I was able to compile it, but I could not get it to run successfully. But I don’t think that multicast is what I need. With my current setup, I am able to run some of the test programs successfully, but not others.
WebAug 2, 2024 · The transferred RDMA packets are marked with layer 3 DSCP, layer 2 Priority Code Points (PCP) or with both. To extract priority information from the packet routers use either DSCP or PCP. In case PCP is used, the packet must be VLAN-tagged and the router must copy the PCP bits of the tag and forward them to the next network. WebJan 29, 2024 · I am using Windows 10 Enterprise x64 build 21H2 and suffering from udp multicast packet loss. To explain better I am using AES67 streams with having randomly packet loss. This happens on 2 different PC's with the same Windows builds. Also I have changed NIC cables etc. but still the same. Any help would be appreciated. Regards, Chris
WebRDMA can significantly improve the robustness under failures (2x∼4x higher throughput under 0.5%∼10% link loss ratio) and improve the overall network utiliza-tion by up to 47%. … WebPacket loss is usually caused by network congestion where packets are sent faster than the receiver or switch can process. Conventional ethernet silently drops packets and expects retransmission if data is sent too fast. It is this packet drop that causes huge hits to latency and throughput. Exadata avoids packet drops by using two specific ...
