Abstract

The deployment and scaling of a network of electronic devices can be improved by utilizing one or more network transpose boxes. Each transpose box can include a number of connectors and a meshing useful for implementing a specific network topology. When connecting devices of different tiers in the network, each device need only be connected to at least one of the connectors on the transpose box. One or more of the deployed electronic devices (e.g., switches, transpose boxes) in the network can transmit data based on a backplane Ethernet standard, such as 10GBASE-KR, 10GBASE-KX4, or 40GBASE-KR4.
