Abstract: In various examples, an extensible network traffic engineering platform monitors network traffic and application performance to dynamically update network ingress and egress communication paths for increasing performance of the application—such as a cloud gaming application, a cloud virtual reality (VR) application, and/or another high performance application types. Pluggable, distributed, application-centric network monitors, policy engines, and network configurators are implemented at the edge to detect degraded network and application performance and dynamically update network routing to account for the same.

Abstract: A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a route through the limited portion of the network to the target node is determined, other nodes are configured (e.g. via source routing) to cause the packet to traverse the determined route, and the packet is forwarded toward the target node.

Abstract: Some embodiments provide a method for configuring an edge computing device to implement a logical router belonging to a logical network. The method configures a datapath executing on the edge computing device to use a first routing table associated with the logical router for processing data messages routed to the logical router. The method configures a routing protocol application executing on the edge computing device to (i) use the first routing table for exchanging routes with a network external to the logical network and (ii) use a second routing table for exchanging routes with other edge computing devices that implement the logical router.

Abstract: A packet network includes a plurality of network elements interconnected to one another via a plurality of links, and systems and methods include, responsive to detecting a signal degrade condition on a link in the packet network, advertising the signal degrade condition on the link; maintaining a Traffic Engineering database which includes signal degrade condition status based on the advertising; and, responsive to path computation through the packet network, determining a best path considering the signal degrade condition status of the plurality of links. The systems and methods include further include, responsive to detecting the signal degrade condition on the link has cleared, advertising the signal degrade condition has cleared on the link.

Abstract: Responsive to receiving the BGP UPDATE message, a route reflector may (1) update a CLUSTER_LIST value and, if needed, an ORIGINATOR_ID value, in a path attribute section in the BGP UPDATE message to generate a revised BGP UPDATE message, and (2) send the revised BGP UPDATE message to a client of the route reflector, regardless of whether or not one of (A) field validity checking of the BGP UPDATE message, (B) Adj-RIBS-In update using the BGP UPDATE message, (C) decision processing for route selection using information in the BGP UPDATE message, or (D) Adj-RIBS-Out update using the BGP UPDATE message, is completed (or perhaps even started). This provides faster route propagation and avoids delays associated with processing BGP UPDATE messages (NLRI with advertisements and withdrawals) at each hop the NLRIs using conventional BGP such as next-hop validation, best path selection, etc.

Abstract: A computer executes a first determination procedure determining a first link which at least partially overlaps a disaster area representing a range reached by an influence of a predetermined disaster, among links constituting a network, a second determination procedure determining a second link which at least partially overlaps a road area representing a range of a road width of a predetermined road used to recover from the disaster, among the links constituting the network, a route search procedure searching for a plurality of routes from a start point node to an end point node constituting the network, a grouping procedure grouping the plurality of routes searched for by the route search procedure into groups depending on a first parameter value that is based on the first link included in the routes, a computing procedure computing, for each of the plurality of routes searched for by the route search procedure, a second parameter value that is based on the first link and the second link included in the routes, and a selecting procedure selecting a predetermined number of routes among one or more routes grouped into the same group on the basis of the second parameter value computed by the computing procedure for each of the groups grouped by the grouping procedure.

Abstract: A method and device for operating a network component and a control instance in a software-defined networking communication infrastructure. The software-defined networking communication infrastructure is switched from an operation according to a first strategy for forwarding time-critical data streams in network components of the communication infrastructure to an operation according to a second strategy for forwarding time-critical data streams in network components as a function of at least one trigger signal, the at least one trigger signal being received in an operation according to the first strategy from a control instance in a unicast message or in a broadcast message.

Abstract: Gateway devices at different sites of a primary Anycast network provide access to the sites by advertising a first set of Anycast addresses. A secondary shadow Anycast network advertises different second sets of Anycast addresses from the different sites in order to predetermine traffic shifts that occur as a result of changing one or more of the second set of Anycast addresses that are advertised from one or more of the sites. A traffic shifting device may implement a predetermined traffic shift in the primary Anycast network by selecting a particular second set of network addresses that produces a traffic shift at least equal to the predetermined traffic shift, mapping the particular second set of network addresses to a modified first set of addresses, and modifying routing in the primary Anycast network by advertising the modified first set of addresses instead of the first set of addresses.

Abstract: A congestion notification method, a related device, and a system, where the method includes receiving, by a network side device, a congestion status of a target network area sent by a radio access network (RAN) congestion awareness function (RCAF) entity, where the target network area is a network area involved in an application service provided by a target application server; and sending, by the network side device, the congestion status of the target network area to the target application server. Hence, an application server may able to learn in time when congestion occurs, and adjust, according to the congestion situation, a related service in an area corresponding to the congestion situation.
