    摘要: Techniques for routing a payload of a first network protocol, which includes header information for a second network protocol, include communicating a packet. In a circuit block, a first type for the first network protocol and a second type for the second network protocol are determined. The circuit block stores a classification that indicates a unique combination of the first type and the second type. A general purpose processor routes the packet based on the classification. Processor clock cycles are saved that would be consumed in determining the types. Furthermore, based on the classification, the processor can store an offset value for aligning the header relative to a cache line. The circuit block can store the packet shifted by the offset value. The processor can then retrieve from memory a single cache line to receive the header, thereby saving excess loading and ejecting of cache.

    摘要: Asphalt and elastomeric polymer compositions crosslinked with mixed polythiomorpholines or at least one alkyl polysulfide can give polymer modified asphalts (PMAs) with improved properties and/or reduced H2S evolution. When at least one alkyl polysulfide is used to completely or partially replace conventional crosslinkers such as S or MBT, mercaptobenzimidazole (MBI) may be optionally used as a co-crosslinker. The use of mixed polythiomorpholines as crosslinkers provide PMAs with better low temperature profiles (BBR m-values). The use of at least one alkyl polysulfide crosslinker gives PMAs with improved PAV-aged DSR results, and reduced H2S evolution. The use of at least one alkyl polysulfide crosslinker together with MBI may give PMAs with improved PAV DSR Fail Temperatures.
