Abstract: A network device includes one or more ports, a packet processor, and a memory management circuit. The one or more ports are to communicate packets over a network. The packet processor is to process the packets using a plurality of queues. The memory management circuit is to maintain a shared buffer in a memory and adaptively allocate memory resources from the shared buffer to the queues, to maintain in the memory, in addition to the shared buffer, a shared-reserve memory pool for use by a defined subset of the queues, to identify in the subset a queue that (i) requires additional memory resources, (ii) is not eligible for additional allocation from the shared buffer, and (iii) meets an eligibility condition for the shared-reserve memory pool, and to allocate memory resources to the identified queue from the shared-reserve memory pool.

Abstract: Technologies for bi-directional encryption and decryption for underlay and overlay operations are described. One network device includes multiple ports, a network processing element, a programmable path-selection circuit, and a security IC. The programmable path-selection circuit is configured to operate in a first mode in which first outgoing packets are routed to the security integrated circuit to be encrypted before sending on one of the ports, and first incoming packets, received on one of the ports, are routed to the security integrated circuit to be decrypted. The programmable path-selection circuit is configured to operate in a second mode in which second incoming packets are routed to the security integrated circuit to be encrypted before processing by the network processing element and route second outgoing packets to the security integrated circuit to be decrypted after processing by the network processing element.

Abstract: A method for communication includes configuring a router to forward data packets over a network in accordance with Multiprotocol Label Switching (MPLS) labels appended to the data packets. At least first and second entries, corresponding to respective first and second labels, are stored in a Next Hop Label Forwarding Entry (NHLFE) table in the router, such that each of the first entries contains a respective pointer to at least one of the second entries. Upon receiving in the router a data packet from the network, a first entry is selected from among the first entries in the NHLFE table and, responsively to the pointer in the first entry, a second entry is selected. The respective first and second labels from the selected first and second entries are pushed onto an MPLS label stack of the data packet.

Abstract: A network element includes circuitry and one or more interfaces. The interfaces are configured to connect to a communication network. The circuitry is configured to assign multiple egress interfaces corresponding to respective different paths via the communication network for routing packets to a given destination-address group, to hold, for the given destination-address group, respective state information for each of multiple sets of hash results, to receive via an ingress interface a packet destined to the given destination-address group, to calculate a given hash result for the packet and identify a given set of hash results in which the given hash result falls, and to forward the packet via one of the multiple egress interfaces in accordance with the state information corresponding to the given destination-address group and the given set of hash results.

Abstract: A method in a communication network includes defining a root congestion condition for a network switch if the switch creates congestion in the network while switches downstream are congestion free, and a victim congestion condition if the switch creates the congestion as a result of one or more other congested switches downstream. A buffer fill level in a first switch, created by network traffic, is monitored. A binary notification is received from a second switch, which is connected to the first switch. A decision whether the first switch or the second switch is in a root or a victim congestion condition is made, based on both the buffer fill level and the binary notification. A network congestion control procedure is applied based on the decided congestion condition.

Abstract: A system, a computing system, and a switch are provided. In one example, a system for routing data to one of a plurality of queues comprises a processor to poll a depth of one or more queues of the plurality of queues, determine a weight for each polled queue based on the depth of each polled queue, and route data received via a port to a first queue of the plurality of queues based on the determined weight for each polled queue.

Abstract: Networking devices, systems, and methods are provided. In one example, a method includes receiving a packet at a networking device; evaluating the packet; based on the evaluation of the packet, truncating the packet from a first size to a second size that is smaller than the first size; and storing the truncated packet in a buffer prior to transmitting the truncated packet with the networking device.
