What is Crossbow?
Crossbow is a set of technologies that provide network virtualization and greatly improves the resource control, performance, and network utilization needed to achieve true OS virtualization, utility computing, and server consolidation. Crossbow consists of multiple components: • IP Instances • Virtual NICs (VNICs) • Flow Management Crossbow is designed to add network virtualization to Solaris without introducing any performance penalty. Some of the underlying work is delivering better network performance. Receive rings and hardware classification, and multiple MAC address support contribute to better performance and enhance the virtualization provided. Flow management could introduce some overhead. If the NIC or VNIC is not doing any fanout and B/W control, Crossbow can map a flow directly to a receive (RX) ring and use hardware to classify it. In that case, there is no performance impact. In cases where the NIC or VNIC is already doing bandwidth control or traffic fanout across multi
A crossbow is a modified bow and arrow system. Invented by the Chinese as early as 6 B.C. for military use, it did not become popular in Europe for several thousand years. The crossbow has a bow attached to a stock, allowing it to remain loaded when not in use. A lever attached to the stock aides in the loading of the crossbow. When the lever is released, the arrow, or bolt, will fire. Crossbows are deadly accurate and have a firing range longer than a traditional longbow. They are easier to operate and are the perfect weapon for those who do not have the strength to effectively pull the classic bow. The disadvantage of the crossbow is that it takes longer to load and six to seven arrows can be shot by a longbow in the minute it takes to load the crossbow. The extended range of the crossbow explains its appeal. Compared to the longbow, which can shoot about 280 feet (255 meters), the crossbow can cover approximately 380 yards (360 meters). At tactical range, both weapons can pierce pla
