Edge switch maker Hammerhead Systems last week announced enhancements to its HSX 6000 switch, including a "multiclass"
implementation of VPLS and support for Provider Backbone Transport (PBT).
Virtual Private LAN Service is a multipoint-to-multipoint Ethernet LAN service that makes corporate offices in metro areas
or across the country appear to be connected to the same LAN. It is based on MPLS technology, which service providers have
made considerable investment in over the past decade to engineer traffic on their networks and found new VPN service offerings.
VPLS is one such recent new service.
