Fiber-optic network will be self-healing
Excavator damaged undersea Optical Fiber Cable, or an earthquake destroyed the fiber optic connector, the entire communication network may be paralyzed; but this will not happen again. Communication service providers accelerate the deployment of the mesh topology, routing data and voice between the nodes through the jump to the other node automatically reconfigure to avoid failure or overloading of the path, so that the network link to self-repair.
Wireless mesh network in the lively discussion at the moment, you may think that the optical network point-to-point or ring network, but the fact is already a far cry from the global fiber optic network has rapidly migrate to the mesh topology . The mesh network is the future trend. In the metropolitan area network level, the mesh network is progressing rapidly. Ronald Kline, said: Ultimately, the mesh network will be everywhere, from the metropolitan area network to the regional network and then on every continent, the United States Boston industry Ovum director of research and development of fiber-optic network network, intercontinental network, as well as global, and will use a mesh topology.
As intercontinental routes around the pole, that is, beyond the pole, the global network of fully connected network to allow traffic flow in the case of congestion and failure to provide nearly 100% of network availability and to ensure that failure – a secure execution mode. U.S. companies Ciena ‘, the AT & T, Verizon Business is, India’s industry by Internet 2 newbie the Tata Teleservices in, and over 30 other vendors and service supply provider, is from the old point-to-point or ring network to provide fault – a secure connection mesh network switching , Ciena will be described as “high survival (survivable). Benefit most from our mesh network topology, we construct a viable link, even if multiple failures, still functioning; Ciena ‘responsible, James Zik, senior fiber optic network adapter product marketing manager for optical transmission products introduced: we Many customers use the five-dimensional node, that is, five fiber optic connections between the nodes, rather than a ring or a simple two-way connection, so even in the event of multiple failures, the user will not lose the link.
Reticular fiber network to use a specially crafted wireless network technology, to ensure that the link; including add a new node at any time, automatically assigned their own workload to achieve the ability to optimize the use of the new routing resources. Moreover, fiber-optic network mesh topology need to deal with the mobility of wireless nodes have better survival than a wireless network. Ciena is expected to receive the largest global market share, but other equipment suppliers are chasing market share.
For example, Sycamore Networks (the device connected to Sprint’s backbone fiber optic network network), and metropolitan area mesh network supplier Alcatel-Lucent.
