Embodiments may enable the communication between two IP-based devices connected to an ICN, or one IP-based device connected to an ICN network while another IP-based device is connected either to an ICN network or IP network. In an embodiment, IP packets originating from an IP-based device may be encapsulated into ICN packets and forwarded via an ICN network. In an embodiment, IP packets received via an ICN network may be encapsulated in ICN packets and forwarded to an IP-based device. In an embodiment, IP packets originating from an IP-based device may be forwarded and received via an ICN network towards another IP network. In an embodiment, IP packets received by an ICN network may be forwarded towards an IP-based device via the ICN network.

An open communication method between at least two sub-networks using a broker node. Each of the sub-networks has a different routable network addressing scheme. The method comprises receiving a packet for a specific application, the packet includes an application identifier, determining if the packet is to be relayed to another of the at least two sub-network based upon the application identifier, determining if a node receiving the packet is a broker node, relaying the packet to a broker node if not a broker node and forwarding, by the broker node, the packet to at least one node in another of the at least two sub-network. The node generating the packet is configured to communicate using a first of the at least two sub-networks. A broker node is configured for communicating using at least two of the at least two sub-network via a corresponding routable network addressing schemes for each of the sub-networks.

A network switch includes a memory configurable to store alternate table representations of an individual trie in a hierarchy of tries. A prefix table processor accesses in parallel, using an input network address, the alternate table representations of the individual trie and searches for a longest prefix match in each alternate table representation to obtain local prefix matches. The longest prefix match from the local prefix matches is selected. The longest prefix match has an associated next hop index base address and offset value. A next hop index processor accesses a next hop index table in the memory utilizing the next hop index base address and offset value to obtain a next hop table pointer. A next hop processor accesses a next hop table in the memory using the next hop table pointer to obtain a destination network address.

A server, includes a virtual machine identifier assigning section to assign an identifier of a virtual machine operating on the server; and a network interface to transmit a packet including a Layer 2 header information which includes the identifier of the virtual machine and a first packet field for a VLAN-Tag, wherein the network interface transmits the packet to a packet encapsulate section which encapsulates a second packet field including the Layer 2 header information with a virtual network identifier representing a virtual network to which the virtual machine belongs.

The invention provides a method for coupling a smart home device to a mobile terminal, comprising the following features: the smart home device (10, 20, 30) is connected to a server (40) via a source NAT router (14, 24, 34); the mobile terminal (12, 22, 32) is connected to the server (40) via the same source NAT router (14, 24, 34); the server (40) compares a public network address of the smart home device (10, 20, 30) with a public network address of the mobile terminal (12, 22, 32); and where the public network addresses match, the server (40) forwards an identification feature of the smart home device (10, 20, 30) to the mobile terminal (12, 22, 32).

The invention also provides a corresponding server, a corresponding computer program and a corresponding storage medium.

A method for forwarding a packet in a network. The network includes a first network node, a second network node, and a third network node. The method is applied to the first network node, and the method includes: generating a correspondence between a first segment identifier (SID) and a second SID, where the first SID is an identifier that corresponds to the private network, and the second SID is an SID of the third network node; receiving a first packet whose destination address is the first SID; and when it is determined that the second network node is unreachable, pushing the second SID into the first packet to generate a packet, and sending the packet to the third network node.

A method for routing a packet in a segment routing network includes extracting a destination Internet Protocol (IP) address from an IP header of the packet received by a routing node wherein the destination IP address includes a network identifier, a node identifier, a function identifier, and an argument; determining whether the network identifier and the node identifier match a routing node identifier; when the network identifier and the node identifier match the routing node identifier, determining a function to be executed based on the function identifier and the argument; when the function to be executed is determined, updating the node identifier, the function identifier, and the argument according to a segment list included in a segment routing header of the packet; and routing the packet according to the updated node identifier, the updated function identifier, and the updated argument in the destination IP address.

A routing system can provide a Dynamic-Hybrid Forwarding Information Base (DHFIB). A control component of the routing system can build a routing table that includes routing information (e.g., prefixes, addresses, etc.) for use by a first routing component. The routing table can be ordered or ranked based on traffic information from the first routing component. Then, the control component can create the DHFIB from the routing table, wherein the DHFIB is a portion of the routing table and related to the first routing component. As such, the portion of the routing table selected for the DHFIB can be the set of prefixes in the routing table that represent the most frequently routed or most important prefixes in the routing table. Finally, the control component can forward the DHFIB to the first routing component to allow the routing component to route communications.

Disclosed is an IPv6 network node managing method, comprising: a packet collecting step, a packet analyzing step, and an IPv6 address assigning step, for assigning a network node management IPv6 address with a visually recognizable suffix address code to a target network node which requests an IPv6 address assignment of DHCPv6, thereby improving IPv6 address recognition of the target network node and facilitating management of the network nodes.

An electronic device includes an address generator module that generates a source address for each traffic class to be sent using a network interface. The source address includes a Unique Local Address (ULA) prefix and an interface identifier having a traffic class identifier as one or more most significant bits and a randomly generated remainder. The address generator module generates a destination address having the ULA prefix and the traffic class identifier. When a processor of the electronic device is selecting a source address for the traffic class according to rules of a network layer protocol (e.g., IPv6), including a rule that a longest matching address of possible source addresses to the given destination is selected as the source address, the generated source address is selected due to the one or more most significant bits of the interface identifier matching with the traffic class identifier of the destination address.
