MPLS-TP is expected to be a low cost L2 technology (if the limited profile to be specified is implemented in
isolation) that will provide QoS, end-to-end OAM and protection switching.
MSTP
In 2002, the IEEE introduced an evolution of RSTP: the Multiple Spanning Tree Protocol. The MSTP protocol
provides for multiple spanning tree instances, while ensuring RSTP and STP compatibility. The standard was
originally defined by IEEE 802.1s, but was later incorporated in IEEE 802.1D-2005.
MVR
Multicast VLAN Registration (MVR) is a protocol for Layer 2 (IP)-networks that enables multicast-traffic
from a source VLAN to be shared with subscriber-VLANs.
The main reason for using MVR is to save bandwidth by preventing duplicate multicast streams being sent in
the core network, instead the stream(s) are received on the MVR-VLAN and forwarded to the VLANs where
hosts have requested it/them (Wikipedia).
