This module is part of the nmeta suite running on top of Ryu SDN controller to provide network identity and flow (traffic classification) metadata

class tc_static.StaticInspect(config)

Bases: baseclass.BaseClass

This class is instantiated by tc_policy.py (class: TrafficClassificationPolicy) and provides methods to query static traffic classification matches

check_static(condition, pkt)

Passed condition and flows packet objects Update the condition match with boolean of result of match checks

is_match_ethertype(value_to_check1, value_to_check2)

Passed a two prospective EtherTypes and check to see if they are the same. Return 1 for both the same EtherType and 0 for different Values can be hex or decimal and are 2 bytes in length

is_match_ip_space(ip_addr, ip_space)

Passed an IP address and an IP address space and check if the IP address belongs to the IP address space. If it does return 1 otherwise return 0
