Abstract: Embodiments monitor one or more inventory items corresponding to a vehicle. Embodiments generate a trip plan including, for the vehicle, a start location, an end location, and one or more stops, and for each of the inventory items, a pickup location and a drop off location corresponding to the one or more stops. Embodiments, for each of the inventory items, detect that the vehicle has entered the pickup location based on the trip plan and in response automatically link a sensor to the inventory item. Embodiments, for each of the inventory items, detect that the vehicle has entered the pickup location based on the trip plan and in response automatically unlink the sensor from the inventory item.

Abstract: System and method for using multiple global identification subnet prefix values in a network switch environment in a high performance computing environment. A packet is received from a network fabric by a first Host Channel Adapter (HCA). The packet has a header portion including a destination subnet prefix identifying a destination subnet of the network fabric. The network HCA is allowed to receive the first packet from a port of the network HCA by selectively determining a logical state of a flag and, selectively in accordance with a predetermined logical state of the flag, ignoring the destination subnet prefix identifying the destination subnet of the network fabric.

Abstract: System and method for supporting intra- and inter-subnet address resolution in a network environment using the same linear forwarding tale (LFT) for both the intra- and inter-subnet forwarding. Subnet prefix values in global route headers (GRHs) are used for linear forwarding table (LFT) lookup in a high performance computing environments. An exemplary can provide for use of an Inter Subnet Route Number (ISRN) embedded in the subnet prefix values in the GRHs for LFT lookup in a network switch environment in a high performance computing environment such as a network having an InfiniBand (IB) architecture. A method can provide, at a computer environment, including a network fabric, one or more subnets, each of which subnets are associated with one or more network switches or hosts. The system and method is compatible with legacy switches and nodes that are not conversant with the ISRNs.

Abstract: System and method for supporting shared multicast local identifiers (MLIDs) a high performance computing environment. In accordance with an embodiment, a shared MLID range can be configured such that each subnet within a fabric can utilize an MLID within a shared MLID range without the need to utilize a TCAM, or other memory, lookup of a MGID to MLID mapping.

Abstract: System and method for supporting flexible partition key (P_Key) mapping in a high performance computing environment. In accordance with an embodiment, when such computer environments comprise more than one subnet and/or forwarding domain that support inter-subnet partitions, the P_Keys comprising such inter-subnet partitions can change across domain boundaries. In such situations, a partition key of a packet can be updated upon entry to a new subnet and/or forwarding domain.

Abstract: The disclosed embodiments provide a system that operates a switch fabric. During operation, the system creates a set of virtual links for a first set of physical ports in the switch fabric. Next, the system uses a set of virtual port numbers to create a set of mappings between the set of virtual links and a second set of physical ports in the switch fabric, wherein the second set of physical ports is connected to the first set of physical ports using a single physical link. The system then uses the mappings to provide non-blocking behavior in traffic from the first set of physical ports to the second set of physical ports.

Abstract: A system and method can support packet switching in a network environment. The system can include an ingress buffer on a networking device, wherein the ingress buffer, which includes one or more virtual output queues, operate to store one or more incoming packets that are received at an input port on the networking device. Furthermore, the system can include a packet flush engine, which is associated with the ingress buffer, wherein said packet flush engine operates to flush a packet that is stored in a said virtual output queue in the ingress buffer, and notify one or more output schedulers that the packet is flushed, wherein each output scheduler is associated with an output port.
