* * * * * * * * Competitive win Friendster was experiencing daily outages on the servers and network infrastructure based on the amount of concurrent connections, and the requirement to support content based load balancing. Customers were also experiencing connection problems which was affecting the company’s revenues. The F5 could not meet the technical requirements, and the NetScaler was able to meet and exceed the features offered by Foundry. These features included: Custom server ID persistence (not supported by F5) Connection throttling URL hashing based load balancing for images farm Result The NetScaler reduced server connection load by up to 90% (up to 10:1 client-server connection ratio). By reducing the server connection load, and providing increased connection load support, NetScaler has eliminated network outages and server outages. * * * Used ixChariot to simulate various applications. Used average response time improvement across 200 users of each application, simulating complete end-to-end transaction e.g. SAP ERP module, simulating placing an order: open account, add purchase, save, close, open again, edit, save again, over a T-1 / E-1 link. Orbital decreases your deployment costs by 70% over non-transparent tunnel or overlay solutions Reconfiguring security policies, firewalls, NAT, router QoS, and more Non-transparent solutions can increase operational costs by 75% Approximately 25% of networking budget is for monitoring and management of existing TCP/IP flows * This slide largely covers the differences between App Firewall and IPS/IDS systems. * * Complex Web Applications Require LearningEnhancing positive security model to prevent false positives * * 应用加速需要在一个端到端的过程中优化所有的环节来共同达成目标，我们将它分为2部分来考虑，第一部分是内容生成的时间，以及大小的问题，内容生成越是快，生成的内容越是小那传输量和效率就能提高，第二个问题就是传输，如果传输过程中能有更高的效率以及更智能的协议基础，那么传输的效率必定大大提高。 下面，我们将从压缩缓存这2个功能来介绍如何减少内容生成的大小与时间，通过介绍TCP协议优化技术，SACK，RFC1323的功能来介绍如何优化网络传输的效能。 * There are 2 builds within this slide – click 2 times.
