Various example embodiments for supporting multicast are presented herein. Various example embodiments for supporting stateless multicast may be configured to support stateless multicasting of packets based on encoding of multicast path information within the packets. Various example embodiments for supporting stateless multicasting of packets based on encoding of multicast path information within the packets may be configured to use a recursive scheme of encoding the multicast path information within the packets such that the header that arrives at each node of the multicast path informs the node of the outgoing links over which the packet is to be sent and the headers to be sent on the outgoing links (e.g., each node of the multicast tree is able to recognize each of its outgoing links from the received header and send the appropriate subtree encoding down each of its outgoing links).

Stateless and secure packet forwarding

The present disclosure generally discloses an Internet security mechanism configured to provide security for Internet resources of the Internet using an Internet blockchain. The Internet blockchain may be configured to provide security for Internet resources of the Internet by supporting various types of verification related to Internet resources of the Internet, which may include verification of Internet resource ownership, verification of Internet resource transactions, and so forth. The Internet blockchain may be configured to enable Internet participants (e.g., Internet registries, Domain Name Service (DNS) entities, Autonomous Systems (ASes), or the like) to verify Internet resource ownership of Internet resources (e.g., Internet Protocol (IP) addresses, AS numbers, IP prefixes, DNS domain names, or the like) by Internet participants, to verify Internet resource transactions (e.g., allocation of IP addresses, allocation of AS numbers, advertisements of IP prefixes, allocation of DNS domain names, or the like) attempted by Internet participants, and so forth.

A method for controlling packet routing in a network includes identifying segment identifications (IDs) for a number of switches and arranging a first number of the segment IDs into a multi-protocol label switching (MPLS) label field. The method further includes identifying an output port of a respective one of the number of switches located along a network path between source and destination nodes. The switches may route the packet based on corresponding ones of the segment IDs in the MPLS label field. In performing this routing operation, each switch may modify the MPLS label field with remaining ones of the segment IDs that have been shifted in position and padded with zeros, after the segment ID corresponding to the switch has been popped from the MPLS label field. The method therefore presents a technique for performing segment routing through network equipment designed to support MPLS routing.

Various embodiments relate to a method for accelerating blockchains, the method comprising the steps of waiting for an event to occur, receiving a block, determining whether the block is valid, adding the block to a block tree, determining whether the block is a singular candidate, starting a timer for the block, determining whether the timer has expired for the block, determining whether the block is still singular after the time has expired for the block and processing the singular block.

A resource assignment capability is presented. A resource specification associated with a plurality of elements is received. The resource specification includes, for each of the elements, a resource request including an indication of a quantity of resources requested by the element and a resource offer including an indication of a quantity of resources offered by the element for use by one or more other elements. A resource assignment, including an indication of an association between the resources requests and the resource offers, is determined using a resource assignment process. The resource assignment process may be a greedy assignment process or a maximum flow resource assignment process. The maximum flow resource assignment process includes constructing a maximum flow resource graph based on the one or more resource specifications and applying a maximum flow process to the maximum flow resource graph to determine thereby the resource assignment.

Apparatus and method for matching offers and requests for sharing of resources

Various embodiments relate to a method, device, and machine-readable storage medium including: instructions for receiving a configuration request from an edge device, wherein the configuration request identifies a traffic flow between at least two end devices other than the edge device; instructions for assigning a virtual local area network (VLAN) identifier to the traffic flow; instructions for configuring the edge device to add the assigned VLAN identifier to outgoing frames associated with the traffic flow, wherein the outgoing frames are frames that will be transmitted by the edge device to a core network. Various embodiments additionally include instructions for configuring, in response to assigning the VLAN identifier, at least one additional edge device to remove the VLAN identifier from incoming frames associated with the traffic flow, wherein the incoming frames are frames that have traversed at least one core node of the core network.

In general, a capability for forwarding packets based on path encoding is presented. The capability for forwarding a packet based on path encoding may be configured to enable forwarding of a packet along a network path by determining a path encoding label for the network path, associating the path encoding label for the network path with the packet, and forwarding the packet along the network path based on the path encoding label associated with the packet. The network path for a packet may include an ordered sequence of node output interfaces of an ordered sequence of nodes. The path encoding label for the network path includes an ordered sequence of node interface labels corresponding to the ordered sequence of node output interfaces of the nodes of the network path. The nodes of the network path forward the packet along the network path based on the path encoding label.

An illustrative example surveillance system designed according to an embodiment of this invention includes a plurality of cells that respectively include a surveillance network including at least one detector that is configured to detect at least one type of subject. The cells have respective detection areas within which a subject may be detected by the at least one detector of that cell. A controller of the cell determines information regarding tracking of a detected subject that is in that cell. The controller hands off tracking of the subject to a second one of the cells based upon an indication that the tracked subject is moving toward the detection area of the second one of the cells.

A managed Universal Serial Bus (USB) service capability is disclosed. The managed USB service capability is configured to use a mobile computing device (e.g., a smartphone or other suitable mobile computing device) to support a set of services for a computer (e.g., a desktop, a laptop, and the like) capable of connecting to the mobile computing device via a USB connection. The managed USB service capability enables local and/or remote control of the mobile computing device to operate in various USB device classes, such that the mobile computing device can provide various managed USB services for the computer via the peripheral connection. In this manner, the mobile computing device may be dynamically configured to operate as one or more of a network interface, a virtual private network (VPN) client, a smart card, a serial console, a mass-storage device, a booting device, and the like.

Overload control in a cloud computing environment

A mobile node includes a processor, a network interface, and a storage device having computer program code for execution by the processor. The computer program code includes a network layer for transmitting and receiving packets and an intermediate driver that transmits packets to the network layer and receives packets from the network layer using a virtual interne protocol (IP) address to identify the mobile node. The intermediate driver transmits packets to the network interface and receives packets from the network interface using a routable actual IP address to identify the mobile node. The intermediate driver permits the actual IP address to change when the mobile node moves from a first subnet to a second subnet without a corresponding change in the virtual IP address. A corresponding NAT associates the virtual IP address with a second actual IP address when the NAT is notified that the mobile node is in the second subnet.
