    Abstract: Techniques are described herein for service chaining in fabric networks such that hardware resources can be preserved without service nodes needing additional capabilities. The techniques may include storing a first configuration associated with a first VRF instance of a service forwarding node that is connected to a first service of a service chain sequence. The first configuration may indicate an identifier and a type associated with a second service of the service chain sequence where traffic is to be sent after the first service. Additionally, the techniques may also include storing a second configuration associated with a second VRF instance of the service forwarding node that is connected to the second service. The second configuration may indicate that the second service is a last service of the service chain sequence. When traffic is received at the service forwarding node, the service forwarding node can determine whether the traffic is pre-service traffic or post-service traffic.

    Abstract: Techniques are described herein for resolving conflicts in role statuses assigned to a customer edge device by multiple provider edge devices in communication with that customer edge device. In embodiments, such techniques may involve receiving information about a customer edge device in communication with the first provider edge device and storing, based on the information about the customer edge device, an indication of a first role status of the customer edge device. The techniques may further involve receiving, from at least one second provider edge device in communication with the customer edge device, an advertisement message that includes a second role status of the customer edge device, comparing the first role status to the second role status, and upon determining that the first role status does not match the second role status, updating the first role status of the customer edge device.

    Abstract: Various devices, systems, and methods are described herein that provide bi-directional, and even multi-directional airflow within fan systems. These fan systems can be utilized by devices such as datacenter switches to change from one direction of airflow (such as port side inlet) to another direction (such as port side exhaust). This can be done manually by having a multi-directional fan housed within an enclosure that provides access through a hatch door. The multi-directional fan can be removed and reoriented to a second direction, thus providing airflow with the same quality and pressure in multiple directions. Fan changes can also be automated through one or more interlocking rotational gears coupled to the fans within a housing, such that rotating one gear will rotate each of the fans within the housing, thus changing the direction of the airflow. By doing this, only one fan is needed to provide airflow in multiple directions.

    Abstract: Correcting for antennae spatial distortions in Radio Frequency (RF) localization may be provided. A plurality of actual locations associated with a plurality of Access Point (APs) may be received. Then a plurality of signal strengths associated with the plurality of APs may be received. Based on the plurality of signal strengths, a model may be created that models a plurality of inference errors respectively corresponding to the plurality of APs between a plurality of inferred locations respectively corresponding to the plurality of APs and the plurality of actual locations. The model may then be used in determining a location of a device.

    Abstract: Presented herein are techniques to facilitate providing slice attribute information to a user equipment (UE) for one or more slice types with which the user equipment is allowed to establish one or more session(s). In one example, a method may include obtaining, by a network element, a registration request for connection of a UE to a mobile network; performing an authentication for connection of the UE to the mobile network; and upon successful authentication, providing, by the network element, a registration response to the UE, wherein the registration response identifies one or more network slice types with which the UE is authorized to establish a session and the registration response identifies one of: attribute information for each of the one or more network slice types or network location information from which attribute information for each of the one or more network slice types is to be obtained.

    Abstract: In one embodiment, a first device in a network receives a quantum computing power metric indicative of a maximum available compute power of quantum computers. The first device receives, from a second device in the network, a listing of cryptographic suites available on the second device. The first device selects, based on the quantum computing power metric, a particular cryptographic suite from among the listing of cryptographic suites available on the second device. The first device sends, to the second device via the network, an indication that the particular cryptographic suite is to be used to encrypt and decrypt traffic exchanged between the first device and the second device.

    Abstract: Techniques herein facilitate a device address rotation management protocol that may be implemented for a wireless local area network (WLAN), which can be used to influence when wireless client devices or stations may rotate their Media Access Control (MAC) addresses, how to perform such rotations, and/or the like. In one example, a method may include providing, by an access point (AP), a first communication indicating that the AP supports a MAC address rotation management protocol; obtaining, by the AP, a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and transmitting, by the AP, a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information.
