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.
-made Netscaler, SRX, F5 network elements as pluggable service
-added abstract load balancer device manager ExternaLoadBalancerDeviceManager
-made both F5 and Netscaler pluggable service to extend ExternaLoadBalancerDeviceManager
-added abstract firewall device manager ExternalFirewallDeviceManager
-made SRX pluugable service to extende ExternalFirewallDeviceManager
-added API's to configure and manage netscaler devices
- 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.
Added PortForwardingServiceProvider, StaticNatServiceProvider, rename
PasswordServiceProvider to UserDataServiceProvider(may rename to a better name
later).
Add related function for service providers.
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
TODO:
- Still leaving the provider columns in data_center schema as-is for CloudKit and BareMetal
- ExternalNetworkDeviceMgrImpl still needs to fix the dataCenter.setProviders calls and externalNetworkApplicance usage checks to see if zone has external networking.
-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
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.
- adding supprt for Netscaler VPX & MPX load blancers
- implemented for virtual networking
- works only with new fetched public IP, inline support is not added yet
more details will be added in the bug
