The framework comprises a controller node
and multiple instances of compute nodes.
Each group has sub group controller node
and gateway node, in which the sub group controller node
is controller of subgroup and gateway node is controller among subgroups.
LTE promotes a flat architecture where base stations, or eNodeBs as they are called, are directly connected to a gateway node eliminating the need for a base station controller node
. Further, a standalone Mobility Management Entity (MME) has been defined dedicated to handle signaling traffic in LTE networks.
The controller node
sends a ReadProperty request message one by one in turn to all the other ([N.sub.m] - 1) master nodes.
Pricing starts at GBP5,500 per controller node
and GBP11,000 for a minimum two-controller configuration.
The following part explains the deployment steps on one controller node
and three compute nodes:
. The controller node
in server module includes GPC controller, Kalman state estimator, sender, and receiver as shown in Figure 5.
With a clustered network storage system the customer only has to add another controller node
, which costs far less than acquiring a whole new system, its associated software and additional maintenance charges.
