Abstract: A parsing apparatus includes a packet-type identification circuit and a parser. The packet-type identification circuit is to receive a packet to be parsed, and to identify a packet type of the packet by extracting a packet-type identifier from a defined field in the packet. The parser is to store one or more parsing templates that specify parsing of one or more respective packet types. When the packet type of the packet corresponds to a parsing template among the stored parsing templates, the parser is to parse the packet in accordance with. the stored parsing template. When the packet type of the packet does not correspond to any of the stored parsing templates, the parser is to parse the packet using an alternative parsing scheme.

Abstract: A network device includes multiple ports, packet processing circuitry, a memory and a reserved-memory management circuit (RMMC). The ports are to communicate packets over a network. The packet processing circuitry is to process the packets using a plurality of queues. The memory is to store a shared buffer. The RMMC is to allocate segments of the shared buffer to the queues, including allocating reserve segments of the shared buffer to selected queues that meet a reserve-allocation criterion.

Abstract: Devices, methods, and systems are provided. In one example, a device is described to include a bandwidth-constrained resource and a controller that dynamically allocates a proportional consumption of storage to the bandwidth-constrained resource thereby enabling the bandwidth-constrained resource to provide bandwidth to a consuming entity. The controller may allocate the proportional consumption of the storage to the bandwidth-constrained resource based on a current state of the bandwidth-constrained resource.

Abstract: A method in a network element that includes multiple interfaces for connecting to a communication network includes receiving from the communication network via an ingress interface a flow including a sequence of packets, and routing the packets to a destination of the flow via a first egress interface. A permission indication for re-routing the flow is received in the ingress interface. In response to receiving the permission indication, subsequent packets of the flow are re-routed via a second egress interface that is different from the first egress interface. Further re-routing of the flow is refrained from, until receiving another permission indication.

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: Methods and systems are disclosed for network congestion management. The methods and systems receive a first packet complying with a first network protocol comprising a first congestion indicator representative of a presence or absence of network congestion and further comprising a first set of data associated with a second network protocol, and provide an indication of the presence or absence of network congestion generated based, at least in part, on the first congestion indicator. The methods and systems also receive a first packet complying with a first network protocol comprising a first set of data associated with a second network protocol, and output a second packet complying with the first network protocol comprising a first congestion indicator representative of a presence of network congestion.

Abstract: An example method for dynamic packet routing using prioritized groups includes: receiving, by a node, a network packet to be forwarded to a network destination, identifying, based on data stored in a forwarding information data structure of the node, a first path satisfying a first cost criterion to the network destination, determining that a path latency of the first path exceeds a threshold latency, selecting, based on the data stored in the forwarding information data structure of the node, a second path to the network destination, wherein the second path satisfies a second cost criterion and does not satisfy the first cost criterion, and forwarding, by the node, the network packet to the network destination via a local interface associated with the second path.

Abstract: An example method for dynamic packet routing using prioritized groups includes: receiving, by a processing device, routing information specifying a plurality of paths to a network destination, wherein each path is associated with a respective cost metric value; associating a first subset of the plurality of paths with a first priority routing group for the network destination, wherein each path of the first subset satisfies a first cost criterion based on a cost metric value of the path; associating a second subset of the plurality of paths with a second priority routing group for the network destination, wherein each path of the second subset satisfies a second cost criterion; and storing, in a forwarding information data structure, a first definition of the first priority routing group and a second definition of a second priority routing group.
