Abstract: The subject disclosure relates to systems and methods for improving multicast traffic flows in a computer network. In some aspects, a method of the technology includes steps for receiving multicast traffic statistics from each of a plurality of switches in a computer network, aggregating the multicast traffic statistics into a time-series database, and identifying a low-performing multicast flow based on the time-series database. In some aspects, the method can include steps for automatically reconfiguring the computer network to improve the low-performing multicast flow. Systems and machine readable media are also provided.

Abstract: A network device receives data packets and derives a key from headers in the packets. A search engine in the device searches, or performs a table lookup, for information based on the key and multiple programmable masks. The search engine includes a hash based search engine that comprises multiple mask modules each to mask an input key with a respective programmable mask, to produce multiple masked keys. The search engine also includes an array of hash modules each corresponding to a respective one of the masked keys and including a hash table. Each of the hash modules searches its hash table for a data value based on a hash of the corresponding masked key, and outputs a found data value, if any, resulting from the search. A selector selects among the found data values and output the selected data value.
Abstract translation: 一个网络设备接收数据包，并从包中的头中导出一个密钥。 设备中的搜索引擎基于密钥和多个可编程掩码来搜索或执行表查找信息。 搜索引擎包括基于哈希的搜索引擎，其包括多个掩模模块，每个掩模模块用相应的可编程掩码掩蔽输入密钥，以产生多个掩蔽密钥。 搜索引擎还包括散列模块的阵列，每个散列模块对应于相应的一个掩蔽密钥并且包括哈希表。 每个散列模块基于相应的屏蔽密钥的散列来搜索其散列表中的数据值，并输出从搜索结果得到的找到的数据值（如果有的话）。 选择器在所找到的数据值中进行选择并输出所选择的数据值。
