Abstract:
The disclosure provides a service provisioning method to support configurations of admission control, and resource control policies for constrained devices by using commissioning procedure. the apparatus comprises the obtaining module configured to obtain at least one service information including at least one pre-registered service along with associated device ID from said commissioning device, the creation module configured to create at least one service ID against said service information received, and create said admission control policy and/or said resource control policy for said service ID, the lookup module configured to look up service ID associated with said service in said provisioning device, on receipt of at least one request, from said client device, to access said service, and the access module configured to grant/deny access for said service, based on said policies decided, to said client device.
Abstract:
In one implementation, the present invention provides a mechanism for balanced ad-hoc network formation. To achieve the for balanced ad-hoc network formation, the present invention sends the metric information with DIO control message. A new metric container type is introduced in RPL to hold the metric information, and select the parent with minimum path cost, and switch the parent with minimum path cost, as per the defined logic. A stateless metric considers that the average traffic flow from each node is approximately same. The stateless metric directly uses the number of routing table entries (RTsize) to decide which path to use. A stateful metric, wherein the node keeps a track of packets processed per second by itself. For stateful metric, the node maintains packets processed rate (PPR) variable, which is then used as the metric.
Abstract:
This application discloses a route information storage method. The method is applied to a wireless mesh network, the wireless mesh network includes a first node, a second node, and at least two stations STAs, the first node is an upper-level node of the second node, the at least two STAs include a first STA and a second STA, and the first STA and the second STA are connected to the second node. In the method, the first node receives a routing request for access requested by the first STA, and if it is determined that a first route entry corresponding to the second STA already exists, the first node no longer generates a new route entry for the first STA, but reuses the first route entry.
Abstract:
The embodiments of the present invention provide a bandwidth management device, central management device and method of bandwidth management. The bandwidth management device includes: a first receiver, configured to receive attribute information of media devices; wherein a criticality factor of media device is included in each piece of the attribute information; a second receiver, configured to receive media streaming from the media devices; a bandwidth assigner, configured to assign bandwidth for each piece of media streaming based on the criticality factor. Through the embodiments of the present invention, optimization of bandwidth usage is realized and it is easy to change the critical level of video streaming adaptively.
Abstract:
The present disclosure relates to apparatus and methods for route invalidation. In one example method, a common ancestor node of a network determines switching of a parent node of a node based on an update message received from the node using a new routing path established based on the switching of the parent node. The common ancestor node generates a No-Path message based on the update message. The No-Path message is for invalidating a previous routing path associated with the node on the switching of the parent node. The update message comprises at least one bit authorizing generation of the No-Path message by the common ancestor node. The at least one bit is placed in a transit information option in the update message.
Abstract:
Apparatus and method for optimized route invalidation using modified no-path DAO signaling are disclosed. According to the present invention, a node switching its current parent is adapted to send a regular Destination Oriented Directed Acyclic Graph (DODAG) Advertisement Object (DAO) message. Using the changed signaling, the common ancestor node generates an NPDAO on behalf of the switching node on receiving a refreshed DAO from an alternate path. The common ancestor node according to the present invention reuses a same PathSequence from the regular DAO based on which the NPDAO gets generated. The common ancestor node detects routing anomaly using next hop mismatch on reception of the DAO to generate the NPDAO on behalf of the target node. The No-Path DAO traverses downward/downstream along the previous path, unlike any other DAO messages traverses upstream according to convention approaches. The present invention provides a new signaling mechanism for route invalidation in constrained networks.
