A new Request for Comments is now available in online RFC libraries. RFC 5236 Title: Improved Packet Reordering Metrics Author: A. Jayasumana, N. Piratla, T. Banka, A. Bare, R. Whitner Status: Informational Date: June 2008 Mailbox: Anura.Jayasumana at colostate.edu, Nischal.Piratla at telekom.de, Tarun.Banka at colostate.edu, abhijit_bare at agilent.com, rick_whitner at agilent.com Pages: 26 Characters: 57805 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-jayasumana-reorder-density-08.txt URL: http://www.rfc-editor.org/rfc/rfc5236.txt This document presents two improved metrics for packet reordering, namely, Reorder Density (RD) and Reorder Buffer-occupancy Density (RBD). A threshold is used to clearly define when a packet is considered lost, to bound computational complexity at O(N), and to keep the memory requirement for evaluation independent of N, where N is the length of the packet sequence. RD is a comprehensive metric that captures the characteristics of reordering, while RBD evaluates the sequences from the point of view of recovery from reordering. These metrics are simple to compute yet comprehensive in their characterization of packet reordering. The measures are robust and orthogonal to packet loss and duplication.
