New Software Features in Cisco IOS XE Release 3.16S
The following features are introduced in Cisco IOS Release 3.16S.
This feature provides a way for a device to put packets through a route map before routing them.
The route map determines which packets are routed to which device. You might enable policy-based routing (PBR) if you want some packets to be routed a way other than the obvious shortest path. PBR provides control over routing by extending and complementing the existing mechanisms provided by routing protocols. Possible applications for PBR are to provide equal access, protocol-sensitive routing, source-sensitive routing, routing based on interactive versus batch traffic, and routing based on dedicated links.

Circuit Emulation Service over UDP
Circuit Emulation Service over Packet-Switched Network (CESoPSN) and Structure-agnostic TDM over Packet (SAToP) are supported as a part of Circuit Emulation Service over UDP (CEMoUDP).
The feature is supported on 8T1/E1 interface module, 16T1/E1 interface module, and OC3 interface module on the router. Circuit Emulation Service over UDP is not supported for 32-port E1/T1 interface module (A900-IMA32D).

IP SLA - Service Performance Testing
This feature, Y.1564, is an Ethernet service activation test methodology, and is the standard for turning up, installing, and troubleshooting Ethernet and IP based services. Y.1564 is the only standard test methodology that allows a complete validation of Ethernet service-level agreements (SLAs) in a single test. Service performance testing is designed to measure the ability of a Device Under Test (DUT) or a network under test to properly forward traffic in different states.
