Abstract: Examples described herein relate to a switch comprising: circuitry, when operational, to receive a packet comprising a header and a payload and in conjunction with performance of computation on the packet payload, forward the packet header, but not the payload, to a destination endpoint. In some examples, the destination endpoint of the packet is to perform management of reliable transport. In some examples, the circuitry includes programmable data plane circuitry comprising ingress pipeline or egress pipeline and one or more match action units (MAUs) to perform processing of the payload, wherein the programmable data plane circuitry is to perform computation on the packet payload.

Abstract: Examples described herein relate to a switch circuitry that includes circuitry to cause transmission, to multiple destinations, of copies of a packet received from a sender network interface device and circuitry to indicate acknowledgement of packet receipt, from the multiple destinations, to the sender network interface device based on receipt of acknowledgements of packet receipt from the multiple destinations. In some examples, the circuitry is to indicate acknowledgement of packet receipt, from the multiple destinations, to the sender network interface device with a packet index value.

Abstract: An improved system for simplifying a complex waveguide network in a satellite system is described herein. A waveguide network device may be configured with at least two housing portions attached together. This enables the waveguide network device to receive an arbitrary number of waveguide routes and output the routes in any configuration, effectively simplifying the overall waveguide network architecture.

Abstract: Some embodiments of the invention provide a data plane circuit for a network forwarding element that searches for one or more patterns of characters stored in data messages received by the data plane circuit. In some embodiments, the data plane circuit analyzes the data messages as it processes the data messages to forward the data messages to their destinations in a network. Because the data messages are already flowing through the network, it is optimal to search the data messages for the character patterns as the data messages pass through the network, instead of performing these operations on a separate set of servers that typically perform these searches at slower rates. In other embodiments, the data plane circuit does not perform its character pattern searches in conjunction with its forwarding operations, as it receives the data messages from a set of servers just for the purpose of performing its character pattern searches, in order to offload some or all of these searches from the server set.

Abstract: According to one example embodiment, an EID-NOTIFY packet is defined for use with the Location/Identifier Separation Protocol (LISP). A first-hop network element may send EID-NOTIFY responsive to decoding a data packet from a previously undetected host on its subnetwork. A site network element may receive EID-NOTIFY, and send a MAP-REGISTER message to a mapping system. EID-NOTIFY may have substantially the same format as MAP-NOTIFY. This may enable the site network element to be removed more than one hop from the subnetwork.

Abstract: A method is provided in one example embodiment and it includes receiving a first plurality of packets from an active stream at an output device and communicating the first plurality of packets to a next destination. The method also includes receiving a second plurality of packets from a standby stream of the output device, the streams are sent by an input device. The method further includes performing a switchover at the output device such that the second plurality of packets is communicated to the next destination and the first plurality of packets is not. The switchover is triggered when a portion of the first plurality of the packets from the active stream is not received during a period of time that is greater than a majority of inter-arrival times of the second plurality of packets on the standby stream.
