Cisco Solves Satellite/VoIP Bandwidth Issues with New Multiplexing Solution

[Satellite TODAY 04-10-12] Cisco is introducing an IP multiplexing technology for its Cisco Mobile Ready Net package that aims to dramatically improve the number of IP-based calls on a satellite link, the company announced April 9.

   Cisco Mobile Ready Net is used by military and commercial customers that need to quickly set up a network. Voice-over-IP and satellite links can create bandwidth issues, but Cisco said it came up with the new IP multiplexing capability to tackles the problem.
   Features have been added to update the operating system used in the 5915 ESR and the 5940 ESR to deliver up to a 20 to 1 increase in call volume capability, according to Cisco Product Manager Ken Kauffmann.

   “This allows you to have more phone calls, but also allows other applications to make use of additional packets per seconds,” Kauffmann said in a statement. “Customers are typically using satellite modems for uplink and downlink measured at 1800 to 2000 packets-per-second. It’s not something that’s efficient for VoIP traffic and using IPSec encryption for security will almost double the size of the traffic.”
