The method includes, at each internal interconnection device among multiple interconnection devices of each processing subsystem: in response to receiving a multicast access request to a destination memory, determining a shortest path from each internal interconnection device to the destination memory based on a topology structure of the mesh network system; where the internal interconnection device has no link connected to an external processing subsystem; in response to determining that the number of the shortest path is equal to one, routing the multicast access request to the destination memory along the shortest path; in response to determining that the number of the shortest path is greater than one, determining a next-hop interconnection device for the multicast access request based on a second static routing policy.

A network device receives an attribute identifying paths associated with an open shortest path first (OSPF) domain of a network and an intermediate system to intermediate system (ISIS) domain of the network, and provides the attribute to other network devices of the network. The network device receives traffic destined for one of the other network devices of the network, and determines that a primary path is unavailable for routing the traffic to the one of the other network devices. The network device selects a secondary path from the paths identified by the attribute. The secondary path is selected based on determining that the primary path is unavailable, and the secondary path is associated with the OSPF domain or the ISIS domain of the network. The network device provides the traffic to the one of the other network devices via the secondary path.

Systems and methods include receiving network topology information of a network including a plurality of routers; receiving link measurements defining bandwidth on links in the network; determining routes in the network based on the network topology information; and utilizing the routes and the link measurements to determine an estimate of an initial traffic matrix that includes the bandwidth between origin routers and destination routers.

The method of some embodiments selects a set of links to forward packets of a data flow from an application running on a machine connected to an SD-WAN that has multiple exits. The method, based on computed sets of attributes for a first set of links and a second set of links, selects between the first set of links and the second set of links. At least the first set of links has multiple links and at least one attribute of the first set of links is an attribute that is computed by aggregating an attribute of each of the links in the first set of links. The method uses the selected set of links to forward the packets of the data flow of the application to an egress managed forwarding element of the SD-WAN.

A method of communication between nodes in a telecommunications network. Each node maintains a copy of a shared digital ledger, is identified by a respective identification code and implements a software application configured to manage the transmission of data packets and maintain the shared digital ledger. The method includes: memorizing a list of identification codes, each code identifying a respective node included in a subset of nodes of the network, identifying a receiver node to transmit the data packet, generating a data packet to be delivered to a recipient node, transmitting to the first node of the minimum sequence of nodes the data packet, issuing a request to the network nodes to record the data packet transmission in the distributed ledger, and when a data packet is received, the method requires that each receiver node, other than the recipient node of the data packet, repeats at least some steps.

A traffic shifting system is described to shift traffic away from one or more network devices or interfaces. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter associated with an interface on any devices for which traffic is being shifted. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

Embodiments of the present disclosure provide a content based routing method and apparatus. The method may include: judging, in response to receiving a service request, whether the service request matches a preset shunt rule, the preset shunt rule including a request content and a request context; and forwarding, in response to judging that the service request matches the preset shunt rule, the service request to a service cluster corresponding to the preset shunt rule matching the preset service request.

A highly predicable quality shared distributed memory process is achieved using less than predicable public and private internet protocol networks as the means for communications within the processing interconnect. An adaptive private network (APN) service provides the ability for the distributed memory process to communicate data via an APN conduit service, to use high throughput paths by bandwidth allocation to higher quality paths avoiding lower quality paths, to deliver reliability via fast retransmissions on single packet loss detection, to deliver reliability and timely communication through redundancy transmissions via duplicate transmissions on high a best path and on a most independent path from the best path, to lower latency via high resolution clock synchronized path monitoring and high latency path avoidance, to monitor packet loss and provide loss prone path avoidance, and to avoid congestion by use of high resolution clock synchronized enabled congestion monitoring and avoidance.
