Phonepl has a hardware-independent abstraction of this feature so that it allows programmers mostly unconscious of this hardware feature. To
\nimplement the abstraction, four representations of packet data type that cover all the packet operations (including substring, concatenation, input, and output) are  ntroduced. Phonepl have been implemented on Octeon NPs used in plug-ins for a network-virtualization environment called the VNode Infrastructure, and several packet-handling programs were evaluated. As for the evaluation result, the conversion throughput is close to the wire rate, i.e., 10 Gbps, and no packet loss (by cache miss) occurs when the packet size is 256 bytes or larger. \u4e0b\u9762\u662f\u5904\u7406IPv4 MAC\u5305\u5934\u7684\u4ee3\u7801\uff0c\u5f88\u7b80\u6d01\u3002\u5176\u4e2dsubstring\u662f\u6539\u5199\u8fc7\u7684\u7cfb\u7edf\u51fd\u6570\u3002<\/font><\/p>\n
