摘要： Subject matter described herein includes a multi-layer search-engine index. Accordingly, the search-engine index is divided into multiple indexes, each of which includes a respective set of information used to serve (i.e., respond to) a query. One index includes a term index, which organizes a set of terms that are found among a collection of documents. Another index includes a document index, which organizes a set of documents that are searchable. A computing device is used to serve the search-engine index (i.e., to analyze the index when identifying documents relevant to a search query). For example, a solid-state device might be used to serve the multi-layer search-engine index.

摘要： Described is looking up network information (e.g., port data) on demand upon receiving a (e.g., DHCP) request packet containing a MAC address. The MAC address may be looked up in a cache to find the port data. If not cached or cached but outdated, the lookup continues via a querying process that finds the relevant switch containing the port data; the cache is updated based on the querying process result. Successful querying results in a valid cache entry, while unsuccessful querying results in an invalid entry. For port data associated with the MAC address found via the cache or via querying, the port data is used to respond to the request packet, e.g., to assign an IP address to a network device corresponding to that MAC address. For a MAC address determined to be invalid via the cache or via querying, the request is rejected.
摘要翻译：描述了在接收到包含MAC地址的（例如DHCP）请求分组时，根据需要查找网络信息（例如，端口数据）。可以在缓存中查找MAC地址以查找端口数据。如果没有缓存或缓存但过时，则通过查询过程继续查找查找包含端口数据的相关交换机; 基于查询过程结果更新缓存。成功查询会导致有效的缓存条目，而查询失败会导致无效条目。对于与通过高速缓存或通过查询找到的MAC地址相关联的端口数据，端口数据用于响应请求分组，例如为与该MAC地址相对应的网络设备分配IP地址。对于通过缓存确定为无效的MAC地址或通过查询，请求被拒绝。

摘要： Techniques are described for managing failover in redundant network devices. In particular, each device in a set of redundant network devices includes redundant processing modules. Each module provides a separate operating environment for a set of network services. Each network device includes a control unit that receives configuration information that specifies individual weight values for each of the modules and a threshold value for the network device. The control unit detects failures of the modules and transfers primary responsibility for performing the network service to a second network device when the threshold value is exceeded by a weighted sum of the weight values for the failed modules.
