Access Router/Switch Brick

Home > Architecture Library > Review by Architecture Type > Technology Architecture > Access Router/Switch Brick

Description

Access routers and switches connect subnets to the distribution layer. In some cases, the access router/switch functionality is combined with the distribution and workgroup layer switches so that a single box performs the functions of access, distribution and/or workgroup layers.

Comments

All new network elements at NIH must support Internet Protocol Version 6 (IPv6).
Each network layer has required features for routers and switches for a given OSI layer. The following features are required for routers and switches in this network layer:
- OSI Layer 4: SIP and H.32x
- OSI Layer 3: HSRP, Port Channel, OSPF, EIGRP, SNMP, Device Security, Tunnels, and QoS
- OSI Layer 2: Multicast, 802.1q, 802.1d, 802.1s & 802.1w, Ether Channel, and 802.1p
- OSI Layer 1: Copper (100/Full and 1G/Full), MMF (100/Full and 1G/Full), and SMF (1G/Full)
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.
