  • Publication number: 20250088482
    Abstract: A network device (e.g., a server, a domain name system (DNS) server, a DNS over Hypertext Transfer Protocol Secure (HTTPS) server (DoH server), a network management device, etc.) may determine a time duration, such as a time duration, based on a request for a communication session from a device. In response, the network device may determine a modified time duration for the communication session based on a type of the device, type of user associated with the device, and/or type of an application requesting the communication session.

  • Publication number: 20240235836
    Abstract: Systems, apparatuses, and methods are described for enabling user access to one or more virtual worlds and/or the user activities in the virtual worlds by use of reputation tokens. Data associated with the virtual worlds, user devices, allowed, promoted, and prohibited activities performed in the virtual worlds by the user devices, and/or other data may be stored in one or more blockchain networks, and a user may be associated with a quantity of reputation tokens based on that user's activities in the virtual world. A user may be permitted to access, communicate, interact, and transact in a virtual world based on the quantity of reputation tokens of the user satisfying a required quantity of reputation tokens.

  • Publication number: 20220353233
    Abstract: An identifier, for example, an identifier of a domain and/or a host of the domain (e.g., a fully qualified domain name (FQDN), etc.), such as a service management device (e.g., a server, a web server, a computing device, a web host device, a webpage, etc.), may be modified (e.g., hashed, encrypted, etc.) by a network device (e.g., a server, a domain name system (DNS) server, a DNS over hypertext transfer protocol secure (HTTPS) server/gateway (DoH server), DNS over Transport Layer Security (TLS) server/gateway (DoT server), a network management device, a computing device, etc.), sent to a user device (e.g., a client device, a smart device, a mobile device, a content output device, a computing device, a web browser, a search engine, etc.), and reused by the user device to request a service (e.g., a web service, a webpage, a file, content, a content item, etc.).

  • Patent number: 9479415
    Abstract: Provided are methods, non-transitory computer-readable medium, and network devices for duplicating network traffic through transparent VLAN flooding. In some implementations, a network device comprises a plurality of ports. The plurality of ports may include a first port configured as a receiving port for a VLAN configured for the network device. The plurality of ports may further include a set of ports configured as I/O ports of the VLAN. MAC learning may be disabled for the receiving port. In some implementations, the network device is configured to determine, based on contents of a packet received at the receiving port, that the packet is to be sent to one or more monitoring devices. The network device may further be configure to, upon receiving the packet at the receiving port of the VLAN, cause a copy of the packet to be sent to each of one or more I/O ports of the VLAN.

  • Patent number: 9294367
    Abstract: An approach to duplicating network traffic is described. In one approach, a method of creating multiple copies of network traffic is detailed. The method involves receiving network traffic, producing a duplicate copy of the network traffic, and forwarding the duplicate copy to a monitoring port. The monitoring port forwards copies to a number of indicated ports.

  • Patent number: 8615008
    Abstract: An approach to duplicating network traffic is described. In one approach, a method of creating multiple copies of network traffic is detailed. The method involves receiving network traffic, producing a duplicate copy of the network traffic, and forwarding the duplicate copy to a monitoring port. The monitoring port forwards copies to a number of indicated ports.

  • Publication number: 20080072081
    Abstract: A system and method for dynamically managing groups of power supplies for a computer system has a plurality of first circuits, each of the first circuits responsive to an electrical condition of each of the plurality of power sources. A second circuit is coupled to the plurality of first circuits, and is responsive to the plurality of first circuits. The second circuit identifies a state associated with any one of the plurality of power supplies. A third circuit is coupled and responsive to the second circuit. The third circuit communicates the states of the plurality of power supplies to a user.
