Virtual switches are established in a host system of a computing environment. Each virtual switch of the virtual switches includes a respective virtual switch port grouped within a shared port group of virtual switch ports. The virtual switch ports of the shared port group are in communication with a common physical network adapter of the host system. The virtual switch ports of the shared port group share a single physical port of the physical network adapter as part of a common physical link aggregation group (LAG).

A segment based switching architecture with hybrid control providing flow control in software defined networking (SDN). An SDN controller controls top tier macro-flows and virtual segment backbone connections in a network, and an SDN network edge device controls and manages micro-flows that are attached to the SDN network edge device. The SDN network edge device controls and manages the micro-flows locally without using a southbound API. The SDN network edge device learns flow information such as source information and incoming port information for all unknown micro-flows belonging to defined segments, and builds a virtual segment topology database for each segment. The SDN network edge device employs flow computation algorithms and micro-flow management in a distributed fashion. The virtual segment backbone connections are naturally exposed to the SDN controller through provisioning.

In one embodiment, a system includes a switch that has a processor and logic integrated with and/or executable by the processor, the logic being configured to create a message indicating addition, modification, or deletion of a static flow in a software defined network (SDN), wherein the static flow includes the switch and at least one other device in the SDN, and send the message to a SDN controller in a SDN-formatted structure. In another embodiment, a method includes creating a message, using a switch, indicating addition, modification, or deletion of a static flow in a SDN, wherein the static flow includes the switch and at least one other device in the SDN, and sending the message to a SDN controller in a SDN-formatted structure. Other systems and methods for reporting static flows to a SDN controller in a SDN are described according to more embodiments.

Systems and methods for hierarchical link aggregation are disclosed. A system for hierarchical link aggregation may include a network interface having a plurality of physical ports. A first plurality of the physical ports may be configured as member ports of a first link aggregation group (LAG). A second plurality of the physical ports may be configured as member ports of a second LAG. The first LAG and second LAG may be configured as member logical ports of a third LAG.
摘要:
A 10GBASE-T circuit is disclosed. The circuit includes a physical (PHY) integrated circuit and a media access control (MAC) integrated circuit. The PHY couples to a data transfer medium and carries out data transfers at a PHY data rate. The MAC integrated circuit controls access to the date transfer medium and couples to the PHY via a bidirectional link operating at a MAC data rate. Rate control logic detects the PHY data rate, and adjusts the MAC data rate to the PHY data rate. Changes to the PHY and MAC data rates may be made at rates higher than 1 Gbps.
