The NetScaler SD-WAN release version 10.0 introduces the following new features and enhancements:
Support for classification of HTML5 receiver, and Adaptive Transport HDX traffic is added. When classified, these applications can be used in application rules, and to view application statistics.
You can create custom applications and enable reporting for them. Reporting statistics for the user created custom applications can be viewed and filtered in NetScaler SD-WAN Center.
NetScaler SD-WAN 10.0 allows the network administrator to upgrade the software on the sites in the network selectively, without needing to upgrade all sites simultaneously. A specific use-case for this feature is an administrator who wants to test the new software on few branch sites before installing it on all sites in the network.
You can configure a site as the secondary / geo MCN to support MCN redundancy. The secondary / geo MCN continuously monitors the health of the primary MCN. When the primary MCN fails, the secondary / geo MCN assumes the role of the MCN. In NetScaler SD-WAN 10.0, you can create a secondary MCN easily by cloning the primary MCN.
Multi-region deployment uses Regional Control Nodes (RCN) to control the client sites in a geographical or administrative region. You can also clone the RCN to create a secondary / geo RCN.
Scalability is achieved by defining regions and managing regions using the Region Controller Nodes (RCN). The MCN manages the RCNs in the network and the RCN manages the client sites in its region, allowing the user to centrally manage large scale Enterprise / MSP deployments.
Path mapping and bandwidth usage enhancements are implemented. Based on the incoming traffic bandwidth demand, the traffic is processed in load balanced transmission mode, duplicate transmit mode, or persistent path transmit mode. You can monitor the path information for traffic flows in Monitoring > Flows, under Paths column. You can also hover your mouse cursor over any flow to view the DPI application name.
- In the new centralized license model, an administrator can manage licensing from a central licensing server without having to access the appliance in the network. You can configure the IP address of a remote server as the licensing server and select the configuration to the appliances in the network.
- NetScaler SD-WAN Center can be configured as the licensing server.
Support for BGP route refresh as per RFC 2918 to assist non-disruptive route-policy changes is added.
Support for Enterprise/MSP to Scale 64 K Route table for all appliances:
The number of routes supported on all appliances is scaled from 16000 to 64000.
Route summarization reduces the number of routes that a router must maintain. A summary route is a single route that is used to represent multiple routes. In NetScaler SD-WAN 10.0, you can configure a summary route by using Local and Discard service types. The summary route is advertised to the peer SD-WAN appliances as the only route that encompasses all subnets falling as part of the summary route instead of sharing all subnet routes.
An administrator can decide which data center can be the most preferred by influencing route costs based on the new Virtual Path Route Cost feature.
- Virtual path route cost: You can configure Virtual Path route cost for individual virtual paths that are added to the route cost when a route is learnt from a remote site. With the introduction of VP route cost, the WAN to WAN forwarding cost is deprecated, because VP route cost helps influence the decision henceforth.
- OSPF route cost: You can now import OSPF route cost (type1 metric) by enabling “Copy OSPF Route Cost” in import filters. OSPF Route cost is considered in route selection instead of SD-WAN cost. Cost up to 65534 instead of 15 is supported, but it is advisable to accommodate for appropriate virtual path route cost that is added when route is learnt from a remote site.
- BGP - Copy VP Route cost to MED: You can now copy Virtual Path route cost for SD-WAN routes into BGP MED values when exporting (redistributing) SD-WAN routes to BGP peers. This can be set for individual neighbors by creating a BGP policy and applying it in the “OUT” direction for each neighbor.
You can now create multiple import or export filter templates by using various filter rules and associate the template at each site. The user created site level import/export filter rules take more precedence. The template rules follow the user created rules when associated to the site in Route learning section of Connections.
You can view additional information related to dynamic routing and the protocol status. Type the following command and syntax to access routing daemon and view the list of commands.
This is a restricted CLI access for debugging routes.
VRRP provides device redundancy to eliminate the single point of failure inherent in the static default-routed environment. VRRP ensures a high availability default path without configuring dynamic routing or router discovery protocols on every end-host. NetScaler SD-WAN 10.0 supports VRRP version 2 and version 3 to inter-operate by using any third party routers. VRRP cannot be used between two NetScaler SD-WAN appliances. It can be used between NetScaler SD-WAN appliance and the peer routers that are standard VRRP RFC compliant routers.
You can create application routes using application objects. This application routes aids in steering the traffic based on DPI or IP infrastructure using various SD-WAN services, such as Virtual Path, Internet, Intranet, Local, GRE, or IPsec.
By using static multicast group, network administrators can control the source and destination of the multicast traffic. In NetScaler SD-WAN 10.0, users can statically configure multicast groups and enable IGMP Proxy for updating the upstream code networks by using all the sources in the downstream networks of the edge
NetScaler SD-WAN Center
A hierarchical tiered network architecture is introduced to enable higher scale, and delegation of regional administration in NetScaler SD-WAN 10.0. NetScaler SD-WAN Center supports multi-region mode deployment, RCN discovery, and SD-WAN collector configuration and software upgrade.
- The NetScaler SD-WAN center 10.0 dashboard includes a multi-region summary dashboard. This dashboard provides a graphical overview of the network health at the various regions.
- You can view the network maps in either the tile view or the schematic view.
You can now configure NetScaler SD-WAN Center to act as the remote license server for centralized license management.
Support added for 10G Virtual Ethernet interfaces on the SD-WAN VPX-SE/VPXL-SE appliances in the VMware ESXi deployment. You can enable this feature by changing the driver for the virtual NIC from E1000 when deploying and configuring SD-WAN VPX-SE/VPXL-SE platforms using VMware ESXi.
Support for 1Gbps throughput for SD-WAN Standard Edition platforms deployed on Hyper-V is added.
Support for more ports for VPX-SE HA deployments between servers is added. This support would enable customers to map high availability interfaces one-to-one to real ports to avoid any hypervisor misconfiguration that would separate the virtual appliances and cause both virtual appliance to become active.
In release 10.0, the number of maximum network interfaces supported by the SD-WAN VPX-SE platforms is 8 unlike in previous release versions in which the number of network interfaces supported was only 4.
- A new NetScaler SD-WAN 2100 EE edition is introduced.
- Enhancement to current appliance configuration for REST APIs to include Site, WAN Link, Virtual Path, Firewall, Quality of Service, DPI, iPerf, and Management IP.
- Support for local user and group management REST APIs.
- Capability to update the NetScaler SD-WAN Appliance OS and License files using REST APIs.
- Enhance current monitoring REST APIs to include WAN Link, Virtual Path, Firewall, Quality of Service, Applications, and Flows.
- Introduced REST APIs for NetScaler SD-WAN Center.
