Abstract: Techniques are described herein for network slice support of respective transport protocols. In one example, a session management function obtains, from a user equipment, a request for a network slice identifier in a network that includes a plurality of network slices each configured to support a respective transport protocol. In response to the request, the session management function identifies a first transport protocol of the respective transport protocols by which the user equipment is to communicate. Based on the first transport protocol, the session management function identifies a first network slice of the plurality of network slices by which the user equipment is to communicate. The first network slice is configured to support the first transport protocol. The session management function provides the network slice identifier to the user equipment. The network slice identifier corresponds to the first network slice.

Abstract: Wireless dynamic file exchange is provided by, in response to a triggering network condition occurring, initiating an exchange of a parameter file including non-layer two content via a 802.11 message, such as a Generic Advertisement Service (GAS) message between an access point (AP) and a station (STA) connected to the AP; and in response to determining that the exchange was unsuccessful, terminating a connection between the AP and the STA. The parameter file may be sent over several messages and update the parameters for a new session or an existing session. Devices that do not conform to the updated parameters may be disassociated from the AP and re-connect to receive and implement the updated parameters.

Abstract: Techniques are described herein for pairing disaggregated network elements. In one example, a pairing manager obtains an indication to prioritize high availability when pairing disaggregated network elements. The disaggregated network elements include first disaggregated network elements and second disaggregated network elements. The pairing manager obtains, from one or more of the disaggregated network elements, topology information of the disaggregated network elements. Based on the topology information and the indication to prioritize high availability, the pairing manager pairs topologically-adjacent ones of the first disaggregated network elements with different ones of the second disaggregated network elements.

Abstract: A method provides for receiving network traffic from a host having a host IP address and operating in a data center, and analyzing a malware tracker for IP addresses of hosts having been infected by a malware to yield an analysis. When the analysis indicates that the host IP address has been used to communicate with an external host infected by the malware to yield an indication, the method includes assigning a reputation score, based on the indication, to the host. The method can further include applying a conditional policy associated with using the host based on the reputation score. The reputation score can include a reduced reputation score from a previous reputation score for the host.

Abstract: Methods are presented herein for a reduced state machine that describes nodes and relationship dynamics representing real network elements (networking devices and software processes) in a computer/data network, and abstracted logical items. Logical states of networking features of the network elements are reflected in the graph, while configuration data is stored for completeness. A method called a “Versioner Algorithm” is provided to record the temporal history of a node and its state over time within the node's metadata itself, while recorded relationships represent logical relations between observed nodes. A method is also provided to time-travel back to observe a historical view of the network. Further still, a method is provided to a difference of two historical topologies and return that data in human-readable or machine consumable form.

Abstract: Systems, methods, and computer-readable storage media are provided for provisioning a common subnet across a number of subscribers and their respective virtual networks using dynamically generated network policies that provide isolation between the subscribers. The dynamic generation of the network policies is performed when a host (e.g. client) is detected (via a switch) as the host joins the computing network via virtual networks. This ability to configure a common subnet for all the subscriber virtual networks allows these subscribers to more easily access external shared services coming from a headquarter site while keeping the separation and segmentation of multiple subscriber virtual networks within a single subnet. This allows the Enterprise fabric to be more simple and convenient to deploy without making security compromises.

Abstract: Devices, systems, methods, and processes for orchestrating and managing various lower-power modes in a variety of network devices within a network are described herein. Various network devices, such as access points may be capable of entering one or more lower-power modes of operation that utilize less electricity to operate. When initiating a lower-power mode, the various clients that the network device has been handling need to be handed off to a sibling AP nearby. However, when exiting these lower-power modes, these devices may need different amounts of time to reboot and/or resume normal operations. Thus, when deciding which clients to re-associate with the waking up network device, various considerations need to be weighed based on client needs and network device capabilities. Thus, a smart environmental controller (SEC) is utilized to coordinate these processes. The SEC can be a specialized device, or a logic distributed remotely or among the network devices.

Abstract: Multiple listlets function as a single master linked list to manage data packets across one or more banks of memory in a first-in first-out (FIFO) order, while allowing multiple push and/or pop functions to be performed per cycle. Each listlet can be a linked list that tracks pointers and is stored in a different memory bank. The nodes can include a pointer to a data packet, a pointer to the next node in the listlet and a next listlet identifier that identifies the listlet that contains the next node in the master linked list. The head and tail of each listlet, as well as an identifier each to track the head and tail of the master linked list, can be maintained in cache. The individual listlets are updated accordingly to maintain order of the master linked list as pointers are pushed and popped from the master linked list.

Abstract: Described herein are devices and methods for calculating a network sustainability index (NSI) and providing specific remediation/action plans to achieve better sustainability in network infrastructures. The NSI is calculated based on one or more of three main parameters: a reporting parameter, an optimization parameter, and/or a device energy efficiency rating. The reporting parameter may evaluate the capability of each device to report its power consumption, considering factors such as granularity, component-level reporting, and reporting frequency. The optimization parameter may assess whether a device participates in network energy optimization. The device energy efficiency rating may evaluate the energy efficiency of each device. A recommendation portal offers actionable insights and remediation plans based on the calculated NSI. The devices and methods allow administrators to list eligible devices for energy optimization, ensuring a comprehensive approach to network sustainability and facilitating targeted measures for improved energy efficiency.
