Abstract: A method includes creating a session token including a session identifier and a current node, capturing a set of queries in a cache from a client device at the current node associated with the session identification, receiving a request from the client for data access at a second node wherein the request includes the session token, transferring a subset of data records from the current node to the second node, wherein the subset of data records is selected based on the session identifier and the set of queries; and granting access to the client to the second node.

Abstract: A system that determines whether a trigger has occurred within a cloud infrastructure. The system, in response to determining that a trigger has occurred, extracts characteristics from one or more virtual network functions (VNFs) of a service chain. The system, in response to extracting characteristics from the one or more VNFs, determines rehoming actions for each of the one or more VNFs. The system, in response to determining rehoming actions, predicts a rehoming delay or a chain downtime for each of the rehoming actions for each of the one or more VNFs. The system determines an optimal rehoming action from the rehoming actions for at least one of the one or more VNFs using the rehoming delay or the chain downtime for each rehoming action of the rehoming actions. The system performs the optimal rehoming action for the at least one of one or more VNFs.

Abstract: The technologies described herein are generally directed to modeling radio wave propagation in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include, for a network application, identifying, by a system comprising a processor, a characteristic value of a performance characteristic associated with an uplink connection enabled via a network of a user equipment to application server equipment hosting the network application. The method can further include, based on the characteristic value and a criterion, selecting, by the system, a first packet size for the uplink connection. The method can further include communicating, by the system, to the user equipment, the first packet size for use with the uplink connection.
