The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 [2] for UMTS, in TS 36.331 [3] for LTE and in TS 38.331 [4] for 5G New Radio. RRC messages are transported via the PDCP-Protocol.
Microsoft also uses Azure Linux in Azure IoT Edge to run Linux workloads on Windows IoT, and as a backend distro to host the Weston compositor for WSLg. [7] In a similar approach to Fedora CoreOS, Azure Linux only has the basic packages needed to support and run containers. Common Linux tools are used to add packages and manage security updates.
PDCP provides its services to the RRC and user plane upper layers, e.g. IP at the UE or to the relay at the base station. The following services are provided by PDCP to upper layers: transfer of user plane data; transfer of control plane data; header compression; ciphering; integrity protection.
Dynamic RRM schemes adaptively adjust the radio network parameters to the traffic load, user positions, user mobility, quality of service requirements, base station density, etc. Dynamic RRM schemes are considered in the design of wireless systems, in view to minimize expensive manual cell planning and achieve "tighter" frequency reuse patterns, resulting in improved system spectral efficiency.
The 75th Ranger Regiment's Regimental Reconnaissance Company (formerly known as Regimental Reconnaissance Detachment, or RRD) is an elite special operations force that has been a member of Joint Special Operations Command (JSOC) since 2005.
Azure Sphere is an application platform with integrated communications and security features developed and managed by Microsoft for Internet Connected Devices.. The platform consists of integrated hardware built around a silicon chip: the Azure Sphere OS (operating system for Azure Sphere), an operating system based on Linux, and the Azure Sphere Security Service, a cloud-based security service.
Each application block addresses a specific cross-cutting concern and provides highly configurable features, which results in higher developer productivity. The Application Blocks in Enterprise Library are designed to be as agnostic as possible to the application architecture, for example the Logging Application Block may be used equally in a web, smart client or service-oriented application.
In February 2024, a malicious backdoor was introduced to the Linux build of the xz utility within the liblzma library in versions 5.6.0 and 5.6.1 by an account using the name "Jia Tan". [ b ] [ 4 ] The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution through OpenSSH on the affected Linux system.
