A system and method of defining the topology of a network-on-chip. The IP sockets and their data transfer connectivity are defined. The location of each IP socket is defined. A number of switches are defined so that there is at least one switch within a distance from each IP socket, the distance being less than that over which a signal propagates within one clock cycle period. The switches are coupled by links. Links may comprise pipeline stages, storage buffers, and are characterized by a data width.

Methods and apparatus of delegating instructions or data from a CU to an NOC node in a network on chip (NOC) is disclosed. The NOC node executes the delegated instructions or processes the delegated data. An NOC controller (NCC), which is operatively coupled to the CU and the NOC node, facilitates delegating the instructions or data from the CU to the NOC node.

A software-defined network (SDN) system, device and method comprise one or more input ports, a programmable parser, a plurality of programmable lookup and decision engines (LDEs), programmable lookup memories, programmable counters, a programmable rewrite block and one or more output ports. The programmability of the parser, LDEs, lookup memories, counters and rewrite block enable a user to customize each microchip within the system to particular packet environments, data analysis needs, packet processing functions, and other functions as desired. Further, the same microchip is able to be reprogrammed for other purposes and/or optimizations dynamically.

A router of a network-on-chip receives delay information associated with a plurality of links of the network-on-chip. The router determines at least one link of a data path based on the delay information.

An optical network-on-chip, an optical router, and a signal transmission method. The optical network-on-chip includes: N2 intellectual property IP cores, N2/2 gateways, and N2 optical routers. The N2 optical routers form two subnets, and every N2/2 optical routers form one subnet. Each gateway in the N2/2 gateways is connected to every two IP cores in the N2 IP cores, where IP cores connected to different gateways are different, and the two IP cores connected to each gateway are in one-to-one correspondences with the two subnets. The N2/2 gateways are in one-to-one correspondences with the N2/2 optical routers in each subnet in the two subnets, where each gateway is connected to an optical router that is in each subnet and that is corresponding to each gateway.

Embodiments provide a method for service deployment in a virtualized network and a server. The method includes: receiving, by a server, a service deployment request, where the service deployment request includes description of a to-be-deployed service, for example, node information, connection information, and information about access to a deployed service; creating, by the server, an instance of the service, including: creating node instances, and establishing a connection between node instances; and finally establishing, by the server, a connection between the to-be-deployed service and the deployed service according to the information about access to the deployed service.

Provided is an on-chip network device which basically operates in a packet switching network mode, establishes an exclusive communication path according to a request for a specific path, performs networking in a circuit switching network mode, and switches a network mode back to the packet switching network mode, when communication in the circuit switching network mode is terminated.

Various embodiments are described wherein a set of devices are configured to be a logical mesh network. Each device has a logical mesh network address. Further, the set of logical mesh network addresses form a sequence from a first address to a last address, and intermediate addresses having both a preceding and a next address. The devices store forwarding information used to determine how to forward a received logical mesh network packet. Other embodiments are described and claimed.

A method and device for interworking between a physical network and a virtual network is provided. The implementations may include creating a network connection container. The network connection container may include a first virtual LAN interface configured to connect to a physical network, a second virtual LAN interface configured to connect to a virtual network, and a virtual extensible LAN interface configured to connect the first virtual LAN interface and the second virtual LAN interface.
