Dynamic load balancing of network traffic The Hyper-V Virtual Switch now automatically performs dynamic load balancing in order to move traffic streams between different NICs within a NIC team in order to share the network traffic load as equitably as possible. Previously in Windows Server 2012, the Hyper-V Virtual Switch provided simultaneous failover and load distribution capabilities, but it didn’t ensure load distribution for teamed NICs in a balanced manner. Coexistence with third-party forwarding extensions To better support Hyper-V Network Virtualization scenarios in multitenant environments, the Hyper-V Virtual Switch now allows third-party forwarding extensions installed on the switch to forward packets for either the customer address space or the physical address space using hybrid forwarding. Third-party forwarding extensions can also apply other policies, such as ACLs and QoS, to both the NVGRE and the non NVGRE-encapsulated tra ffic. Improved network tracing To better enable troubleshooting problems that might arise, network traces now contain switch and port configuration informa tion.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
