Techniques for performing user-configurable traffic management functions on streams of packets. The functions include multicasting, discard, scheduling, including shaping, and segmentation and reassembly. In the techniques, the functions are not performed directly on the packets of the stream, but instead on descriptors that represent stored packets. Output of descriptors from all traffic queues, including discard traffic queues, is scheduled. Scheduling is done using a hierarchy of schedulers. The form of the hierarchy and the scheduling algorithms used by the schedulers in the hierarchy are both user configurable. As disclosed, the techniques are implemented in a traffic management coprocessor integrated circuit. The traffic manager coprocessor is used with a digital communications processor integrated circuit that performs switching functions. The buffers for the packets are in the digital communications processor.

Techniques for performing user-configurable traffic management functions on streams of packets. The functions include multicasting, discard, scheduling, including shaping, and segmentation and reassembly. In the techniques, the functions are not performed directly on the packets of the stream, but instead on descriptors that represent stored packets. A packet's descriptor includes at least an identifier for the packet and a specifier for a set of traffic management functions to be performed on the descriptor. The user configures a set of traffic management functions for a traffic queue of descriptors. The specifier in the descriptor specifies a set of traffic management functions by specifying a descriptor queue. In multicasting, a descriptor is copied and placed on more than one traffic queue; with regard to discard, when the discard function associated with a traffic queue determines that a packet is to be discarded, the descriptor is placed in a discard traffic queue. Packets represented by descriptors in a discard traffic queue are discarded from the buffer. Output of descriptors from all traffic queues, including discard traffic queues, is scheduled. Scheduling is done using a hierarchy of schedulers. The form of the hierarchy and the scheduling algorithms used by the schedulers in the hierarchy are both user configurable. As disclosed, the techniques are implemented in a traffic management coprocessor integrated circuit. The traffic manager coprocessor is used with a digital communications processor integrated circuit that performs switching functions. The buffers for the packets are in the digital communications processor. Also disclosed are a modified partial packet discard algorithm and a frame based deficit round robin scheduling algorithm.

A contaminating metal on a cracking catalyst used for the cracking of hydrocarbons is removed by contacting the catalyst with a chelating agent which forms chelates with the contaminating metal. The chelates containing the contaminating metal may be readily separated from the catalyst.

A SHC apparatus and process comprise a catalyst precursor reactor for providing a catalyst precursor stream in downstream communication with a source of molybdenum, a SHC feed line for providing a heavy hydrocarbon feed stream in downstream communication with a heater, and a SHC reactor in downstream communication with the SHC feed line and with the catalyst precursor reactor. A process for SHC, the process comprising preparing a catalyst precursor stream comprising molybdenum in a catalyst precursor reactor, mixing the catalyst precursor stream with a heavy hydrocarbon stream to provide a catalyst precursor concentrate stream, heating a hydrocracking hydrocarbon feed stream in a heater to provide a heated hydrocracking feed stream, mixing the catalyst precursor concentrate stream with the heated hydrocarbon stream to provide a SHC feed stream, and reacting the SHC feed stream in a SHC reactor.

Ice melting compositions, methods for manufacturing ice melting compositions, and methods for melting ice are disclosed. The ice melting compositions can include a coarse deicing particle nucleus and a fine deicing particle coating substantially surrounding the coarse deicing particle nucleus. The fine particle coating can be attached or bonded to the coarse particle nucleus with a binder. The coarse particle nucleus and the fine particle coating can have a variety of particle sizes.
