-The deployment of the BBN GENI ePC was captured to provide an outline of the required installation, configuration and run-time requirements for an ePC/eNobeB setup on a GENI resource.  See the '''[http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment OpenAirInterface ePC GENI Site Deployment]''' page for a detailed look at steps required to add ePC/eNobeB  resources to the GENI LTE multi-point VLAN and enabling the ability to share your site ePC/eNobeB setup with other GENI sites.

-__Note:__ For GENI deployments it is strongly suggested that a dedicate bare metal node be reserved.  Testing on VM has consistently shown that VM are not a viable selection for running the OAI ePC software.

-== Preliminary  ePC Installation Guidelines ==
+Instructions below highlight guidelines for installing the OAI ePC on a GENI resource. See the  [http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment OpenAirInterface ePC GENI Site Deployment] page for detailed instructions. 
 
-Instructions below were initially provided as a guide to installing the OAI ePC, for latest verified approach to using GENI ePC see the  [http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment OpenAirInterface ePC GENI Site Deployment] page. 
+==== ePC Host Configuration ====
 
-==== Machine/VM Configuration ====
-The !OpenAirInterface ePC should operate on a bare metal PC, VM, or container. Restrictions are due to kernel support, not timing.
+For GENI deployments it is strongly suggested that a dedicate bare metal node be reserved.  Testing on VM has consistently shown that VM are not a viable selection for running the OAI ePC software in GENI. See the [http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment#GetGENIResource Get GENI Resource] instructions to request a raw pc for your installation.  A reference request RSpec [https://raw.githubusercontent.com/GENI-NSF/geni-support/master/wireless/lte-raw-pc-default-image.rspec lte-raw-pc-default-image.rspec] is provided as an example, which must be edit to your your Site specific information.

 ===== Operating system =====
-Testing has been done on Ubuntu 14.04 64 bit and Ubuntu 16.04. However, OAI ePC requires the GTP tunnel module which is available from kernel > 4.8. You can obtain this via the ubuntu HWE kernels.

-On GENI xen vm depending on the configuration of the hypervisor, the guest OS may not be able to select a different kernel from that used for provisioning. The reference image was built on a bare-metal pc, and then migrated to a VM successfully.

+Testing has been done on Ubuntu 14.04 64 bit and Ubuntu 16.04. However, OAI ePC requires the GTP tunnel module which is available for Linux kernel 4.8 and higher. On GENI a kernel 4.8 must be specifically requested, as it is not part of the default upgrade path.  See the [http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment#InstaGENISiteSoftwareInstallation Installing 4.8 Kernel on InstaGENI ePC Resource] instruction for details.

+===== Installing OAI ePC Software =====
+The page [https://gitlab.eurecom.fr/oai/openairinterface5g/wikis/AutoBuild Building OAI Executables] provides instructions for building the building the OAI eNB and ePC software.  Instruction followed at the BBN for the building the ePC are captured in the [http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment#InstallingOAIePCSoftware  Installing OAI ePC Software] section. Note, the '''develop''' branch was used in the effort.
 
 ===== Configuration =====
+
+Configuration changes must be made to the following ePC files:
+        * openair-cn/etc/acl.conf
+        * openair-cn/etc/hss.conf
+        * openair-cn/etc/hss_fd.conf
+        * openair-cn/etc/mme.conf
+        * openair-cn/etc/mme_fd.conf
+        * openair-cn/etc/spgw.conf
+
+Numerous changes are required to make the installation specific to your site, a "git diff" of the configuration used at BBN can be found in the http://groups.geni.net/geni/wiki/GENILTE/LTEDeployment#ePCConfiguration ePC Configuration] section.  Also highlighted below are the required changes:
