Network Topology - Client Perspective

  1. If the client uses normal grid communication, it connects to one of the routers. Only one router is required, but there may be several.
  2. If a client uses Java Web Start as a way to install, access to this port is needed.
  3. Clients that use one or more connection dispatchers need access to those ports.
  4. Connection dispatchers belong to applications deployed in the grid. Most applications have no connection dispatchers but they may have several. Therefore, the number of exposed connection dispatchers may be none or several.
