4 OSIX From surveillance to advanced troubleshooting With the state-of-the-art monitoring system OSIX, Polystar offers the telecom market a wide range of real-time network monitoring solutions. Using OSIX, you will be able to observe the network activity in real time, which is crucial to maintain a first-rate customer experience and prevent quality degradation. OSIX is a passive probe system that non-intrusively extracts information from the control and user planes in telecom networks. Control plane signalling is available in real time, and the data is also stored for later retrieval for historical analysis. The user plane data is correlated in real time against the corresponding control signalling. The OSIX system is used for monitoring, troubleshooting, alarming, and xdr generation. OSIX supports fixed-line, mobile, and IMS/VoIP all in one system. The OSIX system is an extremely robust solution with a small footprint is a true real-time system offers intuitive, easy-to-use applications with context-sensitive help functions offers unique scaling possibilities due to its modular design is built using Java, MySQL, and Linux, employing state-of-the-art hardware and open architectures, standards, and interfaces is highly flexible, with extremely fast installation and acceptance cycles, as well as regular implementation of new features has low investment requirements, while offering high cost-efficiency, rapid ROI (return on investment) and a very competitive TCO (total cost of ownership) The software component of OSIX includes a set of applications for viewing and analysing network data. These offer a sophisticated correlation functionality that provides an end-to-end, network-wide view of calls and data transactions. The Network Status and Statistics Alarms applications provide powerful alarm-handling functionality and allow integration to third-party systems through SNMP traps. The Mass Call, Performance Analyser, and Real Time Statistics applications provide fast and accurate error detection, allowing the operator to quickly detect and resolve network problems or poor performance before customers are affected. The OSIX system is the foundation of all Polystar network and service assurance solutions. The advanced features of this all-seeing system, in symbiosis with the power of Polystar s real-time visualisation and reporting tool Jupiter, give you full control over your network business. Features All protocols and network technologies are accommodated in a single system Handles both control plane and user plane on a number of interfaces (including E1/T1, STM-1, ATM, Gigabit and 10-Gigabit Ethernet) Generates real-time alarms for quick detection and resolution of network problems or poor performance before customers are affected Generates real-time raw xdrs for third-party integration Includes intuitive drill-down functionality for root-cause analysis

6 APPLICATIONS Protocol Analyser Protocol Analyser In Protocol Analyser, you can monitor all messages on a link down to the lowest Call Trace level, either in real time or with historical data. All protocols can be mixed in one view. You can filter the protocol data in several ways, using link, protocol or parameter Performance Analyser filters separately or in combination. Mass Call Advanced filtering functionality with an extensive set of filter options for specific nodes, messages, release codes or user identities (IMSI, MSISDN, etc.) Detailed information for each message is easily accessed Up to four Main Window sessions can be active at the same time Real Time Statistics Network Status Statistics Alarm Windows in the Protocol Analyser application are highly configurable, allowing easy adaption to personal preferences

7 Call Trace Performance Analyser The Call Trace application monitors calling processes, in real time or using historical data. It then correlates network messages into complete calls, for analysis of the entire chain of events from start to end. The application features advanced filtering functionality, and offers comprehensive tools for adapting the user interface. You also have quick access to detailed information about the processes and all messages sent during the session. The comprehensive correlation functionality allows you to view messages for all the different protocols of the end-to-end signalling flow, for example all messages involved in a mobile call, SMS transaction, or a VoIP call. Call Trace helps your support staff give first-rate service to the subscribers, thanks to the complete overview of all calling processes and root cause analysis capabilities of calling events. With Performance Analyser, you can monitor calling statistics for different groups of nodes and numbers in your network in real time. It provides real-time overview of network quality and monitors network-related KPIs, for example ASR, NER, PDP activations, per user-configured group. With flexible configuration options, you can create various call groups for real-time KPI measurements. Advanced filter tools allow you to pinpoint and monitor the exact type of information or site. Performance Analyser is commonly used on NOC walls, to provide an instant overview of the performance of configured destinations, and also among roaming departments to analyse outbound roaming. Instant drill-down access to Call Trace and Protocol Analyser for root-cause analysis SNMP support for alarm generation to other systems A call-flow view, displaying how messages are sent between different nodes, is available for both single and correlated calls Signalling technicians get access to all the bits and bytes of every calling process and protocol message for deep analysis Call Trace supports a number of protocols for fixed, mobile, IMS/VoIP, and intelligent networks Advanced filtering capabilities with extensive set of filter options for specific nodes, messages, release codes, and user identities (IMSI, MSISDN, etc.)

8 Mass Call Real Time Statistics The Mass Call application provides real-time monitoring of call attempts made to specific With the Real Time Statistics application you can set up and view statistical information in numbers, or made from specific numbers. graphs or in table format, over configured parameters, messages or calls in your network The application allows you to quickly identify if congestion scenarios are caused by mass in real time. calling events such as viewer voting in popular TV shows. Mass Call can also be used to When configuring the graphs, you can decide how often you want the graph to be updated identify fraudulent usage and to detect loop scenarios in the network. (in seconds), and for how long you wish the data to remain in the graph (in hours and When running Mass Call, you can have one window displaying high amounts of call minutes). attempts to certain numbers and one window displaying high amounts of call attempts The graphs can be of two different types: message-based or call-based. That is, each from certain numbers. graph you create can be based either on the number of protocol messages or the number Detailed information about calling/called numbers, and the concerned point codes, is easily accessed Drill-down to Call Trace and Protocol Analyser, where filters will be set auto matically based on the numbers you have chosen of calls that pass through the graph s filter settings. It is also possible to display different traffic types in the same graph. Using Real Time Statistics, you can monitor network traffic continuously, focussing on traffic to selected destinations or towards specific applications. Extensive set of filtering options for statistical counters (same as in Protocol Analyser and Call Trace), which can be used either separately or in combination Colour schemes for quick overview and problem detection Instant drill-down access to Call Trace and Protocol Analyser

9 Network Status Statistics Alarm The Network Status application is used to monitor alarms in the network on level 1 With the Statistics Alarm application you can set up alarms that are to be generated when (hardware), and on levels 2 and 3 (nodes and links), including link load. The application also certain filter criteria for protocol messages or calls/transactions are met. The alarms can receives and stores all alarms from the Performance Analyser and Mass Call applications, be generated either at first occurrence, or after a certain number of occurrences over and alarms based on configured thresholds in the Statistics Alarm application. a certain period of time. You can also configure the alarms to be automatically cleared. Detailed information about an alarm is easily accessible, regardless of in which area or at The application runs unobtrusively in the background. Triggered alarms are available as which level the alarm occurs. This will help you detect problems quickly, and decrease the SNMP traps, and are also displayed in the alarm application in Network Status. time needed for problem solving. When monitoring the network using network maps, you have quick and easy access to detailed information about the links. There is also a Global Link Status view, that displays the current global link status, with link loads, counters for messages, etc. The Active alarms and Alarm log dialog boxes allow you to see all alarms that are currently active, and perform network-wide searches for historical alarms Instant drill-down to Call Trace and Protocol Analyser for troubleshooting alarms Map view with automatic detection of SS7 links/point codes and SCTP associations/ endpoints SNMP support for alarm generation to other systems Advanced filtering functionality (same as for Call Trace/Protocol Analyser) SNMP support for alarm generation to other systems

10 One system that shows you everything you need to know.

11 The OSIX system As the network topology becomes more and more complex, requiring legacy fixed networks to coexist with modern IP-based LTE networks, disturbances in a modern telecom network can come from a number of places. Faults can occur in anything from handovers, DNS lookups, and access points to cooperation with roaming partners. Network anomalies and root-cause errors can appear at any time, and having a monitoring system like OSIX in place is essential to maintaining full control over network activity and keeping a high level of customer satisfaction. One of the main advantages of the OSIX system is that it supports all commercially used technologies in the telecom industry in one system. You do not need to run different systems to monitor your entire network. OSIX is also a future-proof system, demonstrated by the support of both legacy SS7 and state-of-the-art LTE technology in the same system. System design The OSIX system is a scalable solution that consists of probes, servers, and clients. The probes are non-intrusively connected to the network, and are independent from data collected by the switches. The system receives network data from three different types of probes, depending on the interface to be monitored: E1/T1 probe with support for E1/T1 (64/56 kbps, HSL, FR (for Gb)) Gemini probe with support for ATM/SDH (STM-1) MediaProbe with support for Ethernet (10/100 Mbps and 10 Gbps), for monitoring of signalling traffic as well as user plane data From the probe, data is sent through a router (RTR) that distributes the traffic evenly between an arbitrary number of probe servers, which enables data capture on even the largest Tier 1 installations. An OSIX deployment typically consists of multiple, regionally distributed sites, where each site has probes and servers installed to capture, process and store all data locally. This minimises the need to send data using expensive WAN bandwidth. Storage of Signals (SoS) includes all captured signalling messages, and is normally dimensioned to hold data for 4-10 days. The mapping server (MAS) performs mapping between IMSI and TMSI. The global server (GLS) acts as the OSIX management and authentication system, and the performance server (PES) is the engine behind the Mass Call and Performance Analyser applications. For hardware efficiency, and to accommodate smaller sites, several components can share the same physical hardware.

12 OSIX in Polystar s Network and Service Assurance offering Polystar offers a broad range of products in telecom network monitoring solutions. OSIX is the product closest to the network, where it gathers network data directly from the probes in real time. OSIX can then supply data to Jupiter, Polystar s reporting and OSS system. It is also the engine for the generation of xdrs to third-party systems, such as revenue assurance, fraud management, and active roaming management systems. POLYSTAR Polystar is the premier supplier of Service Assurance, Network Monitoring and Test Solutions to leading telecom operators, service providers and network equipment manufacturers around the globe. The innovative product portfolio supports the complete lifecycle of new services and technologies from design, pre-deployment verification and stress-testing, through roll-out, down to network assurance and service management of in-service mobile, fixed, IP or converged networks. Polystar is recognised as one of the fastest-growing companies in Sweden. Since its establishment in Stockholm in 1983, it has experienced a continuous and sustainable growth, and evolved to a global presence, serving its customers in over 50 countries. Facts Server hardware Polystar uses HP ProLiant servers as probe servers. The physical measurements are 1U 19''. The probe servers are configured with RAID 1+0, which prevents data loss in case of hardware failure. Operating system The probe servers are running Red Hat Enterprise Linux as operating system. Database The probe servers are using MySQL as database system. Scalability OSIX is built to be efficiently scalable from a small system into large systems. The amount of hardware needed is directly related to the amount of traffic on a single site. If one site has small traffic volume only 2 servers are needed (one probe and one PRS). The GLS (Global Server) is only needed in one central location. This makes it possible for OSIX to be a system for any operator, from a global operator to a locally based virtual operator.
