A modular network switch is disclosed. In an embodiment, removable interface modules and a switch circuit board (SMB) are housed in a chassis. Each of the interface modules includes a circuit board that is positioned in parallel with other interface modules. The SMB is oriented in a plane perpendicular to orientation planes of the interface modules, and the circuit boards are connected to the switch circuit board. A switch chip is electrically connected to SMB, and configured to switch network traffic between network connections of the interface modules. The chassis may include airflow regions separated by a divider with respective air intake vents. A power supply is housed in one of the regions and the SMB/interface modules are housed in another region. Power supplies provide power to the interface modules via a bus bar and provide power to the switch circuit board via a connection separate from the bus bar.

A new physical computer architecture that combines elements in a virtuous cycle to eliminate performance killing inefficiencies in compute systems and need never be physically repaired during its lifetime is described. The system comprises a three dimensional rectangular cube structure with integrated liquid cooling and a multi-dimensional direct network laced through it. The network comprises a distributed, dynamically adaptive, multiply-fault-tolerant routing protocol that can logically replace failed components.

Power management of a routing table, which comprises a plurality of hash tables, is provided by supporting various power domain configurations. Each power domain configuration can be associated with a different number of power domains than other power domain configurations. Each power domain can add vertical capacity to the entire routing table by adding a fixed number of buckets to each of the hash tables. Efficient power management can be achieved by switching between a lower power domain configuration and a higher power domain configuration during runtime based on the dynamic load conditions.

The present disclosure discloses a hybrid Power over Ethernet/Device Level Ring network in which power is delivered to connected devices on the same cable in which data are delivered, and the devices are configured to connect to the network in a daisy-chain fashion. The network of the disclosure may be configured to operate as a token ring. According to a further aspect of the present disclosure, a hybrid PoE/DLR network switch and a hybrid PoE/DLR network device for such a PoE/DLR hybrid network are disclosed.

An integrated router is provided. The integrated router includes at least one network interface, a power supply input, a power supply output, and a power cycling switch. The at least one network interface is operative to place a first network device in electronical communication with a second network device. The power supply input is operative to receive electrical power from a power supply. The power supply output is operative to provide the electrical power to the second network device. The power cycling switch electrically connects the power supply input to the power supply output and is operative to be toggled by a remote network device via the at least one network interface so as to power cycle the second network device.

Techniques to inspect packets to determine a destination node are provided. In one aspect, a Wake on Lan (WOL) packet may be received at a switch. A destination node of the WOL packet may be determined. An indication of the determined destination node may be sent to a management controller. The management controller may cause the destination node to awaken.

Power supply for a networking device may be provided. The networking device may comprise a first plurality of switch bars each comprising a first switch type arranged parallel to one another and a second plurality of switch bars each comprising a second switch type arranged parallel to one another.
