Circus

A Circuit Simulator for SDN final project The goal is to implement a optical circuit switch simulator for testing the circuit language.

DESIGN SPEC

• For each switch

  • Basics

    • TCP connection to the controller
    • listen to a UDP port for data packets
    • forward data in the UDP port
    • maintain a list of outgoing port and incoming port
      • switch port: (ip:port)

  • SDN related

    • a table of existing flows (configured by controller)
      • in port : out port : lambda_in : lambda_out : time_slot

CONFIG FILE (to discuss)

/* controller config */ CONTROLLER_IP TCP_PORT NUM_SWITCHES

/* switch map */ SWITCH_ID IP_ADDR UDP_PORT ...

/* switch connection config --> every switch is cs switch */ SWITCH_ID CS_PORT_CNT PORT_CONN_1(SWITCH_ID) PORT_CONN_2 ...
