Description

The Controller Area Network (CAN)/Multi Area Network (MAN)/Wide Area Network (WAN) Optical Networking Brick addresses optical networking when implemented as part of the network backbone. Storage-Area Networks (SANs) can also use this technology, but those standards will be architected in the server environment area of the NIH Enterprise Architecture. These technologies are also used to attach to the backbone.

Comments

All new network elements at NIH must support Internet Protocol Version 6 (IPv6).
Tactical and strategic products were selected to leverage NIH's investment in products that are a proven fit for NIH's known future needs. Leveraging baseline products in the future will minimize the operations, maintenance, support and training costs of new products.
Some baseline products have been designated retirement and containment. These products are either not as widely or successfully deployed at NIH, or they do not provide as much functionality, value, or Total Cost of Ownership as the selected tactical and strategic products.
