Abstract: A processing system of an edge exchange point including at least one processor may receive, from a cloud service provider a request to allocate a first tag to communications between the cloud service provider and a first telecommunication network, transmit an acceptance of the request to allocate the first tag to the communications between the cloud service provider and the first telecommunication network, obtaining a first packet containing the first tag from the cloud service provider, and transmit the first packet to the first telecommunication network in accordance with the first tag.

Abstract: Concepts and technologies are disclosed herein for creating cross-service chains of virtual network functions in a wide area network. A controller can receive a chain request from a requestor. The chain request can specify functionality that is to be included in a service chain. The functionality can include a first function and a second function. The controller can compute a route associated with the service chain. The route can specify a first site that hosts a first service that provides the first function and a second site that hosts a second service that provides the second function. A first virtual network function can be located at the first site and a second virtual network function can be located at the second site. The controller can configure edge devices and forwarding devices to various entities at the two sites to enable the cross-service virtual network function chain.

Abstract: A method, computer-readable medium, and apparatus for supporting services for customer traffic using edge clouds are disclosed. For example, a processing system may receive an indication of a set of customer devices of a customer of a network provider and an indication of a service of an edge cloud to be applied to customer traffic of the customer devices, support configuration of a network of the network provider to support a customer segment for the customer including configuration of a gateway of the network and a switch of the network that is associated with the edge cloud, support configuration of a virtual network between the switch and an edge cloud element supporting the service, and support configuration of the switch to support an association of the customer segment and the virtual network for supporting routing of the customer traffic to the service via the virtual network.

Abstract: According to one aspect disclosed herein, a system can include a set of node peers, including a first subset implemented in software and a second subset implemented in hardware. The first subset can include a software node. The second subset can include a hardware node that includes a hardware cache, a processor, and a memory that stores computer-executable instructions. The hardware node can receive, from a network, a packet, and can determine if data that identifies a path associated with the packet is stored in the hardware cache. If not, the hardware node can query the software node to identify the path associated with the packet, and can receive, in response from the software node, the data that identifies the path, which then can be stored in the hardware cache. The hardware node can forward, along the path, the packet to a network element.

Abstract: Methods, systems, and apparatuses, among other things, may direct client requests to an Edge Cloud location satisfying application requirements associated with the request. Moreover, a domain name service (DNS) query may be received, one or more requests associated with DNS query may be determined, a server may be identified based on the one or more requests, and the DNS query may be redirected to the identified server.
