摘要:
A method for policing traffic on a computer communications network having a multitude of nodes interconnected by various communications media. An individual policer is established at each node for monitoring and/or policing the traffic incoming to that node. Traffic policy parameters are established for traffic-classes and the policy is implemented at each individual policer. Thresholds may be established and when the thresholds are met or exceeded the individual policer will export the traffic conditions at the respective node. The other individual policers or a master policer will receive the exported information. -The individual policers police the traffic incoming to its associated node depending on the traffic condition information received from all the nodes. Several classes may be handled by each individual policer. Leaky bucket algorithms may be used in some instances.

A method and a system for controlling a packet passing through a network device are provided. The method includes timestamping the packet with an arrival time when it arrives at the network device, and determining the time the packet spends in the network device. The time spent is calculated by comparing the arrival time stamp and the exit time stamp. Subsequently, the packet is labeled, based on a function of the determined time spent in the network device. The packet can be labeled, to be dropped, suppressed or temporarily stopped. The system for controlling the packet passing through the network device comprises the means for performing the above mentioned steps.

A solid state drive (SSD) employing a redundant array of independent disks (RAID) scheme includes a flash memory chip, erasable blocks in the flash memory chip, and a flash controller. The erasable blocks are configured to store flash memory pages. The flash controller is operably coupled to the flash memory chip. The flash controller is also configured to organize certain of the flash memory pages into a RAID line group and to write RAID line group membership information to each of the flash memory pages in the RAID line group.

摘要:
A media management system including an application layer, a system layer, and a solid state drive (SSD) storage layer. The application layer includes a media data analytics application configured to assign a classification code to a data file. The system layer is in communication with the application layer. The system layer includes a file system configured to issue a write command to a SSD controller. The write command includes the classification code of the data file. The SSD storage layer includes the SSD controller and erasable blocks. The SSD controller is configured to write the data file to one of the erasable blocks based on the classification code of the data file in the write command. In an embodiment, the SSD controller is configured to write the data file to one of the erasable blocks storing other data files also having the classification code.
摘要:
A mechanism for combining plurality of point-to-point data channels to provide a high-bandwidth data channel having an aggregated bandwidth equivalent to the sum of the bandwidths of the data channels used is provided. A mechanism for scattering segments of incoming data packets, called data chunks, among available point-to-point data channel interfaces is further provided. A decision as to the data channel interface over which to send a data chunk to can be made by examining a fullness status of a FIFO coupled to each interface. An identifier of a data channel on which to expect a subsequent data chunk can be provided in a control word associated with a present chunk of data. Using such information in control words, a receive-end interface can reassemble packets by looking to the control word in a currently processing data chunk to find a subsequent data chunk.
摘要:
A high speed multi-lane serial interface and method for constructing frames for such an interface are provided. Frames are constructed for transmission on a multi-lane serial interface. For each of a plurality of transmit channels, packets are fragmented into fragments. Meta-frames are generated having a size defined by a constant meta-frame length×number of lanes, each frame having a meta-frame separator and a payload. Per-transmit channel flow control information is received. Each payload has a plurality of bursts, each burst comprising a burst control word and an associated data burst, the burst control word identifying one of said transmit channels to be transmitted on the associated data burst, each data burst comprising one of the fragments for the transmit channel identified in the associated burst control word. The channels to transmit in a given meta-frame are selected as a function of the received flow control information.
