Abstract: The present disclosure describes a networking switch of a network and method for operating the networking switch. The networking switch communicates within the network using datagrams, such as packets and/or frames. The frames include packets of a first communication protocol or layer having headers of the first communication protocol or layer. In some situations, the packets of the first communication protocol or layer are embedded with packets of a second communication protocol or layer. Often times, one or more fields of headers of the first communication protocol or layer convey substantially similar or redundant information, such as routing information to provide an example, as one or more fields of headers of the second communication protocol or layer. In these situations, the networking switch can compress the one or more fields of the headers of the first communication protocol or layer

Abstract: A system, method and a computer readable medium for processing packets transmitted using relaxed order in an ordered multi-path network are provided. Packets associated with a data flow from the ordered multi-path network are received out of order. The received packets are reassembled into a sequential order, without gaps, prior to being delivered to a protocol stock for sequential processing.

Abstract: Systems and methods for handling virtual machine packets are provided. In some aspects, a method includes receiving, by a network interface controller, an indicator of a packet from a virtual machine. The indicator bypasses a virtual switch coupled to the virtual machine. The method also includes determining, in response to receiving the indicator, whether the packet is designated for accelerated processing. The method also includes providing the indicator to the virtual switch for processing if the packet is determined not to be designated for accelerated processing. The method also includes processing, by the network interface controller, the packet for transmission if the packet is determined to be designated for accelerated processing.

Abstract: A system, method and a computer readable medium for reducing hash polarization in a network, are provided. A field in a packet is identified at a first device in a network that propagates the packet though the network. The field is immutable at the first device in a network but is mutable as the packet propagates to other devices. Based on a value of the field, a hash function is selected from multiple hash functions such that a different hash function is selected for a different value of the field. The selected hash function determines a resource within the first device that identifies one of the other devices in the network next to receive the packet from the first device.
