Networking Overview
Live notes may be taken for this topic at: http://etherpad.openstack.org/Networking
Nova Implementation
Current implementation
- Private networking and VPNs
- Instances attached to separated VLAN tagged bridges
- IP Address allocation handled by API
- DHCP Server assigns addresses
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
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, service-net, management-net
- Management-net is used for communication from controllers to host.
- Instances connected to single bridge for each network, public, service-net
- Bandwidth throttling.
Future implementation
- Addition of host-net bridge for internal communication from Instances.
- Needed for Hypervisor agnostic communication for Guest Communication. (we can't rely only on XenStore)
- IPs assigned via DHCP over local host network.
- Is this an additional guest network interface or does this piggy back existing?
- Open vSwitch
- Instance protection rules could be pushed into the vSwitch.
IPv6
IPv6 should have first-class support, we can derive IPv4 address binding with the IPv6 to IPv6 mapping space and configuration options.
