First Claim
1. A data center utilizing an architecture minimizing Internet Protocol (IP) routing therein, the data center comprising:
- one or more service edge network elements located in the data center, wherein a sub-IP network operating at Layers 0, 1, and 2 communicatively couples the one or more service edge network elements to one or more customer edge network elements located at or near demarcation points between a customer edge network and a service provider network, wherein the one or more customer edge network elements and the one or more service edge network elements are configured to provide direct user access to the data center for a plurality of users; and
a control system communicatively coupled to the one or more service edge network elements and the sub-IP network, wherein the control system is configured to control resources on the sub-IP network and the data center for the plurality of users,wherein traffic flows on the sub-IP network for the plurality of users are aggregated and groomed on the sub-IP network into aggregate connections destined for a specific device comprising one of a Top of Rack (TOR) switch and a server within the data center, through the control system, andwherein the aggregate connections are any of wavelengths, Optical Transport Network (OTN) containers, Ethernet connections, Multiprotocol Label Switching (MPLS) connections, and MPLS-Transport Profile (MPLS-TP) connections between aggregation devices in the sub-IP network and a network element in the data center, and wherein the network element in the data center is configured to connect to the specific device via the one or more service edge network elements, based on the control system.

10. A method to minimize Internet Protocol (IP) routing in a data center using direct user access, the method comprising:
-
controlling aggregation and grooming of traffic flows associated with a plurality of users on a sub-IP network operating at Layers 0, 1, and 2, wherein the plurality of users are configured to access the data center directly via the sub-IP network; receiving the traffic flows on the sub-IP network in an aggregate connection with the traffic flows contained therein; and providing the traffic flows to devices in the data center, wherein the devices comprise switches or servers, and wherein the aggregation and grooming of the traffic flows is based in part on the destinations of the traffic flows, wherein traffic flows on the sub-IP network for the plurality of users are aggregated and groomed on the sub-IP network into aggregate connections destined for a specific device comprising one of a Top of Rack (TOR) switch and a server within the data center, through the control system, and wherein the aggregate connections are any of wavelengths, Optical Transport Network (OTN) containers, Ethernet connections, Multiprotocol Label Switching (MPLS) connections, and MPLS-Transport Profile (MPLS-TP) connections between aggregation devices in the sub-IP network and a network element in the data center, and wherein the network element in the data center is configured to connect to the specific device via the one or more service edge network elements, based on the control system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
