Why RDMA and TCP for GigEVision are a step backwards

Why RDMA and TCP for GigEVision are a step backwards

The GigE Vision standard uses a UDP-based protocol called GVSP to facilitate image transfer using Ethernet. As data rates have increased, some manufacturers have encountered difficulty achieving performance using GVSP, particularly when data rates approach 10Gbps or higher. This has led to experimentation with TCP or RDMA protocols to mitigate those difficulties but we see these options converge the GigEVision standard with point-to-point protocols like CXP and USB.
