“…The retransmission of the E-RTO and ER-SRTO algorithms might be too aggressive compared with the normal TCP fast retransmit. The ECN (Explicit Congestion Notification) nonce based algorithm (Welzl, 2008) uses the ECN nonce code point in the IP datagram header. The ECN capable sender sets the ECN nonce code point to 1 for original data segments, a value called ECN(1), and 0 (ECN(0)) for retransmitted data segments.…”

This paper describes the performance evaluation of the well-known spurious timeout detection methods implemented within TCP, Eifel, DSACK, and F-RTO, through experiments with the network emulator emulating handovers over LTE (Long Term Evolution) networks. Specifically, the emulator supports to insert the time-variant delay and packet loss in TCP streams. By taking account of the lossless handover in LTE, this paper shows the results for the cases only the delay spike is inserted, and both delay spike and packet loss are inserted. In the former case, the three methods show the similar performance, but in the latter case, the performance of Eifel is worse than the others. This paper also shows the results when two methods are used together for the delay spike and packet loss case, and indicates that the performance is not improved even if multiple spurious timeout detection methods are implemented.

TCP(Transmission Control Protocol ) uses a loss-based algorithm to estimate whether the network is congested or not. The main difficulty for this algorithm is to distinguish spurious from real network congestion events. Other research studies have proposed to enhance the reliability of this congestion estimation by modifying the internal TCP algorithm. In this paper, we propose an original congestion event algorithm implemented independently of the TCP source code. Basically, we propose a modular architecture to implement a congestion event detection algorithm to cope with the increasing complexity of the TCP code and we use it to understand why some spurious congestion events might not be detected in some complex cases. We show that our proposal is able to increase the reliability of TCP NewReno congestion detection algorithm that might help to the design of detection criterion independent of the TCP code. We find out that solutions based only on RTT (Round-Trip Time) estimation are not accurate enough to cover all existing cases. Furthermore, we evaluate our algorithm with and without network reordering where other inaccuracies, not previously identified, occur.

“…Due to its ability in indicating network congestions without packet dropping, ECN has been applied in hybrid wired-wireless networks to help control TCP behaviors [10][11][12][13]. One typical work is Wireless ECN (WECN) proposed by Peng [14].…”

Network congestions and wireless link errors are both potential reasons for packet losses in hybrid wired-wireless networks. Their coexistence necessitates the design of new mechanisms that can differentiate network states more precisely. In this paper, a method is proposed to distinguish between the two reasons of packet losses in hybrid wired-wireless networks (i.e., congestions and wireless link errors) and calculate the probability of network congestion in the former case. This method combines the information contained in CE bits of a sequence of ECN-enabled acknowledge packets to calculate the probability of network congestion; thus it is more accurate than methods using CE bits of a single acknowledge packet. Analysis on the effectiveness of the proposed method in calculating congestion probability is performed via simulations. The ability to differentiate precise network states helps a TCP source response to ECN feedback more adaptively. We discuss how to enhance existing TCP variants with the proposed method. Simulation results show that the enhanced TCP variants can effectively improve network performance.
