    Abstract: The present disclosure relates to a switch for a network, and specifically the dynamic allocation of buffer memory within the switch. A communication channel is established between the switch and a network device. The switch configures and allocates a portion of memory to a receive socket buffer for the established channel. Upon receipt of a signal from the network device, the switch allocates a second portion of memory to the receive socket buffer.

    Abstract: A system and method can support efficient packet switching in a network environment. The system can comprise an ingress buffer on a networking device. The ingress buffer operate to store one or more incoming packets that are received at an input port on the networking device, wherein the input port is associated with a plurality of source virtual lanes (VLs). Furthermore, the ingress buffer operate to reallocate buffer resource in the ingress buffer from being associated with a first source VL in the plurality of source VLs to being associated with a second source VL in the plurality of source VLs, and send an initial credit update to the input port for the first source VL and the second source VL.

    Abstract: In a method for processing packets, a storage region for a packet is determined based on a queue with which the packet is associated. The storage region includes a committed area reserved for storage of packets associated with the queue, and an area that is shared by multiple queues for packet storage. A first part of the packet is stored in the committed area, a second part is stored in the shared area, and both parts are accounted for. A network device for processing packets comprises a plurality of queues and a storage area including a committed area and a shared area. The network device further comprises a packet queuing engine configured to store a first part of a packet in the committed area, store a second part of the packet in the shared area, and account for the storage of the first and the second parts of the packet.

    Abstract: The present disclosure describes a method and apparatus for network traffic processing in a non-uniform memory access architecture system. The method includes allocating a Tx/Rx Queue pair for a node, the Tx/Rx Queue pair allocated in a local memory of the node. The method further includes routing network traffic to the allocated Tx/Rx Queue pair. The method may include designating a core in the node for network traffic processing. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
