ABSTRACT:
A router (101, 103, 105) includes a communication interface, for receiving a packet (107a-107f), when connected to a communication network. The router (101, 103, 105), for example with a processor, for calculating an alternate path for routing a packet (107a-107f) received from the communication interface while awaiting a determination that a pre-determined path for the packet has failed. According to one or more embodiments, the router (101, 103, 105) can facilitate calculating an alternate path for routing the packet (107a-107f) received from the communication interface while awaiting a first determination that a pre-determined path for the packet has failed and/or a second determination that the pre-determined path is likely to fail. Further in accordance with one or more embodiments, the router (101, 103, 105) can predict a behavior of network element(s) in a route topology, wherein the network element(s) is included in a pre-determined path for routing the packet received from the communication interface.
