A network switch using a search engine to generate chained table lookup requests. After the search engine executes a first lookup, the next-pass logic in the search engine uses the first lookup result and information in the master key to generate a second lookup key as well as other parts of a second lookup request. A next-pass crossbar routes the second lookup request to a target memory, and the search logic executes the second lookup. The first lookup request may originate from a processing engine coupled to the search engine. The first and the second lookup results, if any, can then be returned back to the processing engine for further processing or decision making. The chain of lookups can be configured by software by specifying various operational parameters of the processing engines and the next-pass logic, including specifying a key construction mode for the second lookup.

A method of enabling access to content in a network implementing Internet Protocol version 6 (IPv6) is described, the method including accessing a content addressing file including entries each comprising a content portion location associated with the content portion. The content portion location associated with the content portion is extracted for an entry and, based on the content portion location, a section of an IPv6 address for the content portion is formed. Methods of addressing content for storage and retrieving content are also described.

Systems and methods for content aggregation creation are disclosed herein. The system can include memory having a content database and an aggregation database. The system can include a user device having a first network interface and a first I/O subsystem. The system can include a server that can: provide content to the user device via a first electrical signal; receive a selection of a portion of the provided content from the user device via a second electrical signal; automatically extract sentences from the selected portion of the provided content via a natural language processor; automatically generate a parse tree for one of the automatically extracted sentences; identify noun phrases from the part of speech tags within the parse tree; place content associated with one of the noun phrase in a content aggregation; and output the content aggregation to the user device.

A smart process control switch can implement a lockdown routine to lockdown its communication ports exclusively for use by devices having known physical addresses, enabling the smart process control switch to prevent new, potentially hostile, devices from communicating with other devices to which the smart process control switch is connected. Further, the smart process control switch can implement an address mapping routine to identify “known pairs” of physical and network addresses for each device communicating via a port of the smart process control switch. Thus, even if a new hostile device is able to spoof a known physical address in an attempt to bypass locked ports, the smart process control switch can detect the hostile device by checking the network address of the hostile device against the expected network address for the “known pair.”

A method of streaming media content over a network from a media cache node is described. The method includes receiving a request for a media content item from a client device, the request comprising an address identifying a media content item to be streamed. In response to the request, a streaming engine process is allocated to the media content item for fulfilling the request. Based on the address identifying the media content item, a location comprising a media cache node able to provide the media content item is determined and the media content item is streamed to the client device using the streaming engine process allocated to the media content item. Further methods of streaming a media content item and providing access to media content are also described.

System and method for supporting shared multicast local identifiers (MLIDs) a high performance computing environment. In accordance with an embodiment, a shared MLID range can be configured such that each subnet within a fabric can utilize an MLID within a shared MLID range without the need to utilize a TCAM, or other memory, lookup of a MGID to MLID mapping.

Systems and methods for content selection with first and second recommendation engines are disclosed herein. The system can include a memory include a content library database and a model database. The system can include a user device having a first network interface and a first I/O subsystem. The system can include one or more servers that can include a packet selection system and a presentation system. These one or more servers can: receive response data from the user device; provide received response data to a first recommendation engine; alert a second recommendation engine when a selected next node is a placeholder node; retrieve at least one statistical model relevant to selection of next node content; and select next node content based on an output of the at least one statistical model.

Systems, methods, and computer-readable media relate to providing a network management service. A system is configured to request first network information from a first component of a network using a public IP address for the first component, wherein the first network information includes private IP addresses for a second component in the network and translate, based on a mapping information for a private IP address space to a public IP address space, the private IP address for a second component to a public IP address for the second component. The system is further configured to request second network information from the second component using the public IP address and provide a network management service for the network based on the second network information.
