摘要： Communication apparatus includes multiple interfaces connected to a packet data network. A memory is coupled to the interfaces and configured as a buffer to contain packets received through ingress interfaces while awaiting transmission to the network via respective egress interfaces. Packet processing logic is configured, upon receipt of a multicast packet through an ingress interface, to identify a number of the egress interfaces through which respective copies of the multicast packet are to be transmitted, to allocate a space in the buffer for storage of a single copy of the multicast packet, to replicate and transmit multiple copies of the stored copy of the multicast packet through the egress interfaces, to maintain a count of the replicated copies that have been transmitted, and when the count reaches the identified number, to release the allocated space in the buffer.

摘要： A computing method includes specifying a virtual computer system including at least one virtual or physical compute node, which produces data packets having respective source attributes. At least one Virtual Input-Output Connection (VIOC) that is uniquely associated with the values of the source attributes is defined. A policy specifying an operation to be performed with regard to the VIOC is defined. The virtual computer system is implemented on a physical computer system, which includes at least one physical packet switching element. The physical packet switching element is configured to identify the data packets whose source attributes have the values that are associated with the VIOC and to perform the operation on the identified data packets, so as to enforce the policy on the VIOC.

摘要： A method for data-center management includes, in a data center including multiple components, monitoring a plurality of performance measures of the components. A set of composite metrics is automatically defined, each composite metric including a respective weighted combination of two or more performance measures from among the performance measures. Baseline values are established for the composite metrics. An anomalous deviation is detected of one or more of the composite metrics from the respective baseline values.

摘要： An optical device includes a chip, a set of waveguides on the chip and configured to carry first optical signals modulated with data during a data transmission stage, and an alignment waveguide on the chip. The alignment waveguide is configured to receive a second optical signal during an alignment stage that aligns the set of waveguides with a collimator including a set of lenses. The alignment waveguide is configured to output the second optical signal from the chip. The second optical signal output from the chip is indicative of a quality of alignment between the set of waveguides and the collimator.
