In general, techniques are described for enabling a network of network devices (or nodes) to provide redundant multicast streams from redundant multicast sources to an egress network node. In some examples, the egress network node (or a controller for the network) computes maximally redundant trees (MRTs) from the egress network node to a virtual proxy node virtually added to the network topology by the egress network node for redundant multicast sources of redundant multicast streams.

A method is provided for consistent data processing by first and second distributed processing systems having different data partitioning and routing mechanisms such that the first system is without states and the second system is with states. The method includes dividing data in each system into a same number of partitions based on a same key and a same hash function. The method includes mapping partitions between the systems in a one-to-one mapping. The mapping step includes calculating a partition ID based on the hash function and a total number of partitions, and dynamically mapping a partition in the first system to a partition in the second system, responsive to the partition in the first system being unmapped to the partition in the second system.

An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables an endpoint to transfer data directly to another endpoint.

The present invention is related to a method for routing requests among a plurality of database servers. A device intermediary to a client and a plurality of database servers receives a request to access a database provided by the plurality of database servers. The plurality of database servers can include a first database server configured to process write requests and one or more second database servers configured to process read requests. The device determines that the request to access the database is a read request. The device identifies, responsive to determining that the request is a read request, one of the one or more second database servers to send the request instead of the first database server. The device then transmits the request to the identified second database server.

An example method of generating a configuration for a network on chip (NoC) in a programmable device includes: receiving traffic flow requirements for a plurality of traffic flows; assigning routes through the NoC for each traffic flow based on the traffic flow requirements; determining arbitration settings for the traffic flows along the assigned routes; generating programming data for the NoC; and loading the programming data to the programmable device to configure the NoC.

A system of specifying link layer information in a URL is described. In an embodiment, a URL is generated which includes both a link layer network type and information which is used by a resolving device to identify a particular link layer network of the specified type. In various embodiments, the URL includes a link layer network type and a corresponding link layer network name or pairs of link layer network types and corresponding link layer network names. Where the URL comprises more than one link layer network name, the resolving device may determine at runtime which of the named link layer networks to connect to and this decision may be based on criteria or preference information included within the URL.

The present application relates to methods and systems for intelligently routing requests to one of a plurality of redundant servers. The methods and systems route the requests to a most highly ranked redundant server. The redundant servers are dynamically rank according to ranking information, wherein the ranking information may include server performance information, server response information, next step performance information, next step response information, historic information and other like information. Next step response information and next step performance information corresponds to information pertaining to servers the plurality of redundant servers depend upon. The methods and systems may further randomly re-rank the plurality of redundant servers. The methods and systems may further re-route unprocessed requests meeting non-performance criteria.

Methods for transmitting and receiving data of a station includes setting a direct route to a corresponding station and a relay route to a relay device, selecting one route as between the direct route and relay route, and transmitting and receiving data through the selected route. A non-transitory computer-readable storage medium may store a program including instructions to cause a computer to perform the method. The setting may be performed by a processor and the transmitting and receiving may be performed respectively by a transmitter and a receiver.

A method including formatting an advertisement message having a dedicated preferred route to one of a first physical entity and a first logical entity of a first autonomous system (AS), the dedicated preferred route being based on at least two routing attributes, and transmitting the advertisement message from the first AS to a second AS. A routing device including a formatting module formatting an advertisement message having a dedicated preferred route to one of a first physical entity and a first logical entity of a first autonomous system (AS), the dedicated preferred route being based on at least two routing attributes, and a transmitting module transmitting the advertisement message from the first AS to a second AS.

Embodiments are directed to a sender side of a network communication, being sent from a sender to a destination over a network path, expressing certain conditions and actions in a form of a script and encoding the script into network packets, thus enabling routing decisions to be made. Routing devices along the network path are equipped with an execution environment and an application program interface (API) to allow the script to execute and intervene (i.e., talk with the routing device) in the routing process. Embodiments provided herein may be implemented to coexist with other existing routing protocols or may completely replace other existing routing protocols.
