Hard zoning of virtual local area networks in a fibre channel fabric

A network where FC and Ethernet storage traffic share the underlying network. The network extends FC SAN storage specific attributes to Ethernet storage devices. The network is preferably formed of FC switches, so each edge switch acts as an FCoE FCF, with internal communications done using FC. IP packets are encapsulated in FC packets for transport. Preferably, either each outward facing switch port can be configured as an Ethernet or FC port, so devices can be connected as desired. FCoE devices connected to the network are in particular virtual LANs (VLANs). The name server database is extended to include VLAN information for the device and the zoning database has automatic FCOE_VLAN zones added to provide a mechanism for enhanced soft and hard zoning. Zoning is performed with the conventional zoning restrictions enhanced by including the factor that any FCoE devices must be in the same VLAN.

A fabric for container virtual machines (CM) has cross fabric spine switches coupled to spine switches, each spine switch coupled to has a leaf switches, each leaf switch coupled to servers hosting CVM processes. Each of the leaf switches has an uplink port coupled to a spine switch leaf port configured in a mesh. The spine switches have a plurality of uplink ports for coupling to a plurality of cross fabric spine (CFS) ports into a mesh. The cross fabric spine switches keep a CF-NHCIB table of entries containing capabilities, and also a CF-FIB slice table which maintains entries for assignment of CVMs to new spine switches, such as GTID range, MAC Range, IP range associated with a spine port and spine address (MAC and/or IP) for transferring packets through the fabric.

A method is provided in one example embodiment and includes configuring on a network element a first tunnel from the network element to a first network, wherein the configuring comprises mapping a nexthop address of the local network element to a transport address of the tunnel on the network to create a first nexthop-to-transport mapping for the network element; and advertising the first nexthop-to-transport mapping along with routing information for the network element to remote network elements.

Secure SD-WAN port information distribution
11711242 · 2023-07-25 · ·

A Software Defined Wide Area Network (SD-WAN) edge node is disclosed. The SD-WAN edge node includes edge node SD-WAN ports coupled to untrusted underlay networks. The SD-WAN edge node transmits a first Border Gateway Protocol (BGP) update message advertising WAN (Wide Area Network) properties of the edge node SD-WAN ports to a local controller via an encrypted channel over the untrusted underlay network. The SD-WAN edge node receives a second BGP update message from the local controller, the second BGP update message advertising WAN properties of peer node SD-WAN ports of a peer node. The SD-WAN edge node establishes a security association with the peer node over the untrusted underlay networks based on the WAN properties of the edge node SD-WAN ports and the WAN properties of the peer node SD-WAN ports.

Service status notification

A provider edge (PE) device may receive traffic associated with one or more services, wherein the traffic includes a plurality of packets, and may determine, based on the plurality of packets, one or more packets respectively associated with each service of the one or more services. The PE device may determine, based on the one or more packets respectively associated with each service of the one or more services, a respective status of each of the one or more services. The PE device may generate type-length-value (TLV) data that indicates the respective status of each of the one or more services and may cause the TLV data to be added to a link layer discovery protocol (LLDP) packet. The PE device may send the LLDP packet that includes the added TLV data to a customer edge (CE) device.

Grade of service control closed loop

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.

Network monitoring apparatus and method thereof in programmable network virtualization

Disclosed is a computing apparatus implemented with a network hypervisor implementing software defined network (SDN)-based network virtualization. The computing apparatus include a statistics virtualization module configured to provide individual statistics to each of created virtual networks, a transmission disaggregation module configured to include a physical statistics cache that performs periodic monitoring of a plurality of physical switches and store statistics of the physical switches collected, and a physical statistics aggregation module configured to respond with statistics of the plurality of physical switches when a single monitoring request.

Smart control apparatus, system, method, and computer-readable recording media for a wireless network

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.

Packet forwarding method and network device
11706140 · 2023-07-18 · ·

A packet forwarding method and a network device are provided, and the method is applied to the network device. The network device includes a first virtual routing and forwarding (VRF) table and a second VRF table. The method includes: the network device receives a first packet. If the first packet carries tunnel attribute information, the network device forwards the first packet based on the first VRF table. The first VRF table includes one or more local routes, and next-hop outbound interfaces of the one or more local routes are all local outbound interfaces. The network device forwards the first packet based on the first VRF table, so that a packet from a tunnel may be forwarded to a local virtual machine for processing and may not be forwarded to another tunnel endpoint device, to avoid a routing loop during packet forwarding.
