[February 07, 2005] NETCORDIA’S VOIP MODULE DEPLOYED BY JOHNS HOPKINS BLOOMBERG SCHOOL OF PUBLIC HEALTH Tweet ANNAPOLIS, MD – February 7, 2005 – Netcordia, a provider of network analysis products, today announced that Johns Hopkins Bloomberg School of Public Health has deployed its VoIP module as part of NetMRI. NetMRI for VoIP is the first automated enterprise network appliance that proactively identifies difficult to find issues that can significantly affect VoIP quality. As a leading international authority on public health, the Johns Hopkins Bloomberg School of Public Health is dedicated to protecting health and saving lives. Every day, the school works to keep millions around the world safe from illness and injury by pioneering new research, deploying its knowledge and expertise in the field, and educating tomorrow's scientists and practitioners in the global defense of human life. To help accomplish its goals, the school has put in place a state-of-the-art data network. Over the years, as the school has grown so has the network, to over 200 network devices and 3500 computers. They have had success using the NetMRI during the expansion and decided to deploy the VoIP module to go along with it. “The ability of NetMRI VoIP to identify poor call paths and then isolate the issue down to the device or system is very helpful,” said Kevin Stone, senior network administrator at the Johns Hopkins Bloomberg School of Public Health. “NetMRI-VoIP provides key useful information that we can act upon, in a manner that is intuitive and accessible. It is more than just graphs and statistics- it identifies the real issues to resolve to maintain high quality.” NetMRI’s VoIP module determines the actual quality of IP phone calls by evaluating Call Data Records (CDRs) for delay, jitter and dropped packets. It also correlates abnormalities with other contributory network events, and provides helpful detail to solve the issues. NetMRI’s VoIP module pulls CDRs from Cisco’s CallManager. The new VoIP module also provides assessment of whether the existing IP network can support VoIP. It uses Cisco’s SAA protocol, already built into most Cisco routers and switches, to create ‘synthetic transactions’ or simulated voice traffic to determine viability based upon the measured delay, jitter and dropped packet counts. This leverages the installed infrastructure, without buying or adding probes or external devices. Johns Hopkins previously deployed the NetMRI, without the VoIP module. Key features of NetMRI include its “network expert in a box” correlation engine, its Scorecard that provides easily understandable reports for both executives and network engineers, and its ease of installation and use. NetMRI’s proactive and intuitive systems-level approach provides control and significant savings in troubleshooting time and expense across an enterprise’s network infrastructure. About Netcordia Established in 2000, Netcordia develops and markets appliance-based network analysis tools. Its development team has worked on Cisco's IOS, been awarded a patent for the v-LAB network training system, and brings over 85 collective years of experience to network diagnostics and analysis.
