A method for configuring a network device. The method includes writing a route for a destination IP prefix to the forwarding information base (FIB), and after writing the route, obtaining a set of routes and writing the set of routes to a routing information base (RIB). The method further includes, after writing the set of routes to the RIB and after the expiration of a timer: identifying, in the RIB, a set of ECMP routes from the plurality of routes for the destination IP prefix, processing the set of ECMP routes for the destination IP prefix, and updating the FIB of the network device based on set of processed ECMP routes.

Various systems and methods to facilitate general communication, via a memory network, between compute elements and external destinations, while at the same time facilitating low latency communication between compute elements and memory modules storing data sets, without impacting negatively the latency of the communication between the compute elements and the memory modules. General communication messages between compute nodes and a gateway compute node are facilitated with a first communication protocol adapted for low latency transmissions. Such general communication messages are then transmitted to external destinations with a second communication protocol that is adapted for the general communication network and which may or may not be low latency, but such that the low latency between the compute elements and the memory modules is not negatively impacted. The memory modules may be based on RAM or DRAM or another structure allowing low latency access by the compute elements.

In one embodiment, a traffic management system includes an input/output sub-system to receive route search requests from client devices, and a CPU to search a route database for a suitable match for the route search requests yielding routes. The input/output sub-system is operative to receive data related to traffic levels along the routes. The CPU is operative to calculate a score for each route, select N quickest routes, and allocate the N quickest routes among the client devices. A first and second client device are allocated a first and second quickest route from the N quickest routes, respectively, the first and second quickest route having a first and second score, respectively. The second score is different to the first score. The input/output sub-system is operative to send to each client device data about the route allocated to that client device. Related apparatus and methods are also described.

The present disclosure identifies topologies of a computer network where one network appliance may be configured as a master network appliance and where that master network appliance may communicate over a network communication interface with one or more slave network appliances. Computer networks of the present disclosure may include a switch and a firewall where the switch may be coupled to several network appliances via different network communication interfaces.

In one embodiment, a central device receives a routing strategy instruction that specifies a predictability threshold for communication delays in the network. The device estimates communication delays for a plurality of paths in the network and determines predictability measurements for the estimated delays. The device also selects, from among the plurality of paths, a particular path that has a predictability measurement that satisfies the predictability threshold and has a minimal estimated delay. The central device further installs the particular path at one or more other devices in the network.

Techniques for providing mobile device content delivery acceleration are discussed herein. Some embodiments may provide for a system including a mobile device and a mobile accelerator system. The mobile accelerator system may include point of presences (“POPs”) configured to facilitate accelerated content delivery to the mobile device from a content server. For example, the mobile device may be configured to: determine an entry POP from POPs of a mobile accelerator system; and create a dedicated transport channel with the entry POP. The entry POP of the mobile accelerator system may be configured to: receive a query to a content server from the mobile device via the dedicated transport channel; determine at least a portion a dynamic path between the mobile device and the content server; and route data transfers between the mobile device and the content server through the at least a portion of the dynamic path.

In a multiple interface, low power and lossy network comprising a plurality of nodes, a low transmission power and medium transmission power topology are defined for the network and a channel-hopping schedule is defined for the devices operating in each topology. A sender determines that data is capable of being transmitted via a link on the low transmission power topology. The sender determines the transmission parameters for the transmission of the data over the link on the low transmission power topology and determines a low transmission power channel for transmission of the data. The sender transmits the determined channel and the transmission parameters to the receiver. The sender transmits the data via the determined channel in the low transmission power topology.

A method for engineering traffic in a communications system includes determining a set of delay constraints associated with a traffic flow over the communications system, and excluding non-convex constraints from the set of delay constraints, thereby producing a set of convex constraints. The method also includes selecting a path solution for the traffic flow in accordance with the set of convex constraints, and sending information regarding the path solution to nodes in the communications system.

A method for determining a path in an optical network, implemented by one or more controllers associated with a control layer, includes receiving a path request specifying start and end points, an associated bandwidth, and a longevity parameter providing an anticipated length during which the path is required; determining a route in the optical network through a routing algorithm executed by the controller, wherein the routing algorithm utilizes the start and end points, the associated bandwidth, and the longevity parameter to determine the path; and provisioning the path through a plurality of switches along the route.
