The method discussed here extends Layer 2 technologies such as 802.1d and 802.1q LAN trunking to run over transports such as Metro Ethernet.
Metro Ethernet can also utilise Link aggregation or Resilient Packet Ring where appropriate to add link redundancy and recovery in distribution networks.
The idea is to provide highly available Ethernet switched rings (commonly used in Metro Ethernet).
Metro Ethernet (Ethernet Lit Building Research Tool)
Extensions of these cross-connects to other locations using Metro Ethernet or intercity managed wavelength are available from several carriers.
In 2004, HKBN successfully built the largest Metro Ethernet network in the world.
The forum is composed of leading service providers, major incumbent local exchange carriers, network equipment vendors, and other networking companies that share an interest in Metro Ethernet.
The MEF is a combination of a technical and a marketing forum to promote the adoption of Metro Ethernet.
These technologies are in the process of being displaced by Ethernet-based connections (e.g., Metro Ethernet) in most areas.
The company also offers stuff spanning Internet, MEF-certified Metro Ethernet, WiFi, security, telephony, and video.
