Our business related to financial trading US Stock market we have a strong concern about availability of link (availability sure in our premises not concern to ISP matter issues). Our financial trading system / software are directly connected to US stock exchange so our core requirement is to link availability so we require a permanent cost effective solution / equipment for availability of our multiple links with bandwidth aggregation. In simple If anyone of my connection goes down it will never create an impact on my users who are using SSL based application until and unles my all 4 Internet connections will be down. I must have to keep this transparent from my users.I must want to retain these SSL based connections. I really appreciate for your reply
