Connecting network deployment units
First Claim
1. A method, comprising:
- providing a first deployment unit comprising a first tier of network switches and a second tier of network switches, each switch of the first deployment unit being connected within the first deployment unit to every other switch of the first deployment unit, wherein the first tier of network switches has a greater number of network switches than the second tier of network switches;
providing a third tier of network switches; and
connecting a switch of the second tier of network switches within the first deployment unit to only one switch of the third tier of network 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.
