Chapter 16. Managing Networks and Traffic

9.Click Add guest network.

The Add guest network window is displayed.

10.Specify the following:

•Name: The name of the network. This will be visible to the user.

•Description: The short description of the network that can be displayed to users.

•VLAN ID: The unique ID of the VLAN.

•Secondary Isolated VLAN ID: The unique ID of the Secondary Isolated VLAN.

For the description on Secondary Isolated VLAN, see Section 16.25.1, “About Private VLAN”.

•Scope: The available scopes are Domain, Account, Project, and All.

•Domain: Selecting Domain limits the scope of this guest network to the domain you specify. The network will not be available for other domains. If you select Subdomain Access, the guest network is available to all the sub domains within the selected domain.

•Account: The account for which the guest network is being created for. You must specify the domain the account belongs to.

•Project: The project for which the guest network is being created for. You must specify the domain the project belongs to.

•All: The guest network is available for all the domains, account, projects within the selected zone.

•Network Offering: If the administrator has configured multiple network offerings, select the one you want to use for this network.

•Gateway: The gateway that the guests should use.

•Netmask: The netmask in use on the subnet the guests will use.

•IP Range: A range of IP addresses that are accessible from the Internet and are assigned to the guest VMs.

•Network Domain: A custom DNS suffix at the level of a network. If you want to assign a special domain name to the guest VM network, specify a DNS suffix.

16.26. About Inter-VLAN Routing

Inter-VLAN Routing is the capability to route network traffic between VLANs. This feature enables you to build Virtual Private Clouds (VPC), an isolated segment of your cloud, that can hold multi-tier applications. These tiers are deployed on different VLANs that can communicate with each other. You provision VLANs to the tiers your create, and VMs can be deployed on different tiers. The VLANs are connected to a virtual router, which facilitates communication between the VMs. In effect, you can segment VMs by means of VLANs into different networks that can host multi-tier applications, such as Web, Application, or Database. Such segmentation by means of VLANs logically separate application VMs for higher security and lower broadcasts, while remaining physically connected to the same device.

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
