tserver

Testbed server runs a customized version of standard xinu operating system on BBBs which is responsible for two main tasks:

• Uses Control Protocol to accept commands from the Management application. The management application commands allows the testbed server to setup, control and manage a set of nodes for an emulation scenario. Management application sends message associated with each command over UDP on port 55000 using Control Protocol.
• Uses Server to node protocol to communicate with the nodes over Ethernet. This type of communication is required to satisfy the following requirements:
  • The testbed server requires to communicate with the nodes to provide appropriate responses for a subset of management application commands such as nping, xon, xoff, pingall.
  • The testbed server requires to communicate with the nodes to accept and process join requests and assign multicast address and ID to each of the nodes.
  • The testbed server requires to communicate with the nodes to update the multicast address for the affected nodes when it receives newtop command.
