GL Announces ML-PPP / PPP Analysis and Emulation Software

Gaithersburg, Maryland, USA - March 12, 2007 - GL Communications Inc., announced the release of ML-PPP / PPP Analysis and Emulation software - A tool that emulates and analyzes Point-to-Point (PPP) and Multi-Link Point-to-Point (ML-PPP) protocols. Speaking to the press, Mr.Jagadish Vadalia, Senior Manager of Product Development said, "Multilink PPP (ML-PPP) and PPP allow splitting, recombining, and sequencing of packets across multiple data links into a single logical pipe or bundle. This is quite useful when you need more than one T1 or E1 line capacity but not as much as a T3 or E3. For example 5 separate T1 lines can be used as a "single pipe"". He added, "ML-PPP has wide application for access lines to Internet Service Providers (ISPs) and enterprises that need "single pipes" greater than 1 T1 or E1 but less than 28 T1s (T3) or 16 E1s (E3). ML-PPP is similar to IMA (Inverse Multiplexing over ATM), in the sense that larger bandwidth is derived by aggregating smaller physical channels".

Mr. Vadalia further added, "When a single T1 or E1 line is adequate bandwidth for an enterprise, plain old PPP is used. PPP or Point-to-Point Protocol is a link layer protocol, which encapsulates other network layer protocols such as IP. It is generally based on HDLC frame structure".

GL has provided several software applications for analyzing and emulating ML-PPP, and PPP, and the below links provide comprehensive information on ML-PPP / PPP Analysis and Emulator Software:
