全球WAN管理者的調查和觀點調查

企業廣域網（WAN）管理員對當今網絡的主要挑戰有什麼解決方案？

調查方法

在TeleGeography中，我們於2018年對IT專業人員進行了採訪調查，這些專業人員在全球各大公司（包括各個行業和規模的公司，主要是跨國公司）負責日常WAN管理和採購。同時，我們對行業中的10位知名專家進行了詳細採訪，並介紹了我們認為是未來趨勢的先驅的網絡場景。

分析內容

在本報告中，我們能夠通過與行業領先的網絡管理專家（共60人）進行訪談，研究和分享與以下項目有關的獨特經驗。

• 當前網絡配置：地理範圍，使用的服務，典型容量，首選供應商等。
• SD-WAN的採用：已實施或已規劃的實施-推薦的供應商類型，服務選擇的關鍵因素，推出策略等。
• 未來的網絡配置（採用SD-WAN之後）：MPLS使用狀態，向混合WAN的計劃遷移，未來容量規劃等。

本報告不僅介紹了各公司專家的回答（網絡配置，採購決策，SD-WAN的採用，SD-WAN的未來影響等），而且還介紹了整個行業的未來。它還描述了有關前景的專家分析。

How are WAN managers solving today's biggest networking challenges?

This one-of-a-kind survey report explores how real network decision makers are managing this moment in technology.

How We Did It

In 2018 TeleGeography surveyed IT professionals whose daily role includes managing and sourcing wide area networks for major corporations around the world.

We put special emphasis on finding decision makers who oversaw U.S. national, regional, and global corporate wide area computer networks.

Participants came from a number of industries, ranging from SMEs to Fortune 500. Most, however, were multinational enterprises with a median annual 2017 revenue of $10 billion. Additional in-depth interviews were conducted with 10 standout respondents who represented networking scenarios that we saw as prescient of future trends.

The Analysis

Our laser focus led us to 60 top-tier respondents who shared their unique experiences in network management, specifically as it relates to:

• Current network configuration, such as geographic extent, services used, typical capacities, and preferred suppliers

• SD-WAN adoption - completed or as it pertains to future plans-including preferred vendor types, key factors in selecting service, and roll out strategies

• Future network configurations after SD-WAN adoption including use of MPLS, moving to hybrid WANs and future capacity plans

Our resulting report details not only responses to questions covering network configuration, sourcing decisions, SDWAN adoption, and SD-WAN's impact on the future, but TeleGeography's expert analysis of standout trends.
