JDSU Expands Carrier Ethernet Field Test Portfolio
JDSU released a new set of Ethernet OAM capabilities that enable technicians to verify Ethernet OAM features in a Carrier Ethernet network. Available for the JDSU T-BERD/MTS 6000A Multi Services Application Module (MSAM), T-BERD/MTS-8000 Transport Module, and HST-3000 Ethernet Service Interface Module (SIM), the new capabilities help carriers meet end-to-end service level agreements (SLAs) and deliver differentiated Ethernet services.
The new features include the addition of link layer OAM (IEEE 802.3ah, Ethernet first mile) and the service layer OAM (IEEE 802.1ag and ITU-T Y.1731) test features. JDSU Ethernet OAM features perform end-to-end testing including verification of connectivity check messages, Ethernet loopback and insertion/receipt of Ethernet AIS/RDI alarming. This helps technicians install and troubleshoot Carrier Ethernet circuits. http://www.jdsu.com

You just read about JDSU. One of the companies whose work it now carries:
Network Instruments built Network and application performance monitoring. What became of it?
Network Instruments brought Network and application performance monitoring to Networking. That work was distinctive enough to lead to its acquisition by JDSU for US$200M. The standalone name now passes into the archive — but the team and technology continue inside JDSU today. One of 430 names here whose work outlived the company.
You just read about Ethernet. Here is what it replaced:
Token Ring (802.5) served 1985–2000. What ultimately replaced it?
Token Ring (802.5) stations passed a small 'token' frame around a logical ring; only the token-holder could transmit, giving deterministic, collision-free access at the cost of ring-management overhead. Its job passed to Ethernet — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
