Reshaping Enterprise Communications - The Next Generation WAN

Wide Area Networks (WANs) are changing to meet the growing and evolving demands of the enterprise marketplace. Companies are increasingly adopting a three-tiered WAN architecture to accommodate and optimize capabilities for the specific needs of the data center, branch, and remote office. SIP (Session Initiation Protocol) trunking adoption is helping companies consolidate voice and data delivery onto the WAN, but compatibility issues are hampering initiatives. IT leaders are slowing bringing IPv6 into focus, but true adoption is slowed by a lack of urgency and sufficiently capable, and widely available “band-aid” solutions. Organic growth is the top impetus driving budget, bandwidth, and architecture advancements and though IT leaders expect exceptional growth in bandwidth demand, they only expect their WAN budgets to increase by only 11.2% by 2012.
