RESINetwork & Service Monitoring

The complete solutions for passive and active monitoring of communication networks and services such as 2G, 3G, 4G, ims, voip and 5G


An offer of increasingly complex and innovative commercial services.

In the current technological framework, with the constant amount of data transferred, an efficient Network Monitoring service is crucial for all those enterprises who base their reputation on the reliability of their networks.

In order to response to these new needs, an increasingly complex and innovative range of commercial services is presented.

The aim of telephone operators, ISPs and broadcasters is to enable users to access and use all the communication, messaging, information and entertainment services.

The huge variety of Network Monitoring services on the market has often led to the proliferation of a great number of management and troubleshooting tools that are frequently poorly integrated.


GEMINI™ is an integrated, modular and scalable solution for managing all your network activities and service-related issues that can optimize data traffic.

The growing need is therefore to have a single multi-service solution that manages and analyzes the behavior of the networks and services throughout their lifecycle, securing high QoS (Quality of Service) standards.

GEMINI™ platform is the technology RESI proposes for the active and passive networks and communication monitoring services available for old and new generation networks. GEMINI™ is the result of a long-lasting experience, improved in vast and complex contexts such as infrastructure of primary telecommunications operators and national and international ISPs.



GEMINI-NET™ analyzes the traffic on the network by identifying different applications and protocols used.

GEMINI-NET™ has a powerful traffic classification engine that can appropriately identify thousands of protocols used by the applications.

Through a user-friendly dashboard, this information can be used to:

  • Determine which applications affect network the most in terms of total traffic volume or bandwidth usage
  • Verify the overall traffic trend on a real-time basis
  • Identify the most critical links and prevent any inadequate bandwidth
  • Provide indicators such as Round Trip Delay, lost packages, crossing time, network congestion states and much more.


Usage allow you to fully understand the type of usage that users or groups of users make of the network.

The information acquired allow to understand customers' behaviours and to forecast future network evolutions, in order to propose new commercial offers.

Examples of reports that can be calculated are:

  • Number of simultaneous users deployed over time (hour by hour) that carried out traffic from or to specific directions
  • Bandwidth occupied by P2P traffic for users of a particular type of contract (eg. flat)


Even the most protected systems are subject to malfunctions in security devices, unauthorized accesses, and attempted attacks. To understand what occurred and decide which countermeasures to adopt, a "post-event" analysis is indispensable, enabling companies to have a clear sight of the event.

Network forensic is the discipline that deals with the reconstruction of events by using systems that can record activities on the network on different devices by correlating different information to generate alerts. Tracking activities performed on the network by users, transactions to and from certain systems etc. is generally called auditing.

GEMINI™ field of applications for auditing purposes are:

  • Legal purposes (reconstruct all the activities of a particular user)
  • To ensure the confidentiality of sensitive data (verify that the access to sensitive data has only occurred by authorized entities).


Performance Management activities during the delivery of a service are essential to guarantee customers with a certain level of quality of the service. Always more often users complain of slowness or inability to use. The possible causes of these problems are many and most of the times difficult to detect:

  • Overloading or unavailability of servers that deliver the service (server or application dependent)
  • Excessive traffic on one of the network tracts between the client and the server (network dependent)
  • Insufficient or excessively slow computers (client dependent)

GEMINI-NET™, through the extraction of a set of metrics, is able to highlights immediately the causes of slowdowns, allowing operators to quickly solve the issue and ensure a quick return to the optimal levels of QoS.

GEMINI-NET™ metrics are calculated at levels 3, 4, and 7 of the ISO/OSI stack through a completely passive approach, without using simulators or agents to be installed on the user's computer.



Quick troubleshooting tasks are essential if networks or applications are slowed down. 

In case of slowdown of networks or applications, it is necessary to identify the causes of the problems immediately activating troubleshooting tools.

GEMINI-NET™ has a wide range of tools that allows to the user an easy troubleshooting of these problems.



Quality of service Management (QoS) is the main tool through which the service provider can verify if the service works properly for specific users or class of users. Quality of Service Management is typically carried out by identifying key performance indicators (KPIs). The indicators provide a quantitative measure of the quality of the service, monitoring the adherence to the intervals considered acceptable and, if necessary, alerting the operators.

GEMINI-NET™ has a large number of predefined KPIs for basic services and allows the operator to define independently new custom KPIs.

Examples of predefined indicators are the MOS assigned to each VoIP call or the MDI for streaming video streaming service.

The creation of a new KPI by the operator can be done through simple math operators (sum, multiplication, minimum, maximum, average, etc.) applied to the information contained in the CDR/IPDR tags.



o determine the delivery level of a service, it is necessary to analyze:

  • Availability of the service, expressed as percentage of usable time by the users
  • The service performance measured through quality indicators

Either information are fundamental since, for example, a service might be active, but qualitatively inadequate or vice versa performance might be acceptable but with an unavailability period.

Service Level Management (SLM) combines the elements mentioned above with the time factor. The level of a service is measured as a percentage of the number of occurrences where the availability or performance of the service falls within certain ranges of values.

GEMINI-NET™ provides the operator with several service level management features. For each KPI the operator can define service ranges associated with the service level. The system also defines thresholds for service levels to alert the operator of cases where the level drops below certain quality standards.
