TravelHawk Pro improves network analysis, optimization and troubleshooting time, and is designed for three main operations: LTE end-to-end network analysis, IP application data analysis and data capturing. The capacity to support all three operations in a portable form-factor is what makes this tool so powerful. Plus, TravelHawk Pro also dramatically improves network quality and decreases the average mean time to repair (MTTR) from days to hours.
Mobile Network Signaling Analysis
TravelHawk Pro brings together line-rate capturing and live analysis capabilities, where LTE signaling is deciphered, analyzed and correlated over all interfaces. Millions of sessions can be processed in one hour. Every LTE session is isolated and all major call parameters across the LTE network are displayed. At a glance, session behavior from S1-MME interfaces (e.g., attach procedures) can be correlated with any issues in S6a (e.g., authentications) or S11 (e.g., PDP bearer modifications), and others, like X2 (e.g., handover procedures).
VoLTE is a good example of a service that requires comprehensive end-to-end support. For this reason, TravelHawk Pro
supports the full LTE control-plane signaling analysis of VoLTE sessions. It identifies the user identifications (IMSI/PSTN/IMEI), network locations (TAC/APN/etc.) and all signaling-related problems from S1-MME, S6a, S11 and other interfaces. Essentially, it ensures the very fast detection of VoLTE calls, specific users and erroneous calls.
TravelHawk Pro also offers the one-click correlation of LTE and SIP/RTP sessions as well as information over S1-U, S5/8, Sgi, etc. The user plane can be drilled down to show all the SIP/RTP-related session information, including caller ids and media types, as well as quality of service (QoS) values like mean opinion score (MOS). TravelHawk Pro will directly drill down from the sessions to the message flow and details. This view shows every session-related message from the control-plane interfaces as well as the related SIP/RTP messages for deep root-cause analysis. Finally, the Voice Playback option makes it possible to listen to phone conversation
LTE, Statistics to the Details
Network level issues from the user plane and LTE signaling interfaces can be seen in statistical views, making failed sessions easy to troubleshoot. They can even be filtered according to failure type or network element. From
any KPI level, the user can drill down to the failed sessions themselves to discover if they were caused by the same subscriber or by the mobile type, for example. A detailed network analysis of the session can be activated in
one click in the Message Sequence Chart view, providing the technician with the detailed information needed to identify the root cause.
TravelHawk Pro is the ideal tool for telecom and IT professionals requiring a high-performance, data capture and processing unit for 1 and 10 Gbit/s Ethernet networks. Data is captured in a nanosecond PCAP format, which is an open standard that any tool can use. Full line-rate packet filtering and processing is supported—for multiple 10 Gbit/s Ethernet interfaces—regardless of packet size. TravelHawk Pro offers a line-rate data-analysis capability with hardware filters and up to 20 Gbit/s sustained capturing to local storage
IP Application Data Analysis
TravelHawk Pro can post-process all-IP, transmission-level or tunneled-level (mobile IP) flows thanks to its powerful IP application analysis engines. It also displays all basic TCP/IP-level problems. The comprehensive, automatic detection and analysis of almost any application (Skype, Facebook, emails, etc.) and its details gives full visibility of the user experience at the application level. Combined with the industry’s leading LTE/EPC analysis support, TravelHawk Pro makes troubleshooting subscriber QoE easier than ever. Find subscribers in seconds using IMSI/GUTI or any other indicator, and observe the signaling experience. Plus, one click is all it takes to see the throughput of every application and other QoS values from the subscriber’s LTE packet connection.
TravelHawk Pro provides graphical views that make it easy to pinpoint network flows, sessions and conversations. All data is
displayed in different tables where flows can be filtered, grouped or sorted. With the Diagnostics Suite, users can analyze individual IP flows and obtain information such as the source and destination IP addresses, ports, protocols, locations, origins, throughput, amount of transferred data values, etc. Users can also view information such as VLAN tags, Q-in-Q, MPLS, GTP TEIDs, as well as the flow data for tunneled IP connections, which are mainly used in mobile networks like PS Core and LTE.
The diagnostics suite offers advanced QoS and KPI graphs, including charts and diagrams for per-individual statistics, traffic
distribution and throughput, as well as aggregated flows and sessions. Moreover, administrators can easily monitor bandwidth usage for specific connections. As for QoS and service level agreement (SLA) measurements, graphs are available for the most important KPIs, such as throughput and jitter. The Diagnostics Suite also enables the high-accuracy analysis of applications, ensuring their identification and classification with key parameters. Application quality measurements are also easily performed in predefined QoS analysis views (e.g., subscriber’s QoE, top websites, web traffic QoS and audio/ video analysis). For example, SIP sessions, RTP, voice and MOS are analyzed for every call.
Finally, IP application analysis supports automatic, over-the-top (OTT) detection, making troubleshooting Skype, YouTube, Facebook or other applications, easier than ever. In fact, over 1000 applications are detected with specific details provided for each.
