The Taylor building is an extension facility for the Federal Government and is connected to the DoD network. The objective of this project was to migrate the Taylor building from its ATM backbone to the Crystal City IP/MPLS MAN. Different organizations within the building were using their own network space and network policies. This project divided into 10 sub-projects.

November2006- Overseas Department of Defense Network |
|
This DoD network was created as a hub and spoke design in 2003 conforming to a standard Enterprise model. Over a three year span, important spokes became hubs but did not change their network or data flow methodology.This created a “hybrid” enterprise. This network had no datacenter solution and hosted a single server farm under a spoke for the entire enterprise. The IBGP design was not well thought out having multiple unnecessary IBGP groups with primary/secondary route reflectors in each group. The EIGRP design was over engineered using offset-lists to manipulate traffic over low bandwidth satellite communications. The applications and services using the network were in line with applications and services used on a carrier scale network and network convergence was trying to be achieved.
I developed the plan to migrate from the hybrid enterprise hub and spoke model to a carrier model capable of carrier services to meet next generation solutions already trying to be used. This plan highlighted the problems being the initial design, "patches and band aids", no scalability, bandwidth limitation, no bandwidth application guarantee, and overly complicated redundancy schemes if any at all.
The end goal was to develop a carrier grade network. To do this the plan concentrated on a new layer one core design, migration from EIGRP to ISIS, redesign IBGP into a simpler standards based solution, overlay MPLS, overlay QoS using carrier best practices, implement L3 VPNs, create VRF's per traffic type, network convergence, create IPv6 compliance, redesign the primary/secondary exit strategy out of theater, and decrease network access points to a manageable number.

October 2007- Joint IED Defeat Organization |
|
I was hired onto the JIEDDO team to analyze the network condition, propose better solutions if needed, and implement changes. The JIEDDO network spans multiple theaters via satellite communications (SATCOM). The network design was centralized per theater but had a mix of centralized and distributed server architectures for the global design. Active Directory (AD) replication between theaters and end sites was needed. Initially all sites in one theater connected back to the continent United States (CONUS) for directory and other server services. This created multiple SATCOM hops. All sites had their own private AS and peered to CONUS. There was no LAN standardization, no WAN standardization, and no future expansion capability. Due to the initial engineering, complicated route policies were used in many places to control traffic verse using the inherent capability of dynamic routing protocols. I developed a plan that addressed each area of concern and was transferable to the other theaters. | |

March 2009- Technical Analysis and Cost Estimate for Mortgage company |
|
I conducted a consultation for a mortgage corporation in Ashburn Virginia. The deliverable for this consultation was a technical analysis and cost estimate (TACE). I discovered this small business suffers from what most small businesses suffer from. As the company grows, the IT infrastructure and servers do not. By growing the IT infrastructure, this organization will see a decrease in operational and capital expenditures. This is accomplished when a business aligns technology with its business goals and allows technology to improved employee productivity. The TACE outlined deficiencies with their internet service provider, their core router, LAN switches and hubs, servers, lack of user level authentication to gain network access, network security, and remote access solution. Optimizing their network will consist of moving from the unsecured small office design to a more robust and scalable design that will enable them to make incremental changes to the network as the company grows.
