In addition to these datamodels, it also implements several RPCs for accessing interface operational data. Details of these datamodels and RPCs are described in following sections. Interface Manager also uses ODL Inventory and Topology datastores to retrive southbound configurations and events. As described above Interface Manager uses other Genius modules for its operations. It mainly interacts with following other modules-

Introducing Egress Service Binding

Currently Interface Manager supports service binding on port ingress only. However, there are services that need packet processing on the egress, before sending the packet out to particular port/interface. To accommodate this, interface manager will be enhanced to support egress service binding also. This will be achieved by introducing a new “egress dispatcher table” at the egress of packet pipeline before the interface egress groups.

On different application request, Interface Manager returns the egress actions for interfaces. Service modules program use these actions to send the packet to particular interface. Generally, these egress actions include sending packet out to port or appropriate interface egress group. With the inclusion of the egress dispatcher table the egress actions for the services would be to
