Rackspace Implementation
Current implementation
- Flat Network Design
- Networking configurations injected into instances, or pulled via a Guest Agent
- Instances protected by various IPTables, Ebtables, Arptables rules
- Protects instances from IP/MAC Address Spoofing
- Protects instances from ARP Poisoning Attacks
- Host machines connect three Datacenter Networks: Public, ServiceNet, ManagementNet
- ManagementNet is used for communication from controllers to host.
- Instances connected to single bridge for each network, Public, ServiceNet
- Bandwidth throttling.
Future implementation
- Addition of HostNet Bridge for internal communication from Instances to all host network for storage.
- Is this an additional network interface or does this piggy back existing.
- Need Hypervisor agnostic communication for Guest Communication.
- Open vSwitch
Nova Implementation
Current implementation
- private networking and vpns
- ip address allocation by api
- dhcp server
- instances attached to seperated tagged bridges
Future implementation
- pluggable network implementation
- support for flat networking model
- support for ip injection
- network is its own worker process and uses queue
- support for dedicated network hardware
IPv6
IPv6 should have first-class support, we can derive IPv4 address binding with the IPv6 to IPv6 mapping space and configuration options.
