Packet Loss in High Data Rate Internet Data Transfer for eVLBI
نویسندگان
چکیده
VLBI is gradually moving to the point where Gbps data rates are becoming routine. A number of experiments have shown that the internet can be used at data rates of several hundred Mbps on production networks. However use of the network is accompanied by packet loss. The paper discusses the statistics of packet loss as found by recent tests and investigates the expected effect of packet loss on correlator performance and signal to noise ratio on eVLBI observations. The relative merits of UDP versus TCP are also discussed.

متن کاملFeature Extraction to Identify Network Traffic with Considering Packet Loss Effects
There are huge petitions of network traffic coming from various applications on Internet. In dealing with this volume of network traffic, network management plays a crucial rule. Traffic classification is a basic technique which is used by Internet service providers (ISP) to manage network resources and to guarantee Internet security. In addition, growing bandwidth usage, at one hand, and limit...

In this paper, loss probabilities and steady state probabilities of data packets for an asynchronous transfer mode (ATM) network are investigated under the buffer division and push-out schemes. Data packets are classified in classes k which arrive in Poisson fashion to the service facility and are served with general service rate under buffer division scheme, finite buffer space N is divided in...

متن کاملRate Based Congestion Control over High Bandwidth/Delay Links
As the network bandwidth and delay increase, traditional dominant transfer protocols on the Internet like TCP have shown inefficiency and instability to many applications involved in huge amounts of data transfer. We present in this paper a rate based congestion control algorithm as an application level solution. This algorithm is deployed in our SABUL high performance data transfer protocol, w...
