Abstract

The invention provides a message forwarding method. Specifically, the method comprises the following steps that an SR-IOV network card performs two-layer forwarding on a received Ethernet message to acorresponding port. By adoption of the message forwarding method and device provided by the invention, the problem of limitation of message forwarding between local virtual machines in related technologies is solved, thereby effectively expanding the deployment and application scenarios of the SR-IOV network card.

Description

technical field [0001] The present invention relates to the communication field, in particular to a message forwarding method and device. Background technique [0002] With the continuous development and wide application of virtualization technology, changes in I / O performance of virtualization technology have become more and more prominent. SR-IOV (Single Root I / O Virtualization) is increasingly appearing in network function virtualization solutions. SR-IOV technology is a hardware-based virtualization solution that can significantly improve performance and scalability. The SR-IOV standard allows efficient sharing of PCIe (Peripheral Component InterconnectExpress, fast peripheral component interconnection) devices between virtual machines, and it is implemented in hardware to obtain I / O performance comparable to that of using physical network cards . [0003] SR-IOV technology is used to implement I / O device sharing in a virtualized environment. It inherits Intel VT-d te...
