InterNetwork Roaming™
Many organizations have to rely on a combination of network technologies to get the coverage necessary for their mobile workers. A mobile worker may access enterprise resources after‐hours over a home Wi‐Fi network connected via DSL or a cable modem; travel to an office and use an Ethernet LAN; visit a customer site and connect via a WLAN for visitors; connect via a public hotspot at a coffee shop; and connect while traveling or out in the field using a carrier’s WWAN. Multiple WWANs from different cellular carriers are often needed to cover the entire service area.
Combining multiple networking technologies can be an effective way to effectively expand the footprint of a mobile network deployment, but the security challenges of each component must still be addressed individually. Each segment of the network may or may not have adequate security measures implemented to address its specific weaknesses. Sometimes it is not possible for an organization to physically manage and secure all of the external networks used for remote access. Therefore, it is especially important to have a single, reliable security framework in place that will secure communications both over the air and through the Internet, regardless of the network infrastructure being used.

Mobility XE's InterNetwork Roaming capability lets mobile workers change networks seamlessly, transparently and securely—without having to think about their network connections or needing to re-authenticate.
Mobility XE's InterNetwork Roaming is tightly integrated with network applications and single sign-on authentication so that users have application session persistance and do not have to re-login when they traverse networks, go in and out of network range, or suspend and resume their devices.
The Mobility XE server accomplishes this by establishing a virtual IP address for each VPN session. As users roam, enterprise application servers always see the same, unchanging virtual IP address rather than network-specific IP addresses. With Mobility XE, there is no need to re-segment networks, implement VLANs or deploy additional hardware to enable mobile workers to traverse networks seamlessly. They can focus on their work—not configuring, enabling and disabling adapters.
