Abstract: Embodiments herein describe techniques for dynamically negotiating an SLA between a roaming device and a VN in an identity federation. Instead of an IDP having to individually negotiate with a VN to decide on an SLA before a user device roams to the VN, the parties can dynamically negotiate the SLA after the user device has detected the VN (but before the device is permitted to connect or associate with the VN). In one embodiment, when a roaming user device comes within wireless range of a VN, the roaming device receives an advertisement from the VN that indicates the current SLA (or SLAs) offered by the VN. The roaming device can compare this offered SLA to a stored SLA in an identity profile the device received from the IDP to determine whether to accept the offer. In another embodiment, the SLA is instead negotiated between VN and the IDP.

Abstract: A communication system in which DRA control is aided by RL. An example embodiment may control one or more buffer queues populated by downstream and/or upstream data streams. The egress rates of the buffer queues can be dynamically controlled using an RL technique, according to which a learning agent can adaptively change the state-to-action mapping function of the DRA controller while circumventing the RL exploration phase and relying on extrapolation of the already taken actions instead. This feature may result in at least two benefits: (i) cancellation of a performance penalty typically associated with RL exploration; and (ii) faster learning of the environment, as the learning agent can determine the performance metrics of many actions per state in a single occurrence of the state. In an example embodiment, the communication system may be a DSL system, a PON system, or a wireless communication system.
