Multiprotocol Label Switching (MPLS) is a promising effort to provide the kind of traffic management and connection-oriented Quality of Service (QoS) support found in Asynchronous Transfer Mode (ATM) networks, to speed up the IP packet-forwarding process, and to retain the flexibility of an IP-based networking approach. The roots of MPLS go back to numerous efforts in the mid-1990s to combine IP and ATM technologies. The first such effort to reach the marketplace was IP switching, developed by Ipsilon. To compete with this offering, numerous other companies announced their own products, notably Cisco Systems (Tag Switching), IBM (aggregate routebased IP switching), and Cascade (IP Navigator).

MPLS and IP MPLS cannot be compared to IP as a separate entity because it works in conjunction with IP and IP's IGP routing protocols. MPLS LSPs provide dynamic, transparent virtual networks with support for traffic engineering, the ability to transport Layer-3 (IP) VPNs with overlapping address spaces, and support for Layer-2 pseudowires using Pseudowire Emulation Edge-to-Edge (PWE3) that are capable of transporting a variety of transport payloads (IPv4, IPv6, ATM, Frame Relay, etc). MPLS-capable devices are referred to as LSRs. LSR devices provide traffic engineering functions can be defined using explicit hop-by-hop configuration, dynamically routed by the Constrained Shortest Path First (CSPF) algorithm, or configured as a loose route that avoids a particular IP or that is partly explicit and partly dynamic. In a pure IP network, the shortest path to a destination is chosen even when it becomes more congested.
What is Multiprotocol Label Switching (MPLS)? - Definition from Whatis.com
What is MPLS VPN ? MPLS stands for "Multi-Protocol Label Switching" packet-switching VPN technology. After MPLS VPN is used, incoming data packets are assigned a "label" by a "label edge router (LER)". Such labeled packets are forwarded along a "label switch path (LSP)". Along a LSP, each "label switch router (LSR)" forwards a packet based solely on the instructions of the label. MPLS :: Frequently Asked Questions

Multiprotocol Label Switching Multiprotocol Label Switching ( MPLS ) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table . The labels identify virtual links ( paths ) between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols . MPLS supports a range of access technologies, including T1 / E1 , ATM, Frame Relay, and DSL . [ edit ] Introduction MPLS is a highly scalable, protocol agnostic, data-carrying mechanism.
Different between MPLS IPLC
Q&A: IPLC & MPLS MPLS is a standards-approved end-to-end circuit technology that speeds up network traffic flow and makes it easier to manage. MPLS involves setting up a specific path for a given sequence of packets, identified by a label on each packet. An IPLC (international private leased circuit) is a point-to-point private line used by an organization to communicate between geographically dispersed offices throughout the world. An IPLC can be used for Internet access, business data exchange, video-conferencing, and any other form of telecommunication. MPLS vs IPLC MPLS is called multiprotocol because it works with the Internet IP, ATM, and frame relay network protocols.
Vs MPLS/IPLC links
Hi Anand It totally depends on the service provider who offers you the respective services. AFAIK in IPLC if you are given 2 Mbps you will be given a TDM pipe on which you can run/do whatever you desire to have. In case of MPLS network it totally depends on the SP backbone network and the kinda links he owns between his location. If the SP is having enough bandwidth capacities between all his pops then you will have necessary bandwidth allocated as assured by your SP. Generally we as a SP out here give as per the contracted bandwidth to our customers... Difference between MPLS & IPLC

MSTP short for Multiple Spanning Tree Protocol is an IEEE standard was inspired by Cisco Multiple Instances Spanning Tree Protocol. In MSTP, you can create a multiple groups for different types of VLANs and then run single instance of spanning tree for a single group of VLANs. But in traditional PVST, there is a different instance of spanning tree for each VLAN. MSTP Configuration - Multiple Spanning Tree Protocol
