Abstract:
Relay or overlay routing for IP networks has been well-documented in past years. However, the implementation cost of relay solutions has not yet been conclusively identified. Dynamic-relay routing relies on periodic probing for enhanced performance while static-relay routing uses less and non-periodic probes to measure latency and packet loss. For both types, there exists considerable research focused on understanding routing dynamics. However, the literature has insufficient exploration of relay attributes, such as stability and mechanisms for reducing the relay probing burden. This paper, in particular, examines relay statistical boundaries and characteristics, such as the number of hops in a minimum delay and relay path or Hop-To-Live (HTL) count inherited from the self-similar model of Internet data. The HTL is introduced in a novel analysis to assist in predicting minimum and stable relay paths while minimizing probing overhead. For doing so, our work is based on analyzing a wide-set on $ 19,460 $ Ping and $ 14,762 $ IPerf paths, respectively, of a network of $ 140 $ Planetlab nodes. Further, we briefly evaluated the performance of a new hybrid User Datagram Protocol and Transmission Control Protocol (UDP-TCP) relay streaming over an inexpensive relay selection mechanism managed by a stable HTL modeling. Here, we highlight a preliminary performance of applying a layer-3 and hybrid UDP-TCP streaming a replacement for the current TCP-based stream services, such as YouTube and Voice over IP (VoIP). The main results emphasize the unnecessary repetitive probing burden over the period of $ 24 $ hours instead of a careful set of measurements for capturing and predicting relay changes. This work validates this claim by presenting that our implemented HTL-based path estimation predicts stable relay paths for the hybrid UDP-TCP streaming to overcome the high drop-rates caused by the individual TCP or UDP streaming services.
