Open Network Lab Concept

• Several gigabit routers with FPXs SPCs.
• PCs serve as hosts.
• half on shared subnets
• 160 Gb/s ATM switch.
• link routers in virtual topologies
• traffic generation
• programmable delay
• Tools for configuration and collecting results.
• web forms and/or GUI
• monitoring traffic
• data capture and playback
• Build open-source development culture

Starting New Project
default screen for new project
available routers with fixed CPs and GigE subnets
available and assignable hosts
spin handle

Defining Links
add links with wiring tool with bendable
links
support group/ ungroup feature
maintain links when objects are dragged

Configuring Routes Filters
right-click on port for port properties
route table priority level, editable field
link props. ? route table ? in flow table ? out
flow table ? in filter table ? out filter
table ? port traffic ?
similar tables for flows (aka exact match
filters) and filters (aka general filters)
add/delete/edit routes directly, scroll to access
other fields

  next hop(s), traffic counters, ???
• show/hide feature displays end-to-end flow path
  on GUI
• provide tool for graphical entry of flow table
  entries
• Filter tables (in and out)
• similar to above but show address and port number
  ranges, wild-cards, etc
• Plugins
