    Abstract: This disclosure describes techniques for dynamically changing a user authorization with a service provider during an ongoing user session. The changing user authorization may be used to address changing confidence in an identity of a user consuming a service provided by the service provider. The changing user authorization may also be used to adjust a scope of a service to which a user has access. The present techniques may allow single-sign-on type protocols to accomplish the flexible and dynamic change-of-authorization functionality of some traditional protocols to handle ongoing client-server sessions, rather than simply revoking authorization for access to the service. For this reason, the present techniques are able to integrate advantages of traditional protocols with newer, single-sign-on-type protocols.

    Abstract: In one embodiment, an apparatus includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the apparatus to perform operations including receiving a user credential from a remote access client within a network and communicating the user credential to an authentication, authorization and accounting (AAA) server within the network. The operations also include receiving a user attribute from the AAA server and generating a contextual label based on the user attribute. The contextual label includes routing instructions associated with traffic behavior within the network. The operations further include advertising a control message, which includes the contextual label, to the remote access client.

    Abstract: A method is provided in one example embodiment and includes receiving a first request from a first user equipment by a first transport layer proxy located within an access network The first request includes a request to establish a user session between the first user equipment and a remote server. The method further includes establishing a first transport layer session between the first user equipment and the first transport layer proxy, establishing a second transport layer session between the first transport layer proxy and the remote server, and establishing a first control channel between the first transport layer proxy and a transport layer function manager within a core network. The method further includes sending session state parameters associated with the first transport layer session and the second transport layer session to the transport layer function manager using the first control channel.

    Abstract: An example method for distributed network address and port translation (NAPT) for migrating flows between service chains in a network environment is provided and includes distributing translation state for a flow traversing the network across a plurality of NAPT service nodes in the network, with packets belonging to the flow being translated according to the translation state, associating the flow with a first service chain at a flow classifier in the network, and updating the association when the flow migrates from the first service chain to a second service chain, with packets belonging to the migrated flow also being translated according to the translation state. The method may be executed at a pool manager in the network. In specific embodiments, the pool manager may include a distributed storage located across the plurality of NAPT service nodes.

    Abstract: A plurality of network nodes are deployed in a network, each network node configured to apply a service function to traffic that passes through the respective network nodes. A controller generates information for a service chain that involves application to traffic of one or more service functions at corresponding ones of the plurality of network nodes along a forward path through the one or more network nodes. The controller identifies one or more of the service functions within the service chain that is stateful. When one or more of the service functions of the service chain is stateful, the controller generates information for a reverse path through the one or more service nodes for the one or more stateful service functions. The controller binds a forward chain identifier for the forward path with a reverse chain identifier for the reverse path for the service chain.

    Abstract: A system of one embodiment allows for redirecting service and API calls for containerized applications in a computer network. The system includes a memory and a processor. The system processes a plurality of application workflows of a containerized application workload. The system then identifies at least one application workflow of the plurality of application workflows and at least one workflow-specific routing rule associated with the at least one application workflow. The system then determines at least one proxy server address for each identified application workflow based on the at least one associated workflow-specific routing rule. Then the system determines at least one proxy server address for each identified application workflow based on the at least one associated workflow-specific routing rule. The system then may communicate the at least one identified application workflow to the at least one proxy server using the at least one determined proxy server addresses.
