Publication number: 20220094669Abstract: A controlled content system for providing a controlled and contained environment that is remotely accessible is disclosed. An application on the end user device is modified to allow certain sites and services to be mediated in a mid-link server. The app uses policies to know when to access the mid-link server for the controlled and contained environment. Policies can specify the type of processing performed on the mid-link server. Some embodiments support the app selectively using the mid-link server for mediated sites and services. A client spoofer at the mid-link server spoofs direct interaction with the certain sites and the services as if the end user device was directly interacting with the plurality of remote services.Type: ApplicationFiled: May 12, 2021Publication date: March 24, 2022Applicant: Netskope, Inc.Inventor: BRADLEY B.

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.

Patent number: 9069720Abstract: A method of providing media at multiple bit rates using partial object caching may include receiving, from a first user device, a first request for a media object encoded at a first bit rate; providing the first portion of the media object to the first user device; and caching, in a partial object cache, the first portion of the media object. The method may additionally include receiving, from a second user device, a subsequent request for the media object encoded at the first bit rate; providing the first portion of the media object as retrieved from the partial object cache; and receiving a request for the media object encoded at a second bit rate. The method may further include modifying the request for the media object encoded at the second bit rate to instead request a second portion of the media object at the second bit rate.Type: GrantFiled: January 2, 2013Date of Patent: June 30, 2015Assignee: Limelight Networks, Inc.Inventors: Bradley B.

Patent number: 9009272Abstract: A method for handling content requests received in a CDN using an intermediate server may include maintaining a virtual file server that provides virtualized access to content in multiple POPs throughout the CDN, receiving a content request sent to the CDN, making a local request to the virtual file server for the content, where the specialized virtual file server may determine that the content is stored in a second POP that is remotely located from the first POP, and the specialized virtual file server may retrieve the content from the second POP and provide the content to the intermediate server as though it were stored locally in the first POP. The method may also include receiving the content from the specialized virtual file server, where the specialized virtual file server makes the requested content appear to be a locally-stored file to an operating system of the intermediate server.Type: GrantFiled: December 13, 2013Date of Patent: April 14, 2015Assignee: Limelight Networks, Inc.Inventors: Mohan I.

Patent number: 8965997Abstract: Content delivery networks (CDNs) deliver content objects for others is disclosed. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When an edge server does not have a copy of the content object from the URI, information is successively passed to ancestor servers within a hierarchy until the content object is found. There can be different hierarchies designated for different URIs or times at which requests are received. Once the content object is located in the hierarchical chain, the content object is passed back down the chain to the edge server for delivery.Type: GrantFiled: March 3, 2014Date of Patent: February 24, 2015Assignee: Limelight Networks, Inc.Inventors: Bradley B.

Patent number: 8750155Abstract: Techniques for modifying the performance of a transport layer protocol in response to a request for content are disclosed. A connection can be established between a content distribution server and an end user computer according to preconfigured parameters. When a request for content is received over the connection, the content distribution server can determine one or more parameters relating to the performance of the connection using information from the request. The content distribution server can modify the connection at the transport layer according to the one or more parameters. Thereafter, the transport layer can manage delivery of the requested content to the end user computer in accordance with the modified parameters. In various embodiments, the content distribution server includes a modified TCP protocol stack which adjusts timing, pacing, and buffer allocation associated with a connection in response to requests from an application-layer data source.Type: GrantFiled: August 27, 2012Date of Patent: June 10, 2014Assignee: Limelight Networks, Inc.Inventors: Bradley B.

Publication number: 20140108674Abstract: A method and system for delivering content with a content delivery network (CDN) to a user computer is disclosed. After an initial request to a point of presence (POP) of the CDN for the location of the content object, an Anycast Internet protocol (IP) address is assigned. The user computer requests the content object which may find its way to the same or a different POP depending on what is closer in Internet terms. The request returns a POP-specific IP in a redirect such that the request resolves to the POP referenced in the immediately preceding sentence. One or more edge servers deliver the content object to the user computer.Type: ApplicationFiled: October 7, 2013Publication date: April 17, 2014Applicant: LIMELIGHT NETWORKS, INC.Inventors: Jason Eggleston, Bradley B. Harvell, Mohan I. Kokal

Patent number: 8683002Abstract: One or more content delivery networks (CDNs) that deliver content objects for others is disclosed. Content is propagated to edge servers through hosting and/or caching. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When a particular edge server does not have a copy of the content object from the URI, information is passed to another server, the ancestor or parent server to find the content object. There can be different parents servers designated for different URIs. The parent server looks for the content object and if not found, will go to another server, the grandparent server, and so on up a hierarchy within the group. Eventually, the topmost server in the hierarchy goes to the origin server to find the content object. The origin server may be hosted in the CDN or at a content provider across the Internet.Type: GrantFiled: January 2, 2013Date of Patent: March 25, 2014Assignee: Limelight Networks, Inc.Inventors: Bradley B.

Patent number: 8626876Abstract: An intermediate server for handling content requests received from edge servers in a Content Delivery Network (CDN) and accessing and processing content distributed throughout the CDN may include a port that receives a content request from an edge server in a same Point-of-Presence (POP) including a URI. The ICPS may also include a content processor communicatively coupled to the port and configured to perform a processing function on the requested content to produce processed content for delivery to the edge server. The ICPS may further include a CDN content interface that provides virtualized access to content files accessible using URIs throughout the CDN and configured to receive a portion of the requested content using the URI stored in a second POP, and provide the requested content to the content processor, wherein the requested content comprises the portion of the requested content.Type: GrantFiled: November 28, 2012Date of Patent: January 7, 2014Assignee: Limelight Networks, Inc.Inventors: Mohan I.
