Abstract: Some embodiments of the invention provide a method for a PIM (passive intermodulation interference) detection RAN (radio access network) application deployed across one or more RICs (RAN intelligent controllers) for detecting PIM in a RAN including multiple RAN base stations for servicing multiple users located across multiple regions, each region including at least one RAN base station. The method is performed for a particular region serviced by a particular RAN base station. The method detects (1) high uplink noise for the particular region and (2) antenna imbalance for the particular region. Based on said detection, the method determines whether high KPI (key performance indicator) impact is detected for the particular region. When high KPI impact is detected for the particular region, the method generates a PIM alert to notify an operator of the particular RAN base station that services the particular region that PIM is detected for the particular region.

Abstract: This disclosure is directed to methods and system for intelligent roaming of user equipment (“UE”) of a home network onto a visited network. The methods and systems monitor performance of voice and data services for UEs in coverage areas of edge cell sites of the home network. The methods and systems determine which UEs in the coverage areas of the edge cell sites to roam on the visited network based on decreases in voice and data services. The UEs in the coverage areas selected for roaming are pushed to roam on the visited network by sending a signal that instructs selected UEs to switch into roaming mode while the UEs are still in the coverage areas of the edge cell sites.

Abstract: A method is provided for a hyper-converged storage-compute system to implement an active-active failover architecture for providing Internet Small Computer System Interface (iSCSI) target service. The method intelligently selects multiple hosts to become storage nodes that process iSCSI input/output (I/O) for a target. The method further enables iSCSI persistent reservation (PR) to handle iSCSI I/Os from multiple initiators.

Abstract: Some embodiments provide a method for performing radio access network (RAN) functions in a cloud at a user-level tracing application that executes on a machine deployed on a host computer in the cloud. The method receives data, via a RAN intelligent controller (RIC), from a RAN component. The method uses the received data to generate information related to traffic performance for at least one user. The method provides the generated information to the RIC.

Abstract: Certain Embodiments described herein relate to configuring the network-storage stack of two devices (e.g., physical or virtual) communicating together (e.g., an initiator and a target, as defined below) with Internet Small Computer Systems Interface (iSCSI) extension for remote direct memory access (RDMA) iSER, which is a protocol designed to utilize RDMA to accelerate iSCSI data transfer. The iSER protocol is implemented as an iSER datamover layer that acts as an interface between an iSCSI layer and an RDMA layer of the network-storage stacks of the two devices. Using iSER in conjunction with RDMA allows for bypassing the existing traditional network protocol layers (e.g., TCP/IP protocol layers) of the devices and permits data to be transferred directly, between the two devices, using certain memory buffers, thereby avoiding memory copies taking place when the existing network protocol layers are used.

Abstract: System and method for writing updated versions of a configuration data file for a distributed file system in a storage system uses a directory renaming operation to write a new updated version of the configuration data file using the latest version of the configuration data file and a target directory. After the latest version of the configuration data file is modified by a particular host computer in the storage system, the modified configuration data file is written to a temporary file. The directory naming operation is then initiated on the temporary file to change the directory for the temporary file to the target directory. If the directory renaming operation has failed, a retry is performed by the particular host computer to write the new updated version of the configuration data file using a new latest version and a new target directory.
