VPLS Versus VPWS What are the differences?

VPWS

VPWS is an L2VPN technology that transmits Layer 2 services by simulating the basic behaviors and features of services, such as ATM, Ethernet, low-speed time division multiplexing (TDM) circuits, and synchronous optical network (SONET)/synchronous digital hierarchy (SDH) on a packet switched network (PSN). VPWS emulates the traditional leased line on an IP network and provides asymmetric and low-cost digital data network (DDN) services. For users at both ends of a VPWS connection, the connection is similar to the traditional leased line. VPWS functions as a point-to-point virtual private wire technology that can support almost all the link layer protocols.

VPLS

The virtual private LAN service (VPLS) is an MPLS-based Ethernet point-to-multipoint (P2MP) L2VPN service provided over a public network. VPLS ensures that geographically isolated user sites can communicate over MANs and WANs as if they were on the same LAN. VPLS is also called transparent LAN service (TLS).

The most different is that VPWS used on point to point (P2P), the VPLS used on point to multi point (P2MP)

Does it means that VPWS is used for spoke and spoke architecture whike the VPLS is used for Hub to spoke ?

VPWS is used for point-to-point connections. This approach can be applicable to your spoke-to-spoke connectivity. There is no MAC address learning, as it is PtP service.
VPLS is by default full-mesh topology, this service emulates ethernet switch and requires MAC address learning to make forwarding decisions. Can be tuned also to hub-n-spoke topology.
