SGOS 6.x Features
64-Bit Operating System
The new 64-bit OS provides increased scalability and throughput for 64-bit platforms (SG810, SG8100, and SG9000s).
Flash Streaming Media Support (RTMP Proxy)
SGOS 6.1.1.x introduces streaming proxy support for the RTMP (Flash) family of protocols. Proxy support enables acceleration, monitoring, and control of Adobe Flash streaming media based traffic.
The RTMP proxy provides bandwidth usage optimization for live streaming traffic by splitting live streams. When a live stream is split, the ProxySG fetches the live stream once from the server and serves it from the appliance to all requesting clients.
Other supported features include the ability to monitor/control Flash streaming traffic handled by the ProxySG appliance and CDN inter-operability. If you have several ProxySG appliances, you can also define hosts and groups of hosts to which client requests can be redirected to create proxy chains. Those hosts can be servers or proxies. Define policy rules to redirect requests.
Configuring the RTMP proxy requires several steps. Consult the Online Help System from the Configuration > Proxy Settings > Streaming Proxies > Flash tab.
Asymmetric Route Detection and Handling
When reflect-client-ip is enabled, the ProxySG appliance is able to detect asymmetric routing for intercepted connections. New connections from the same source and destination IP pair are dynamically bypassed after asymmetric routing is detected (detection occurs on the first reset packet). The IP pairs are added to a table that contains the list of dynamically bypassed asymmetric routes.
SmartFilter Category Map 4 Support
SGOS 6.1.1 provides support for SmartFilter Category Map version 4. SGOS 5.5.x provided support up to version 3.
