As LMR networks move to packet-based ethernet transport, monitoring performance and outages become more complex. The combination of QOS requirements, MPLS-based architectures, and redundancy requirements introduce challenges that were not present in TDM-based transports. Standard network monitoring tools provided by leading backhaul monitoring Parsons and network management systems (NMS) carry a lot of functionality to manage large enterprise networks. These systems provide a number of tools that can be configured to give insight into a LMR backhaul network but are expensive to purchase, install and maintain. Off the shelf NMS are large versatile toolkits to solve a lot of problems. What is needed is an LMRfocused light weight management system that targets the factors that are vital to the operation of LMR networks without the baggage of tools that are not required or desired in LMR Networks. LMR networks are typically architected using MPLS as a transport technology. These networks are optimized to provide low latency and zero packet drops and need to be able to recover from failure in less than 400 milliseconds. The specifications of LMR networks are driven by the requirements of LMR equipment and the mission of the system. This solution will address the need to support the Multi-Protocol Label Switching (MPLS) Internet Protocol (IP) Ethernet networks, critical applications transport, as well as in infrastructure and services for applications and equipment used by Public Safety networks. NMS will provide a 24 x 7 continuous monitoring, portal and support of Pierce County backhaul network with immediate, prioritized response so you receive the right action plan whether it’s ‘keep monitoring for further developments’, remote restoration, or event escalation. The NMS web portal will provide real-time data that is actionable by Pierce County.
