Patent number: 9515980Abstract: A method or system for transferring information during the domain name service (DNS) lookup to more effectively utilizing the content delivery network (CDN) is disclosed. Information gathered from DNS request is used to identify information on how to serve the content with a chosen IP address returned from the DNS lookup. The DNS server selects from a number of possible IP addresses after analyzing information from the DNS request and popularity of associated content. The different IP addresses will result in different edge servers providing content. An IP address could be provided for popular content in a way that will tend to populate more content caches from the pool of edge servers in one embodiment.Type: GrantFiled: February 3, 2014Date of Patent: December 6, 2016Assignee: Limelight Networks, Inc.Inventors: Jason Eggleston, Nils H. McCarthy, Bradley B. Harvell, Mohan I. Kokal, Lee A. Stafford, Gary S. Baldus, Michael M. Gordon, Nathan F. Raciborski

Aluminum/alkyline or alkali/titanium containing polyesters having improved reheat, color and clarity
Patent number: 8791187Abstract: A polyester composition containing: a) aluminum atoms; and b) alkaline earth atoms or alkali metal atoms or alkali compound residues such as lithium atoms; and c) particles comprising titanium, zirconium, vanadium, niobium, hafnium, tantalum, chromium, tungsten, molybdenum, iron, or nickel atoms or combinations thereof, where the particles improve the reheat rate of the polyester composition. The polyester polymer compositions may also contain phosphorus catalyst deactivators/stabilizers. The polyester compositions and the articles made from the compositions such as bottle preforms and stretch blow molded bottles have improved reheat rate while maintaining low haze, high L*, a b* below 3, and have low levels of acetaldehyde. In the process for making the polyester polymer, the polymer melt is polycondensed in the presence of a) and b), with the particles c) added in a melt phase process or added to the polymer in an injection molding machine or extruder.Type: GrantFiled: May 31, 2011Date of Patent: July 29, 2014Assignee: Grupo Petrotemex, S.A. de C.V.Inventors: Donna Rice Quillen, Rodney Scott Armentrout, Mary Therese Jernigan, Steven Lee Stafford, Zhiyong Xia -

Patent number: 8645539Abstract: A content delivery network (CDN) for delivering content over the Internet is disclosed in one embodiment. The CDN includes a domain resolution service (DNS) server, caching servers and an Internet interface. The caching servers correspond to a plurality of addresses. The DNS server receives two domain resolution requests corresponding to a same domain and produces two different DNS solutions, each corresponding to a subset of caching servers. The interface receives domain resolution requests, including the two domain resolution requests, and transmits DNS solutions, including the two DNS solutions. The processing power is generally matched between the two DNS solutions.Type: GrantFiled: January 2, 2013Date of Patent: February 4, 2014Assignee: Limelight Networks, Inc.Inventors: Nils H.

Patent number: 8562259Abstract: A retaining wall system formed from a wire facing unit having an upstanding face section and a rearwardly extending floor section the rear end of which is provided with aligned, transversely extending, openings defined by upstanding U-shaped protuberances. The apertures in the forward portion of a geogrid can be seated over the protuberances and a connector strut interconnects the face section and floor section for providing support therebetween and for securing the geogrid to the floor section. The connector strut includes an elongated rigid rod having a curved first end that extends to a substantially right-angled bend, and a connector rod portion extends from the bend to a second end to secure the geogrid to the floor section.Type: GrantFiled: October 14, 2010Date of Patent: October 22, 2013Assignee: Tensar International CorporationInventors: Jon Robert Ridgway, Willie Liew, Robert Lloyd Talbot, Jeremy Lee Stafford
