Abstract: A network interface controller (NIC) capable of facilitating fine-grain flow control (FGFC) is provided. The NIC can be equipped with a network interface, an FGFC logic block, and a traffic management logic block. During operation, the network interface can determine that a control frame from a switch is associated with FGFC. The network interface can then identify a data flow indicated in the control frame for applying the FGFC. The FGFC logic block can insert information from the control frame into an entry of a data structure stored in the NIC. The traffic management logic block can identify the entry in the data structure based on one or more fields of a packet belonging to the flow. Subsequently, the traffic management logic block can determine whether the packet is allowed to be forwarded based on the information in the entry.

Abstract: A data-driven intelligent networking system that can facilitate global fairness is provided. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow are acknowledged after reaching the egress point of the network, and the acknowledgement packets are sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and enforce global fairness on a per-flow basis.

Abstract: A pet bowl includes a unitary housing having a front portion and a rear portion. The housing defines an internal chamber having a bottom wall upon which the housing sits in a first/dispensing orientation and a rear wall upon which the housing sits in a second/storage orientation. The housing also includes a first receptacle formed at the rear portion and a second receptacle formed at the front portion. A fluid flow port defined in the housing provides fluid communication between the internal chamber and the second receptacle. A handle is formed by a sidewall of the second receptacle defining a first lip, and a groove in the bottom wall defining a second lip. The housing may further include a transition wall angled from the bottom wall and rear wall, the housing configured to sit on the transition wall in a third/draining orientation.
