  • Patent number: 11729166
    Abstract: Some embodiments provide a method, executable by a network device, that receives a first set of commands instructing the network device to allow network traffic to egress out of an authentication port of the network device. The authentication port is configured to belong to a first virtual local area network (VLAN). An unauthenticated device is connected to the authentication port. The method further receives a second set of commands instructing the network device to add ports belonging to the first VLAN to a broadcast domain of a second VLAN. The method also broadcasts an address request to the broadcast domain of the second VLAN. The method further receives, from the unauthenticated device, a response to the address request.

  • Publication number: 20230043464
    Abstract: The present disclosure relates to methods and devices for performing depth estimation on image data. In one example, a device performs depth estimation on first and second images captured using one or more cameras having a color filter array. Each, image of the first and second images comprises multiple color channels. Each color channel of the multiple color channels corresponds to a respective color channel of the color filter array. The, device performs the depth estimation by estimating disparity from the color channels of the first and second images.

  • Patent number: 9338172
    Abstract: A method for authenticating an Internet Protocol Security (IPsec) packet, wherein the method comprises, receiving the IPsec packet via an input port, performing a Sequence-Integrity Check Value (SEQ-ICV) check that validates a sequence number within the IPsec packet, and performing an Integrity Check Value (ICV) check that validates a checksum within the IPsec packet, wherein the SEQ-ICV check is performed before the ICV check. In yet another example embodiment, an apparatus for transmitting an IPsec packet, comprising a processor, and a transmitter coupled to the processor, wherein the transmitter is configured to transmit an IPsec packet that comprises a header that comprises a sequence number field that provides a sequence number, and a payload that comprises one or more SEQ-ICV segments used to authenticate the sequence number within the IPsec packet.

  • Patent number: 9021577
    Abstract: A network element (NE) comprising a memory device configured to store instructions, and a processor configured to execute the instructions by dividing a first plurality of data packets of a data flow into a first plurality of sub-flows, and causing the first plurality of sub-flows to be transmitted to a second NE via a network, wherein the first plurality of sub-flows are transmitted using a first Internet Protocol Security (IPsec) security association (SA) cluster comprising a plurality of parallel sub-SAs. The disclosure also includes a NE comprising a processor configured to create an IPsec SA cluster comprising a first plurality of sub-SAs between the NE and a second NE using an internet key exchange (IKE) or an IKEv2, wherein the first sub-SAs are unidirectional, and wherein the first sub-SAs are configured to transport a first plurality of data packets in a common direction.

  • Publication number: 20080005349
    Abstract: A media content distribution system for distributed multimedia streaming communicates over a network and incorporates multiple independent media stations, each having a media director for control and a number of media engines for storage, retrieval and streaming of media content. A content request from a media console connected to the network is redirected by the media director to a selected one of the media engines storing content corresponding to the request for streaming. Statistical indicators are defined for measuring effectiveness of the content distribution network. Push and pull indicators with additional differentiation for remote and local access to pulled content provide means for efficiency determination of data distribution and storage. A middleware Application Programming Interface (API) structure is provided for flexible interfacing between media consoles and content distribution system components.
