These networks may be dedicated networks or may be shared with traditional Ethernet applications. In the WAN environment TCP will ensure data reliability, manage network congestion, and adapt retransmission strategies to WAN delays. The Cisco Metro 1500 is a protocol-independent, cost effective, DWDM solution that supports 32 data channels over one fiber pair. Using the Metro 1500 platform, enterprise customers can extend distance and move large amounts of data quickly and transparently between sites. Applications include data sharing and disaster recovery.
Connectivity is achieved at both the central and simulated remote locations.
Within the IBM PartnerWorld storage demo, two PIX firewalls provide secure VPN tunnels over the simulated WAN environment that help ensure data security beyond the local network boundaries. The Cisco 3600 family provides solutions for data, voice, video, hybrid dial access, VPNs, and multiprotocol data routing. The high-performance, modular architecture protects customers' investment in network technology and integrates the functions of several devices into a single, manageable solution. In the PartnerWorld demo, Cisco 7200VxR is used as the WAN edge router connecting the remote locations for storage and other data traffic. The Cisco 3640 series router is deployed as the WAN edge router at the remote location providing WAN connectivity to the central location.
