-Memory Manager (librte_malloc)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ Core Components Architecture
-The librte_malloc library provides an API to allocate memory from the memzones created from the hugepages instead of the heap.
-This helps when allocating large numbers of items that may become susceptible to TLB misses
-when using typical 4k heap pages in the Linux user space environment.
-
-This memory allocator is fully described in :ref:`Malloc Library <Malloc_Library>`.
Ring Manager (librte_ring)
~~~~~~~~~~~~~~~~~~~~~~~~~~
The librte_net library is a collection of IP protocol definitions and convenience macros.
It is based on code from the FreeBSD* IP stack and contains protocol numbers (for use in IP headers),
IP-related macros, IPv4/IPv6 header structures and TCP, UDP and SCTP header structures.
