TopologyModes of Operation Uplink Connection

7

VPN Handover Mode

Applications: Condition Based Maintenence, Operative Systems, AFC-systems

=> Increase coverage and service availability

One uplink with VPN (IPSEC) used at a time

All available uplinks are in standby with VPN open

Immediate and transparent handover with connection persistence

Connections managed based on link availability, response time,and performance

Dynamic Load Balancing Mode

Application: Passenger WiFi Service, PIS, Video Surveillance

=> Increase bandwidth and coverage

Load balancing on uplink and downlink

All links are used together to increase bandwidth (not speed)

Traffic dynamically allocated to available uplinks


9/19

OverviewWhat is Load Balanced Link Bonding?

8

Combining multiple 3G/EDGE up-links into one single high capacity connection

Load balancing and bonding on both up- and down-link

Uplinks qualified dynamically to determine optimal balancing

Network sees only one single connection

Each uplink has its own VPN for traffic

Packets distributed dynamically to all uplink VPNs based on intelligent algorithm

Back-end Gateway Server combines distributed packets together

Router takes advantage ofmaximal available cellular capacity at all times

Link loss will cause packets to be distributed to remaining available links

Continuous connection and session persistence

Network CoverageHow Many Uplinks are Needed?

9

Achieved data capacities 2-5Mbit/sdownstream and 0,5-1 Mbit/s upstream(HSPA+ service)

Total Time 3347s

No Internet Connection Available 1s

Internet Connection 3346s (100%)

Good communication on all 3G Uplinks 2397s No communication available Operator 1 83s
