The Versatile Service Module (VSM) is a module that allows operators to internally connect a VPLS or VLL service into an IES or IP-VPN service. Each module is capable of 10 Gb/s throughput.
A VSM, like an MDA, is installed and provisioned as a pluggable module in an IOM.
See the SR OS R21.x.Rx Software Release Notes for a list of platforms that support the VSM.
See Versatile Service Module for more details.
