39 Application Programming Interface
42 Linux* kernel Address-Space Layout Randomization
45 Berkeley Software Distribution
51 Classless Inter-Domain Routing
54 The control plane is concerned with the routing of packets and with
55 providing a start or end point.
58 A core may include several lcores or threads if the processor supports
62 A set of libraries provided by the DPDK, including eal, ring, mempool,
63 mbuf, timers, and so on.
66 Central Processing Unit
69 Cyclic Redundancy Check
72 In contrast to the control plane, the data plane in a network architecture
73 are the layers involved when forwarding packets. These layers must be
74 highly optimized to achieve good performance.
77 Dual In-line Memory Module
80 A documentation generator used in the DPDK to generate the API reference.
83 Data Plane Development Kit
86 Dynamic Random Access Memory
89 The Environment Abstraction Layer (EAL) provides a generic interface that
90 hides the environment specifics from the applications and libraries. The
91 services expected from the EAL are: development kit loading and launching,
92 core affinity/ assignment procedures, system memory allocation/description,
93 PCI bus access, inter-partition communication.
99 Field Programmable Gate Array
108 High Precision Event Timer; a hardware timer that provides a precise time
109 reference on x86 platforms.
124 Internet Protocol version 4
127 Internet Protocol version 6
130 A logical execution unit of the processor, sometimes called a *hardware
134 Kernel Network Interface
155 The execution unit that executes the main() function and that launches
159 An mbuf is a data structure used internally to carry messages (mainly
160 network packets). The name is derived from BSD stacks. To understand the
161 concepts of packet buffers or mbuf, refer to *TCP/IP Illustrated, Volume 2:
165 Modified Exclusive Shared Invalid (CPU cache coherency protocol)
168 Maximum Transfer Unit
171 Network Interface Card
174 Out Of Order (execution of instructions within the CPU pipeline)
177 Non-uniform Memory Access
180 Peripheral Connect Interface
183 An abbreviation for the physical layer of the OSI model.
186 An *mbuf* carrying a network packet.
195 Read-Copy-Update algorithm, an alternative to simple rwlocks.
201 Random Early Detection
207 Run Time Environment. Provides a fast and simple framework for fast packet
208 processing, in a lightweight environment as a Linux* application and using
209 Poll Mode Drivers (PMDs) to increase speed.
215 Any *lcore* that is not the *master lcore*.
218 A physical CPU, that includes several *cores*.
221 Service Level Agreement
224 Single Rate Three Color Marking
227 Scheduler Round Trip Delay
233 In the DPDK, the target is a combination of architecture, machine,
234 executive environment and toolchain. For example:
235 i686-native-linuxapp-gcc.
238 Transmission Control Protocol
244 Translation Lookaside Buffer
250 Two Rate Three Color Marking
259 TUN and TAP are virtual network kernel devices.
262 Virtual Local Area Network
268 Weighted Random Early Detection
