Neutron Traffic Protection Support - API and Featurres

Background

1. A traffic storm occurs when a large amount of broadcast, multicast,or unknow unicast packets congest a network .

2. Some Mailcious programs maybe send a large amount of the particular type of traffic,eg ARP,ICMP...

Because the two points lead to exssive cpu and network cost, and some security problems, most physical switches offer many traffic protection functions,such as broadcast-suppression，storm control，arp anti-attack rate-limit. Neutron also need this ability in complex real-world data centers. 

traffic storm protection approaches:

Storm suppression, which enables to limit the size of monitored traffic passing through an Ethernet interface by setting a traffic threshold.When the traffic threshold is exceeded, the interface discards all exceeding traffic.

Storm control, which enables to shut down Ethernet interfaces or block traffic when monitored traffic exceeds the traffic threshold. It also enables an interface to send trap or log messages when monitored traffic reaches a certain traffic threshold, depending on the configuration.

Introduction

A proposal to allow the users of neutrn network service to get tranffic-protection in complex real-world data centers.

1.Per network: all the VMs/hosts on particular network belonging to a particular tenant get traffic-protection

2.Per port:A VMs/host connected to that port get traffic-protection

Concept

Attribute Type Required CRUD Default Value Validation Constraints Notes
id uuid-str N/A R generated N/A UUID for traffic-protection
name String No CR None N/A Human-readable name for traffic-protection.Might not be unique.
traffic_protection_policies dict No R Empty List N/A the description of policies about to which particular type of traffic, use which methos to achieve the traffic-protection.
tenant_id uuid-str No CR N/A N/A owner of traffic-protection

Traffic-protection-policies

traffic_type enum Yes CR none one of support type list which particular type of traffic
method enum Yes CR none one of support method list which method to achieve the traffic-protection.
args dict No CR empty dict N/A the arguments of traffic-protection method
traffic_protection_id uuid-str No CR N/A N/A which traffic_protection is associated with the policy
