ADVANTAGES OF MPLS-TP OVER SDH TRANSMISSION

Dear friend!
When we configuring EVPL services on an SDH network, the MPLS technology can be used to isolate services to achieve bandwidth sharing. In this way, the utilization efficiency of a physical channel can be effectively improved.
Thank you!

MPLS-TP and SDH is totally different technology; first one works for IP layer and 2nd one works for TDMlayer

Multiprotocol Label Switching Transport Profile (MPLS-TP): packet switching technology
synchronous digital hierarchy (SDH) : circuit switchinng technology -works at VC level like VC12, VC4- used for service like STM1-STM4-STM16-STM64.

MPLS-TP: it is an extension of Multiprotocol Label Switching (MPLS), the protocol that allows most packets to be forwarded at the Layer 2 (switching) level rather than at the Layer 3 (routing) level.

SDH: is a new standard for multiplexing together many low rate digital traffic channels into higher rate channels in order that these low rate channels may be more efficiently transported around a telecommunications network.

MPLS-TP: It uses Generalized MPLS (GMPLS) to provide deterministic and connection oriented behavior using LSPs (Label Switched Paths), making it a dependable transport protocol.

SDH: One of the key hardware elements of SDH was the add-drop multiplexer, able to efficiently extract, from a high speed signal, a low speed service. The sub 50msec protection switching of SDH still ‘haunts’ transmission systems

Hello,

Tomorrow's network will mostly carry packets. As a result, an evolution of existing time-division multiplexing (TDM)-based transport networks is taking place, and new architectures optimized to carry packets are being defined. The function of a transport network is to carry information between service edge devices. These devices could be Digital Subscriber Line Access Multiplexers (DSLAMs), gateways, T1/E1 aggregators, broadband remote access servers (BRAS), etc. Traditional transport systems based on SDH/SONET platforms provide low-speed bandwidth granularity network services as well as high-speed long-haul transmission services. Circuit-switched transport network services with fixed bandwidth granularity (64 Kbps, 1.5 Mbps, 2 Mbps, 50 Mbps, 150 Mbps, 600 Mbps, etc.) were emulated using connection-oriented, packet-switched (CO-PS) technologies and similar managed-bandwidth services. However, in the access/aggregation and metro domains, there is a desire by carriers to simplify packet transport networking in order to reduce capital expenditures (CapEx) and operational expenses (OpEx) in their next-generation networks.

MPLS is considered a leading connection-oriented packet transport networking technology. Recently many carriers have shown their desire to converge their next-generation core networks onto MPLS, and subsequently have deployed their core networks using MPLS. Given the deployment of MPLS networks and the desire to align packet networking with more traditional transport operations methods, this standardized approach is known as MPLS Transport Profile (MPLS-TP) in the IETF (groups - MPLS, PWE3, and CCAMP) and the ITU-T SG15.

In addition to offering traditional transport operational models for packet networking, there is a requirement to interconnect the MPLS-based client customer network to the server operator network using MPLS in order to provide simple managed-bandwidth services. In this case, the customer network and the operator network are managed as independent entities (that is customer and operator), so that they can be decoupled functionally and operationally to maintain the client-server relationship.

The MPLS-TP proposal contains a set of compatible technology enhancements to existing MPLS standards to extend the definition of MPLS to include support for traditional transport operational models. This proposal adopts all of the supporting quality of service (QoS) and other mechanisms already defined within the standards, but also brings the benefits of path-based, in-band Operations, Administration, and Maintenance (OAM) protection mechanisms found in traditional transport technologies.

Hope it can help you.

Thanks!
