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

•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

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.)

© 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

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

Link Redundancy

• LR Trigger for LACP channelsᵒ 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 channelsᵒ 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.

When one of the

active link fails, and

lrMinThroughput is

hit, we select a

subchannel with

make it active by

reseting all other

interfaces

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

Service Supporting Features

• Content Switchingᵒ Multi-port CS

• Configure a CS vserver on a combination of ports

ᵒ DNS_TCP Support• DNS_TCP protocol is now supported with a Content Switching Vserver

• Audit Loggingᵒ Ability to distinguish whether the command is executed from CLI or the GUI

• AAA Session Stickinessᵒ LDAP, RADIUS, & TACACS: We now stick to the server where last session was

successful.

© 2014 Citrix

Service Supporting Features (cont)

• AAA-TMᵒ Custom error strings

ᵒ Backend HTTP Web-Form Authentication

ᵒ Strong Encryption Support in KCD/Kerberos (AES-256, RC4-HMAC)

• OWA Force Session Timeoutᵒ Forced timeout on long-lived connections that are open for monitoring

• Client Certificate Pass-throughᵒ In XenMobile deployments, a client-certificate is required to be passed to Storefront.

Now send the client-certificate any Application server. No configuration needed.

• Forms Based SSO – Relative URLsᵒ NS can take relative URL and processed for Form based SSO

SDX SVM Manageability & 3rd Party Software

• CLI Support

• File management via NITRO

• AAA Supportᵒ Use LDAP/TACACS/RADIUS for

SVM accessᵒ Authorization & Audit log supportᵒ Password expiration supportᵒ For more details refer : AAA edocs

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

© 2014 Citrix

SSL

• ECC Cipher Supportᵒ 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 Profilesᵒ SSL profiles added for frontend and backend communication

• SSL Cert Chainᵒ Helps identify the certificates belonging to a chain and suggest if a cert is

missing in the chain.
