Abstract: A method for communication includes configuring a router to forward data packets in a network in accordance with MPLS labels appended to the packets. A group of two or more of the interfaces is defined as a multi-path routing group in a forwarding table within the router. A plurality of records are stored in an ILM in the router, corresponding to different, respective label IDs, all pointing to the set of the entries in the forwarding table that belong to the multi-path routing group. Upon receiving in the router an incoming data packet having a label ID corresponding to any given record in the plurality, one of the interfaces in the group is selected, responsively to the given record and to the set of the entries in the forwarding table to which the given record points, for forwarding the incoming data packet without changing the label ID.

Abstract: A communication network includes multiple nodes, which are arranged in groups such that the nodes in each group are interconnected in a bipartite topology and the groups are interconnected in a mesh topology. The nodes are configured to convey traffic between source hosts and respective destination hosts by routing packets among the nodes on paths that do not traverse any intermediate hosts other than the source and destination hosts.

Abstract: A system for distributing individual wavelength signals to different destinations. The system includes three or more optical connectors, wherein fibers connected to the three or more optical connectors carry a plurality of wavelength signals. The system also includes a device that routes a first optical signal having a first wavelength from a first optical connector to a second optical connector.

Abstract: Systems and methods herein are for global bandwidth-aware adaptive routing in a network communication and include at least one switch to determine an event associated with a change in network bandwidth between a local host and a remote host, where the at least one switch is further to provide routing protocols for the network communication, and where the routing protocols is to be used to modify an adaptive routing in the at least one switch for selection from different routes for the network communication between the local host and the remote host.

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.

Abstract: A device includes ports, a packet processor, and a memory management circuit. The ports communicate packets over a network. The packet processor processes the packets using queues. The memory management circuit maintains a shared buffer in a memory and adaptively allocates memory resources from the shared buffer to the queues, maintains in the memory, in addition to the shared buffer, a shared-reserve memory pool for use by the queues, identifies, among the queues, a queue that requires additional memory resources, the queue having an occupancy that is (i) above a current value of a dynamic threshold, rendering the queue ineligible for additional allocation from the shared buffer, and (ii) no more than a defined margin above the current value of the dynamic threshold, rendering the queue eligible for allocation from the shared-reserve memory pool, and allocates 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 a path-selection circuit that operates in a first mode or a second mode. In the first mode, the path-selection circuit receives a first incoming packet on a first port, sends it to a security circuitry to decrypt the first incoming packet to obtain a first decrypted packet, sends the first decrypted packet to a processing circuitry to process the first decrypted packet to obtain a first outgoing packet, and sends the first outgoing packet to a second port of the network device. In the second mode, the path-selection circuit receives a second incoming packet on a third port, sends it to the processing circuitry to de-encapsulate the second incoming packet to obtain a second outgoing packet, and sends the second outgoing packet to a fourth port of the network device.

Abstract: A networking device and system are described, among other things. An illustrative system is disclosed to include a packet parser and a state machine that includes a NULL header state. The packet parser references the state machine to enter the NULL header state automatically in response to parsing a packet header of a predetermined type and then, while in the NULL header state, analyzes a subsequent set of bytes without advancing a parser pointer.
