NASD Implementation Scenario
Consider a Head office having the Domain Manager and the Scalability Server, and there are three branch offices, BO1, and BO2. The branch offices are spread across different geographic locations with each Branch office having around 100 machines.

Consider a Head office having the Domain Manager and the Scalability Server, and there are three branch offices, BO1, and BO2. The branch offices are spread across different geographic locations with each Branch office having around 100 machines.
Suppose if we want to deliver a patch to the branch office BO1. The Administrator performs the following steps for delivering the package:
- First, stage the package on Scalability Server.
- Identify two Agent machines to act as Collaborating Agents, Agent1 and Agent2.
- Enable the collaboration policy on the Scalability Server and couple of agents in the BO1.
- Deploy the package to the BO1.Initially the package will be downloaded to the Collaborating Agents Agent1, and Agent2.The remaining 98 neighboring agents will contact the two collaborative agents and download the package instead of the 98 agents connecting the Scalability Server at the Head office.
Thus, we are reducing the number of Scalability Servers in the network.
The administrator can add more number of Collaborating Agents depending on timelines at which the patch is required to be applied.
If there are 10 Collaborating Agents in the subnet, then initially five Collaborating Agents of the BO1 will connect to Scalability Server and download the package, as per the default policy. The remaining five collaborative agents will download the package from the earlier five collaborative agents which have already downloaded the package. And all the 10 collaborative agents will deliver the package to the remaining 90 agents. Thus increasing the number of Collaborating Agents speeds up the package delivery.
Earlier all the 100 agents used to connect over the WAN and download and install the package. And now with the Collaboration feature enabled, only two Collaborating Agents are connecting over the WAN to the Scalability Server at the Head office and remaining 98 agents are downloading the package from the above two Collaborating Agents. This saves the bandwidth and ensures a smart and rapid package delivery.
