Abstract: Techniques whereby a LAN-side border router observes all packets of an application flow from both directions so that the application recognition performed on the LAN-side border router functions properly. A border router may implement flags in a flow cache to indicate whether the border router is the LAN-side border router and/or a WAN-side border router for an application flow. As packets are received at a border router at either the LAN interface or WAN interface, the flags associated with packet's application flows are examined to determine if the border router is the LAN-side border router for the application flow. If so, then application recognition and routing control may be performed. If not, the packet may be redirected to another border router that may be the LAN-side border router or the WAN-side border router for the application flow to insure that border router observes the packet.

Abstract: According to the techniques presented herein, location data from signals transmitted by a plurality of mobile wireless devices in a wireless network are obtained. For each mobile wireless device, location data time points are aggregated to generate a plurality of routines or paths of movement for each mobile wireless device within a predefined space. The predefined space is partitioned into a plurality of units and each routine of the plurality of routines is also partitioned into a plurality of subroutines or segments. For each unit, one or more subroutines within a predefined distance of a frequent subroutine are combined with the frequent subroutine, and the frequent subroutines may be displayed on a graphical interface to visualize aggregate movement of the plurality of mobile wireless devices within the predefined space. Frequent subroutines may be analyzed in an automated manner to generate notifications and alerts.

Abstract: A software defined network controller detects when a host has moved between network elements in a network. The controller generates a list of network elements to which the host has roamed, the list being sorted by time when the host is attached to a network element so that a most recent network element to which the host is attached is the root network element and at a head of the list. The controller updates the root network element in the list first for traffic flow associated with the host. The controller sends commands to the network elements to program a tunnel from each previous point of attachment network element in the list to the most recent root network element in the list in reverse order of the roaming path so as to route traffic for the host via a tunnel.

Abstract: According to some embodiments, a method performed by a software defined wide area network (SD-WAN) controller in a SD-WAN network comprising a plurality of aggregation edge routers and a plurality of branch edge routers comprises the following steps. The method comprises: receiving, from each of the plurality of branch edge routers, a transmit location (TLOC) publication comprising a quality of service (QoS) attribute of one or more TLOCs configured on the branch edge router; determining a QoS policy based on the received TLOC publications; transmitting the QoS policy to the plurality of aggregation edge routers; receiving, from a branch edge router of the plurality of branch edge routers, a first congestion indication indicating that bandwidth utilization on a wide area network (WAN) interface of the branch edge router exceeds a first threshold; determining an updated QoS policy based on the received TLOC publications and the first congestion indication to reduce congestion at the branch edge router; and transmitting the updated QoS policy to the plurality of aggregation edge routers.
