Virtual machines (VMs) are widely adopted today to provide elastic computing services in datacenters, and they still heavily rely on TCP for congestion control. VM scheduling delays due to CPU sharing can cause frequent spurious retransmit timeouts (RTOs). Using current detection methods, we find that such spurious RTOs cannot be effectively identified because of the retransmission ambiguity caused...
This paper presents the performance evaluation between IPv4 and IPv6 with Linux MPLS tunnel. MPLS Linux tunneling is used to transport IPv6 data stream over IPv4 network for interoperable IPv4 and IPv6 deployment. The performance metrics such as jitter, datagram/packet loss and bandwidth were measured in both TCP and UPD traffic flow. The experiment test-bed was constructed using virtual machine tool...
