Metrobility Optical Systems Awarded Patent on Remote Management for Optical Ethernet; Technology Utilizes Inter-Packet Gap between Ethernet Frames.Business Editors/High-Tech Writers MERRIMACK, N.H.--(BUSINESS WIRE)--June 15, 2004 Metrobility Optical Systems, Inc. has received a U.S. patent for its remote management over Ethernet technology that provides the ability to remotely manage an end device without an IP address or SNMP agent. Patent 6,741,566 B1 was issued on May 25, 2004. The technology utilizes a management channel embedded in the inter-packet gap (IPG IPG Implantable pulse generator, see there ) between Ethernet frames to send management information in real time across a network. The management channel is transparent to all other Ethernet equipment. The technology provides superior network security since it requires no IP address or SNMP agent. The patented technology was developed to enable remote troubleshooting and monitoring capabilities that were previously not available in Ethernet. The troubleshooting features include remote link loopback and integral power monitoring, as well as remote monitoring of RMON (Remote MONitoring) Enhancements to the management information base (MIB) structure used by the simple network management protocol (SNMP). In 1991, RMON added comprehensive network monitoring capabilities. statistics. Management features include remote 'point-and-click' bandwidth provisioning, and monitoring equipment voltage and temperatures. These features are enabled in real time and do not impact available user bandwidth. Metrobility's IPG technology is implemented on the Company's Access Line Cards (R231) and Access Optical Network Units (RA21) that are currently shipping. The devices are managed with the Company's NetBeacon Element Manager which provides the ability to test the optical link from the central office, monitor and measure the optical power of the laser, manage bandwidth in 1Mb increments, and provide real-time line and equipment monitoring and maintenance. The troubleshooting and remote management features set initially enabled by the patented management channel - as well as features included in the IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 802.3ah Ethernet in the First Mile Ethernet in the First Mile (EFM), also known as IEEE 802.3ah, is a collection of protocols specified in IEEE 802.3, defining the Ethernet in the Access networks, i.e. First/Last Mile. management draft standard (EFM/OAM) - are available with the Company's newly announced R851 E-Services Line Card. The E-Services Line Card may be managed via SNMP (Simple Network Management Protocol) A widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc. , 802.3ah, or NetBeacon. "The same capabilities found in wide area networks - remote management, reliable connectivity, access and concentration - are essential to placing Ethernet in the metro access network (MAN), stated Alex Saunders, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of Metrobility Optical Systems. "Metrobility's IPG technology enabled the development of features for operations, administration, maintenance and provisioning (OAM&P) prior to the EFM (Ethernet in the First Mile) Using Ethernet to provide connectivity from the customer to the carrier. See 802.3ah. OAM (Operations Administration Maintenance) Refers to managing and maintaining a network or network device. The P in "OAM&P" adds "provisioning" to the list, which is a telephone company term for setting up a service. draft standard." The SNMP or IEEE 802.3ah manageable R851 E-Services Line Card will be featured at SuperComm 2004, June 22-24, in Chicago at Metrobility's booth # 22601. The RA21 Optical Network Unit and R231 Access Line Card will also be featured at SCTE's Cable-Tec Expo in Orlando, June 15-18, in Orlando, FL, booth # 2016. Metrobility has shipped over 1000 units - including those configured with ITU-grid CWDM (Course WDM) An optical transmission method that is used for shorter distances than dense WDM (DWDM). Also known as "wide WDM," CWDM transmits fewer channels and uses wider spacing between the channels for distances up to 60 km. Wider spacing up to 25 nm, compared to 1. optics - using this technology to a variety of ILECs, CLECs and MSO's who are utilizing their fiber infrastructure to deploy Ethernet to businesses.
