New Functionality Delivers Highest Reliability for Carrier Ethernet-Based Ring Topologies
November 06, 2012
ADVA Optical Networking announced today the availability of Ethernet Ring Protection Switching (ERPS) on its FSP 150 family. The ITU-T standard, also known as G.8032v2, provides sub 50 millisecond protection and recovery switching, ensuring highest reliability for ring-based Carrier Ethernet infrastructures. Fully configured to support IEEE Connectivity Fault Management (802.1ag), the FSP 150 family now features robust fast failure detection, protection and advanced multi-vendor interoperability.
“We’re continuously listening to our customers, continuously refining our products to deliver what our customers need,” said Christoph Glingener, CTO, ADVA Optical Networking. “The introduction of ERPS is a clear reflection of this. Our engineers have worked hard to ensure that our ERPS is simple to configure, robust and capable of multi-vendor interoperability. Carrier networks depend heavily on survivable ring topologies, and we have taken this functionality to the next level.”
The FSP 150 family with ERPS now enables business Ethernet and mobile backhaul service providers to aggregate subrate Gigabit Ethernet services onto Gigabit or even 10 Gigabit Ethernet protected rings using a drop-and-continue architecture. A robust quality of service mechanism operates independently on add/drop and transit traffic, guaranteeing that service level agreements are met. The FSP 150 family uses a standard protocol for multi-vendor interoperability and supports point-to-point and multipoint services.
“Carrier Ethernet has started to rapidly replace SONET/SDH technology and is conquering more and more segments of carrier infrastructure,” commented Michael Howard, co-founder and principal analyst, Infonetics Research. “I learned long ago that service providers like rings for their resiliency and lower port count advantages. As Ethernet replacements of SONET/SDH have gathered pace, operator desire for access rings have correspondingly grown. Providers will want to evaluate ADVA Optical Networking’s ERPS technology, since it is an uncomplicated and multi-vendor interoperable approach to ring protection, something that the market clearly wants.”
