Abstract: Some embodiments of the invention provide, for a RAN (radio access network), a method of rapidly upgrading multiple machines distributed across multiple cell sites, each particular machine of the multiple machines executing one or more base station applications. The method downloads a second boot disk for each of the multiple machines at each of the multiple cell sites, the second boot disk including an upgraded version of a first boot disk currently used by each of the multiple machines. For each particular machine, the method (1) powers off the particular machine, (2) creates a copy of data stored by a data disk of the particular machine to preserve data stored currently on the data disk, (3) replaces the first boot disk of the particular machine with the second boot disk that is the upgraded version of the first boot disk, and (4) powers on the particular machine.

Abstract: Some embodiments provide various methods for offloading operations in an O-RAN (Open Radio Access Network) onto control plane (CP) or edge applications that execute on host computers with hardware accelerators in software defined datacenters (SDDCs). At the CP or edge application operating on a machine executing on a host computer with a hardware accelerator, the method of some embodiments receives data, from an O-RAN E2 unit, to perform an operation. The method uses a driver of the machine to communicate directly with the hardware accelerator to direct the hardware accelerator to perform a set of computations associated with the operation. This driver allows the communication with the hardware accelerator to bypass an intervening set of drivers executing on the host computer between the machine's driver and the hardware accelerator. Through this driver, the application in some embodiments receives the computation results, which it then provides to one or more O-RAN components (e.g., to the E2 unit that provided the data, another E2 unit or another control plane or edge application).

Abstract: Described herein are systems, methods, and software to manage the encapsulation of layer two communications across computing sites. In one example, a gateway at a first computing site may receive an encapsulated packet from a second gateway at a second computing site. After receiving the encapsulated packet, the gateway decapsulates the encapsulated packet and determines that the decapsulated packet satisfies MSS criteria. The gateway further, in response to determining that the decapsulated packet satisfies the MSS criteria, modifies an MSS option associated with the decapsulated packet to a maximum value and forwards the decapsulated packet to a destination virtual node in the first computing site.
