TLDR
In this article, a domain name server includes a processor configured to receive a request from a requester for an edge cache address, identify a first edge cache serving content requests to an anycast address from the requester, and determine a load of first-edge cache.
Abstract: 
A domain name server includes a processor configured to receive a request from a requester for an edge cache address, identify a first edge cache serving content requests to an anycast address from the requester, and determine a load of first edge cache. The processor is further configured to provide unicast address of an alternate edge cache to requester in response to the request when the load exceeds a threshold or to provide anycast address to requester in response to request when the load is below the threshold.

Method and apparatus for coupling an antenna to a device

Paul Shala Henry, +5 more
TL;DR: In this paper, the authors describe a system that receives, by a feed point of a dielectric antenna, electromagnetic waves from a core coupled to the feed point without an electrical return path, and radiates a wireless signal responsive to the electromagnetic waves being received at the aperture.

Backhaul link for distributed antenna system

Paul Shala Henry, +5 more
TL;DR: In this paper, a distributed antenna and backhaul system provide network connectivity for a small cell deployment using high-bandwidth, millimeter-wave communications and existing power line infrastructure, rather than building new structures, and installing additional fiber and cable.
Patent

Remote distributed antenna system

Farhad Barzegar, +5 more
TL;DR: In this article, a distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas.
Patent

Method and apparatus for sensing a condition in a transmission medium of electromagnetic waves

Mitchell Harvey Fuchs, +1 more
TL;DR: In this article, the authors describe a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire.
Patent

Method and apparatus that provides fault tolerance in a communication network

Paul Shala Henry, +5 more
TL;DR: In this article, a system for detecting a fault in a first wire of a power grid that affects a transmission or reception of electromagnetic waves that transport data and that propagate along a surface of the first wire is described.

Content distribution system for operation over an internetwork including content peering arrangements

Steven Mccanne
TL;DR: In this article, the content providers are coupled to at least one content distribution network of a plurality of content distribution networks and a request for the content is sent from the client to a redirector node that receives requests.
Patent

Proximity-based redirection system for robust and scalable service-node location in an internetwork

Steven Mccanne, +1 more
TL;DR: In this paper, a proximity-oriented redirection system for service-to-client attachment in a virtual overlay distribution network is proposed, where a packet of data is routed from a source node to a destination node based on address fields of the packet.
Patent

System and method for using network layer uniform resource locator routing to locate the closest server carrying specific content

J.J. Garcia-Luna-Aceves, +1 more
TL;DR: In this paper, a request for an information object at an address identified by a uniform resource locator (URL) is received; and the URL is mapped to a corresponding anycast address for the information object.
Patent

Server load balancing using IP option field approach to identify route to selected server

Sunil K. Srivastava
TL;DR: In this paper, the first packet of a server reply to a request from the client is stored in a send path list for server load balancing, and the subsequent packets are forwarded to the same server without hop-by-hop routing decisions or repeated load balancing decisions.
Patent

Geospacial internet protocol addressing

Dan A. Preston, +1 more
TL;DR: GeoIP as discussed by the authors is an addressing scheme that supports current TCP/IP (v4) and future addressing (v6/ng) requirements and allows a decentralization of the unicast point to device on the hosted network.
