12. 12 Benefits of Deploying LinkEasy Service Provider Edition (cont.) Solve traffic loading problem for authentication and metering system put in centre of the network –In such a centralized approach, all Internet traffic will go through that system at the network centre –It poses traffic loading problem when number of broadband users at the network edge increases –Failure of any centralized system will result in service interruption to all users –The BRAS also has its capacity limitation for upgrade –Distributed authentication and metering is more desirable to avoid aggregated loading to the system in the network centre –LinkEasy distributed architecture allows add-on-demand to achieve a highly scalable solution

14. 14 Deployment Scenarios of LinkEasy Solution for Telco/ISP (Scenario 1) The benefits of this deployment for Telecom Carrier are –The account administrative functions of LE-2000 can be kept within the LAN, thus it will not be affected even if the WAN link is congested or disconnected –For VLAN configuration, deploying LE-2000 in Hotel/Property premises would allow flexible control and ease of management by Service Provider –Our patented QoS feature can intelligently define and prioritize the WAN Link traffic, which is commonly the bottleneck for downstream and upstream access. E.g. if 100 active users connected to a 10Mbps Ethernet WAN Link, each active user at most can use 100kbps for data transmission. If the traffic priority cannot be policed, users have to contend for the limited bandwidth resources, as a result, all users are suffered. –It allows user with higher priority can have bandwidth guaranteed for both upstream and downstream data transmission so that true broadband performance is delivered.
