Summary
• Mobile Router allows for Networks in Motion™ enabling internet
connections from many types of mobile platforms.
• Users are mobile unaware – no need for special client software
• Layer 3 Routing (works with any communication link – wireless
or wired)
• MR is set and forget – no manual reconfiguration required as
MR moves between networks
• Users / Network retains its identity (keeps its address)
• Continuous connectivity and smooth handoffs between
networks
• Enables sharing of network infrastructure
• Rapid Deployment
• Securable
• Preferred path can be set by bandwidth or priority
• Dual Hot-Standby of HA, MR or FAs for redundancy
