Multi-link Frame Relay Emulator


GAITHERSBURG, Md., Oct. 04, 2019 (GLOBE NEWSWIRE) -- GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding the latest Multi-Link Frame Relay Emulation (MFR) software based on client-server architecture.

The MFR Emulator software acts as a Frame Relay (FR)-MFR-Data Terminal Equipment (DTE)/Router and generates traffic in compliance with frame relay fragmentation & reassembly models i.e. UNI (DTE-DCE) NNI (DCE peers) & end-to-end fragmentation over multiple virtual circuits.

“Frame Relay (FR) and MFR can be emulated using GL’s Multi-Link Frame Relay Emulator and analyzed using Multi-Link Frame Relay Analysis software. This works with GL’s T1/E1 Analysis hardware platforms (Dual Express (PCIe) T1 E1 Boards, Universal HD T1/E1 Card, USB T1/E1 unit, or tProbe™ T1/E1 unit),” said Vijay Kulkarni, CEO of GL communications.



He further added, “GL’s flexible and versatile Multi-Link Frame Relay Emulator allows traffic generation and verification over FR links and MFR bundles for end to end testing of the frame relay network. The emulator can act as a DTE device and generate test traffic across the frame relay network for checking link quality at various layers of OSI model using Bit Error Rate Testing (BERT). Also, it can act as a DTE router to route or bridge Ethernet traffic over the frame relay links.”

In addition, “GL's Frame Relay Protocol Analyzer is used to analyze and decode frames conforming to Q.921, Q.922, LAPF, Frame Relay Forum standard - FRF.9 and FRF.12, Multiple Protocol Encapsulation, LCP RFC1661, Q.933 SVC and LMI SNAP, PPP, IP, SMTP, POP3 and so on.”


Important Features of MFR Emulator

FR Simulation

Multiple FR links of bandwidths varying from 64Kbps to n*64Kpbs or sub channels can be simulated. Each FR link can be configured with multiple full duplex virtual channels (VC), and each VC is identified by a unique DLCI value. Links can be configured with parameters like fragmentation (adhering to FRF.12 standard), flags between frames, and impairments for simulating real-time network scenarios.

MFR Simulation

Multiple FR links are aggregated to create an MFR bundle with a larger bandwidth pipe. The FR links in a bundle can vary in multiples of 64 Kbps. The emulator creates multiple such MFR bundles. A bundle can be configured with multiple full duplex VC.

Traffic Simulation and Impairments

MFR Emulator supports various types of traffic that enables the user to simulate a FR/MFR DTE or a router.

As a DTE, it can be used to generate a known traffic pattern (user defined hex data, binary file data, BERT) over the virtual circuits. Another MFR Emulator on the other side of the network can verify the received traffic pattern and generate various frame level statistics.

As a router, it can route/bridge the Ethernet traffic across the onboard network interface card and the frame relay network. Also, one can simulate multiple bridged/routed IP traffic streams over frame relay links.

One can intentionally inject errored traffic into the network to simulate real time network scenarios. The user can impair traffic at bit, byte, fragment and frame level to simulate duplicated, inserted, or dropped frames, and can generate frames with CRC and frame errors.
