摘要： A an example method includes building a dictionary between an exporter and a collector by encoding a first data record of a flow according to a dictionary template and exporting the first data record to the collector via a network communication. The method can also include compressing a second data record of the flow using the dictionary, where the compressing comprises encoding the second data record according to an encoding template; and exporting the second data record to the collector to be decompressed using the dictionary.

摘要： Various systems and methods for implementing efficient TCAM resource sharing are described herein. Entries are allocated across a plurality of ternary content addressable memories (TCAMs), with the plurality of TCAMs including a primary TCAM and a secondary TCAM, where the entries are allocated by sequentially accessing a plurality of groups of value-mask-result (VMR) entries, with each group having at least one VMR entry associated with the group, and iteratively analyzing the VMR entries associated with each group to determine a result set of VMR entries, with the result set being a subset of VMR entries from the plurality of groups of VMR entries, and the result set to be stored in the primary TCAM.
摘要翻译：本文描述了用于实现高效TCAM资源共享的各种系统和方法。条目被分配在多个三元内容可寻址存储器（TCAM）之间，多个TCAM包括主TCAM和辅助TCAM，其中条目通过顺序访问多组值掩码结果（VMR）来分配，条目，其中每个组具有与组相关联的至少一个VMR条目，并且迭代地分析与每个组相关联的VMR条目以确定VMR条目的结果集合，其中结果集是来自多个组的VMR条目的子集的VMR条目，并将结果集存储在主TCAM中。

摘要： An example method for a distributed NetFlow exporter with a single IP endpoint in a network environment is provided and includes configuring a network protocol stack of an exporter with switched virtual interface (SVI) state information of an SVI associated with a switch in a network, retrieving flow data from a NetFlow cache, and communicating the flow data to a collector according to the configured network protocol stack. Although the communication bypasses the SVI, the collector perceives the flow records as being communicated by the SVI. The SVI state information includes a public Internet Protocol (IP) address and a Media Access Control (MAC) address of the SVI, where the exporter executes on an adaptor of a server in the network. The method also includes configuring a destination IP address and a destination MAC address on the exporter according to a NetFlow policy.
摘要翻译：提供了一种在网络环境中具有单个IP端点的分布式NetFlow导出器的示例方法，并且包括使用与网络中的交换机相关联的SVI的交换虚拟接口（SVI）状态信息来配置导出器的网络协议栈，检索来自NetFlow缓存的流数据，并根据配置的网络协议栈将流数据传送到收集器。虽然通信绕过SVI，但收集者认为流记录是由SVI传达的。 SVI状态信息包括SVI的公共因特网协议（IP）地址和媒体访问控制（MAC）地址，其中导出器在网络中的服务器的适配器上执行。该方法还包括根据NetFlow策略在出口者上配置目的IP地址和目的MAC地址。
