Sunrise Consultancy is a medium-sized consulting firm that operates 17 offices around the world (Dallas, Chicago, New York, Atlanta, Miami, Seattle, Los Angeles, San Jose, Toronto, Montreal, London, Paris, Sao Paulo, Singapore, Hong Kong, Sydney, and Bombay). They have been using Internet connections to exchange email and files, but the volume of traffic has increased to the point that they now want to connect the offices via a WAN. Volume is low but expected to grow quickly once they implement a new knowledge management system. What type WAN service would you recommend? Why?
Given: 17 offices spread around world, using VPN to exchange emails and files so it is not time sensitive. They want to upgrade to higher data rate knowledge management system(higher real time usage). Assumption: Data is not time sensitive, low volume data presently but expected to grow, mesh topology is used for data exchange Already decided packet switched is better than circuit switched. The only real disadvantage of package switched network is that it is not as guaranteed as circuit switched. Explain
Choose and compare MPLS or IP(pros and cons) and recommend which is better of the packet switched networks.
