In view of the dramatic increase in Internet data traffic, network operators began several years ago to replace their older SDH\/SONET technology with packet-based technologies such as MPLS (Multiprotocol Label Switching) or industrial Ethernet.<\/a><\/p>\n

The past: SDH\/SONET <\/h6>\n

Since SDH\/SONET has been on the retreat, no new products of this technology are coming onto the market and deliveries are mainly limited to extensions of existing networks.<\/p>\n

Therefore, a future-proof network for energy suppliers must definitely be packet-based. This is confirmed by the preparations taking place in the energy world for migration to packet-based data. For example, the IEC 61850-90-1 standard describes the application of IEC 61850, which extends a communication protocol for packet transmission within a substation to communication between substations.<\/p>\n

The future: Packet-carrying technologies<\/h6>\n

In the meantime, there are various packet-transmitting transport technologies available to replace the traditional SDH\/SONET: MPLS, Carrier Ethernet and the more recent MPLS-TP (Multiprotocol Label Switching – Transport Profile). MPLS was introduced at the beginning of the century and was positively received by many network operators. The first drafts of MPLS-TP are still quite young.<\/p>\n

MPLS-TP supports all the essential features of MPLS and also provides functions for critical, reliable data transport. This standard was jointly developed by the ITU-T (International Telecommunication Union) and the IETF (Internet Engineering Task Force). <\/p>\n

Advantages of MPLS-TP over MPLS<\/h6>\n

Deterministic behavior and improved network settings:<\/p>\n
