When drawing connectors, avoid using arrowheads:

• there are many properties to depict (who initiates connection/who makes requests/who sends most of data)
• readers tend to assume they know which property you represent but they can guess wrong

Instead:

• use typographic differences on ports and connectors
  • put them in the legend (Put legend on diagrams)
• list properties textually
