Purpose-Built for Testing LTE, IMS and VoIP Networks
High data rates and quality of service (QoS) are some of the key attributes of the 3GPP specifications for LTE. Dedicated bearers, guaranteed bit rates (GBRs), maximum bit rates (MBRs) and traffic flow templates (TFTs) are some of the parameters and features that LTE networks need to support in order to ensure that the highest QoS is delivered by the network.
QoS is also a major concern in IMS networks, especially when supporting VoLTE services. In the VoLTE deployment scenario, both the IMS and LTE networks must provide the highest levels of QoS to guarantee acceptable levels of end-to-end QoS.
The W2CM-10GbE is purpose-built to simulate real-world network traffic and characterize the QoS of both LTE and IMS networks under various traffic profiles. For example, the data-profiling feature enables users to specify traffic profiles consisting of the following characteristics: dedicated, default, GBR and non-GBR bearers, mix of data types (e.g., 40% video, 30% http and 30% audio) and the average number of bearers per UE.
This unique capability enables NSPs and NEMs to test their networks against real-world traffic patterns in a controlled environment.
SmartReplay Mechanism—Testing for Today’s and Tomorrow’s Services
LTE, IMS and VoIP networks will need to provide very-high-quality customer experience when delivering services such as voice, video, data, social media, presence and rich communication services (RCS).
In addition to supporting the well known services and protocols (e.g., SIP, HTTP, RTP, FTP, SMTP and RTSP), the W2CM-10GbE, with its SmartReplay technology, can generate and analyze many other applications in real time.
The SmartReplay technology uses custom-designed FPGAs to guarantee line rate and real-time generation and analysis of stateful traffic across millions of subscribers. It provides a powerful, flexible, yet very easy-to-use GUI to facilitate the creation of new services or the modification of existing services.
In addition, users of the SmartReplay technology can easily, import, modify and regenerate any user-plane traffic.
