3 OmniStream has a scalable software architecture that can be easily tailored and customized to any individual network requirement. It can be divided into 4 major layers presentation layer, big data processing layer, collection layer, and packet management layer according to the role. Presentation Layer (Performance Manger) Real-time KPI Monitoring User Traffic Monitoring (Protocol/Service App) Call Search Traffic / KPI Analysis Packet Viewer Big Data Processing Layer Big Data Platform (IRIS) Job Controller IIRS Analyzer Memory-based Real-time Data Processing Summary Engine for Monitoring & Analysis Distributed DB Collection Layer Metadata Creation & Loading Pre-processing xdr Collection & Integration Packet Management Layer Packet Capture Packet Analysis Correlation xdr Creation User Signal VoLTE RCS Packet Management Layer Enterprise IT Network 3G/LTE OmniStream Software Architecture Diagram Presentation Layer End-to-end network performance monitoring based on the performance alarm User-based traffic monitoring Call Search and packet viewer In-depth analysis of network performance Traffic trend analysis per application, host, phone type and network equipment Big Data Processing Layer (IRIS) Memory-based data processing for real-time monitoring Data summary based on equipment, call type and application service for performance monitoring and traffic analysis Distributed database Collection Layer xdr collection from each Packet Data integration by mapping with configuration data (e.g. subscriber information, application name, etc.) Metadata creation through pre-processing and loading metadata to IRIS Packet Management Layer Applying the switch mirror and TAP to capture network packets (e.g. user data packet, signaling packet,volte packet and RCS (Rich Communication Services) packet) Processing the end-to-end information by correlating the signal and the user data packet Standard xdr creation

4 Reliable Packet Capture In major section of mobile, wired and wireless IP broadband networks which provides over 10Gbps data transaction speed, OmniStream captures the control data and user data packet without packet loss by probe devices and stores the captured packet on the disk in real-time for the preprocessing such as correlation, creating standard xdr, creating KPI summary, and etc. Standard xdr and KPI Summary Creation OmniStream creates standard xdr to monitor and analyze each user, network session, application, network equipment, or zone in real-time based on the real-time packet data collected by packet collectors probe devices, and automatically create and save the major KPI (Key Performance Indicator) summary every 5min. / hourly / daily / weekly / monthly. High-speed Big Data Processing Mobigen has successfully developed a high-speed big data processing database, Iris, through integrating the distributed processing technology for past 10 years. Iris has been applied to the commercial networks and proven its reliability by the service carriers. OmniStream is combined with Mobigen Iris in order to complete massive data (e.g., over 30 billion data records (approx. 2TB)/day) that has been collected from the network or has been processed in real-time. Most Comprehensive Monitoring OmniStream enables you to monitor and analyze the entire network traffic and service quality on a single-view in real-time by updating the traffic trends and service quality of each network element, application, and zone according to the network environment. With OmniStream, you can monitor the service quality of VoLTE, one of the major functions of LTE service environment. You can also monitor the attempts of call origination/termination, call drop, activated session, SIP register/subscribe status. In the meantime, OmniStream provides major QoS information such as packet loss, Jitter, MOS, and others. OmniStream provides performance alarm function to notice operators when a specific KPI exceeded its threshold. Operators can define major KPI traffic usage, failures, response time, etc. and set up the threshold for each KPI by level in advance. Once the operators are noticed, they can check the issue on the singleview monitor at a glance. Using OmniStream s most user-friendly GUI, you can find root causes and troubleshoot the problems quickly with easy, single-click drill down into the traffic congestion and quality degradation status from the entire network level to the zone, network session, network equipment, and major application levels. Sophisticated Analysis OmniStream continuously detects different types of traffics generated by heavy applications and heavy users in order to effectively operate the network. OmniStream offers sophisticated analysis of various traffics and qualities: Analysis of traffic pattern and service quality Analysis of subscriber call pattern Analysis of Top-N traffic and service quality Traffic trends analysis of application / host / URL / phone type / equipment OmniStream also offers packet viewer function: Displaying collected packet raw data Protocol decoding at L7 layer service, TCP/UDP decoding at L4 layer, IP decoding at L3 layer, and et With the OmniStream, operator can search data call and service usage, application usage, and service quality of a user by simply entering the IMSI (International Mobile Subscriber Identity) number in the search window.
