The Data Plane Development Kit (DPDK) is an open source software project managed by the Linux Foundation. It provides a set of data plane libraries and network interface controller polling-mode drivers for offloading TCP packet processing from the operating system kernel to processes running in user space .
This diagram represents five contiguous memory regions which each hold a pointer and a data block. The List Head points to the 2nd element, which points to the 5th, which points to the 3rd, thereby forming a linked list of available memory regions. A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation.
Reliably sending a payload of data over a communications network requires sending more than just the payload itself. It also involves sending various control and signalling data required to reach the destination. This creates a so-called protocol overhead as the additional data does not contribute to the intrinsic meaning of the message. [5] [6]
Thread Control Block (TCB) is a data structure in an operating system kernel that contains thread-specific information needed to manage the thread. [1] The TCB is "the manifestation of a thread in an operating system." Each thread has a thread control block. An operating system keeps track of the thread control blocks in kernel memory. [2]
The Environment Modules system is a tool to help users manage their Unix or Linux shell environment, by allowing groups of related environment-variable settings to be made or removed dynamically. Modules has been around since the early 1990s [ 1 ] and is used at some of the largest computer centers [ 2 ] to deploy multiple versions of different ...
In computer science, read-copy-update (RCU) is a synchronization mechanism that avoids the use of lock primitives while multiple threads concurrently read and update elements that are linked through pointers and that belong to shared data structures (e.g., linked lists, trees, hash tables).
RocksDB is a high performance [2] [3] [4] [5] [6] embedded database for key-value data. It is a fork of Google's LevelDB optimized to exploit multi-core processors ...
Xenomai is a software framework cooperating with the Linux kernel to provide interface-agnostic, hard real-time computing support to user space application software seamlessly integrated into the Linux environment. The Xenomai project was launched in August 2001.
