Metrobility Gains Patent for Inter-Packet Gap Ethernet Mgt.

Metrobility Optical Systems was awarded 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. The technology utilizes a management channel embedded in the inter-packet gap (IPG) between Ethernet frames to send management information in real time across a network. The management channel is transparent to all other Ethernet equipment.



Metrobility said 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 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. The company is currently shipping products with these features, as well as features included in the IEEE802.3ah Ethernet in the First Mile management draft standard (EFM/OAM). http://www.metrobility.com
