- 11. © 2014 Citrix How NetScaler Optimizes The Front-End • Change embedded URLs to use sub-domains and trick the browser to open more connections Domain Sharding • Remove unnecessary characters & space • Simplify processing & reduce download time to client device • Move CSS & JS objects to end of HTML body • Inline Download Minimize & Optimize Order of CSS & JS • JPG optimize, Convert GIF to PNG, Image Lazy load, Image shrink to display attributes of the user-device Image Optimization
- 12. Core
- 13. © 2014 Citrix •1000s of Views now only in HTML5 •Load time reduced by over 50% •Improved user efficiency •Following areas will be converted in a 10.5 maintenance release •AppFW, Visualizer, Diagnostics Conversion from Java to HTML5
- 14. © 2014 Citrix Core Feature Watch This • Policy Variables ᵒ Store a token (data) from the request or response in a system variable ᵒ Reference stored data for • Fully customized session persistence • Internal computation • Policy processing
- 15. © 2014 Citrix LLDP Support • Allow stations attached to an IEEE 802 LAN to advertise System Information. Helps to create network topology. • System information advertised ᵒ Capabilities ᵒ Management addresses ᵒ Connectivity information Dst MAC 01-80-C2-00-00-0E Src MAC Ether Type 88-CC LLDP Info LLDP Info consist of multiple TLVs TLVs must be in following sequence

- 17. © 2014 Citrix What is Admin Partition? • Logical separation of NetScaler into multiple units • Functions like an independent Netscaler. • Provides isolation of configuration and data/traffic • Provides multi-tenancy, but without separation of system resources, like., CPU, Memory, etc. • Consists of Application resources (services, vservers, policies, monitors, etc.)
- 18. © 2014 Citrix Highlights of Admin Partition (Contd…) • Separate GUI/CLI/Monitoring/Report • IP overlapping • External Auth - AAA • No inter partition routing • No read/write access to others • Overall System security • HA – Connection Mirror
- 19. © 2014 Citrix Partition Definition • System admin defines partition • Associates partition admins • Defines IP space for partition • Vlan and other Network config Partition Admin • Defines the App • Service creation • Vserver creation • Policies/Profiles • Access common resources • Creates SNIPs • Networking resources System Expectation • Config file • Sh run • Save config • Clear config • SSL cert/keys Manageability Expectation • Config UI • Reporting • Dashboard • SNMP • AppFlow/Insight Admin Partition Workflow

- 28. © 2014 Citrix Link Redundancy • LR Trigger for LACP channels ᵒ Set a minimum bandwidth for dynamic channels. When throughput falls below threshold, a link failover is triggered to make another channel. ᵒ For HA pair, when all channels reach threshold, trigger HA failover. • LR Trigger for generic channels ᵒ Fail to another channel (to a redundant switch) when threshold reached One of the active link fails – Min threshold is hit How it works? Key 1 Key 2 Key 3 At any point of time only one channel will be active. Switch X Switch Y Switch Z When one of the active link fails, and lrMinThroughput is hit, we select a subchannel with high throughout and make it active by reseting all other interfaces LCAP Key 4 Key 1 Key 2 Key 3 Switch X Switch Y Switch Z LCAP Key 4
- 29. © 2014 Citrix Orchestration • NITRO API SDK in Python for better server side scripting. Python SDK will be available and supported with python 2.7 and 3+.Python SDK • NITRO API support for routing protocols. Changes sync to all peers. Dynamic Routing • NITRO APIs for Upload, Download, Write and Read methods. Key functional requirements like SSL certkey will be able to get the benefits. File Operations • NITRO APIs and commands for better system manageability • Tech Support, batch, source, show nstrace, start nstrace, stop nstrace Other Commands

- 34. © 2014 Citrix TM & DNS LB: Increased number of service groups to 8000 DNS LB: CNAME record caching in Proxy mode • NetScaler to use DNS caching module to cache CNAME record and send it from NS than fetching it every time DNS: NAPTR • NAPTR support on NS along with SRV records. GSLB: Static proximity sync • Auto sync of static proximity db
- 35. © 2014 Citrix SSL • ECC Cipher Support ᵒ More secure & faster ciphers available on N3-based MPX, SDX, & VPX • ECDHE-RSA-RC4-SHA, ECDHE-RSA-DES-CBC3-SHA, ECDHE-RSA-AES128-SHA, ECDHE-RSA-AES256-SHA • Common Name Check • Server Auth configuration is enhanced to accept “commonName” check. This check will be performed on SSL certificates received from backend server • SSL Profiles ᵒ SSL profiles added for frontend and backend communication • SSL Cert Chain ᵒ Helps identify the certificates belonging to a chain and suggest if a cert is missing in the chain.
