Explicit transport error notification (ETEN) for error-prone wireless and satellite networks
This paper is a summary of the BBN Technical Report No. 8333, "Explicit Transport Error Notification for Error-Prone Wireless and Satellite Networks." In this study we discuss two types of Explicit Transport Error Notification (ETEN) mechanisms: (i) per-packet mechanisms that notify endpoints of each detected corruption; and (ii) cumulative mechanisms that notify endpoints of aggregate corruption statistics. We have implemented the proposed mechanisms in the ns-2 simulator. We present simulation results on performance gains achievable for TCP Reno and TCP SACK, using ETEN mechanisms over a wide range of bit error rates and traffic conditions. We compare TCP Reno and TCP SACK enhanced with ETEN mechanisms against TCP Westwood, which uses a bandwidth estimation strategy in place of the traditional AIMD congestion avoidance algorithm. We discuss two issues related to the practical deployment of ETEN mechanisms: corruption detection mechanisms (and their co-operation with ETEN-ba...
