Load balancing modes: Address hash or Hyper-V port hash? When implementing a NIC team for datacenter networks, you will generally see the best load balancing and overall performance by configuring your team with: Teaming mode: Use Static or Dynamic ( LACP ) network teaming modes with intelligent core switches that provide support for teaming. Load balancing mode: Use Address hashing for network load balancing mode to gain the best level of bidirectional load balancing.

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). ONP fits into this picture by performing VTEP functions in hardware (at line rate). NFV is intended to address the problem caused by having to route/direct traffic from various sources through physical appliances designed to provide services like content filtering, security, content delivery/acceleration, and load balancing. It is hardware switch independent.

On Network Virtualization and SDN

Scott Lowe

According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware. What about virtualized load balancers? Is there a difference between network virtualization and Software-Defined Networking (SDN)? If so, what is the relationship between them? Is one a subset of the other?
