A gateway provides duplex-directional, multimedia ad hoc mesh networking, peer-to-peer direct communications, power optimization, dynamic configuration, and data management, while operating within various devices and network topologies. A multitasking virtual machine monitor for mobile networked devices, that is capable of functional expandability and portability to various operating environments, interoperability with a variety of operating systems, the Gateway Control System (GCS) performs functional capabilities in both a local and a networked topology using local and remote hardware and software. Software within the GCS is partitioned into sequentially, autonomous code, referred to herein as “modules,” each module being configured to communicate with hardware and other gateway modules. Collectively, all gateway modules are referred to herein as the gateway stack (GS). Each member of the GS can be turned on or off, downloaded from a remote site, and dynamically configured.

A method and system for transmitting and receiving data packets between two network nodes via one or more end-to-end connections. An interface is provided for selecting one or more possible end-to-end connection(s) or established end-to-end connection(s). The method and system may further comprise receiving a policy, wherein one or more selected end-to-end connections are established based, at least in part, on the policy. The policy may also restrict or promote selection of certain established end-to-end connection(s) via the interface provided. The selected and established end-to-end connection(s) are used for transmitting and receiving data packets.

The present invention relates to a traffic distribution method, apparatus, and system. The method includes: receiving a current packet sent by a first entity; acquiring layer 7 application information according to the current packet; if the layer 7 application information is acquired, matching the current packet with a layer 7 traffic distribution policy according to the layer 7 application information; and sending the current packet to a service server after the current packet matches the layer 7 traffic distribution policy. In this way, the present invention implements traffic distribution based on the layer 7 application information, enhances performance of a traffic distribution device, and reduces deployment costs of an operator.

In the field of network communications, a protection method for a multi-domain network includes: after a second node detects that a first link fails, disconnecting a first protection path on the node, connecting a first sub-path and a path that is within a second domain, uses the second node as an endpoint, and is used to bear a service; sending, on the first sub-path, a first failure monitoring message that carries first maintenance information to a third node, where the first maintenance information is the same as second maintenance information carried in a second failure monitoring message; the second failure monitoring message is a message that is sent on the first protection path by a first node to the third node and is used to monitor a failure of the first protection path.

The present invention discloses a data switching apparatus and system, where the data switching apparatus includes: an optical-to-electrical conversion unit, an identification unit, an electrical switching unit, an electrical-to-optical conversion unit, an optical switching control unit, and an optical switching unit. The optical-to-electrical conversion unit is configured to perform optical-to-electrical conversion on a first optical data packet and an optical label, where the optical label carries switching information of a second optical data packet, and the first optical data packet and the second optical data packet are respectively to-be-switched data packets that need to use electrical packet switching and optical packet switching. The identification unit is configured to identify whether an electrical signal output by the optical-to-electrical conversion unit is from the optical label or the first optical data packet.

Arrangements and methods for improving data communication in a network are disclosed. The method includes receiving data packets and segregating the data packets into at least original packets and replicated packets. The method also includes prioritizing original packets having service level agreement (SLA) requirements, the prioritizing is performed with respect to at least one of queuing and de-queuing such that SL parameters for the original packets met.

Each compute node of a cluster compute server generates and maintains route information for routing messages to other nodes of the server. Each compute node identifies the other nodes connected to a fabric interconnect and generates, based on a set of routing constraints, routes to each of the other nodes. Each compute node communicates messages to other nodes of the server via the generated routes. Because the routes are generated at each compute node the processing load to generate the routes is distributed among the compute nodes.

In one example, a plurality of network devices forming an Internet protocol (IP) fabric includes first, second, third, and fourth network devices. The first network device includes a plurality of network interfaces communicatively coupled to at least the third and fourth network devices of the plurality of network devices, which are between the first network device and the second network device. The first network device also includes one or more hardware-based processors configured to determine available bandwidths for the third network device and the fourth network device toward the second network device, determine a ratio between the available bandwidths for the third and fourth network devices, and forward data (e.g., packets or bytes) toward the second network device such that a ratio between amounts of the data forwarded to the third and fourth network devices corresponds to the ratio between the available bandwidths.
