摘要:
The present invention discloses a method for selecting a real-time service data transmission path, comprising establishing an independent bearer control layer comprising more than one bearer network resource manager between a service control layer and a bearer network. The method further comprises: after a source bearer network resource manager which is connected to the service control layer receives a connection request for a real-time service, orderly selecting and determining, from the source bearer network resource manager towards a destination bearer network resource manager, an intra-domain route path for the real-time service in a management domain corresponding to each bearer network resource manager, and an inter-domain route path between adjacent management domains corresponding to adjacent bearer network resource managers. In addition, the present invention discloses six methods for selecting a real-time service data transmission path based on different strategies. The methods according to the present invention can increase success ratio of routing, and can obtain an optimal route in simple and flexible manners, thus can guarantee reasonable allocation of resources.

The present invention discloses a method for implementing cross-domain resource management. If requesting for service connection resources, for each domain, a border Call Agent (CA) first sends a connection resource request to a specific bearer network resource manager in its domain. This bearer network resource manager decides whether the destination user's device is in its administration domain. If yes, it makes an appropriate processing and returns a response of a successful processing to the CA it belongs to; if not, the bearer network resource manager performs an appropriate preprocessing and sends back a response of a successful preprocessing to the CA it belongs to, and after receiving the response, the CA sends a connection resource request to its next-hop CA.

The invention discloses a method for implementing resource applications of multiple service flows, including: receiving by a connection manager (CM) a connection resource request message including resource applications of at least two service flows; allocating paths and reserving resources for the service flows by the CM; sending by the CM the paths allocated for the service flows and resources reserved for the service flows to an edge router of a bearer network accessed by the service flows. With the method, resource applications of multiple service flows may be accomplished in one service connection, thereby providing support for rich QoS services of the application layer, reducing the time of signaling exchange between devices, saving the network traffic and the time of resource applications
摘要:
A method for processing device overload in a communication network includes: a device involved in a service connection checking in real time whether processing capability of the device exceeds an overload threshold set in the device, and sending to a neighboring device of the device an overload alarm message containing an address of the device if the processing capability of the device exceeds the overload threshold; the neighboring device restricting traffic passing through the device after receiving the overload alarm message. The method of the present invention enables the device involved in the service connection to automatically lead the establishment of the subsequent service connection reasonably, which improves the operation efficiency of network and shortens the processing delay of service connection.
摘要:
A method for allocating bearer network resources is disclosed, which includes: each bearer network resource manager deciding after receiving a QoS resource request whether the destination user of the QoS resource request is an intra-domain user, if yes, selecting an intra-domain LSP, allocating resources on the selected intra-domain LSP, and terminating the procedure; otherwise selecting an inter-domain LSP based on the inter-domain routing policy pre-configured in the bearer network resource manager, and allocating resources on the selected inter-domain LSP; then selecting an intra-domain LSP based on the information of the selected inter-domain LSP and the service information, and allocating resources on the selected intra-domain LSP; and sending the QoS resource request with the information of the selected inter-domain LSP carried in to the downstream bearer network resource manager. This invention makes it possible for the operator to allocate resources according to a routing policy.

The embodiments of this invention disclose a method and system for forwarding traffic in a bearer network. The method includes: a CA related to a service call instructing a bearer network resource manager managed by the CA to allocate a QoS policy and reserve resources for the service call; the bearer network resource manager issuing the QoS policy to an edge device in a management domain managed by the bearer network resource manager; the edge device forwarding traffic matching the QoS policy after bearer network resource managers managed by CAs related to the service call successfully allocate QoS policies and reserve resources. With the embodiments of this invention, the bearer network may be controlled precisely whether to forward traffic, and thus it may be avoided effectively that traffic is imported into the bearer network before the service connection is established so as to acquire exact service data amount.

摘要:
A portable computing device including a housing having a top surface and a bottom surface connected to one another by a pair of sides, a proximal end and a distal end, the top surface including a user interface for operation by a user. The device comprises a planar surface located on the bottom surface at the proximal end, such that the planar surface extends to either side of a centerline of the housing and in a direction towards the distal end. The planar surface defines a plane and the centerline extends in a direction between the proximal end and the distal end. The device has at least one protrusion located on the bottom surface at the distal end, such that the at least one protrusion extends between the bottom surface and the plane, such that the at least one protrusion has a respective peripheral surface lying on the plane on both sides of the centerline. The at least one protrusion and the planar surface provide stability of the device when placed on a surface adjacent to the bottom surface, the stability facilitating operation of the user interface by the user.
