摘要： A device may receive, from a first device, a port control protocol (PCP) request that includes a customer side translator (CLAT) prefix and one or more private internet protocol version X (IPvX) addresses. The PCP request may be received via an internet protocol version Y (IPvY) network. The device may store the CLAT prefix and the one or more private IPvX addresses using a data structure. The device may receive a packet that includes a private IPvX of the one or more private IPvX addresses and a private IPvY address that includes the CLAT prefix and a second instance of the private IPvX address. The device may use an application layer gateway (ALG). The device may translate the private IPvX address to a public IPvX address using the CLAT prefix. The device may provide the packet that includes the public IPvX address to a second device that supports IPvX.

摘要： A method for indicating a use of an illicit IP address in a local communication network connected to a wide area communication network by a router, the method including: receiving a packet from at least one device in the local communication network using an illicit IP address; generating an error message marked with a predefined mark; sending the marked error message to the at least one device using an additional routing table redirecting each packet to the local communication network and a routing rule applying the additional routing table to each packet marked with the predefined mark.

摘要： Described herein are methods and systems for generating a mobile device-specific identifier usable across native mobile applications and mobile browsers with a unified opt-out mechanism. A mobile device generates a transient identifier for the mobile device and maps the transient identifier to a stable identifier of the mobile device using at least one call to a service endpoint coupled to the mobile device via a communications network. A browser application on the mobile device renders a webpage, the webpage comprising first instructions, executed by the browser application, to retrieve the stable identifier of the mobile device using at least one call to the service endpoint coupled to the mobile device via a communications network.

摘要： A method performed by a WTRU may comprise receiving context information from infrastructure equipment and selecting a SLAP quadrant for MAC address allocation. The selecting may be based on the context information received from the infrastructure equipment, which may be a bootstrapping server for the WTRU. The method may further comprise transmitting, to a DHCP server, a DHCP message indicating the selected SLAP quadrant. In response to the transmitted DHCP message, a MAC address may be received and configured to the WTRU. Context information includes, but is not limited to, a number of nodes in a network, a type of network deployment, a type of network, a mobility configuration, a type of device management, a battery lifetime, a location or privacy configuration.

摘要： A controller determines a first path across a first segment routing (SR) domain and a second SR domain to a destination in the second SR domain, where the first SR domain uses a first SR protocol and the second SR domain uses a second SR protocol. The controller determines SR instructions that enable the interworking of the first SR domain and the second SR domain when data is routed across the first path to the destination. The controller sends, prior to the data being routed over the first path, the SR instructions to at least one of a first router in the first SR domain, a second router in the second SR domain, or a third router in the first SR domain to enable the interworking of the first and the second SR domains for segment routing the data across the first path.

摘要： In one embodiment, Ethernet Virtual Private Network (EVPN) is implemented using Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) underlay network and SRv6-enhanced Border Gateway Protocol (BGP) signaling. A particular route associated with a particular Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) Segment Identifier (SID) is advertised in a particular route advertisement message of a routing protocol (e.g., BGP). The SID includes encoding representing a particular Ethernet Virtual Private Network (EVPN) Layer 2 (L2) flooding Segment Routing end function of the particular router and a particular Ethernet Segment Identifier (ESI), with the particular SID including a routable prefix to the particular router. The particular router receives a particular packet including the particular SID; and in response, the particular router performs the particular EVPN end function on the particular packet.

摘要： An apparatus includes a processing device configured to receive a request to change a given storage network from a first to a second configuration, the given storage network being associated with a heterogeneous storage cluster comprising a plurality of storage targets and initiators having first network addresses in the first configuration. The processing device is also configured to generate a shadow storage network comprising second network addresses having the second configuration, to assign the second network addresses to a subset of a plurality of storage targets and initiators affected by the request to change the given storage network from the first to the second configuration, and, responsive to validating connectivity of the subset of the plurality of storage targets and initiators, to apply the requested change by unassigning ones of the first network addresses assigned to the subset of the plurality of storage targets and initiators.

摘要： Methods and systems for a device identification system may be provided. The device identification system may determine an identity of a user device associated with a transaction. The identity may be determined by network address information, hard link information, soft link information, and/or other such information. The network address information may include IPv4 information, IPv6 information, a device ID, and/or other such information. The identity of the user device may be determined and a transaction conducted from the user device may be assigned a fraudulent transaction risk score according to the information. Transactions that are determined to be at a high risk of fraud may be reviewed or otherwise flagged and/or canceled.

摘要： A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

摘要： Disclosed are various embodiments for managing network address allocations using prefix allocation trees. In one embodiment, a request is received to allocate a particular network address block. The request specifies one or more attributes and at least one of a prefix or a size for the particular network address block. A prefix allocation tree is updated to indicate that the particular network address block corresponding to the prefix is allocated instead of free and to associate the attribute(s) with the particular network address block. An identification of an allocation of the network address block is returned in response to the request to allocate the particular network address block. An attribute index of the prefix allocation tree is updated asynchronously to index the attribute(s) in association with the particular network address block.
