摘要： The disclosure relates to a method and request router (RR) to optimize content distribution in a Content Distribution Network (CDN) avoiding (unnecessary traffic towards the Content Provider) requesting the content to the origin server when the content is already available in one of the Delivery Nodes of the CDN. This is achieved by providing a path to a delivery node (DN) caching a requested content, in a content delivery network (CDN) comprising a plurality of DNs. The method comprises selecting a first DN caching the requested content. Upon determination that the first DN (90-1) has reached a maximum capacity, the method comprises selecting a second DN (90-2), which is not caching the requested content, for caching the requested content. The method comprises providing instructions, for use by the second DN, to fetch the requested content from the first DN using a reserved interface and providing a path to the second DN.

摘要： A method and request router (RR) are provided for dynamically pooling resources in a Content Delivery Network (CDN), for efficient delivery of live and on-demand content. The method comprises receiving, at the RR, a request for a content from a client, determining a content type associated with the request for the content, the content type being one of: live content and on-demand content. The method also comprises, based on the determined content type, dynamically electing, at the RR, delivery nodes at edge, region or core for content delivery and grouping the dynamically elected nodes into a resource pool, selecting a delivery node within the resource pool for delivering the content and sending a response to the client including an address of the delivery node selected within the resource pool to be used to get the requested content.

摘要： The disclosure relates to a method, that can be executed by an edge delivery node, a set-top-box or a user device, for providing to a user a higher resolution media segment by enhancing a low-resolution media segment. The method comprises obtaining the low-resolution media segment; using a neural network operative to enhance media segments to enhance the low-resolution media segment into the higher resolution media segment; and providing the higher resolution media segment to the user.

摘要： A method, Delivery Node, DN, and Content Delivery Network, CDN, are optimized to deliver content of different categories. The DN is operative to receive a request for a content, obtain a determination of whether or not a category of content is associated with the requested content and responsive to the determination that no category of content is associated with the requested content, forward the request for the content towards an origin server and upon receiving a response from the origin server serve the content. The CDN comprises a plurality of DNs, a data processing service operative to obtain, from the DNs, and assemble, data sets into training and validation data formatted to be used for training and validating a Neural Network, NN. The CDN comprises a NN training service, operative to train and validate the NN and a configuration service, operative to configure the plurality of DNs with the trained and validated NN.

摘要： A cloud management device determines that a virtual machine should be migrated from a first host to a second host, the virtual machine being associated with a virtual service, such as a virtual firewall, in the first host. The cloud management device verifies if functionality corresponding to the virtual service is available in the second host. If the required functionality is not available, a new virtual service is instructed to be instantiated in the second host. State synchronization can be performed between the virtual services in the first and second hosts. The cloud management device instructs the virtual machine to be instantiated in the second host.

摘要： According to one aspect, the teachings herein disclose a method and apparatus for a providing content over a secure connection to a subscriber device, where the content is advantageously securely delivered from a cache local to the telecommunication network. Such operation is based on intercepting a secure connection request from the subscriber device and establishing a corresponding secure session between the subscriber device and a local network data center, rather than the remote content provider targeted by the request.

摘要： Temporal metadata associated with media content drives bilateral interaction between a media server and an IPTV control server during streaming of that content from the media server. Specifically, the metadata is encoded to indicate, and associate together, a defined point in the media content's presentation timeline and a defined operation, such as the fetching of supplemental media content or the sending of a notification. The media server inspects this metadata and, based on that inspection, notifies the IPTV control server when the defined point has been reached in the context of streaming the media content. Responsive to receiving this notification, the IPTV control server inspects the metadata to identify the operation associated with the notified point in the content's timeline. The IPTV control server then initiates the performance of the identified operation and returns a response to the media server that pertains to such performance.

摘要： A method, Request Router and Traffic Monitor for monitoring a Content Delivery Network effecting requests routing toward delivery nodes (DNs) without using a load balancer and achieving high availability. Iteratively, for each delivery node, sending a monitoring request to the delivery node. If a response indicative of success of the monitoring request is received from the delivery node before the end of a first time interval, setting a status of the delivery node to indicate success. If a response indicative of failure is received before the end of the first time interval, setting the status to indicate failure. If no response is received before the end of the first time interval, setting the status to indicate indetermination. Iteratively, at a second time interval, taking a snapshot of the statuses of the delivery nodes and producing a list of DNs with their statuses to be sent to the RR.

摘要： The disclosure relates to an Edge Cloud Platform (ECP) and a method executed in the ECP, for providing a low-latency, distributed, multi-user application. The method comprises determining a first location of a first group of users requesting access to the multi-user application and deploying the multi-user application in a first Point of Presence (PoP) in a first Service Provider (SP) domain operative to serve the first group of users. The method comprises determining a second location of a second group of users requesting access to the multi-user application and deploying a proxy of the multi-user application in a second PoP in a second SP domain operative to serve the second group of users. The method comprises, upon determining that a Software License Agreement (SLA) exists between the first and second SPs, establishing a tunnel for linking the multi-user application and the proxy of the multi-user application, thereby providing the low-latency.
