An apparatus includes a program instructing hardware and a computer readable storage medium coupled to the hardware and storing programming instructions for execution by the hardware. The programming instructions instruct the hardware to: receive a network device selection message sent by a first network device, where the network device selection message contains a virtual local area network (VLAN) mapping capability identifier of the first network device and a device identifier of the first network device; when determining that both the apparatus and the first network device have VLAN mapping capability according to local VLAN mapping capability and the VLAN mapping capability identifier of the first network device, select a network device for executing VLAN mapping according to sizes or a sequence of a local device identifier and the device identifier of the first network device.

In a VXLAN configuration method, a first network device obtains configuration information, generates first GRASP information based on the configuration information, and sends the first GRASP information to a second network device, where the configuration information includes VTEP device information, a plurality of pieces of VTEP device information are respectively used to indicate a plurality of VTEPs included in a VXLAN, the first GRASP information includes objective information, and the objective information is used to carry the configuration information. The second network device receives the first GRASP information and establishes a VXLAN tunnel based on the first GRASP information. In this way, automatic VXLAN configuration is implemented.

Described herein are systems and methods that provide for auto-discovery of VXLAN tunnel endpoints (VTEPs) using a protocol-independent multicast (PIM) bootstrap router (BSR). In one or more embodiments, a node may be configured via PIM messaging in which nodes of a network provide their candidate-rendezvous point (RP) advertisements send their information of candidate-RP to multicast group information to an elected BSR. The elected BSR consolidates the candidate-RP to multicast group information and propagates this information to nodes through PIM messages to all PIM routers in the network. In one or more embodiments, a node uses this information in combination with its local configuration mapping of VNIDs-to-multicast-group information to generate a remote VTEP-IP-(RP)-to-VNID mapping, which can be used to auto configure the node's VXLAN with remote-VTEP and VNI profiles in static VXLAN deployments.

Aspects of the disclosure involve systems and methods for utilizing Virtual Local Area Network separation in a connection, which may be a single connection, between a customer to a telecommunications network and a cloud environment to allow the customer to access multiple instances within the cloud through the connection. A customer may purchase multiple cloud resource instances from a public cloud environment and, utilizing the telecommunications network, connect to the multiple instances through a communication port or connection to the cloud environment. To utilize the single connection or port, communication packets intended for the cloud environment may be tagged with a VLAN tag that indicates to which cloud instance the packet is intended. The telecommunications network may route the packet to the intended cloud environment and configure one or more aspects of the cloud environment to analyze the attached VLAN tag to transmit the packet to the intended instance.

Systems, methods, and computer-readable media for managing nodes through virtual rack management modules. A system can have a first rack that includes a first top-of-rack (ToR) switch and a first group of nodes. The first ToR switch can be connected to the first group of nodes. The system can also have a second rack that includes a second ToR switch and a second group of nodes. The second ToR switch can be connected to the second group of nodes, and the second ToR switch can be connected to the first ToR switch. Furthermore, the system can include a rack management node that executes a hypervisor. The hypervisor can run a first virtual rack management module (vRMM) and a second vRMM. The first vRMM and the second vRMM can manage the first group of nodes and the second group of nodes, respectively.

Methods and systems for facilitating communication between two or more autonomous system instances include the instantiation of a bridge between the autonomous system (AS) instances. The bridge includes multiple virtual routers each of which is connected using a Layer 2 and a Layer 3 connection to a respective one of the AS instances. For example, each router may be connected to a respective AS instance by each of a virtual local area network (VLAN) connection and a Border Gateway Protocol (BGP) session. To facilitate the BGP session, the bridge may be assigned an AS number (ASN) different than that of each of the AS instances and that is exchanged between the routers and the AS instances. Routing within the bridge may be facilitated by the exchange of interior gateway protocol (IGP) information between the virtual routers.

Systems and methods are provided for redistributing virtual private network tunnels among a plurality of virtual private network concentrators. The method includes receiving, from each of the virtual private network concentrators, a respective utilization indicator; selecting a source one of the virtual private network concentrators according to the utilization indicators; selecting a destination one of the virtual private network concentrators according to the utilization indicators; selecting one of the virtual private network tunnels connected to the source one of the virtual private network concentrators; and transferring the selected one of the virtual private network tunnels from the source one of the virtual private network concentrators to the destination one of the virtual private network concentrators.

Systems and methods for managing network traffic receives, at a grade of service device, network traffic information for a plurality of network traffic channels from a network device separate from the grade of service device. The network traffic information is compared to a threshold to determine a behavior value for each network traffic channel. Each network traffic channel is mapped to a grade of service according to the behavior value.

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.
