Introduce the concept of Ip Deployer. The IP deployer would be responible for
apply IP to the element. Most element's IP deployer is itself, but it can be
someone else if we want to implement inline mode in the future.
- Create Default physicalnetwork and add traffic types while creating a zone
- DeleteProvider should error out if there are networks using the provider.
- Other validations
- ListSupportedNetworkServiceProvidersCmd will now return Providers along with its element's services and boolean 'canEnableIndividualServices' that indicates if for this Provider services can be enabled/disabled
- add & update NetworkServiceProvider changed to take in the list of services to enable. While adding a provider, if list is null then all services supported by the element are enabled by default.
- ListNetworkServices enhanced to take in a provider name and returns services of that specific provider.
As DhcpElement/VirtualRouterElement/RedundantVirtualRouterElement is decided to
be the service provider of the physical network, this API should be called to
add a new element, with correlated network service provider ID.
Then e.g. ConfigureVirtualRouterElementCmd should be called to configure and
enable the element.
Added PortForwardingServiceProvider, StaticNatServiceProvider, rename
PasswordServiceProvider to UserDataServiceProvider(may rename to a better name
later).
Add related function for service providers.
DHCP range, domain name, etc. are the property of network, not virtual router
specific.
The focus of virtual router configuration would on separate enable/disable each
service it provided.
2)Re-apply all existing firewall rules as a part of implement call. TODO: Cleanup all existing rules from the backend (leave them in the DB) as a part of shutdown call
-Bringing add/delete/list of all external network devices under one unified API's (addNetworkDevice, deleteNetworkDevice, listNetworkDevice)
-Refactoring External network manager to work from both sets of API's add/delete/list NetworkDevice and add/delete/list External Firewall/LoadBalancer
Add configure command for these virtual router based elements. The commands
should be different for different elements.
The context of configuration would be added later.
In the past, the NetworkElement would cover almost all the functionality that
e.g. virtual router can cover: firewall, source NAT, static NAT, password,
VPN... So anyone want to implement the NetworkElement would have to implement
these service's specific methods, even it wouldn't support it. Also, if we want
to find a e.g. FirewallServiceProvider, we have to proceed all the current
network service providers, to call a method to know if it support such service.
That's neither elegant nor scaling way to do it.
As the first step, this patch separates each ServiceProvider from NetworkElement
(there are some interface already out of NetworkElement, so this patch slightly
modifies them too), and only the class would implement the correlated interface, would
have the ability to do these services.
1) On enableStaticNat command we actually send the command to the backend (we used to just upgrade the DB in the past). The backend command carries sourceIp and destIp, and creates IP to IP mapping on the domR.
2) On disableStaticNat for the Ip address in addition to cleaning up port ranges, we also delete IP to IP mapping on the domR.
* API requires network id to be passed in (it was optional before)
* restartNetwork calls restart() method of all network elements in the system, and it's up to the element to decide which actions to take on the restart (for example, for Virtual Router it's IPAssoc/applyPF/applyLBRules).
status 6689: resolved fixed
Changes to destroyNetwork process. Here are the steps:
* shutdown network - shutdowns all network elements (domRs/Dhcps)
* delete network - destroy all network elements, cleanup network's resources (vlans, ip ranges), mark network with Destroyed state and set Removed field
