Abstract: Methods, systems, and devices are disclosed to facilitate operation of a network. First network state data descriptive of a first network state is received. The first network data includes network demand associated with nodes of a dynamic network, where the nodes of the dynamic network include at least one movable node. The first network data also includes a node state of each node of the dynamic network. At least one first link is automatically established between two or more nodes of the dynamic network to satisfy at least a portion of the network demand. Link data is generated where the link data is descriptive of node utilization, the at least one first link, and assignment of the portion of the network demand to the at least one first link. One or more changes to the dynamic network are modeled based on the link data to identify a second network state, wherein the second network state satisfies a greater quantity of the network demand than the first network state.

Abstract: A method is described for routing data from a first node to a second node via a gateway. The second node is detected at the gateway, which determines a local identifier of the second node. A name and a global address are associated with the second node. The name and the global address are published to a name service, such that the first node can retrieve the global address based on the name. The gateway receives data from the first node that is addressed to the global address and transmits the data to the second node using the local identifier. The gateway includes software implementing a service-oriented architecture (SOA). Any number of additional services may be added to process messages passing through the gateway.

Abstract: According to an embodiment, a method includes a Delay Tolerant Network (DTN) software overlay residing in a first plane of a node of the network is used to define hierarchical forwarding behavior for data being generated in the first plane. In a second plane of the network, local buffering and data retransmission is performed in response to at least one intermittent network outage. Communication between the first and second planes is performed to manage the transmission of data between the first and second planes as needed in the event of at network outage that is longer in duration than the at least one intermittent network outage, to thus prevent the loss of data.

Abstract: Techniques for communicating data through a network so as to satisfy various Quality Of Service (“QOS”) levels are described. The QOS levels may be selected based on a determined type of the data or the data communication, such as by a network manager after the data communication is registered, and QOS communication parameters are selected for the data communication to ensure that the QOS levels are achieved. Other techniques may also be used to ensure that a selected QOS level is achieved, including selecting an appropriate path through the network, controlling other data communications that use some or all of the selected path, and/or enabling preemption of such other data communications. QOS levels that are actually achieved may also be monitored, and the QOS communication parameters and/or path for a data communication may be dynamically modified based on differences between actual achieved QOS levels and desired QOS levels.

Abstract: An interconnect fabric module (“IFM”) with high-speed switching capabilities. An interconnect fabric module can be dynamically configured to interconnect its communications ports so that data can be transmitted through the interconnected ports. Multiple interconnect fabric modules can be connected to form an interconnect fabric through which nodes (e.g., computer systems) can be interconnected. In one embodiment, data is transmitted through the interconnect fabric as frames such as those defined by the Fibre Channel and InfiniBand standards. The interconnect fabric module allows the creation of an interconnect fabric that is especially well suited for interconnecting devices utilizing multiple information types such as might be required by the devices of an enterprise data network (“EDN”).

Abstract: A method and system for managing an interconnect fabric that connects nodes. A network manager manages an interconnect fabric or network of routing devices (e.g., interconnect fabric modules, switches, or routers) to allow source nodes to transmit data to destination nodes. The network manager receives registration requests from source nodes to send data to destination nodes, configures the routing devices of the network to establish a path from each source node to its destination node, and provides a virtual address to each source node. The virtual address identifies a path from the source node to the destination node. The source node sends the data to its destination node by providing the data along with the virtual address to a routing device of the network.

Abstract: A method, system, and computer-readable medium for integrating multiple techniques for processing data communications is described in which the processing steps shared by multiple of the techniques do not have to be duplicated by each of the techniques. In some situations, some or all of the multiple processing techniques are performed in parallel, such as on different processors. In some situations, a Multi-Protocol Edge Switch (“MPEX”) is used to integrate multiple processing techniques for received data communications that are to be forwarded to a destination, such as by performing protocol translation, performing load balancing between multiple alternative destinations on one or more of the networks to which the MPEX belongs, performing firewall and other content-based analysis for any or all of the nodes on one or more of the networks to which the MPEX belongs, and/or providing content-based routing of data communications in order to identify appropriate destinations.

Abstract: A method, system, and computer-readable medium for using virtual identifiers to route communications through a network to destinations in an appropriate manner is described. The virtual identifiers can each be assigned to one or more paths through a network to a destination, such as by a network manager for the network. An appropriate virtual identifier for routing a data communication can also be identified in various ways, such as by registering the data communication with a network manager for the network and receiving an appropriate virtual identifier in response. A virtual identifier identified for a data communication may also be assigned to a path to one or more destinations that are selected as being appropriate in various ways, including selecting destinations that do not include a destination specified by a source of the communication.

Abstract: A method, system, and computer-readable medium for processing received data communications that are routed through a network by using virtual identifiers is described. The virtual identifiers can each be assigned to one or more paths through a network to a destination, such as by a network manager for the network. When a destination receives a communication routed using a virtual identifier, the received communication can be processed based on the virtual identifier. In some situations, a received data communication is forwarded to one or more resources of the destination that are associated with the virtual identifier used to route the communication, such as an executing application program. In addition, the received data communication can be modified before the forwarding, such as to add network address information that is expected by the resource by, for example, retrieving information that is associated with the virtual identifier used to route the communication.
