Abstract: In some examples, a software-defined network (SDN) controller determines a link aggregation (LAG) configuration for a node in the SDN that is controlled by the SDN controller. The LAG configuration is based on hardware capability information and dynamic network traffic information of the SDN. The SDN controller can further instruct the node to forward traffic in accordance with the LAG configuration.

Abstract: Implementations of the disclosure are directed to using a distributed ledger network to synchronize configuration changes across a network of servers that provide authentication, authorization, and accounting (AAA). In some implementations, a method includes: receiving, at a first server that provides AAA of users that access a network, a user request to update a configuration of a database of the first server, the database including authentication credentials for users that access the network, in response to receiving the user request, transmitting a transaction to the distributed ledger network for validation, the transaction comprising a request by the first server for each server of the distributed ledger network to update their respective database configuration in accordance with the user request; and after the transaction is validated by the distributed ledger network, the first server updating its database configuration in response to receiving the update comprising the validation of the transaction.

Abstract: Methods, systems, and storage mediums that can allow for automatic re-routing of network traffic in software-defined networks. In some examples, instructions can be provided to network switches in a software-defined network to initially route network traffic along a first flow route. The instructions can further instruct the network switches to automatically re-route the network traffic along a second flow route at a later time.

Abstract: In some examples, a maximum transmission unit (MTU) is installed by a Software-Defined Network (SDN) controller on a controlled network node for traffic along a datapath in an SDN. The installed MTU can, for example, be selected from MTU sizes in an MTU database for nodes along the datapath. For example, the installed MTU can be selected as the largest allowable MTU size based on the nodes of the datapath.
