Toward an understanding of the processing delay of peer-to-peer relay nodes
2008
2008 IEEE International Conference on Dependable Systems and Networks With FTCS and DCC (DSN)

In this work, based on an extensive set of Internet traces, we pursue an understanding of the processing delays incurred at relay nodes and their impact on the application performance. ...
nodes; and 3) we show that, serious VoIP quality degradation may occur due to relay processing, thus we have to monitor the processing delays of a relay node continuously to prevent the application performance ...
In addition, we analyze the sampled processing delays to gain an understanding of the workload pattern of Internet nodes, the effect of packet size on relay processing, and the instability of processing ...

The bitcoin peer-to-peer network has drawn significant attention from researchers, but so far has mostly focused on publicly visible portions of the network, i.e., publicly reachable peers. ...
We also empirically evaluate a method that uses timing information to re-identify the peer that created a transaction against unreachable peers. ...
We believe that our work sheds more light into a more hidden part of the Bitcoin network and is a valuable step towards better understanding the Bitcoin ecosystem as a whole. ...

By exposing opportunities to improve the delay between two nodes, TIVs can help myriad applications that seek to minimize end-to-end latency. ...
Triangle inequality violations (TIVs) are the effect of packets between two nodes being routed on the longer direct path between them when a shorter detour path through an intermediary is available. ...
The random selection of one bad triangle per node pair intends to not bias the results toward pathological senders or receivers, or toward the properties of the most severe violations, which might differ ...

Our model of peering consists of ASs leasing dark fiber to an Internet Exchange Point (IXP), and an Ethernet connection to a public peering fabric to send and receive traffic. ...
We model geographical constraints in peering by assigning each node to a set of locations where each location roughly corresponds to an IXP. ...
A relaying service is the forwarding of packets from an ingress channel to an egress channel. Relay prices indicate the amount charged to users for relaying a unit volume (e.g. mbps) of traffic. ...

In fact, only 5% of the communica-tions experience an extra delay that may degrade the QoS due to the use of Relays. Furthermore, the amount of extra transit traffic generated is only 6%. ...
However, the Internet has evolved, and nowadays the largest portion of the traffic is due to peerto-peer (p2p) applications. ...
During the process a large num-ber of servers have to measure the RTT to the client, which constitutes a high probing load. ...

Its soul purpose has been the effective utilisation of IPv4 public addresses by enabling the sharing of a single (or few) IPv4 address(es) by a large number of nodes within a private network. ...
Unfortunately, it imposes a great obstacle with respect to Peer-to-Peer (P2P) applications. To address this issue, different NAT traversal techniques have been proposed. ...
If both nodes are behind symmetric routers, the relay option is used to traverse the NAT. Fairness is an issue in this case where the relay node has to provide more bandwidth to the firewalled node. ...
