TECHNIQUE FOR FORWARDING AN INCOMING BYTE STREAM BETWEEN A FIRST WORKLOAD AND A SECOND WORKLOAD BY MEANS OF A VIRTUAL SWITCH

摘要

A technique for forwarding an incoming byte stream between a first workload and a second workload by means of a virtual switch, vSwitch, in a cloud environment is disclosed, the first workload being local to the vSwitch. A method aspect (in the vSwitch), comprises the steps of receiving the incoming byte stream at a first socket, determining a forwarding state of the incoming byte stream, piping, if the forwarding state indicates forwarding to a second socket, the incoming byte stream from the first socket to the second socket, wherein the second workload is another local workload having opened the second socket, and packetizing, if the forwarding state indicates that the second workload is remote to the vSwitch, the byte stream into a plurality of packets. A further method aspect (in the first workload) comprises the steps of opening, by an application running on the first workload, the socket on the vSwitch, transmitting, to the vSwitch, a first socket handle for the corresponding socket and a respective network context of the corresponding socket.
