摘要： Introduced here are network visibility platforms having total processing capacity that can be dynamically varied in response to determining how much network traffic is currently under consideration. A visibility platform can include one or more network appliances, each of which includes at least one instance of an application configured to process data packets. Rather than forward all traffic to a single application instance for processing, the traffic can instead be distributed amongst a pool of application instances to collectively ensure that no data packets are dropped due to over-congestion. Moreover, the visibility platform can be designed such that application instances are elastically added/removed, as necessary, based on the volume of traffic currently under consideration.

摘要： Various embodiments are directed to receiving, at a receiving device, a packet from a node in a first network. determining a version identifier for the packet, encoding the version identifier into the packet, and transmitting the packet containing the encoded version identifier to a load balancing device in a second network. The version identifier may be encoded into a destination port field of the packet. The receiving device may be a perimeter network address translation device. The packet is received at the load balancing device, where the version identifier is extracted and a hash of source address information is performed. The version and hash are used to select a back-end device in the second network. The packet is transmitted to the selected back-end device.

摘要： Examples relate to dynamic allocation of resources within network devices. In one example, a computing device may: receive, from a particular lookup function of a plurality of lookup functions, a lookup request for a network packet; identify, based on a logical table that corresponds to the particular lookup function, at least one physical resource included in a particular resource pool of at least one dynamic resource pool; obtain, from a particular physical resource of the at least one physical resource, response data that is responsive to the lookup request; and provide the response data to the particular lookup function.

摘要： A system and method for automated caching and tabling for finding and swapping media content is disclosed. The system and method include at least: (a) detecting, by one or more computing devices, one or more media packets transmitted over a network, wherein the one or more media packets are associated with the media content; (b) generating, by the one or more computing devices, a profile for the media content based on characteristics of the one or more media packets; (c) generating, by the one or more computing devices, a hash value based on the profile; (d) transmitting for storage in a database, by the one or more computing devices, the hash value, the profile, and the one or more media packets; (e) detecting, by the one or more computing devices, one or more subsequent media packets sent over the network and addressed to a destination to determine that the one or more subsequent media packets are associated with the media content by comparing the one or more subsequent media packets to the profile via the hash value; and (f) based on the detecting in (e) the system and method can further include transmitting, by the one or more computing devices, the one or more subsequent media packets or the one or more media packets to the destination based on a predetermined criteria.

摘要： Various example embodiments relate generally to supporting queuing of packets in a communication network. Various example embodiments for supporting queuing of packets in a communication network may be configured to support queueing of packets based on a packet queuing memory space including a hash entry space configured to maintain a set of H hash entries and a packet queue space configured to maintain a set of Q packet queues, wherein H is greater than Q. Various example embodiments for supporting queuing of packets in a communication network may be configured to support queueing of packets in a manner for handling packet events (e.g., packet arrival events, packet departure events, or the like) while preventing or mitigating queue collisions of hash entries (where a queue collision occurs when multiple hash entries, and the respective network flows of those hash entries, are associated with a single packet queue).

摘要： Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of digital content retrieval using a decentralized content fabric. In some implementations, fabric nodes of an overlay network are provided. A first fabric node is configured to: determine, responsive to a client request for a content object part, that the content object part is not stored locally at the first fabric node; identify a second one or more fabric nodes as a best match; send a network request for the content object part to the second one or more fabric nodes; obtain the content object part from the second one or more fabric nodes; and process the content object part with further content object parts to produce the digital content for the client.
