    • According to an example embodiment, a system may include at least one processor and at least one memory comprising a policy module configured to receive data indicating risk factors associated with users of the system; update risk levels for the users by applying the data to risk factor rules; and provide the updated risk levels and/or authentication levels associated with the updated risk levels to an authentication module in response to receiving requests from the authentication module. The at least one processor and at least one memory may also comprise the authentication module configured to receive a first access request from a user; in response to receiving the first access request, request a first updated risk and/or authentication level for the user from the policy module; and require the user to provide a first authentication technique to grant the first access request based on the first updated risk and/or authentication level received from the policy module.

    • A novel compression method uses bitmaps to reduce the memory storage requirement of routing table information to about 3 MB. The data structure can be used for both route lookup and update. It does not require a separate data structure to be used for route update. A fast route lookup method is also disclosed. An efficient update method supports incremental route update. Through configuring a processor properly and developing a few customized instructions specifically for route lookup, the system can achieve more than 10 million lookups per second (MLPS) at 200 MHz. Using a configurable processor for route lookup/update provides more flexibility and extensibility which supports different data structures and lookup/update methods to meet application specific needs. The data structure and lookup method can be implemented in pure hardware in a pipelined fashion to achieve approximately 100 MLPS.
    • 一种新颖的压缩方法使用位图将路由表信息的内存存储要求减少到大约3 MB。 数据结构可用于路由查找和更新。 它不需要单独的数据结构来用于路由更新。 还公开了快速路线查找方法。 有效的更新方法支持增量路由更新。 通过正确配置处理器并开发专门用于路由查找的几条定制指令,该系统可以在200 MHz下实现每秒超过1000万次查找(MLPS)。 使用可配置的处理器进行路由查找/更新提供了更多的灵活性和可扩展性,支持不同的数据结构和查找/更新方法,以满足特定的应用需求。 数据结构和查找方法可以以流水线方式在纯硬件中实现,实现大约100MLPS。
