Abstract: One aspect provides a system and method for selecting a path for a data flow in a network. During operation, a first node receiving the data flow can determine flow information that specifies a destination node. The system estimates a Quality of Experience (QoE) value of each node based on the flow information and current operating status of each node. A management service generates a QoE topology of the network based on connectivity among the nodes and the QoE value associated with each node; determines a plurality of potential paths between the first node and the destination node, with each potential path comprising a plurality of intermediate nodes; and selects a path that provides best QoE performance based on the QoE topology. Selecting the path comprises computing a cumulative QoE value of each potential path based on QoE values of the intermediate nodes included in the potential path.

Abstract: In implementations of the present disclosure, there is provided an approach for reducing unnecessary network down. A method comprises determining a plurality of virtual access points (VAPs) of the AP in a radio frequency (RF) band. Then, the plurality of VAPs are divided into a plurality of VAP zones based on a set of data forwarding entities corresponding to overlay VAPs in the plurality of VAPs, and the plurality of VAP zones includes a bridge zone and one or more overlay zones. A VAP is selected from the bridge zone for allocation to an MBSSID group of a set of MBSSID groups for the plurality of VAPs as a transmitted VAP (TX-VAP). The TX-VAP is used to transmit a beacon frame for the MBSSID group. Implementations of the present disclosure can help the AP to reduce unnecessary network down caused by data tunnel broken and limit the negative network impact.

Abstract: A first switch port receives a first control packet, a header having a source media access control (MAC) address of a first MAC of a first interface of a sending device and a payload containing a second MAC of a second interface of the same sending device. The first and second interfaces form a bonded interface for failover purposes on the sending device. A second switch port receives a second control packet, a header having the second MAC as its source MAC and a payload containing the first MAC. The switch associates the first and second MAC addresses as related MAC addresses associated with the bonded interface. The switch facilitates failover between the secure interfaces via multiple uplinks while maintaining the port security on the switch by allowing transmission of data from either the first or second MAC address, associated as related MAC addresses, without triggering a port security violation.

Abstract: Systems are methods are provided for implementing load balancing of IPsec security associations (SAs) SAs between different heterogeneous cores, for example in a multiple controller systems. The balancing of IPsec SAs are performed using software implementations of IPsec offloading and/or hardware implementations of IPsec offloading. By balancing the processing functions related to orchestration of IPsec SAs between hardware (e.g., IPsec hardware accelerator) and software (e.g., IPsec software accelerator), the methods realize increased optimization, improved user experience, and enhanced product performance in networks using IPsec. For example, an IPsec session is initiated, and it is determined whether a resource limitation for a hardware-based IPsec accelerator has been reached. If the limitation for the hardware-based IPsec accelerator has been reached, processing for the IPsec SA for the initiated IPsec session is offloaded to a software-based IPsec accelerator.

Abstract: Example implementations relate to connecting an IoT device to a wireless network using Device Provisioning Protocol (DPP). An authentication server receives a DPP network access authorization request including a connector identifier from an Access Point (AP) in communication with the IoT device. The connector identifier is a hash of the public network access key of the IoT device. If the connector identifier is valid, the authentication server determines a configurable policy from a set of configurable policies that is applicable to the IoT device. The authentication server transmits network permissions defined in the configurable policy to the AP. The IoT device is connected to the wireless network by the AP based on the network permissions.
