A network device receives an attribute identifying paths associated with an open shortest path first (OSPF) domain of a network and an intermediate system to intermediate system (ISIS) domain of the network, and provides the attribute to other network devices of the network. The network device receives traffic destined for one of the other network devices of the network, and determines that a primary path is unavailable for routing the traffic to the one of the other network devices. The network device selects a secondary path from the paths identified by the attribute. The secondary path is selected based on determining that the primary path is unavailable, and the secondary path is associated with the OSPF domain or the ISIS domain of the network. The network device provides the traffic to the one of the other network devices via the secondary path.

At a router, at least one memory and computer program code stored therein are configured to, with at least one processor, cause the router to: determine source router identification information for a tunnel traversing the router based on a routable source IP address for the tunnel; determine destination router identification information for the tunnel based on a routable destination IP address for the tunnel; program a bit string entry for the tunnel in a Bit Index Forwarding Table (BIFT) for tunnels from a source router to a plurality of destination routers, the BIFT being indexed based on the source router identification information and at least a portion of the destination router identification information; and route packet data received at the router according to the BIFT.

A reservation request is received for a data transport session. The reservation request contains a requested class of communication service through the asynchronous network. The state of the network along the route is then preferably determined and at least one end-to-end route through the network is obtained. The route is based on the requested class of communication service and the state of the network. The data transport session is then controlled, such that data is forced to travel along at least one route through the asynchronous network. This is preferably done by controlling multiple data controllers dispersed along the at least one route by mapping specific data protocols to specific routes, or mapping specific data protocols to specific ports in each data controller. If a state of the asynchronous network indicates that the route cannot transport data in conformity to the class of communication service, then the route is changed to a backup route through the network.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a bandwidth part switch from a first bandwidth part to a second bandwidth part. The user equipment may transition from the first bandwidth part to the second bandwidth part after determining the bandwidth part switch and based at least in part on a critical section defined for the transitioning from the first bandwidth part to the second bandwidth part. Numerous other aspects are provided.

The present invention relates to a network resource isolation method for container networks and a system implementing the method.

In one embodiment, an apparatus includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the apparatus to perform operations including determining a path through a plurality of provider nodes within a provider network and determining that the path through the plurality of provider nodes within the provider network is secure. The operations also include receiving, from a customer node, a Resource Reservation Protocol (RSVP) path message comprising an attribute for a security request. The operations further include routing the RSVP path message along the path of the plurality of provider nodes.

The present invention discloses communication methods, apparatuses and a system for sharing network resources in a communications network. It enables a path computation element (PCE) to notify path computation clients (PCCs) about the shared resources of independent label switch paths by allowing a PCE to send an association object with a new association type to PCC. A Path Computation Element (PCE) Communication Protocol extension that associates LSP's whose ingress, or egress, or both ingress and egress are different for resource sharing to avoid path computation failures or duplicate allocation of resources during common links for new LSP's created during an update of E2E LSP. The PCC employs Resource ReSerVation Protocol (RSVP) for LSP signalling, PCC forwards path message information along with association object to the RSVP for LSP signalling. The RSVP uses the association object in its reservation message for LSP setup.

[Object] To provide a communication control device configured to efficiently secure bands of an IP network in order to transmit data streams. [Solution] There is provided a communication control device including: a channel information acquisition unit configured to acquire, when AV streams are transmitted from a plurality of transmission apparatuses to one or more reception apparatuses on an IP network while being switched, all channel information from the transmission apparatuses to the reception apparatuses; a traffic calculation unit configured to calculate a maximum traffic generated in switching patterns of the transmission of the AV streams from the transmission apparatuses to the reception apparatuses, on the basis of the channel information acquired by the channel information acquisition unit; and a transmission band reservation unit configured to reserve a transmission band on the IP network, on the basis of the maximum traffic calculated by the traffic calculation unit.

Disclosed are a multi-layer LSP control method and apparatus. The method comprises: acquiring a label switched path (LSP) addition request, wherein the LSP addition request carries identifier information for identifying a layer associated group that the LSP is to be added to; and in response to the LSP addition request, adding the LSP to the layer associated group, wherein the layer associated group comprises: an upper-layer LSP and several lower-layer LSPs.

A network arbiter and associated method for linking and controlling the rate of data transmission between a sender on a connected network and a client with an advertised receive window are disclosed. The network arbiter comprises a downstream temporary storage for temporarily storing data in transmission from the sender to the client, an upstream temporary storage for temporarily storing data in transmission from the client to the sender and a processor operatively connected to the downstream temporary storage and the upstream temporary storage. The processor is configured to alter the advertised receive window in order to modulate the rate of data transmission.
