Welcome to the utd_cs6390_fall2011 wiki!

Requirements

• A domain consists of one PCE and a number of routers
• Each domain has an AS number from 0-9 (max of 10)
• Each router in a domain has a router ID from 0-9 (max of 10/domain)
• Each network has a globally unique network number from 00-99

1. router sends route request (RREQ) to PCE
2. PCE calculates route
3. PCE sends route response (RRES) to router

• PCE maintains a interdomain forwarding table
• specifes, for each network, the next hop AS and the AS hop count to the network
• Obtaining domain sequence for given network
• PCE advertises reachability to networks in its own domain to neighbor PCEs
  • Specifies AS hop count and network numbers
• PCE receiving advertisement
  • Updates it interdomain forwarding table
  • Increments the AS hop count in the advertisement and forwards it to its own neighbors

Design

I quite like some of the design elements of base, for instance:

• An include directory with softlinks to include files
• The abstract wrappers, we could use them for things like Sockets, Files, Graphs, and so on...
• Other things...
