+# hICN plugin for sysrepo (2019)
+
+This plugin serves as a data management agent that runs on the same host as a
+VPP instance. It provides yang models via NETCONF to allow the management of
+hicn-plugin that runs in VPP instance from out-of-box.
+
+## Software Requirement
+
+- VPP
+
+- hicn-plugin
+
+- sysrepo
+
+## hICN yang model
+
+You can install the yang model using the following bash script:
+
+EXIT_CODE=0
+command -v sysrepoctl > /dev/null
+if [ $? != 0 ]; then
+    echo "Could not find command \"sysrepoctl\"."
+     exit ${EXIT_CODE}
+else
+sysrepoctl --install --yang=path_to_hicn_yang_model
+fi
+
+hicn.yang can be found under `plugin/yang/model/hicn.yang`. It consists of two
+container nodes: *hicn-conf* and *hicn-state*. One is used to hold the
+configuration data (i.e., *hicn-conf*) and one for providing the state
+data (i.e., *hicn-state*). The *hicn-conf* has one node, *params*, which
+contains the hICN configuration parameters. Controler can configure these parameters
+through the edit-config RPC call. This node can be used to enable and to initialize
+the hicn-plugin in VPP instance. Hicn-state container is used to provide the state
+data to the controler. It consists of *state*, *strategy*, *strategies*, *route*,
+and *face-ip-params* nodes with the coresponding leaves. In hicn model variety of
+RPCs are provided to allow controler to communicate with hicn-plugin as well as
+update the state data in *hicn-state*. Here you can find the schematic view of
+the described hicn model:
+
+
+module: hicn
+  +--rw hicn-conf
+  |  +--rw params
+  |     +--rw enable_disable?          boolean
+  |     +--rw pit_max_size?            int32
+  |     +--rw cs_max_size?             int32
+  |     +--rw cs_reserved_app?         int32
+  |     +--rw pit_dflt_lifetime_sec?   float
+  |     +--rw pit_max_lifetime_sec?    float
+  |     +--rw pit_min_lifetime_sec?    float
+  +--ro hicn-state
+     +--ro states
+     |  +--ro pkts_processed?             uint64
+     |  +--ro pkts_interest_count?        uint64
+     |  +--ro pkts_data_count?            uint64
+     |  +--ro pkts_from_cache_count?      uint64
+     |  +--ro pkts_no_pit_count?          uint64
+     |  +--ro pit_expired_count?          uint64
+     |  +--ro cs_expired_count?           uint64
+     |  +--ro cs_lru_count?               uint64
+     |  +--ro pkts_drop_no_buf?           uint64
+     |  +--ro interests_aggregated?       uint64
+     |  +--ro interests_retx?             uint64
+     |  +--ro interests_hash_collision?   uint64
+     |  +--ro pit_entries_count?          uint64
+     |  +--ro cs_entries_count?           uint64
+     |  +--ro cs_entries_ntw_count?       uint64
+     +--ro strategy
+     |  +--ro description?   uint8
+     +--ro route
+     |  +--ro faceids?       uint16
+     |  +--ro strategy_id?   uint32
+     +--ro strategies
+     |  +--ro n_strategies?   uint8
+     |  +--ro strategy_id?    uint32
+     +--ro face-ip-params
+        +--ro nh_addr?   uint64
+        +--ro swif?      uint32
+        +--ro flags?     uint32
+
+
+To setup the startup configuration you can use the following script:
+
+EXIT_CODE=0
+command -v sysrepocfg > /dev/null
+if [ $? != 0 ]; then
+    echo "Could not find command \"sysrepocfg\"."
+     exit ${EXIT_CODE}
+else
+sysrepocfg -d startup -i startup.xml -f xml hicn
+fi
+
+
+*startup.xml* is placed under `plugin/yang/startup.xml`. Here you can find the content:
+
+<hicn-conf  xmlns="urn:sysrepo:hicn">
+<params>
+    <enable_disable>false</enable_disable>
+    <pit_max_size>-1</pit_max_size>
+    <cs_max_size>-1</cs_max_size>
+    <cs_reserved_app>-1</cs_reserved_app>
+    <pit_dflt_lifetime_sec>-1</pit_dflt_lifetime_sec>
+    <pit_max_lifetime_sec>-1</pit_max_lifetime_sec>
+    <pit_min_lifetime_sec>-1</pit_min_lifetime_sec>
+</params>
+</hicn-conf>
+
+As can be seen, it contains the params leaves in *hicn-conf* node which is
+used as the startup configuration when the yang model is loaded to the sysrepo.
+This configuration can be changed through the controler by subscribing which
+changes the target to the running state.
+
+hicn model provides a list of RPCs which allows controler to communicate directly
+with the hicn-plugin. This RPCs may also cause the modification in state data.
+Here you can find the list of RPCs:
+
+  rpcs:
