Disclosed are various embodiments for a distributed and synchronized core in a radio-based network. In one embodiment, a first radio access network (RAN)-enabled edge server at a first edge location is configured to perform a set of distributed unit (DU) functions for a radio-based network. The first RAN-enabled edge server is also configured to perform a set of core network functions and a set of centralized unit (CU) functions for the radio-based network. State associated with the set of core network functions and the set of CU functions is synchronized between the first RAN-enabled edge server and another server.

Distributed and synchronized network core for radio-based networks

Disclosed are various embodiments for automated deployment and management of distributed units (DUs) in a radio-based network. In one embodiment, it is determined to deploy a radio-based network at least partially using infrastructure of a cloud provider network. A radio access network (RAN)-enabled edge server of the cloud provider network is deployed to a physical location of the radio-based network. The RAN-enabled edge server is configured to perform a set of distributed unit (DU) functions for the radio-based network.

Automated deployment and management of distributed units in radio-based networks

Systems and methods are described for implementing an event tracing system for an open radio access network ('RAN'). A RAN implementation may be distributed across multiple components, including both special-purpose components such as radio units and general purpose components such as local or cloud-based servers. A RAN event tracing system may thus be used to troubleshoot issues with the RAN implementation by collecting information from distributed components regarding events that occur on these components during the translation of data into radio signals and vice versa. The RAN event tracing system may be used to search for events associated with a particular identifier, such as a radio network temporary identifier, and to display representations of radio frames that were generated by the components and display information regarding the events that led to the placement of particular resource elements onto the radio frames.

Radio access network event tracing system

A control plane server of a virtualized computing service determines that connectivity is to be established between a first portion and a second portion of a distributed application. The first portion runs at a first edge location of a provider network, and the second portion runs at a second edge location. The control plane server transmits metadata associated with the second edge location to a connectivity manager at the first edge location. The metadata is used to establish a secure network channel between the connectivity manager and the second edge location. A message from the first portion of the distributed application is sent to the second portion via the channel.

Managed connectivity between cloud service edge locations used for latency-sensitive distributed applications

State information of a radio-based application, used to process messages of the application, is made accessible from a first compute instance and a second compute instance at a virtualization server. The first instance is assigned to process a first portion of a workload of the application, including a message which comprises a result of a network function executed at a network function accelerator of the server. In response to determining that a condition for migrating workload from the first compute instance has been met, an additional message of the first portion is directed to the second compute instance. The second compute instance processes the additional message using the state information.
