Abstract: A system for enforcement of a set of segmentation policies at a gateway switch of a network is provided. Here, the segmentation policies can indicate which other roles are allowed to communicate with a respective role, which can indicate a set of privileges in the network. During operation, the switch can receive a first message associated with a join request for a multicast group from a host. The switch can also receive a second message comprising data from a source of the multicast group. The first and second messages can indicate first and second roles, respectively, of the host and source. Based on the first and second roles and a corresponding segmentation policy, the system can determine whether the host is allowed to receive the data from the source. If not allowed, the system can prevent the second message from being forwarded to the host from the gateway switch.

Abstract: A system for compacting traffic separation policies in campus networks, the system comprising an access layer switch and a campus border switch. The access layer switch is configured to receive a definition of one or more policies; responsive to receiving a packet, determine whether any of the policies apply to the packet; responsive to determining that none of the policies apply, cause a tag to be inserted into a communication header of the packet and forward the packet; and responsive to determining that one of the policies applies, forward or drop the packet according to the applicable policy and omit the tag. The campus border switch is configured to, responsive to receiving a packet from the access layer switch, determine whether the packet includes the tag, and responsive to determining that the packet includes the tag, apply a traffic separation policy associated with the tag to the packet.

Abstract: A system and a method for detecting and defending against adversarial attacks in decentralized learning models are described. The method comprises obtaining a learning parameter for determining a reference cryptographic hash value and a similarity between the data processing nodes (102). A cryptographic hash value is determined for each data processing node (102) based on the learning parameter. The trust score of each data processing node (102) is updated based on matching of the cryptographic hash value with the reference cryptographic hash value. The learning parameter of each data processing node (102) is merged to obtain a merged learning parameter based on the trust score. The merged learning parameter is provided to the data processing nodes (102) to be used for training the machine learning models.

Abstract: Examples described herein relate to mapping configuration objects of microservices in a cloud cluster. Examples include discovering isolated configuration objects of a microservice deployed in a cloud cluster, where relationships between the isolated configuration objects and a first package of the microservice is not visible. Examples include mapping the isolated configuration objects to a second package based on their metadata. After the mapping, the first and second packages are grouped into a configuration catalog, which includes complete configuration data of the microservice. Some examples include grouping configuration catalogs of multiple microservices into a library, which provides complete configuration data of an application composed of the multiple microservices. Some examples include grouping libraries of multiple applications into a parent library, which includes complete configuration data of a service composed of the multiple applications.

Abstract: Electronic device includes a drive carrier, a drive cage, and a backplane circuit board. The drive carrier includes a front structure, a first side structure having a keying protrusion, and a second side structure, which in conjunction receives a media drive such that a rear face of the front structure abuts a front face of the drive and the keying protrusion extends beyond a rear face of the drive. The drive cage includes a drive bay and a keying flange inside the drive bay. When the drive carrier is arranged in the drive bay in a first orientation, the keying protrusion aligns with the keying flange and prevents the drive to couple with the backplane circuit board. When the drive carrier is arranged in the drive bay in a second orientation, the keying protrusion aligns away from the keying flange and allows the drive to couple with the backplane circuit board.

Abstract: An example method for communicating radio frequency (RF) settings to a wireless networking device to adaptively configure the wireless networking device in events of weather changes is presented. A network device may receive a weather metric corresponding to a wireless networking device and identify a target RF setting for the wireless networking device corresponding to the weather metric. Further, the network device may transmit the target RF setting to the wireless networking device to cause the wireless networking device to operate with the target RF setting thereby enhancing the performance of the wireless networking device.

Abstract: A resource optimization processor is disclosed for inclusion in peer routers. The resource optimization processor performs a method for resource optimization of the routers. The method includes disabling an inter-switch link (ISL) between peer routers and monitoring downstream links between a primary router and downstream devices connected to the primary router. The method further includes identifying a failure of at least one downstream link and enabling the ISL between the first router and the second router for the failed downstream link upon identification of the failure.

Abstract: Data-driven intelligent networking systems and methods are provided. The system can accommodate dynamic traffic with fast, effective flow control of individual applications and traffic flows in conjunction with an end host. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow can be acknowledged after reaching the egress point of the network, and the acknowledgement packets can be sent back to the ingress point of the flow along the same data path. As a result, an ingress edge switch can perform fine grain flow control of individual sources of the flows residing on an end host.

Abstract: A crosstalk regulator for a cabinet includes a cable management component having a ring portion surrounding a central axis and a plurality of teeth protruding radially outward from the ring portion. The teeth define a plurality of slots distributed around a circumference of the ring portion. Each slot is defined between a pair of adjacent teeth and extends parallel to the central axis. Each tooth includes a first portion and a second portion, the first portion protrudes farther radially outward from the ring portion than the second portion. The cable management component is slidably disposed in the cabinet such that the second portion is disposed in the opening and the first portion is engaged to the cabinet to releasably retain the crosstalk regulator in the cabinet. Each slot routes one cable between controlled and external environments while maintaining a fixed distance between adjacent cables to regulate crosstalk among the cables.

Abstract: Systems and methods are provided for effectuating overlay tunnels between software-defined wide area network (SD-WAN) end-point devices despite the use of IPSec passthrough in one or more network devices, such as modems or routers that exist between the end-point devices. In particular, the Internet Key Exchange (IKE) protocol can be allowed to progress until a modem/router is able to establish an IKE tunnel, after which overlay packets using cloud-managed keys can be allowed to pass through the modem/router. An overlay tunnel may then be established between the end-point devices, and the IKE tunnel can be taken down.
