Many enterprise networks have grown far beyond a single large site to span tens to hundreds of branch offices across the globe, each connected over VPNs or leased lines. With the emergence of the globally-connected enterprise and the trend towards enterprise all-IP convergence, including transitioning the enterprise PBX to VoIP servers, IP-based audio/video conferencing for telepresence has challenged the notion that bandwidth is abundant in the enterprise. We take a first look at media conferencing traffic in the global enterprise and, by instrumenting measurement of call quality and network statistics, we quantify the impact on call quality for a range of factors in the enterprise, such as wired vs. wireless access, inter- vs. intra- branch office communication, QoS mechanisms like VLAN tagging and DiffServ DSCP marking, and VPN vs. public Internet access.
