Abstract: An printed circuit board (PCB) assembly and method of assembling the same for a high-speed, short-reach communication link are described that provide a mechanism for transmitting radio frequency (RF) waves from one digital electronic component of the PCB assembly to another, where the second digital electronic component is located either on the same PCB assembly or on a second PCB assembly. The assembly includes a PCB having multiple layers and a digital electronic component supported by the PCB. At least one of the layers defines a channel that confines RF waves therein. An RF antenna in communication with the digital electronic component extends into the channel, and the RF antenna transmits RF signals generated by the digital electronic component into the channel as RF waves or receives RF waves via the channel and conveys corresponding RF signals to the digital electronic component.

Abstract: A network element includes multiple ports and packet processing circuitry. The ports are configured for exchanging packets with a communication network. The packet processing circuitry is configured to forward first packets over a forward path from a source node to a destination node, to forward second packets over a reverse path, which is opposite in direction to the forward path, from the destination node to the source node, and to mark one or more of the second packets that are forwarded over the reverse path, with an indication that notifies the source node that congestion is present on the forward path.

Abstract: A method in a network element includes processing input packets using a set of two or more functions that are defined over parameters of the input packets. Each function in the set produces respective interim actions applied to the input packets and the entire set produces respective end-to-end actions applied to the input packets. An end-to-end mapping, which maps the parameters of at least some of the input packets directly to the corresponding end-to-end actions, is cached in the network element. The end-to-end mapping is queried with the parameters of a new input packet. Upon finding the parameters of the new input packet in the end-to-end mapping, an end-to-end action mapped to the found parameters is applied to the new input packet, without processing the new input packet using the set of functions.

Abstract: A method in a network element that includes multiple interfaces for connecting to a communication network includes receiving via an ingress interface packets that are not allowed to undergo re-routing and that are addressed to a destination via a first egress interface. The packets are forwarded via the first egress interface when there is a valid path from the first egress interface to the destination. When there is no valid path from the first egress interface to the destination, a second egress interface is selected from a group of multiple egress interfaces that have respective paths to the destination and are assigned to packets for which re-routing is allowed, and the packets are forwarded via the second egress interface until recovering a path to the destination.

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 method for communication, includes routing unicast data packets among nodes in a network using respective Layer-3 addresses that are uniquely assigned to each of the nodes. Respective Layer-2 unicast addresses are assigned to the nodes in accordance with an algorithmic mapping of the respective Layer-3 addresses. The unicast data packets are forwarded within subnets of the network using the assigned Layer-2 addresses.

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 switching apparatus includes multiple ports, each including a respective buffer, and a switch controller. The switch controller is configured to concatenate the buffers of at least an input port and an output port selected from among the multiple ports for buffering traffic of a long-haul link, which is connected to the input port and whose delay exceeds buffering capacity of the buffer of the input port alone, and to carry out end-to-end flow control for the long haul link between the output port and the input port.
