Abstract: A method of postponing an electronic message is performed at a computing device having one or more processors and memory. The memory stores one or more programs configured for execution by the one or more processors. The device displays a first electronic message for a user of the computing device and receives user input to postpone the first electronic message. In response to the user input, the device displays a plurality of postponement locations in a user interface window and receives user selection of a postponement location from the displayed plurality of postponement locations. The device then inhibits display of the first electronic message at the computing device. When it is subsequently determined that the computing device is at the first postponement location, the device redisplays the first electronic message.

Abstract: Techniques are described for providing a method and apparatus for determining source address validation of a data packet in a network in the presence of asymmetric routing.

Abstract: Novel tools and techniques are provided for implementing name-based routing through networks. In various embodiments, a broker manager in each of a plurality of networks may receive a subscription request for a network device from a client device, each device being locally accessible or disposed in an upstream or downstream network. The broker manager uses its client broker to communicate with a locally accessible client device, and uses its mediator broker (and, sometimes, an intermediate device(s)) to communicate with a locally accessible network device. The broker manager otherwise uses its messaging brokers to communicate with control channels of one or more networks. Once subscription with the network device has been established, any commands and responses between the client device and the network device may be routed over pub/sub channels via the broker managers and their brokers using name-based routing, without routing based on IP address of the network device.

Abstract: Manifest files for proxies within an application mesh or service mesh are created using parallel computing. Virtual services in a mesh definition are identified. For each of the virtual services, one or more virtual nodes that receive traffic from the virtual service are identified. For each of the virtual nodes that receive traffic from the virtual service, an edge is added to a first graph. Virtual nodes that send network traffic to at least one of the virtual services are then identified. For each virtual node that sends traffic to the virtual service, an edge is added to a second graph. Then an optimized per node network topology is generated based at least in part on the first graph and the second graph.

According to the method, the first node receives first traffic, where the first node is a source node that sends the first traffic on the ring link; and the first node sends the first traffic to the third node, where two reachable paths with equal hop counts are included from the first node to the third node, the first node sends the first traffic to the third node on a preset first transmission path, the first transmission path passes through the second node, and the first transmission path is one of the two reachable paths with equal hop counts. This method can reduce computing load of nodes while implementing non-blocking switching of traffic between the nodes.
