Luminous E200: Enlightened Transport for Ethernet

Luminous Networks enters the enterprise market with one of the first platforms based on Resilient Packet Ring, or RPR, a proposed IEEE standard.

Luminous sent me the E200 along with two of its C-Series units so I could create a ringed network. I connected one Gigabit Ethernet transmit-receive pair to each of the C-Series units and connected the C-Series devices to each other. The IP address of each device must be configured via the command line from the RS-232 port on the unit. This is routine, but to access the devices from the LMS, I had to manually create static routes--full autodiscovery hasn't made its way into the management system yet. I completed the rest of the configuration via a GUI.

Good News
  • Effectively protects Ethernet and TDM traffic.
  • Can be used in campus or MAN environments.

    Bad News

  • Management system is in early stages and it shows.
  • As with most carrier-class management systems, Luminous' LMS (Luminous Management System) has a server and a client application. Both are available for Sun Microsystems Solaris 7 or higher and Microsoft Windows NT. I tested under Windows 2000, a platform Luminous hasn't OK'd yet. The company recommends the Solaris version if your network comprises more than a few devices and four or more clients.

    LMS supports three types of users: supervisor, administrator and operator. A supervisor can perform all configuration tasks on the units and network. An administrator can only add and delete users. An operator can view configurations but can't change anything.

    Respondents are on a roll: 53% brought their private clouds from concept to production in less than one year, and 60% ­extend their clouds across multiple datacenters. But expertise is scarce, with 51% saying acquiring skilled employees is a roadblock.
