Each route is characterized by one or more of locality and residency. The plurality of routes are specified for a plurality of policies. An application running on an end user device requests a policy chosen from the plurality of policies. A route of the plurality of routes corresponding to the policy for the end user device is returned. The plurality of policies control the residency for the plurality of cloud services and the plurality of routes. Communication is performed via the route between the application and a cloud service according to the policy.

Residency control for cloud services and routes in cloud-based multi-tenant system

A method and system for policy-driven traffic management in cloud-based multi-tenant systems is disclosed. Routes delivers services to end user devices. The routes are specified for policies. The policies specify residencies for the routes, cloud services, and data storage. An application running on an end user device selects a policy and a cloud service. A route corresponding to the policy, a residency specified by the policy, and the cloud service is returned to the application. An operation of the end user device in compliance with the policies is monitored to generate telemetry. An access resource server receives a non-compliance with the policy, and identify new routes, policies and configuration for remediation.

Policy-based traffic and residency management

A cloud-based multi-tenant system for policy-driven locality route and traffic management is disclosed. The cloud-based multi-tenant system includes a plurality of routes through the cloud-based multi-tenant system to deliver services to a plurality of end user devices. Each route is characterized by one or more of locality and residency. The plurality of routes are specified for a plurality of policies. An application running on an end user device requests a policy chosen from the plurality of policies. A route of the plurality of routes corresponding to the policy, traffic rules, and route maps corresponding to the policy for the end user device are returned. Communication is performed via the route between the application and a cloud service according to the policy. Compliance with the policy is tested for locality and residency, telemetry according to the testing is reported, and the plurality of routes is updated based upon the telemetry.

Dynamic configuration of policy based routes using traffic rules and route maps

A method and system for policy-driven traffic management in cloud-based multi-tenant systems is disclosed. Each end user device within each tenant is provided policies to specify priority based upon, for example, end-to-end performance, bandwidth or service capacity, service or link availability, or security. Different routes are provided for each policy. An application can request a route to an Internet service according to the policy to be assigned a route.

Policy-driven client and destination priority

A method and system for policy-driven locality management of routes in cloud-based multi-tenant systems is disclosed. Policies are provided to end user devices to specify one or more locality and residency to either favor or avoid. Routes are provided to each end user device for the policies. When an application specifies a policy to use for a cloud service, the appropriate route(s) are provided to provide connectivity. Testing of the route is performed for compliance to provide telemetry. Where non-compliance is found, the routes are updated and distributed to the various end user devices.

Policy-driven data locality and residency

Systems and methods for gathering distributed information to improve routing that uses Anycast for assigning deliveries between a number of geographically-distant points of presence (POPs) are disclosed. The POPs share the same Internet protocol (IP) address. According to Anycast resolution, the Internet aids in assigning a content request initially to a POP. Delivery statistics are gathered from deliveries a the number of POPs and possibly other sources. Where it is determined that Anycast found the wrong POP, the content request is reassigned to another POP.

Enhanced anycast for edge server selection

In various aspects, provided herein are systems, methods and computer-program products for delivering content objects over the Internet from a content delivery network to end-user systems. The systems, methods and products described herein optionally utilize one or more techniques for reducing the delay associated with obtaining non-cached content objects from their respective origin servers, including by re-using existing open connections, by making use of a TCP hand-off technique and by transmitting updates to system digests simultaneous with the exchange of keepalive signals between servers.

Connection digest for accelerating web traffic

A method of distributing partial content objects may include receiving a request for a content object with a content identifier. The method may further include sending the content identifier from an edge server to a distribution server that is configured to determine that the content object is a candidate for partial object distribution, determine a first portion of the content object, and cause the first portion of the content object to be sent to the edge server. The method may additionally include caching, at the edge server, a second portion of the content object, where the first portion of the content object may include the second portion of the content object and a remaining portion of the content object, and where the second portion of the content object is smaller than the first portion of the content object.

Partial object distribution in content delivery network

A method and system for flexibly processing content objects is disclosed. A content object is stored on one of a plurality of storage devices. A request is received for the content object. Information corresponding to the requested object (e.g., a unique identifier) is transmitted to one or more content directories. A response is received from a first content directory indicating a location of the content object. The content object is requested from the first location, and at least part of the content object is received.

Multicast mapped look-up on content delivery networks

A content delivery network (CDN) performs time varying traffic allocation. The network includes: one or more edge servers that store content corresponding to a domain name that is associated with a content provider, and are configured to deliver the content to end users in response to requests received at the edge servers from the end users; analytics information characterizing the CDN; and a traffic engine that periodically evaluates a service function as having a serve value or a shunt value for the domain name, based at least in part on the analytics information. The traffic engine transmits one or more IP addresses of the edge servers to an interface to a domain name service (DNS) while the service function has the serve value for the domain name; and transmits alternate domain name information of a different network to the interface while the service function has the shunt value.

Time based CDN traffic allocation

A method for processing content objects with resources associated with a content delivery network (CDN) having a plurality of geographically distributed points of presence (POPs) is disclosed. The resources are enrolled to be accessible from the CDN. Each resource is categorized using tags that categorize the resources. Selection of a policy from a plurality of policies is received, where the plurality of policies define processes to perform on content objects. The selected policy includes an applicability criteria and a call to the resource. Metadata is received at the CDN, the metadata being related to a content object, a requester of the content object and/or a provider of the content object. It is determined that the policy is applicable through analysis of the metadata and/or applicability criteria. The resource is called according to the call in the policy to cause the resource to perform specified processing on the content object.

Policy based processing of content objects in a content delivery network using mutators

Systems and methods for gathering distributed information from a number of data agents for a messaging queue, which is coupled to a number of processing subscribers is disclosed. The data agents provide their gathered information to an interface defined by an API. The gathered data may be reformatted or further processed before adding the gathered information to the messaging queue. A number of processing subscribers listen to a content stream produced by the messaging queue to receive data they have subscribed to. Once the processing subscriber receives the content stream, the processing subscriber applies algorithms to the content stream to perform one or more other functions. For instance, the processing subscriber can feed back processed data into the messaging queue and/or perform an action based, at least in part, upon the content stream. Information in various degrees of processing and aggregation can be passed through any number of cycles in a processing ring to allow for a clearinghouse of information to flow in real time or near real time.

Real-time message queuing for a processing ring

A method for populating edge servers within a content delivery network (CDN) having a plurality of points of presence (POPs) is disclosed. A first function is performed that gathers popularity information for a content object. Popularity trends for the popularity information are determined through analysis with historical popularity information. A number of copies of the content object for each of the plurality of POPs is determined. The number is passed as a variable to a second function. The second function is performed that adds or deletes copies of the content object for each of the plurality of POPs as a function of the popularity trend and the number.

Content replication workflow in content delivery networks

A method for processing content objects with a content delivery network (CDN) having a plurality of geographically distributed points of presence is disclosed. Selection of a policy is received from a plurality of policies, where the plurality of policies define processes to perform on content objects stored at the CDN. Each policy includes an applicability criteria and a storage disposition. Metadata is received at the CDN, the metadata characterizing a content object, a requester of the content object and/or a provider of the content object. The content object is received for storage at the CDN. A policy and other policies are determined to be applicable to the content object through analysis of the metadata and/or the applicability criteria. Overlap is resolved between the policy and the other policies found applicable to the content object. The processing of the policy is performed on the content object.

Policy management for content storage in content delivery networks

Techniques for the distribution of content objects in a content delivery network (CDN) are disclosed. A CDN distribution server detects a content object's availability and determines whether the content object is a candidate for distribution. The distribution server detects the availability of the content object in response to a provider making new or updated content available at a content site or a location within the CDN. The distribution server obtains identifying information for a candidate content object and determines a select portion of the content object to be distributed within the CDN. The select portion can be a predetermined number of bytes located at a predetermined position in the content object, the size and location of which may be determined according to content-specific mapping data. The distribution server pushes the select portion of the content object to one or more groups of CDN edge servers absent an end-user request.
