Allow retrieval of VLAN tag from packet-in match. The VLAN tag might be here if the switch popped the VLAN tag from the packet itself prior to encapsulating it in the packet-in message.

Add new detailed-match property to define source and destination addresses to match on in each layer. Also add in-port as an optional match for the existing match property.

Don't use statistics service to get link speed. This can be derived from the IOSwitchService more efficiently. Remove link speed function from IStatisticsService.

Change log levels of frequent, unnecessary logs to debug. Were previously warn. Add new RoutingManager to properties

Restrict access to TopologyInstance constructor and compute() functions. Other public functions should also be changed to private or protected.

Create RoutingManager that is separate from TopologyManger. It hooks into TopologyManager via new ITopologyManagerBackend, butmakes it much more obvious that the TopologyManger and TopologyInstance is responsible for much of the routing. Before this change, the actual 'routing' and 'path-finding' implementation location wasn't very clear.

More REST API updates. Added JsonObjectWrapper class to wrap types that Jackson will serialize into arrays (illegal if outer type in JSON).

compute() has been optimized and all old code is gone. We no longer need to compute trees for each cluster. Furthermore, the computation of broadcast ports has been streamlined. Other routing/topology refactoring has been done as well.

Next round of refactoring. Attempting to normalize the terminology used. Fixed some bugs that have been around for a while too.

unit tests fixed by fixing an archipelago bug. A cluster is a *strongly connected* group of switches. A switch that is weakly connected to a cluster but not strongly connected to any other cluster will exist in its own cluster. This weak link, if not an external/BDDP-discovered link, will not be used to try and compute paths. Thus, while we compute clusters, any link that is not within a cluster and is not an external link is stored for reference when computing archipelagos. Essentially, the external links which typically are between clusters get merged into a new set with these weak links to allow for proper computation of archipelagos.

Changed ArrayList<> types to ImmutableList<> where applicable. OpenFlow messages are now cached in Forwarding.deleteFlowsByDescriptor().

Create wrapper class that takes an OFMessage and allows for direct use in other containers where we don't care about the XID of the message. For example, if we want to create a unit test with predictable results but the XIDs are different depending on unit test execution, we can use the wrapper class to guarantee consistency. In the main code, we can more easily compare OFMessages without care for the XID and create cool data structures like caches.

Put maximumRouteEntriesStored into floodlightdefault.properties. Topology manager and instance can now access it.
