Stream-based data deduplication with peer node prediction
Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers. |

Systems and methods for running network egress links with small buffers at a high utilization
Methods and systems for managing packet flow in a local network in a manner that allows network devices at the edge of the network to use minimal buffer memory while maximizing use of bandwidth allocated on an interconnect between the local network and an external network.

Aggregate energy consumption across a network
This disclosure relates to determining aggregate energy consumption associated with sending content (e.g., media content, such as a video file, audio file, etc.) across a network. For example, node 106A receives a network packet from server 104 and forwards the packet to node 106B. Node 106A determines an amount of energy consumed by node 106A in processing the packet. Node 106A adds this determined energy consumption value to an energy consumption value in a header within the network packet to produce an aggregate energy consumption value and send the network packet with the aggregate energy consumption value to node 106B. Node 106B receives the network packet from node 106a. Node 106B determines an amount of energy consumed by node 106B in processing the packet. Node 106B adds this determined energy consumption value to the energy consumption value in the header within the network packet to produce an aggregate energy consumption value and send the network packet with the aggregate energy consumption value to node 106G. Node 106G also adds its determined energy consumption to the aggregate energy consumption value received from node 106B. Node 106G sends the packet with the further updated aggregate energy consumption value to communication device 102. After communication device 102 receives the packet, a process running on communication device 102 extracts and stores the aggregate energy consumption value. When communication device 102 receives another packet related to the first packet, communication device 102 extracts, from this second packet, the aggregated energy consumption and sums this new aggregated energy consumption value with the stored aggregated energy consumption value in order to determine a total energy consumption. Thus, the present disclosure provides for determining an aggregate energy consumption value as well providing users of a network with information that makes them aware of how much energy is being consumed to transmit and/or receive content through the network. The energy consumption value for network nodes that cannot determine the amount of energy needed to send one or more network packets may be estimated. |

Certificate status delivery through a local endpoint
Techniques are disclosed for locally distributing online certificate status protocol (OCSP) responses to a client computer. A certificate authority (CA) proactively sends OCSP responses to an agent application (e.g., an antivirus application configured to handle OCSP responses) residing in the client computer.

Pulsed laser diode drivers and methods
A current driver is disclosed which allows very short pulses at high currents to be generated for high power laser diodes. The parasitic inductance of the laser diode limits the speed at which the laser diode may be turned on and off. A high voltage is used to charge this inductance rapidly and maximize the rise time. The fall time is shortened by allowing a similar high voltage to be generated at turnoff without damage to the laser diode or switching components. A portion of the energy stored in the parasitic inductance may recovered to reduce drain on the power source, and to improve overall efficiency. The anode of the laser may be switched to ground at the end of a pulse. |

Slab laser and amplifier
A laser for high power applications. The laser is a lamp driven slab design with a face to face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface. Also presented is a side to side larger amplifier configuration, permitting very high average and peak powers due to the electrical efficiency of absorbing energy into the crystal, optical extraction efficiency, and scalability of device architecture. Cavity filters adjacent to pump lamps convert the unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power. |
