Connecting network deployment units
First Claim
1. A method of connecting switches in a data center, comprising:
- providing a plurality of deployment units each comprising at least a first tier of switches and a second tier of switches, each of the first tier of switches connected to each of the second tier of switches within a given deployment unit using only connections between tiers of the given deployment unit;
providing a third tier of switches for connecting each of the plurality of deployment units to a network; and
connecting a selected switch of the second tier of switches within each deployment unit to only one selected switch of the third tier of switches.

Abstract
Efficient and highly-scalable network solutions are provided that each utilize deployment units based on Clos networks, but in an environment such as a data center of Internet Protocol-based network. Each of the deployment units can include multiple stages of devices, where connections between devices are only made between stages and the deployment units are highly connected. In some embodiments, the level of connectivity between two stages can be reduced, providing available connections to add edge switches and additional host connections while keeping the same number of between-tier connections. In some embodiments, where deployment units (or other network groups) can be used at different levels to connect other deployment units, the edges of the deployment units can be fused to reduce the number of devices per host connection.
