Nomad provides a number of advanced features that require changes to the default configuration of Nomad client.

These features are described in greater detail in the following pages:

Peer copy over HTTP or HTTPS

Nomad peer copy uses SMB by default, which requires File and Print services to be enabled in order for it to share the content. From version 4, you could bypass these services and use the connectionless transfer protocol over the User Datagram Protocol (UDP) instead. However, this implementation was not scalable and fully secure. To overcome this limitation, peer-to-peer copy over HTTP is available from version 6.2 where each Nomad client acts as an HTTP server and can serve content from its cache. The election process determines the master and instead of copying content from its file share via SMB, peers looking to download content make HTTP requests to the master.

Full control over WAN link usage

Nomad dynamically analyzes the overall WAN traffic to ensure that it only uses a percentage of the total. It is also aware of mobile devices and knows the difference between wireless and wired connections and is able to select the most efficient available connection to use.

Nomad FanOut

Windows imposes a limit on the number of concurrent connections on the Nomad share. The  FanOut feature  compensates for this limitation by enabling peers connected to the master to themselves allow connections to other peers requiring the download so that more peers can be updated at the same time.

IPv6 and DirectAccess support

By providing support for IPv6 environments, Nomad supports distribution to clients connected to the corporate network using the DirectAccess feature.

Managing large package distribution with multicast

If you want to make more efficient use of your network when distributing the same data to many devices, you may want to consider using multicast – it may already be used in your environment for multi-media tasks such as providing video content. Multicast is a complex technology that requires complete buy-in from both your system and network administrators.

FIPS compliant communication encryption

Nomad has always provided encryption for most of its communications and in Nomad 6.0 an advanced FIPS compliant encryption algorithm was made available. The United States Federal Information Processing Standard (FIPS) is a standard that defines security requirements for software used by the U.S. federal government. It stipulates that applications that encrypt any sensitive data should use only a certain set of approved encryption algorithms.

Nomad SECure

Nomad SECure enables content to be compressed and signed, and also encrypted on the DP which clients can download. If you intend to use this feature, you must update all Nomad clients to 6.1 or later, or they will fail to download encrypted content. This is because clients older than 6.1 only supports the original unencrypted data format.
