You can find useful purposes in the first paragraph of pwe3's charter:

	Network transport service providers and their users are
	seeking to rationalize their networks by migrating their
	existing services and platforms onto IP or MPLS enabled
	IP packet switched networks (PSN). This migration requires
	communications services that can emulate the essential
	properties of traditional communications links over a PSN.

Thanks,
