A system for efficient routing of an (OAM) frame in an Ethernet switch receives an OAM frame at a first port; building a first classification key dependent on an OAM frame header; classifies in a context of the first port to create a first classification; resolves action dependent on the first classification; modifies the first classification key to create a second classification key; classifies the frame in a context of the second port to create a second classification; sends the second classification key to an OAM engine coupled to the Ethernet switch for modification into a third classification key; receives the third classification key from the OAM engine; modifies the third classification key into a final classification key; modifies the header of the OAM frame with the final classification key; and sends the modified OAM frame to a switching fabric of the Ethernet switch.

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

Broadband communications devices and methods operate with at least two separate communication paths between the devices and the network, such as the Internet. The broadband devices and methods receive data concurrently over the communication paths or separately. The bandwidth is increased when the separate communication paths are combined. The broadband devices employ packetized data with Voice over Internet Protocol (VoIP) technologies combined with RF communications technologies.

A system, a method, and a computer program for generating a dynamically configurable resolution route for transmitting a request object to one or more nodes in a network, comprising receiving a trigger signal from a first node, determining one or more destination nodes based on a resolution process, schema or scenario, determining a pathway to the one or more destination nodes, generating a resolution route for transmitting the request object in the network, iteratively transmitting the request object to the one or more destination nodes based on the resolution route, receiving a request object resolution signal from a final destination node, and transmitting the request object resolution signal to the first node based on the request object resolution signal.

Cloud based router with policy enforcement. In some implementations, a system is provided. The system includes a plurality of access points. The plurality of access points receive data packets from a plurality of client devices. The system also includes a plurality of tunnel devices coupled to the plurality of access points. The plurality of tunnel devices generate encapsulated packets based on the data packets received by the plurality of access points. The system further includes a plurality of packet forwarding components coupled to the plurality of tunnel devices via a first set of tunnels. The plurality of packet forwarding components receive the encapsulated packets from the plurality of tunnel devices and forward the encapsulate packets. The system further includes a plurality of network access controllers coupled to the plurality of packet forwarding components via a second set of tunnels. The plurality of network access controllers enforce one or more network policies for the plurality of client devices, as the plurality of client devices move between the plurality of access points.

A system, method and program product for electronic communication includes checking and determining if a current called number of a subscriber is on a list of recent calls made by an onward caller where either the onward caller or the receiving caller enter a certain combination of symbols using the onward calling device or the receiving device respectively when the call is in progress. Calling route used to establish a connection between the onward caller and the subscriber is concluded as a low-quality route. Subscriber ID is extracted and included on the list of low quality routes. Request is made for a list of all possible routes for communication between the onward caller and receiver user. A comparison of the list of all possible routes and low quality routes is made. A route not earlier marked as a low-quality route is identified and selected. An electronic communication between the onward caller and receiving user is established using the selected route.

Disclosed herein are systems and methods for multi-level classification of data traffic flows based on information in a first packet for a data traffic flow. In exemplary embodiments of the present disclosure, a key can be generated from intercepted DNS data to track data traffic flows by application names and destination IP addresses. Based on these keys, patterns can be discerned to infer data traffic information based on only the information in a first packet, such as destination IP address. The determined patterns can be used to predict classifications of future traffic flows with similar key information. In this way, data traffic flows can be classified and steered in a network based on limited information available in a first packet.

A method and device for processing routing table entries are provided. The method includes: determining a first portion and a second portion in a network portion of an ipv6 address and a first virtual route forwarding instance identifier corresponding to the ipv6 address, the first portion being high 32 bits of the network portion and the second portion being low 32 bits of the network portion; combining the first portion and the first virtual route forwarding instance identifier to obtain first combined information, determining a first prefix index corresponding to the first combined information, and combining the second portion and the first prefix index to obtain second combined information; and correspondingly storing the first combined information and the first prefix index in a first routing table as routing table entry in the first routing table, and storing the second combined information in a second routing table as routing table entry in the second routing table. The problem of waste of storage resources for ipv6 route storage in the related art is solved.

To improve the efficiency and reliability of communication, such as for control commands distribution and data collection, in a large and high density wireless control system (100), each one of a plurality of nodes in the system is assigned one out of three roles, a router node (200), a non-router node (300), or a data collector node (400). A node (200, 300, 400) in the wireless control system (100) is capable to operate according to at least one of two communication protocols. A first communication protocol is capable to support mesh or tree network with multi-hop routing, while a second communication protocol is capable to support a star network with point-to-point connection. The router nodes build up a sparse multi-hop network to guarantee the connectivity of the large-scale network. Around each router node within one-hop direct link, a local star network is built up with at least one non-router node and at least one data collector node.
