Effort underway to accelerate NMCI traffic
NMCI users will see a marked improvement in the speed of network traffic as DXC completes an enterprise-wide wide area network acceleration initiative. Instead of adding additional costly hardware, this initiative optimizes network speeds by reducing bandwidth usage while also accelerating applications.
Bandwidth reduction efforts have already shown a more than 50% traffic reduction across the NMCI network.
Put another way, if NMCI was a freeway this initiative has effectively doubled the amount of available lanes while significantly reducing the number of vehicles. That reduction in traffic frees up bandwidth for mission critical applications and provides a 4X increase in network response times.
Making better use of existing bandwidth also allows the Department of the Navy defer capacity investments, freeing up funding for other investments.
Accelerating NMCI to 10G
In response to end user feedback, the Navy and DXC have a major initiative underway to significantly speed up data flow on the NMCI network. The project is expected to be completed in July 2017 and will increase overall network traffic from a 1G speed to 10G. The first phase of the project is an assessment and upgrade of existing equipment in the larger NMCI data center locations. Once that is completed, the focus will move to the smaller server farms. In addition to faster network response times, NMCI end users will also see an enhanced Voice over Internet Protocol (VoIP) and video teleconferencing (VTC) experience.
NMCI virtual private networks get speed boost
In an effort to provide a better end user experience without compromising security, DXC recently completed an upgrade of the VPN hardware on the NMCI network. A VPN, or virtual private network, is a method used to add security and privacy to the data NMCI users share both inside outside of the Navy’s largest network. All NMCI traffic runs through a VPN, and the hardware was identified for the upgrade when it became clear it would not support desired traffic speeds and was actually creating a network traffic roadblock.
Upgrading the hardware has sped up VPN traffic by 900%, resulting in the desired 10G speed.
The next phase of the project is to eliminate the VPNs completely. Technology advancements have allowed existing outer routers to virtually assume the VPN function. This will decrease the technology footprint and allow for the transfer of functionality to another existing system without loss of security controls, all while still maintaining network speed.
Benefits at a glance:
- • 25 terabyte reduction in NMCI network traffic
- • 51% reduction in bandwidth
- • 4X increase in end user network response time
- • Deferred capacity investments
- • 10X improvement on network speeds, resulting in faster network response times
- • Enhanced VoIP and VTC experience
- • VPN traffic increased by 900% (1G to 10G)
- • Eventual removal of VPNs and movement of functionality to outer routers
- • No change in security controls or network speed
