| 摘 要： | 三重可寻址内存（Ternary Content Addressable Memory，TCAM）能提供持续吞吐量和单一系统结构，这非常有利于实现包分类，特别是对将来基于IPv6的网络尤其如此。但是它也有缺点，比如路径有限、价格昂贵和电源消耗。为此提出了一种有效算法，对可寻址端口地址加密来减少需要的TCAM。该新方案能够将现实世界IPv6路由表的128位前缀加密成11位，并且仍然保留无类域间路由的属性。

| Abstract: | TCAM can offer sustained throughput and simple system architecture.It is attractive for packet classification,especially for the ultimate IPv6-based networks.However,it also comes with several shortcomings,such as the limited number of entries,expansive cost and power consumption.An efficient algorithm was proposed to reduce the required TCAM by encoding the address portion of the searchable entries.The new scheme could encrypt the 128-bit prefixes of the real-world IPv6 routing tables into 11 bits and still keep the property of CIDR(Classless Inter-Domain Routing). |
