Embodiment Construction

[0019] figure 1 A computer system 100 is shown for authenticating a logical port of a virtual machine. Computer system 100 includes a plurality of host computers configured with software and coupled by a data communications network. exist figure 1 In , the computer system 100 is vertically divided into four layers for users, logical network, virtual network and hardware. Computer system 100 is also divided horizontally into a data plane on the left and a control plane on the right.

[0020] In the data plane, hardware includes the physical network interface (P-NIC), central processing unit (CPU), random access memory (RAM), storage devices, local area network (LAN) and wide area network (WAN). In the data plane, a virtual network includes a hypervisor, a virtual switch (V-SW), and a virtual machine. The user layer in the data plane includes a guest operating system (OS) and user applications.

[0021] In the control plane, the hardware also includes the same or differen...

Abstract

A computer system authenticates a logical port for a virtual machine. A logical network maintains logical network data for a logical switch having the logical port. A virtual switch identifies a logical port authentication request for the virtual machine and transfers the logical port authentication request. A logical port authenticator receives the logical port authentication request and transfers the logical port authentication request for delivery to an authentication database. The logical port authenticator receives a logical port authentication response transferred by the authentication database that grants the logical port authentication request for the virtual machine and transfers authorization data for the logical port. The virtual switch transfers user data for the virtual machine when the virtual machine uses the logical port responsive to the authorization data.

Description

[0001] M. Naraparedi and A. Catreca [0002] related application [0003] This application is related to and claims priority to U.S. Nonprovisional Patent Application 15 / 387,828, entitled "LOGICAL PORT AUTHENTICATION FOR VIRTUAL MACHINES," filed December 22, 2016, the entire contents of which are incorporated by reference into this article. Background technique [0004] Computer hardware executes operating system software and user application software. Computer hardware includes components such as a central processing unit (CPU), random access memory (RAM), network interface cards (NICs), and data storage drives. The CPU executes the operating system software to control the computer hardware. The CPU executes user application software to interact with operating system software. Operating system software controls computer hardware on behalf of user application software. [0005] Virtualization software was introduced to eliminate the interface between computer hardware an...
