3.1.6 Port Management

• On a widely-shared network such as PlanetLab, port management is an issue
• All slices share the same port space
• Ports below 1024 are restricted/reserved
• There is currently no administrative restriction on port usage
• There is currently no automated port reservation mechanism
• This will change in the future, for now to reserve a port, we use the wiki...
• Don't simply make the assumption that large port numbers are less likely to be occupied
