  • Publication number: 20190104037
    Abstract: A data-driven approach to network performance diagnosis and root-cause analysis is presented.

  • Patent number: 10205634
    Abstract: An adaptive multi-phase approach to estimating network parameters is presented. By gathering and aggregating raw network traffic data and comparing against default network parameters, a training data set may be generated. A black box optimization may be used in tandem with a supervised learning algorithm to bias towards better choices and eventually pick network parameters which optimize performance. Data delivery strategies are applied to deliver content using the optimized network policies based on the estimated parameters.

  • Patent number: 10135683
    Abstract: In general, techniques are described for dynamically generating attributes from routing topology information and assigning dynamically generated attributes to network map entries to further characterize PIDs described therein. For example, a provider or other entity assigns, within a network device, endpoint types to one or more address prefixes for which the network device originates or forwards route advertisements. For each typed prefix, the network device adds an endpoint type identifier for the assigned endpoint type to route advertisements that traverse or originate with the network device and specify the prefix. An ALTO server peers with router advertisers to receive route advertisements. When the ALTO server receives a route advertisement that includes an endpoint type identifier, the ALTO server maps the endpoint type identifier to a PID attribute and assigns the PID attribute to a PID that includes a prefix identified in the route advertisement.

  • Publication number: 20180278571
    Abstract: Network performance data, such as routing trip time between autonomous systems and data centers, is gathered and aggregated to determine optimal mappings of autonomous systems and data centers. Autonomous system based DNS steering may be automated by repeating a life cycle of determining the optimal mappings. Data delivery strategies are applied to a portion of a network to deliver content using the optimal mappings.

  • Publication number: 20180278688
    Abstract: A CDN traffic is optimized by a client-side system that maps the servers in the CDN system. Content requests from client devices for domain names are forwarded to servers in the CDN system that may be selected from the map to prevent a cache miss in the a server for a particular request for content.

  • Patent number: 10084720
    Abstract: Using the ALTO Service, networking applications can request through the ALTO protocol information about the underlying network topology from the ISP or Content Provider. The ALTO Service provides information such as preferences of network resources with the goal of modifying network resource consumption patterns while maintaining or improving application performance. This document describes, in one example, an ALTO server that intersects network and cost maps for a first network with network and cost maps for a second network to generate a master cost map that includes one or more master cost entries that each represent a cost to traverse a network from an endpoint in the first network to an endpoint in the second network. Using the master cost map, a redirector may select a preferred node in the first network with which to service a content request received from a host in the second network.

  • Publication number: 20180159947
    Abstract: A system for improving network data communications performance between end-user devices and content origin servers. A plurality of accelerators are distributed across a network and communicate with end-user devices and content origin servers. Software development kits installed on end-user devices monitor control channel data traffic between the end-user devices and accelerators. Various data traffic efficiency approaches are implemented by the software development kits on the end-user devices and the plurality of accelerators resulting in improved data communications links between the end-user devices and the content origin servers.

  • Patent number: 9967185
    Abstract: An example network device includes a network interface and a control unit that receives a packet having header information. The control unit includes a forwarding structure having a plurality of entries that each refers to one of a plurality of logical interfaces, a forwarding engine configured to access the forwarding structure to select a first logical interface to which to forward the packet based on the header information, wherein the first logical interface comprises a pseudo-device interface (PDI). The control unit also includes a PDI module that tunnels the packet to an external service complex (ESC) by at least applying a set of metadata to the packet, encapsulating the packet with a header, and forwarding the packet to the ESC via the network interface, and wherein the metadata allows the ESC to determine a set of services to be applied to the packet based on the metadata.

  • Publication number: 20160352631
    Abstract: In general, techniques are described for using routing information obtained by operation of network routing protocols to dynamically generate network and cost maps for an application-layer traffic optimization (ALTO) service. For example, an ALTO server of an autonomous system (AS) receives routing information from routers of the AS by listening for routing protocol updates outputted by the routers and uses the received topology information to dynamically generate a network map of PIDs that reflects a current topology of the AS and/or of the broader network that includes the AS. Additionally, the ALTO server dynamically calculates inter-PID costs using received routing information that reflects current link metrics. The ALTO server then assembles the inter-PID costs into a cost map that the ALTO server may provide, along with the network map, to clients of the ALTO service.
