Abstract: A request router is disclosed for a multi-tier Content Delivery Network (CDN), each tier corresponding to a hierarchical layer of the CDN. The request router includes processing circuitry configured to: receive, from a first delivery node of a hierarchical layer of the CDN, a routing request to bypass the first delivery node for content delivery to a user equipment; and as a result of receiving the routing request to bypass the first delivery node for the content delivery to the user equipment, select at least a second delivery node for the content delivery to the user equipment.

Abstract: 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.

Abstract: A technique for monitoring activity in a content delivery network is disclosed.

Abstract: The disclosure relates to a method, an apparatus and a non-transitory computer readable media for service placement in a multi-access/mobile edge computing (MEC) system, comprising: iteratively, for each subset of services or applications su of each type u, u being element of a set of U of unique V2X services or applications sorted in order of latency requirement: calculating an average latency for the subset of services or applications su; selecting a node c providing a latency smaller than or equal to the calculated average latency and providing enough capacity to run the subset of services or applications su; placing the subset of services or applications su on the node c; and updating a list of available nodes.

Abstract: The disclosure relates to content delivery network and to methods and network nodes enabling the content delivery network to handle unexpected surges of traffic by computing and using a traffic prediction for a content for at least one delivery node.

Abstract: A method of HTTP redirection is provided for scenarios where a manifest file for media content contains a relative URL. A request router or other network device encapsulates the content manifest file within a root manifest file. The root manifest file contains a base URL that points to the location of the content and a media link that points to the requested content manifest.

Abstract: 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.
