Neighbor Aware Software Distribution › Overview

Overview

Neighbor Aware Software Distribution (NASD) is a CA ITCM feature that enables an agent to act as a Collaborating Agent for peer-enabled software Distribution. The Collaborating Agents are configured to retain the software packages that the Neighbor Aware Agents can download. Some agents in a subnet can be configured as Collaborating Agents which connect to the scalability server and can download the software package.

The NASD feature speeds up the software distribution as the collaborating agents can serve other agents even if the limit of maximum simultaneous executions on Scalability Server has been reached. If Scalability Server and agents are in different subnets, then the network bandwidth is reduced as the number of direct downloads from Scalability Server across subnets are reduced. As the Neighbor Aware Agents download the software package from the Collaborating Agents in a local subnet network, the software distribution is fast across the subnet.

Note:

  1. The NASD feature is supported only for agents which are configured for NOS-less download.
  2. The NASD feature is not supported for the agents that register with the Scalability Server using IPv6 address either in the pure IPv6 or Dual Environment. All agents that are registered with IPv6 address are treated as Normal Agents.
