Testing network reliability
Network reliability tools are used by network administrators in many organizations to ensure that intranet and internet are working smoothly. They are used for interactive monitoring, configuration and control of various network infrastructures such as QoS, LANand routing (Stanford Linear Acceleration Center, 2017). The reliability tools are used in tracking the performance of devices and in traffic and flow analysis.
The tools enhance performance by ensuring that the network does not malfunction but works as intended. This is by tracking the network use and mitigating and or reporting to the administrator detected issues regarding network faults, attacks (e.g. DDoS) and misuse(Stanford Linear Acceleration Center, 2017).
One network reliability tool is Axence nVision. This tool monitors network infrastructure including Windows, networking applications, TCP/IP services, servers and URLs(Axence, 2017). Through monitoring routers and switches it ensures that the connected computers, network traffic and the interface status are working as desired. Axence nVision alerts the network administrator when a new program is installed or a remote node experiences a configuration change. The tool enables remote access of computers and monitors user activity.
Another tool is Genie-Monitoring. This is a monitoring and reliability tool that collects large-scale data and is used by telecommunication companies and service providers. Using various protocols such as telnet, SQL and SSH, it can monitor multiple parameters on hundreds of thousands nodes in very short cycles(Jilroy, undated). Genie-Monitoring uses conditions and correlation rules to perform actions that mitigate any network unreliability. Its built-in reporting system generates network and the tool can be used as a stand-alone or connect to such management platforms like Tivoli and HP BTO.
OpenNMS is an open source network management tool that can also scale to hundreds of thousands of nodes from a single instance(OpenNMS, 2017). This integrated tool manages network service availability, collects performance using such protocol as JMX and SNMP, and manages internal, external and custom events via XML/TCP interface and TL1. It also has event de-duplication and notifications through various protocols. Being open source, the tool is available for free and the developers also offer support, consultancy and training.
Challenges in applying network reliability tools
A challenge in application of network reliability tools when using cloud computing, wirelessor other topologies is locating the problem when the network is unreliable because the traffic passes through multiple locations, some not under the direct control of the network administrator(TechTarget, 2010).This challenge is compounded in very large networks with millions of nodes that cannot be handled by most of the reliability tools.
Proxies-in-the-cloud via such protocols as SaaS, IaaS and PaaS pose challenges in that they complicate analysis when mixing and matching records (TechTarget, 2010). This is exacerbated by the fact that network flows between proxies are ineffective.
Privacy is also another challenge when using modern protocols. Network administrators have to limit their activities to meet privacy regulations…………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………….. … network reliability testing ………………..
