Bandwidth oversubscription
New Application & Contention
One thought: Bandwidth oversubscription, application contention, ISP routing issues and since everything runs on IP now,.
Organizations are being challenged with problems such as
Bandwidth oversubscription where the application don’t get the bandwidth they need to run because the ISP link is overstaurared
Application Contention where mission critical applications get starved out of the bandwidth they need because other low priority applications and abusing bandwidth usage
Lack of peering agreements between ISPs causes traffic from one ISP to be dropped by the other resulting in loss of information.
TCP inefficiencies that cause higher recovery times on packet loss, poor utilization of link bandwidth over longer distances and higher latencies for dial-up and broadband clients.
How do organizations cope with this problem today? Keep adding more bandwidth. Why doesn’t it work? Because applications continue to suck more bandwidth when available. Its not how much but how well do you use your bandwidth….next slide

F5 approached the ISP link problem by combining a set of optimization capabilities designed specifically for the ISP links in one integrated platform. We dramatically improve ISP link performance by:
Prioritizing applications by setting up policies to make sure that those mission critical apps like VoIP are given priority over less critical applications like HTTP.
Provide an instantaneous boost in bandwidth savings and eliminate the need to add more bandwidth with Powerful compression
iRules provides organizations the flexibility to create custom traffic policies to work around ISP routing issues and choose the link with the best QoS for a specific application.
Improve end use response times and remove TCP inefficiencies – For all types of clients – Dial-up, Broadband – irrespective of where the end users are. Could be next door or half way around the world - over longer distances
Let us put this in play and look at some real world scenarios….next slide

Customer here is a large ecommerce business.
Challenge they were facing was that their web portal was hogging all the bandwidth on the secondary link and causing the application to starve. When the primary link was up, there was no problem but when it failed, the secondary link was not big enough. Since about 70% of their business was done via , this was causing a big loss in revenue and orders were being lost….. Their initial approach was add more bandwidth but realized that the more bandwidth they had, the more bandwidth the web application was going to use…next slide..
With LC, they were able to solve this challenge by ensuring that the Web application didn’t take all the bandwidth on the secondary link. With the combination of Rate Shaping and iRules, they were able to create a custom policy provide a certain amount of bandwidth to the . There were no more lost orders, increased profitability and dramatic cost savings from not having to add more bandwidth.

10. Why Should You Buy BIG-IP LC?
Have you considered multiple ISPs for high availability?
Is your ISP not meeting the desired bandwidth and reliability Service Level Agreements (SLAs)?
Is your business losing money from ISP downtime?
Are you considering BGP as an multi-homing option?
Are you always looking to add extra ISP lines or bandwidth to solve your business problems?
Are some of your mission critical applications getting starved out of bandwidth?
