message_filter

message_filter

trema event handler filter utilities.

How this works?

• Rule based message filtering.
• filter passes values to rule, same as the "type".

  filter type: :packet_in, handler: :handle_lldp, rule: :lldp?

• filter calls message_handler when it receives a openflow message from the switch and filter rule returns true

Current Status

• This is not completely implemented.
• implement default handler rule.
• Testbed for topology manager.
• Testbed for slice manager.

Features

• Declarative Handler filter rule format DSL so that easy to read and debug by human beings.
