摘要： In one embodiment, a packet switching device is configured to operate as a spoke or a hub in a Dynamic Multipoint Virtual Private Network (DMVPN) using one or more initially negotiated service overlay capabilities including service encapsulation to use in communicating service overlay data packets between the packet switching device and another device (e.g., spoke, hub) of the DMVPN over an established tunnel (e.g., secure protocol channel). The packet switching device is further configured to negotiate updated one or more service overlay capabilities including updated service encapsulation to use in communicating service overlay data packets with another device (e.g., spoke, hub) without dropping the already established tunnel. In one embodiment, the negotiation between the packet switching device and another device (e.g., spoke, hub) of the DMVPN uses Next Hop Resolution Protocol (NHRP). In one embodiment, the service encapsulation uses Network Service Header (NSH).

摘要： In one embodiment, enhanced packet flow monitoring is performed by packet switching devices in a network. A packet switching device is configured to monitor a flow of packets passing through the packet switching device, including detecting a gap in consecutive packets of the flow of packets, and attributing the gap as not being dropped one or more packets based on a particular time duration between a last received packet of the flow of packets before said detected gap and a first received packet of the flow of packets after said detected gap. In one embodiment, the gap is attributed to not being dropped packets when the particular time duration is greater than a threshold value; and conversely, attributed to being dropped packets when the particular time duration is less than a same or different threshold value.
