meet challenge existing emerging competitors. Statistics indicate that mainframes will continue platform store access this business-critical enterprise data. fact, more than data large enterprises continues processed IBMcompatible mainframe platforms.
Communications protocols enterprise
ESCON (200 Mbit/s) most common communications protocol used mainframes networked with other mainframes storage devices. According Strategic Research, storage capacity doubles every years, resulting increased requirement networked, high-speed mainframe links. need connecting mainframes, enterprise servers, storage devices, directors users across multiple locations drives need extend ESCON across Metropolitan Area Network (MAN). same time, FICON* (1.25 Gbit/s) emerging higher speed derivative ESCON. International Data Corporation forecasts that 2002, more than external systems will Fibre Channel-based. These data rates used mainframes into telecommunications architecture. Therefore, network infrastructure must scalable flexible enough migrate protocols like FICON Fibre Channel. Fibre Channel close relative FICON.
future-proof solution:
Supporting mainframe communications
Enterprises have three options addressing their remote mainframe communications requirements:
Convert native mainframe protocols telephony-standard interface rates such DS-3. Transmit protocols native format connecting channels Dense Wavelength Division Multiplexing (DWDM) platform using dark fiber connectivity. Obtain dark wavelengths from carrier.
OPTera Metro's unique Universal Optical Interface accepts protocols their native data rates, thereby eliminating protocol conversion. This reduces costs management complexity while increasing network reliability.
OPTION Convert protocols transmit over telecommunications network
this option, enterprise uses carrier's infrastructure connectivity. This infrastructure cannot accommodate mainframe data rates. Therefore, enterprise must convert their mainframe protocols into format that accommodated carrier's infrastructure. devices used translate ESCON channels into traditional MAN/WAN interface format result higher initial expenditure increased network management complexity. added process channel conversion will also have negative effect data integrity throughput speeds. Additionally, network robustness decreases because additional points failure incorporated into this solution.

Increased flexibility through rate protocol independence
OPTera Metro capable carrying optical, digital protocol, including ESCON, FICON, Ethernet, Fibre Channel, FDDI OC-n through common Universal Optical Interface. This flexibility enables enterprise automatically migrate next generation interfaces services automatically, without having re-provision network.
OPTera Metro: Reliable, future-proof mainframe communications
critical, competitive importance data organization driven need realtime, high bandwidth applications processing data. Equally important high-speed networking solutions accessing this stored information from servers workstations. Regardless user enterprise carrier OPTera Metro provides reliable, survivable platform connecting businesses their mainframe data ensuring business continuity event catastrophe. OPTera Metro's flexibility scalability remove network challenges usually associated with extending mainframe protocols across guarantee future-proof means migrating optical protocols data transmission.
Instantaneous survivability
With OPTera Metro, enterprise enable less than millisecond protection switching wavelength basis, enabling them choose which wavelengths will protected. This provides optical layer survivability routing signals around fiber failures.
OPTION Lease dark wavelengths
While OPTera Metro deployed large enterprise customers with multiple locations access dark fiber, also provides unique opportunity carriers expand their services portfolio. Carriers that adopt DWDM technology able offer dark wavelengths enterprises tariffed service, much like DS-3s. carrier offering native ESCON service using OPTera Metro adds value enterprise taking network design, implementation management issues, while offering robust architecture dark fiber infrastructure mainframe connectivity. Enterprises different sizes enjoy greater economies scale because dark wavelengths allocated individual customers share same physical infrastructure. Carriers benefit immediately adding protocol extension their services portfolio, long term, being able accommodate services quickly cost-effectively.
Increased scalability
OPTera Metro supports protected, full-duplex channels single fiber, enabling enterprises connect more remote users cost-effectively corporate databases mainframes. Capacity increased connections channels protected optical layer. enterprise choose enable protection per-wavelength basis, depending survivability requirements network equipment.
