A logical router includes disaggregated network elements that function as a single router and that are not coupled to a common backplane. The logical router includes spine elements and leaf elements implementing a network fabric with front panel ports being defined by leaf elements. Control plane elements program the spine units and leaf to function a logical router. The control plane may define operating system interfaces mapped to front panel ports of the leaf elements and referenced by tags associated with packets traversing the logical router. Redundancy and checkpoints may be implemented for a route database implemented by the control plane elements. The logical router may include a standalone fabric and may implement label tables that are used to label packets according to egress port and path through the fabric.

An apparatus includes a memory configured to store labels of virtual private networks (VPNs) in a first local label space. The apparatus also includes a processor to assign a first label block identifier (LBI) to a first block of labels in the first local label space and assign a first tuple to a first VPN. The first tuple includes the first LBI and a first label index (LI) that indicates a location of a first label of the first VPN within the first block of labels. The apparatus also includes a transceiver configured to provide the first tuple to routers that allocate second blocks of labels from second local label spaces based on the first tuple. The second routers store the first label at locations in the second label spaces indicated by the first LI.

An apparatus, system, method, and computer-readable recording media perform smart control in a wireless network, which includes a plurality of wireless devices. Configuration parameters are obtained to set one wireless device as an active master device in the wireless network. The active master device receives updates in the configuration parameters and learned station (STA) information, and periodically transmits the updates to the configuration parameters and the learned STA information to the other wireless devices in the wireless network. Any one of the other wireless devices in the wireless network can use the updates to the configuration parameters and the learned STA information to be set as a new active master device in the wireless network when the active master device becomes out of network.

In one embodiment, a New Radio (NR) core network system comprises a set of network functions to: receive a request from a user equipment (UE) device comprising a virtual local area network data network name (VLAN DNN); determine whether the UE device is authorized to access a particular VLAN implemented on the core network and associated with the VLAN DNN; and cause a message comprising a VLAN identifier (VLAN ID) to be transmitted to the UE device based on a determination that the UE device is authorized to access the particular VLAN, wherein the VLAN ID corresponds to the particular VLAN.

This application disclose a link configuration method, to configure a DSVPN tunnel interface parameter. A controller obtains a first link profile for a first site and a second link profile for a second site from a link profile library, where the link profile library includes a plurality of link profiles. The controller obtains preconfigured global configuration information, where the global configuration information includes an address pool. The controller generates a first link configuration parameter of the first site and a second link configuration parameter of the second site based on the address pool, the first link profile, and the second link profile and according to a preset link configuration rule. The controller sends the first link configuration parameter to the first site and sends the second link configuration parameter to the second site.

In one embodiment, a method according to the present disclosure includes receiving a topology change advertisement at a remote core edge node and performing a network address information removal operation. The topology change advertisement is received from a core edge node that is in communication with an access network. The topology change advertisement indicates that a topology change has occurred in the access network. The network address information removal operation removes network address information stored by the remote core edge node. The network address information is used by the remote core edge node in participating in communications with the core edge node.

The present disclosure relates to a 5th (5G) generation or pre-5G communication system for supporting a higher data transmission rate beyond a 4th (4G) generation communication system such as long term evolution (LTE). According to embodiments of the present disclosure, a method performed by a packet classifier for a virtual enterprise network (VEN), in a wireless communication system, may include receiving an Ethernet packet from a user plane function (UPF), obtaining a source medium access control (MAC) address and virtual local area network (VLAN) identification information of the Ethernet packet, identifying a virtual switch (VSW) of an enterprise corresponding to the source MAC address and the VLAN identification information, forwarding the Ethernet packet to the VSW, and authenticating a member of a virtual network group based on a MAC address.

In some embodiments, a non-transitory processor-readable medium stores code representing instructions configured to cause a processor to receive, from an access switch, a first signal including forwarding state information associated with a first peripheral processing device from a set of peripheral processing devices. The code can further represent instructions configured to cause the processor to receive, from the first peripheral processing device, a second signal including a data packet. The code can further represent instructions configured to cause the processor to send, to a replication engine associated with the set of peripheral processing devices, a third signal such that the replication engine (1) defines a copy of the data packet, which is included within the third signal, and (2) sends, to a second peripheral processing device from the set of peripheral processing devices, a fourth signal including the copy of the data packet.

Provided in embodiments of the present disclosure are a method and a device for bearing a multicast virtual private network. The method includes: assigning, by a BFIR accessing a VRF, a global VPN identifier to a multicast VRF, and carrying the global VPN identifier to notify a route to a BFER accessing the multicast VRF; after receiving a packet of the multicast VRF, encapsulating, by the BFIR, the packet with a BIER header and forwarding the packet, the forwarded packet carrying the global VPN identifier.
