WAN技術之利用及移行計畫：根據IDC進行聲音・數據服務調査

Abstract

This IDC study presents the results of an IDC survey on voice and data networking conducted in late 2007. This survey queried decision makers in large United States-based enterprises on their current voice and data networking implementations, usage, and migration plans.

"Survey results indicated strong use of broadband and IP VPN solutions as well as the continued steady migration away from frame relay, ATM, and private line networks. It also underscored businesses' need for increased bandwidth and the growing trend to purchase bundled solutions of WAN connectivity and local access." - Rena Bhattacharyya, research manager, Business Network Services
