NTT Communications announced the development of a basic operations, administration and maintenance (OAM) function for software-defined networking (SDN) on multiple wide area networks (WAN). The new SDN OAM functions enable end-to-end network connection quality to be visualized on multiple WAN using link trace and loopback tests.
The new technology visualizes network topology by automatically collecting connection information on physical networks configuring SDN. It enables SDN operation and maintenance personnel to remotely monitor circuits and isolate problems and test circuits more accurately by verifying network connection quality and normality of link trace in end-to-end areas, even in WAN.
Key capabilities
- Visualization of physical network topology: Visualizes the types of machines used in end-to-end networks.
- SDN connectivity test: Identifies the end-to-end segment where trouble is occurring.
- SDN link trace test: Tests for end-to-end continuity when establishing circuits or changing circuit paths.
- SDN loopback test: Tests for loopback continuity when establishing circuits or changing circuit paths.
A demonstration of various verification tests for network normality using NTT Com's SDN OAM function technology will be conducted at Okinawa Open Days 2015, which will be held at Okinawaken Shichoson Jichikaikan in Okinawa, Japan from December 14 to 18.
NTT Com said it is now working to commercialize the technology for various environments involving SDN, including big data processing, high-quality broadcasting networks, enterprise global intranets, etc..
