Abstract: An approach is provided which a system selects a first virtual function from a plurality of virtual functions executing on a network adapter that includes a memory area. Next, the system allocates, in the memory area, a memory corresponding to the first virtual function. The system then stores one or more translation entries in the allocated memory partition, which are utilized to send data traversing through the first virtual function. As such, the system sends, utilizing one or more of the translation entries, the data packets from the network adapter to one or more destinations. In turn, the system dynamically resizes the memory partition based upon an amount of the memory partition that is utilized to store the one or more translation entries.

Abstract: A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address.

Abstract: Methods, systems and software products for configuring a virtual port for a physical server to support packets transfer between the physical server and other network nodes over a virtual network, comprising transmitting one or more configuration Protocol Data Units (PDU) of an extended Link Layer Data Protocol (LLDP) to a Network Interface Card (NIC) of a physical server connected to a network, the configuration PDU(s) comprising one or more extension Type Length Values (TLV) defining one or more virtual network settings for a virtual network port mapping the physical server in a virtual network. The NIC is configured to deploy the virtual network port to support exchange of packets between the physical server and one or more of a plurality of nodes of the virtual network by processing outgoing and incoming packets according to one or more virtual network virtualization protocols using one or more of the virtual network settings.

Abstract: In one embodiment, a computer program product includes a computer readable storage medium having program instructions embodied therewith. The embodied program instructions are readable/executable by a processor to receive, by the processor, a packet via a network fabric, the network fabric having a plurality of interconnected fabric switches. The embodied program instructions are also readable/executable by the processor to determine, by the processor, a path through the network fabric by consulting a source-routing table. Moreover, the embodied program instructions are readable/executable by the processor to store, by the processor, source-routing information to a packet header for the packet, the source-routing information including the path. In addition, the embodied program instructions are readable/executable by the processor to send, by the processor, the packet according to an indication in the source-routing information.
