GL Communications Announces Enhanced ML-PPP Analysis and Emulation Software

Gaithersburg, Maryland, USA – November 23, 2007 - GL Communications Inc., announced today the release of enhanced ML-PPP Analyzer and Emulator software – Tools that emulate and analyze Point-to-Point (PPP), Multi-Link Point-to-Point (MLPPP), and Multi-Class MLPPP protocols. Addressing the press conference, Mr.Jagadish Vadalia, Senior Manager of Product Development said, “ML-PPP has wide application for access lines to Internet Service Providers (ISPs) and enterprises that need "single pipes" greater than one T1 but less than 28 T1s. ML-PPP is similar to IMA (Inverse Multiplexing over ATM), in the sense that larger bandwidth is derived by aggregating smaller physical channels”. He added, “The Multi-Class Extension to Multi-Link PPP allows a sender to fragment the packets of various priorities into multiple classes of fragments, and allows high-priority packets to be sent between fragments of lower priorities”.

Mr. Vadalia further added, “GL's flexible and versatile applications in T1 E1 Analyzer allow complete PPP, MLPPP, & MC-MLPPP Analysis & Emulation. The T1 E1 Analyzers are available as powerful HD PCI cards as well as portable USB based units”.

MC-MLPPP using Client Server

GL’s MC-MLPPP Emulator allows traffic generation and verification over PPP links using industry standard Client-Server technology, which may be accessed through a GUI for manual testing or through command line scripts for automation.

Important Features

•Supports up to 8 T1/E1 Full or Fractional Links
•LCP with PPP, MLPPP, and Multi-class negotiation options
•Control Protocol negotiation using IPCP
•Multi-Class over MLPPP
•MC/MLPPP payload traffic generation and reception using Sequence number, HDL file (containing packets/frames), Flat Binary file, and User defined frame (ASCII HEX file) for each class independently


ML-PPP Analyzer (GUI Based)

The MLPPP Analyzer captures a host of PPP protocols exchanged between the two nodes over T1/E1 links & provides useful analysis, which includes distribution of protocols, protocol fields, frame lengths and frame status. The PPP Analyzer has the ability to decode PPP, MLPPP, and MC-MLPPP packets.
Important Features

•Ability to test and analyze HDLC based PPP protocol in synchronous environment

•A single instance of the analyzer supports reassembly and decoding of multiple MLPPP bundles simultaneously. Each MLPPP bundle is created by selecting groups of timeslots on various cards. Each group of timeslot selection can have different data rates.

•Ability to capture and decode both PPP routed protocols, PPP bridged protocols , MLPPP, and MC-MLPPP streams of data

•Ability to test and perform numerous measurements across WAN- LAN or LAN-LAN connection

•Supports various data transmission rates starting from fractional DS0 to DS1 (subchannels). Frames can be captured in either, n x 64 kbps, or n x 56 kbps data channels
