. The stream director node receives a streaming media request and enqueues the request until all resources on a path from the stream engine node having the media object being requested to the user/client system have been reserved. Once reserved, the enqueued request is then serviced by requesting the stream object from the stream engine node, which then transfers the requested stream object between the stream engine node and the user/client system over the prepared path without involving the stream director node. Upon completion, the prepared path is torn down. In one embodiment the prepared path is a Label Switched Path. A provision is made for balancing the load among the stream engine nodes by duplicating stream objects on other stream engine nodes.

Abstract: The invention extends the utility of apparatus used to extract medicinal cannabis compounds into an eluate by separating a portion of medicinal cannabis compounds contained within a portion of eluate at a first extraction target level providing enough clean solvent to continue extraction operations. A high efficiency concentrator such as a rotary evaporator or a wiped film evaporator processes eluate from one or more tanks or extraction vessels creating clean solvent when extraction targets are met or when clean solvent is exhausted. This manages eluate concentration levels and limits the quantity of concentrated medicinal cannabis compounds on site at any moment in time. The invention enables a business model for keeping medicinal cannabis compounds within a legal system, and reduces pollution because law enforcement would no longer have to burn large quantities of cannabis plant matter.

Abstract: A distributed method of establishing a path in a multi-dimensional computer network comprising a plurality of nodes for transmitting isochronous data from a source node to a destination node is disclosed. A request packet is injected into the network, the request packet specifying a request to transmit the isochronous data from one of a plurality of source nodes. The request packet is routed to at least one the plurality of source nodes, and the source node determines whether it has sufficient resources to support transmitting the isochronous data. If the source node comprises sufficient resources to support transmitting the isochronous data, the source node reserves resources within the source node to support transmitting the isochronous data, and transmits an ack packet from the source node to a first neighboring node. The first neighboring node determines whether it has sufficient resources to support transmitting the isochronous data.

Each asynchronous packet comprises destination node routing information and data, and each isochronous packet comprises a path ID corresponding to a reserved path through the network, an arrival time parameter identifying a target arrival time of the isochronous packet into the switched node, and data. An asynchronous-to-isochronous converter converts the asynchronous packets into isochronous packets comprising the data from the asynchronous packets.

Abstract: This invention is directed to a method for processing file system service requests in a computer having an attached disk drive that in response to commands from the computer can write data to or read data from disk locations to reproduce stream data and non-stream data. The method comprises the steps of responding to a first file system service request by recording whether the first file system service request is for non-stream data or stream data, associating a first set of disk locations of the disk drive with the first file system service request, and preparing a first command that requires access to the first set of disk locations, the first command including control data categorizing the command as a non-stream access command or as a stream access command in response to the step of recording. The method includes transmitting the first command to the disk drive.

Abstract: A plurality of addressable storage devices (“ASD's”) store a replicated data set. A requestor multicasts a data transfer request to the ASD's. The ASD's receive the data transfer request and cooperatively designate one of the ASD's to process the data transfer request and prevent the other ASD's from processing the data transfer request. The designated ASD satisfies the data transfer request and then communicates to the requestor an acknowledgement when the processing is completed. The ASD's maintain coherency in the replicated data set.

Abstract: An architecture that utilizes the cross-check code associated with the error correction code in a data communications system as a data integrity code to protect data stored in a temporary storage buffer within a data channel. In a preferred embodiment, a cross-check encoder and comparison circuit is added to an interface circuit which receives data from a host processing system. Incoming host data is encoded to produce redundant information according to the same Reed-Solomon code implemented in the cross-check circuitry already provided in the data path to detect miscorrections by the error correction code. Cross-check redundancy generated by the interface cross-check encoder is appended to its associated data block in the block memory buffer. The integrity of the data blocks passing through the buffer is checked by utilizing the cross-check circuitry to regenerate the redundant cross-check bytes and then performing a comparison of the regenerated cross-check bytes with the cross-check bytes from the buffer.

Abstract: A method of responding to a request for data over a bus structure, such as a SCSI bus. Upon receiving a request, a data storage device releases control of the bus and accumulates the requested data in a buffer. Before the data has been completely accumulated, the device acquires control of the bus and begins transmitting the data over the bus. The beginning of transmission occurs late enough that the transmission can occur in a single burst. If the data can be transmitted over the bus in a time period t.sub.burst, then the beginning of transmitting should begin substantially a t.sub.burst period before the time at which the buffer completes accumulating the requested data.

Abstract: A process for uniformly measuring the performance characteristic of a computer peripheral by accommodating for variations in the clock rate of the host computer system is disclosed, where after connecting the target to the host and initializing the system automatically calibrates itself to the clock rate of the host and determines the parameters of the target. The user may then define a select test, a set of test, or a continuous set of tests to be run on the target. In performing the selected test or tests, the system determines the amount of overhead time associated with the host and target, and the data transfer time, before determining the various base access times of the target. Upon the determination of a base access time, the host overhead time is then removed to yield an accurate access time measurement that is independent of variable characteristics of the host computer system.
