Verizon already has 100Gbps (gigabit-per-second) connections overits optical core networks across continents. Now the carrier isbringing that speed to its metro networks, which enterprises tapinto for high-speed data connections. The metro networks so farhave been limited to 10Gbps or 40Gbps, so that's all enterpriseshave been able to buy, according to Glenn Wellbrock, Verizon'sdirector of ptical Transport Network Architecture and Design. Though the carrier doesn't expect many customers to start ordering100Gbps connections soon, it is preparing for the future, Wellbrocksaid. For example, many large organizations are looking for10-gigabit links, and where Verizon has 100-Gigabit capability, itcan quickly divide those fat pipes into narrower connections, hesaid. Verizon's 100-gigabit U.S. backbone technology forms the basis of a high-speed, low-latency network for financial trades that was inaugurated between Chicago and NewYork last month. It can complete a stock trade in as little as 14.5milliseconds, according to the carrier. The carrier doesn't yethave 100-gigabit capability across the Atlantic or Pacific but isworking on it, Wellbrock said. Also on Friday, Verizon said it has begun to use the same generalarchitecture for high-speed land-based networks, such as those inNorth America and Europe, that it already uses for its connectionsacross oceans. That architecture, based on a mesh of cables, givestraffic across its core network more alternate routes to take ifone cable breaks. This is a step up from a ring architecture, inwhich the network recovers by sending bits the other way around thering if one spot on it is damaged. This has limitations. "If you had two outages at the same time, you were out ofbusiness," Wellbrock said. Verizon already has mesh networks across the Pacific and across theAtlantic, each with eight alternate paths. Traffic can be reroutedover the quickest path across the mesh in the event of a disaster.Because of the trans-Pacific mesh, Verizon's network recoveredafter its cables were damaged in the earthquake, aftershocks andtsunami that hit Japan last year, according to the carrier. "It'sgotten us out of a lot of jams," Wellbrock said. Now, Verizon is building that capability into high-capacityland-based networks in a global initiative, upgrading not just thecarrier's domestic U.S. system but also networks in key marketselsewhere in the world. The move is designed to bring greaterreliability to enterprises' high-speed links. This will be agradual process, Verizon said.
