20080215718 | Policy-based content delivery network selection - In a framework wherein resources of a content provider may be delivered to clients from different domains, a method distributes the requests based on content-provider policies. In some cases, the domains include at least two distinct content delivery network (CDN) domains. The domains may include a content provider domain. Responsive to a request, either the content provider domain or one of the two CDN domains is selected, the selection being based at least in part on one or more policies set by the content provider. | 09-04-2008 |
20090276842 | Load-Balancing Cluster - A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member. | 11-05-2009 |
20100332664 | LOAD-BALANCING CLUSTER - A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member. | 12-30-2010 |
20110145386 | Policy-Based Content Delivery Network Selection - In a framework wherein resources of a content provider may be delivered to clients from different domains, a method distributes the requests based on content-provider policies. In some cases, the domains include at least two distinct content delivery network (CDN) domains. The domains may include a content provider domain. Responsive to a request, either the content provider domain or one of the two CDN domains is selected, the selection being based at least in part on one or more policies set by the content provider. | 06-16-2011 |
20120072525 | Extending Caching Network Functionality To An Existing Streaming Media Server - A content delivery network (CDN) includes multiple cluster sites, including sites with streaming media servers, caching servers and storage devices accessible to the caching servers for storing streaming content. Interface software is configured to initiate retrieval, by a caching server, of electronic streaming resources from the one or more storage devices in response to requests for the electronic streaming resource received by the streaming media server. | 03-22-2012 |
20130159472 | CONTENT DELIVERY NETWORK - A content delivery network (CDN) includes a control core; and a plurality of caches, each of said caches constructed and adapted to: upon joining the CDN, obtain global configuration data from the control core; and obtain data from other caches. Each of the caches is further constructed and adapted to, having joined the CDN, upon receipt of a request for a particular resource: obtain updated global configuration data, if needed; obtain a customer configuration script (CCS) associated with the particular resource; and serve the particular resource in accordance with the CCS. | 06-20-2013 |
20130159473 | CONTENT DELIVERY NETWORK - A device is operable in a content delivery network (CDN). The device has a cache server mechanism constructed and adapted to: upon joining the CDN, obtain global configuration data from a control core of the CDN; and, having joined the CDN, obtain updated global configuration data, if needed; and obtain customer configuration information associated with at least one customer of the CDN. The device serves a particular resource associated with a particular customer of the CDN in accordance with (i) the global configuration data, and (ii) customer configuration information obtained in and associated with the particular customer. | 06-20-2013 |
20130173806 | LOAD-BALANCING CLUSTER - A load-balancing cluster includes a switch having ports; and servers connected to at least some of the ports. The servers are each addressable by the same virtual Internet Protocol (VIP) address. A first server of the plurality of servers establishing a Transmission Control Protocol (TCP) connection with a client computer, and, in response to a resource request received by the first server from the client computer for a particular resource, if the first server does not have a copy of the particular resource it queries one or more peers regarding the particular resource. Based at least in part on responses from the peers, the first server either: obtains the particular resource from a peer; or migrates the TCP connection to a peer; or serves the particular resource to the client request through a second server. | 07-04-2013 |
20130174177 | LOAD-AWARE LOAD-BALANCING CLUSTER - A load-aware load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to determine the particular server's own measured load; convert the particular server's own measured load to a corresponding own particular load category of a plurality of load categories; provide the particular server's own particular load category to other servers of the plurality of servers; obtain load category information from other servers of the plurality of servers; and maintain, as an indication of server load of each of the plurality of servers, the particular server's own particular load category and the load category information from the other servers. | 07-04-2013 |
20130332613 | LOAD-BALANCING CLUSTER - A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member. | 12-12-2013 |
20140372588 | Request-Response Processing in a Content Delivery Network - A computer-implemented method in a content delivery network (CDN) includes, responsive to a request, determining a particular sequencer to handle the request, the particular sequencer includes a sequence of one or more handlers. The request is processed in accordance with the particular sequencer by invoking the one or more handlers. | 12-18-2014 |
20140372589 | Customer-Specific Request-Response Processing in a Content Delivery Network - A computer-implemented method in a content delivery network (CDN) includes, at a mechanism in said CDN: responsive to a request, determining a particular sequencer to handle the request, the particular sequencer comprising a sequence of one or more handlers, wherein the request is associated with a particular customer of said CDN and wherein a first at least some of the one or more handlers in the particular sequence are determined based on the particular customer; and processing the request in accordance with the particular sequencer by invoking the one or more handlers. | 12-18-2014 |
