A network management system for point-to-point networks
Wireless point-to-point networks are being used to replace fixed wireline networks. Compared to the traditional optical cabling approach, these wireless networks can be installed and made operational in a fraction of the time and at a fraction of the cost. They are used in wide variety of situations such as to backhaul mobile networks, backhauling data to control centers, and creating private wireless networks for educational institutions as well as hospitals. These networks also serve as the backhauling systems for carrying utility data to head-end and for backhauling network traffic in wireless internet service provider networks. Most wireless point-to-point vendors offer equipment operating at several frequencies over both TDM and FDM technologies. In cases where the distance between end-points cannot be covered by a single point-to-point link, operators add a chain of several point-to-point links. The network management system for managing wireless point-to-point networks should be capable of solving the problems outlined below.
Challenges with managing point-to-point wireless networks
Reachability issues and seasonal interruptions
Most point-to-point wireless device manufacturers have a big product portfolio to cover different requirements such as bandwidth, distance, and modulation. Debugging problems in these radios are difficult since they are typically mounted over poles in remote areas. Since the links are wireless, they face seasonal interruptions such as heavy winds and snowfall.
Adaptive modulation rate supported devices
Modern devices support adaptive modulation modes. That is if they detect bad weather they can automatically reduce modulation - a good compromise between link existence and bandwidth.
Expensive truck roll-outs for network upgrades
Upgrades and configuration changes on these networks have to be done carefully in a far-end to near-end order. Changing the settings of the near-end radio leads to expensive truck roll-outs to fix the issues at the far-end. The problem is further complicated if such changes have to be done over a chain of point-to-point links.
Operator training costs
Point-to-point links also need proper configuration when used in active-standby mode and capacity aggregation modes. Training operators on all these actions will be an involved process while implementing auto-discovery of such modes within the radios will likely increase costs.
Dhyan's solution for managing wireless point-to-point networks
NetMan's wireless point-to-point solutions are being used by network operators to proactively manage their point-to-point links. NetMan's architecture and its ability to manage the dynamism of links has been the key reason for this solution's success across several point-to-point link providers. NetMan's ability to understand and differentiate wireless mesh and point-to-point solutions is crucial and a distinctive advantage. This ability has served as a key enabler for point-to-point device manufacturers planning to enter the point-to-multipoint segment.
