DATA CENTER PATH SWITCH WITH IMPROVED PATH INTERCONNECTION ARCHITECTURE
First Claim
Patent Images
1. A data center path switch, comprising:
- a set of ports, wherein each port within the set of ports is configured to receive data streams from an external medium, and to transmit data streams to an external medium;
a path interconnection unit having an ingress side with a set of paths equal to the number of ingress ports in the set of ports, and an egress side with a set of paths equal to the number of paths on the ingress side, and an electrical based switching fabric that is configured to switch data streams on any one ingress side path to any one egress side path; and
a control unit connected to the path interconnection unit configured to control the switching fabric to switch data streams from a path on the ingress side to a path on the egress side; and
wherein the latency of data streams switched from a receiving port to a transmitting port is less than 500 nsec.

Abstract
A data center path switch architecture permits path switching of the signal path of incoming signals to one or more output paths in real time without the need for manual intervention, and without delays associated with current data center network switches. In this architecture, a switching core capable of switching signals directly from the ingress of the switching core to alternate destination ports in real time, either under software or hardware control.

18. A data center path switch, comprising:
-
a set of ports in a one RU configuration having a capacity that is scalable from 16 ingress ports and 16 egress ports to at least 128 ingress ports and 128 egress ports, wherein each port within the set of ports is configured to receive data streams from an external medium, and to transmit data streams to an external medium; a path interconnection unit having an ingress side with a set of paths equal to the number of ingress ports in the set of ports, and an egress side with a set of paths equal to the number of paths on the ingress side, and an electrical based switching fabric that is configured to switch data streams on any one ingress side path to any one or more egress side paths; and a control unit connected to the path interconnection unit configured to control the switching fabric to switch data streams from a path on the ingress side to a path on the egress side.
