2 VLD : VIAEDGE Load Director Key Advantages: Server Load Balancing for TCP/UDP based protocols. Server load balancing providing Layer-7 traffic management for all applications. High performance SSL decryption and reencryption for end-to-end security NAT based forwarding High performance direct routing,tun,nat Multiple session persistence modes to ensure session integrity Server health monitoring to detect and route around problem servers. Comprehensive traffic visualization for trend analysis and fault isolation. Unlimited content inspection of TCP and UDP protocols for greater application awareness. VIAEDGE load director is a powerful load balancer that grows with your traffic management needs. It is a cost-effective starting point for adding load balancing and resilience to your services. Server Load balancer (SLB) which is now known as simple early generation load balancer is being replaced by next generation load balancer which is termed as Application delivery controller (ADC). Intent of ADC is to have a single device that incorporates not just a core set of load-balancing capabilities but a comprehensive set of application performance and security services as well. Reliability & High Availability Health Monitoring VLD health monitors check the availability and correct operation of the services on the nodes, routing traffic away from nodes that have failed. A wide range of built-in health monitors and the ability to run custom health scripts means that any server failure including embedded error messages and failures of related services can be detected, raised to the attention of the administrator and worked around whenever possible. Improve Performance Improve performance with SSL offload, WAN offload and content compression, as well as sophisticated HTTP optimization, delivering dramatically faster responses and improved capacity. Create Resilient Services Create resilient services and monitor the health and performance of these services. Advanced health monitors find application problems and route traffic away from failing servers. Comprehensive visualization and detailed diagnostics help you understand site behaviour and resolve any problems rapidly.

3 Load Balancing and ROI Comprehensive load balancing VLD includes static and dynamic load balancing methods, including Dynamic Ratio, Least Connections, and Observed Load Balancing, which track dynamic performance levels of servers in a group. This ensures that the best resources are always selected for improved performance and scale. SSL acceleration and offload Every VLD device provides hardware-accelerated SSL encryption taking the burden of SSL off of the application servers. By accelerating setup and bulk encryption, organizations can migrate 100 percent of their communications to SSL using more secure ciphers with virtually no application performance penalty or bottlenecks. Load Balancing Methods: Round Robin Weighted Fastest Response Time Server Agents Weighted Least Connection Weighted Round Robin Destination Hash Scheduling Source Hash Scheduling High availability and transaction assurance VLD delivers sub-second system failover and comprehensive connection mirroring, resulting in a highly available solution regardless of system, server, or application failure. VLD can proactively inspect and respond to any server or application error. Content transformation VLD provides a comprehensive solution to offload many burdensome or repetitious functions onto a centralized and high-powered network device. SSL, compression, and many other VLD functions provide a complete content transformation gateway to redirect, insert, or holistically transform application content for effective and efficient application integration.

4 Salient Features of VIAEDGE Load Director Fast cache Intelligent caching functionality provides tremendous cost savings by offloading repetitive traffic from web and application servers, increasing server capacity up to 7x. It s also the only solution that offers multi-store caching to manage distinct cache repositories per application or department, delivering precise and intelligent control for priority applications. Application health monitoring VLD provides sophisticated monitors to check device, application, and content availability, including specialized monitors for many applications (including various application servers, SQL, SIP, LDAP, RADIUS, Diameter, XML/SOAP, RTSP, SASP, SMB, and many more), as well as customized monitors to check content and simulate application calls. Intelligent compression Compression accelerates application performance as much as 2x while reducing bandwidth utilization by up to 80 percent. VLD condenses HTTP traffic using industry-standard gzip and DEFLATE compression algorithms, reduces bandwidth consumption and user download times over slower/low bandwidth connections. This provides rich support for compressing a variety of file types, including HTTP, XML, JavaScript, J2EE applications, and many others. Flexible L7 QoS Rate Shaping You can ensure optimal application performance by allocating bandwidth for higher-priority applications, controlling traffic spikes, and prioritizing traffic based on any L4 or L7 parameter. Customized application attack filtering Full inspection and event-based policies deliver a greatly enhanced ability to search for, detect, and apply numerous rules to block known L7 attacks. VLD also applies secure application templates to block unknown attacks and attacks targeted at the business logic of the application. Additional layers of security protect against hackers, viruses, and worms, while enabling continuous service to legitimate traffic. Insulation from protocol attacks VLD provides Protocol Sanitization and a Full TCP Termination point that independently manages client and server-side connections, protecting all back-end systems and applications from malicious attacks. Cookie encryption Cookies and other tokens transparently distributed to legitimate users are encrypted. You gain superior security for all stateful applications (e-commerce, CRP, ERP, and other business-critical applications) and a higher level of user identity trust.
