Web提出一种增强IPv6网络BGP路由聚合能力的方法.该方法建议将Provider Independent(PI)地址空间的前缀映射为PA地址空间中相应大小的地址块,然后宣告BGP路由.该方法需要在AS边缘路由器(ASBR)建立前缀置换映射表.必要时采用前缀映射置换的方法处理进出AS的IPv6分组.该方法仅在AS边缘路由器部署,不影响域内路由 ... In symmetric key cryptography, both parties must possess a secret key which they must exchange prior to using any encryption. Distribution of secret keys has been problematic until recently, because it involved face-to-face meeting, use of a trusted courier, or sending the key through an existing encryption channel. The first two are often impractical and always unsafe, while the third depends on the security of a previous key exchange. sweat suit how to wear
