+RIB Library
+===========
+
+The Routing Information Base (RIB) library provides a data store for routing information.
+This library is intended for use in control or management plane applications.
+There are more suitable libraries for use in data plane applications such as
+:ref:`LPM <LPM_Library>` or FIB.
+
+
+Implementation details
+----------------------
+
+RIB implements a key-value store for routing information.
+
+Routing information is represented by a prefix (key) and a next hop ID (value).
+The prefix type depends on the address family. IPv4 addresses are represented by
+``uint32_t`` values. IPv6 addresses are represented as ``uint8_t[16]`` values.
+Next hop IDs are represented by ``uint64_t`` values.
+
+.. note::
+
+ The API and implementation are very similar for IPv4's ``rib`` library and IPv6's ``rib6``
+ library, therefore only the ``rib`` library will be discussed here.
+ Everything within this document except for the size of the prefixes is applicable to the
+ ``rib6`` library.
+
+Internally RIB is represented as a binary tree as shown in :numref:`figure_rib_internals`:
+
+.. _figure_rib_internals:
+
+.. figure:: img/rib_internals.*
+
+ RIB internals overview
+
+The binary tree consists of two types of nodes:
+
+* Actual Routes.
+
+* Intermediate Nodes which are used internally to preserve the binary tree structure.
+
+
+RIB API Overview
+----------------
+
+RIB has two configuration parameters:
+
+* The maximum number of nodes.
+
+* The size of the extension block within each node. This space is used to store
+ additional user defined data.
+
+The main methods within the ``rib`` library are:
+
+* ``rte_rib_insert()``: Add new routes.
+
+* ``rte_rib_remove()``: Delete an existing route.
+
+* ``rte_rib_lookup()``: Lookup an IP in the structure using longest match.
+
+* ``rte_rib_lookup_exact()``: Lookup an IP in the structure using exact match.
+
+* ``rte_rib_lookup_parent()``: Find a parent prefix within the structure.
+
+* ``rte_rib_get_nxt()``: Traverse a subtree within the structure.
+
+Given a RIB structure with the routes depicted in :numref:`figure_rib_internals`,
+here are several usage examples:
+
+* The best route for ``10.0.0.1`` can be found by calling:
+
+.. code-block:: c
+
+ struct rte_rib_node *route = rte_rib_lookup(rib, RTE_IPV4(10,0,0,1));
+
+This returns an ``rte_rib_node`` pointing to the ``10.0.0.0/29`` prefix.
+
+* To find an exact match route:
+
+.. code-block:: c
+
+ struct rte_rib_node *route = rte_rib_lookup_exact(rib, RTE_IPV4(10,0,0,128), 25);
+
+This returns an ``rte_rib_node`` pointing to the ``10.0.0.128/25`` prefix.
+
+and
+
+.. code-block:: c
+
+ struct rte_rib_node *route = rte_rib_lookup_exact(rib, RTE_IPV4(10,0,0,0), 24);
+
+This returns ``NULL`` as no exact match can be found.
+
+* To retrieve a group of routes under the common prefix ``10.0.0.0/24``
+ (yellow triangle in :numref:`figure_rib_internals`):
+
+.. code-block:: c
+
+ struct rte_rib_node *route = NULL;
+ do {
+ route = rte_rib_get_nxt(rib, RTE_IPV4(10,0,0,0), 24, route, RTE_RIB_GET_NXT_ALL);
+ } while (route != NULL)
+
+This returns 3 ``rte_rib_node`` nodes pointing to ``10.0.0.0/29``, ``10.0.0.160/27``
+and ``10.0.0.128/25``.
+
+Extensions usage example
+------------------------
+
+Extensions can be used for a wide range of tasks.
+By default, an ``rte_rib_node`` node contains only crucial information such as the prefix and
+next hop ID, but it doesn't contain protocol specific information such as
+metrics, administrative distance and other routing protocol information.
+These examples are application specific data and the user can decide what to keep
+and how it is stored within the extension memory region in each ``rte_rib_node``.
+
+It is possible to implement a prefix independent convergence using the RIB extension feature.
+If the routing daemon can provide a feasible next hop ID along with a best (active) next hop ID,
+it is possible to react to a neighbour failing relatively fast.
+Consider a RIB with a number of routes with different next hops (A and B) as
+shown in :numref:`figure_rib_pic`. Every route can have a feasible next hop
+provided by the routing daemon.
+
+.. _figure_rib_pic:
+
+.. figure:: img/rib_pic.*
+
+ RIB prefix independent convergence
+
+In case of a next hop failure, we need to replace an active failed next hop with a
+feasible next hop for every corresponding route without waiting for the routing daemon
+recalculation process to complete.
+To achieve this we can link all existing routes with the same active next hop in a linked list,
+saving the feasible next hop ID and a pointer inside the extension space of each ``rte_rib_node``.
+
+.. code-block:: c
+
+ struct my_route_ext {
+ struct rte_rib_node *next;
+ uint64_t feasible_nh;
+ };
+
+ struct rte_rib_conf conf;
+ conf.ext_sz = sizeof(struct my_route_ext);
+ rib = rte_rib_create("test", 0, &conf);
+ ...
+ /* routing daemon task */
+ struct rte_rib_node *route = rte_rib_insert(rib, RTE_IPV4(192,0,2,0), 24);
+ rte_rib_set_nh(route, active_nh_from_rd);
+ struct my_route_ext *ext = rte_rib_get_ext(route);
+ ext->feasible_nh = feasible_nh_from_rd;
+ list_insert(nh_table[active_nh_from_rd].list_head, route);
+ ...
+ /* dataplane monitoring thread */
+ /* nexthop id fail_nh fails */
+ route = NULL;
+ do {
+ route = get_next(nh_table[fail_nh].list_head, route);
+ uint32_t ip;
+ uint8_t depth;
+ rte_rib_get_ip(route, &ip);
+ rte_rib_get_depth(route, &depth);
+ ext = rte_rib_get_ext(route);
+ uint64_t new_nh = ext->feasible_nh;
+ /* do update to the dataplane, for example to the fib */
+ rte_fib_add(fib, ip, depth, new_nh);
+ /* update nexthop if necessary */
+ rte_rib_set_nh(route, new_nh);
+ } while (route != NULL);
+

+FIB Library
+===========
+
+The FIB library provides a fast Longest Prefix Match (LPM) search for 32-bit
+keys or 128-bit for IPv6. It can be used in a variety of applications,
+the most typical of which is IPv4/IPv6 forwarding.
+
+.. note::
+
+ The API and implementation are very similar for IPv4's ``fib`` library and
+ IPv6's ``fib6`` library, therefore only the ``fib`` library will be discussed here.
+ Everything within this document except for the size of the prefixes applies
+ to the ``rib6`` library.
+
+FIB API Overview
+----------------
+
+The main configuration struct contains:
+
+* Type of :ref:`dataplane algorithm <fib_dataplane_algorithms>`.
+
+* Default next hop ID.
+
+* The maximum number of routes.
+
+* Settings for the data algorithm (:ref:`will be discussed later <fib_dataplane_algorithms>`).
+
+A FIB rule consists of a prefix and an associated next hop ID. The prefix consists
+of an IPv4 network address (``uint32_t``) and the corresponding prefix length.
+The prefix serves as the key and the next hop ID as the value while doing an LPM
+search within FIB. The size of the next hop ID is variable and must be configured
+during initialization.
+
+The main methods within the ``fib`` library are:
+
+* ``rte_fib_add()``: Add a new route with a corresponding next hop ID to the
+ table or update the next hop ID if the prefix already exists in a table.
+
+* ``rte_fib_delete()``: Delete an existing route from the table.
+
+* ``rte_fib_lookup_bulk()``: Provides a bulk Longest Prefix Match (LPM) lookup function
+ for a set of IP addresses, it will return a set of corresponding next hop IDs.
+
+
+Implementation details
+----------------------
+
+Internally FIB contains the ``rte_rib`` data struct to help maintain the dataplane struct.
+The dataplane struct is opaque, so that users can add their own algorithm implementations.
+
+
+.. _fib_dataplane_algorithms:
+
+Dataplane Algorithms
+--------------------
+
+Dummy
+~~~~~
+
+This algorithm uses ``rte_rib`` as a dataplane struct. Lookups are relatively slow,
+but extra memory isn't used for the dataplane struct. This algorithm should only
+be used for testing and debugging purposes.
+
+This algorithm will be used if the ``RTE_FIB_DUMMY`` type is configured as the
+dataplane algorithm on FIB creation.
+
+
+DIR-24-8
+~~~~~~~~
+
+The current implementation of this algorithm uses a variation of the DIR-24-8
+algorithm that trades memory usage for improved LPM lookup speed.
+This algorithm allows the lookup operation to be performed using only a single
+memory read access in most cases. In the statistically rare case where the best
+match rule has a depth larger than 24, the lookup operation will require two
+memory read accesses.
+
+This algorithm will be used if the ``RTE_FIB_DIR24_8`` type is configured as the
+dataplane algorithm on FIB creation.
+
+The main FIB configuration struct stores the dataplane parameters inside ``dir24_8``
+within the ``rte_fib_conf`` and it consists of:
+
+* ``nh_sz``: The size of the entry containing the next hop ID.
+ This could be 1, 2, 4 or 8 bytes long.
+ Note that all available bits except one are used to store the actual next hop ID.
+
+* ``num_tbl8``: The number of tbl8 groups, each group consists of 256 entries
+ corresponding to the ``nh_sz`` size.
+
+The main elements of the dataplane struct for the DIR-24-8 algorithm are:
+
+* TBL24: An array with 2\ :sup:`24` entries, corresponding to the ``nh_sz`` size.
+
+* TBL8: An array of ``num_tbl8`` tbl8 groups.
+
+The lookup algorithms logic can be seen in :numref:`figure_dir_24_8_alg`:
+
+.. _figure_dir_24_8_alg:
+
+.. figure:: img/dir_24_8_alg.*
+
+ DIR-24-8 Lookup algorithm
+
+The first table ``tbl24``, is indexed using the first 24 bits of the IP address to be looked up,
+while the second table(s) ``tbl8``, is indexed using the last 8 bits of the IP address.
+This means that depending on the outcome of trying to match the IP address of an incoming packet
+to a rule stored in the tbl24 we might need to continue the lookup process in the second level.
+
+Since every entry of the tbl24 can potentially point to a tbl8,
+ideally we would have 2\ :sup:`24` tbl8s, which would be the same as having a
+single table with 2\ :sup:`32` entries. This is not feasible due to resource restrictions.
+Instead, this approach takes advantage of the fact that rules longer than 24 bits are very rare.
+By splitting the process into two different tables/levels and limiting the number of tbl8s,
+we can greatly reduce memory consumption while maintaining a very good lookup speed.
+This method generally results in one memory access per lookup.
+
+An entry in a tbl8 contains the following fields:
+
+* The next hop ID.
+
+* 1 bit indicating if the lookup should proceed inside the tbl8.
+
+Use cases
+---------
+
+The FIB library is useful for any use cases that rely on the Longest Prefix Match (LPM)
+algorithm such as IP forwarding or packet classification.
+
+More complex use cases are also possible, as it is possible to have next hop IDs
+which are 63 bits long (using ``RTE_FIB_DIR24_8_8B`` as a next hop size).
+These use cases could include storing two next hop IDs inside the 63 bits of the next hop.
+This may be useful to provide a fallback next hop ID, ASN or forwarding class
+corresponding to a given prefix without having to perform an additional lookup.

These two comments are showing as spelling errors on aspell but I think they are ok as this is technically a code comment
and nexthop often appears in the code without a space.
