Permitted network risks in diverse route determinations

Systems and methods for permitted network risks in diverse route determinations introduce the concept of permitted network risks which are risks that may be present in a disjoint path calculation. This removes the binary logic in conventional shared risk path determination, i.e., either exclude or include. With the present disclosure, a network risk may be excluded (must never use) or shared (may use if needed). In an embodiment, if a route for a backup tunnel or path excluding all network risks is not possible, then a route for the backup tunnel or path may be found excluding some network risks of the primary tunnel or path except specified network risks that are determined/specified as permitted network risks. Such permitted network risks can be explicitly specified by a network operator or implicitly determined based on a category (e.g., node and/or equipment may be shared network risks whereas links may not).

Achieving highly available autonomous systems (AS) in a source-selected path routing network
11362932 · 2022-06-14 · ·

The present application refers to a method and a system for reliably forwarding data packets in a source-selected path routing network including a plurality of autonomous systems. For this purpose, a data plane of each of the plurality of autonomous systems that comprises one or more border routers and a control plane of each of the plurality of autonomous systems that comprises a control service are split into two or more shards. Each of said shards contains exactly one control service and at least one border router and is responsible for processing, storing and propagating path information only for a subset of existing links between an autonomous system and a neighboring autonomous system within the source-selected path routing network. Hence, in the source-selected path routing network, each individual shard is not critical and thus can fail without compromising the availability of the entire system.

Path selection for integrated access and backhaul

A method may include identifying paths from a user equipment (UE) device to an anchor station, determining that a first path corresponds to a direct wireless link to the anchor station and determining, in response to determining that the first path corresponds to a direct wireless link, a signal quality and a congestion associated with the direct wireless link. The method may also include selecting, in response to determining that the signal quality satisfies a signal quality threshold and the congestion satisfies a congestion threshold, the first path for the UE device to use when communicating with the anchor station. The method may further include identifying, in response to determining that the signal quality does not satisfy the signal quality threshold or the congestion does not satisfy the throughput threshold, another path for the UE device to use when communicating with the anchor station.

Traffic Availability in a Cellular Communication Network
20210360486 · 2021-11-18 ·

According to a first aspect, it is provided a method performed in a network node of a cellular communication network. The method comprises the steps of: obtaining an indicator to secure a traffic availability for a connection, wherein the traffic availability is related to how likely the connection will remain operable; determining whether the network node can secure resources to support the traffic availability; allocating resources for the connection when resources can support the traffic availability; and transmitting a positive response when the network node can secure resources to support the traffic availability. Corresponding network nodes, wireless nodes, computer programs and computer program products are also provided.
