摘要: Aspects of the present disclosure involve systems for providing multiple egress routes from a telecommunications network for a client of the network. In general, the system provides for a client of the network to receive intended packets of information through multiple connections to the network such that load balancing and failover services for traffic to the customer are provided. The process and system allows for telecommunications network to utilize a common next-hop value of announced border gateway protocol (BGP) routes to advertise multiple routes to reach a destination customer network or address. By utilizing a common next-hop value in the announced BGP information, the devices of the network may load balance communication packets to the destination customer or address among the multiple egress locations from the network, as well as providing fast failover to alternate routes when a failure at the network or customer occurs.

摘要: A network device including an Ethernet transmission interface and a processing unit is provided. The Ethernet transmission interface is provided with at least one Ethernet transmission port. The processing unit is coupled to the Ethernet transmission interface and is configured to: in order to detect whether a packet looping exists, send out a dynamic host configuration protocol (DHCP) discover message through a linked Ethernet transmission port in response to linking one of the at least one Ethernet transmission port to a network and determine whether a DHCP offer message is received; determine whether to prohibit data transmission of the linked Ethernet transmission port according to whether the DHCP discover message returned through the packet looping is detected; classify the linked Ethernet transmission port as an uplink transmission port or a downlink transmission port according to whether the DHCP offer message is received.

摘要: Example implementations relate to a networking device. For example, an implementation may receive a data processing packet identified as belonging to a processing virtual local area network. The networking device may execute an instruction associated with the data processing packet on data associated with the data processing packet and store resultant data in the payload of the data processing packet. The networking device may route the data processing packet with resultant data stored in the payload to a next device.

摘要: The communication device of the embodiments is a communication device which, in a communication system having a management apparatus for acquiring device information on a device to be managed, transmits the device information to the management apparatus. The communication device includes a device information classifier and a unique information transmitter. The device information classifier classifies the device information into common information which is device information essential to the device related to the communication device and unique information which is device information unique to the device related to the communication device. The unique information transmitter transmits the unique information classified by the device information classifier to the management apparatus when there is a request from the management apparatus.

摘要: One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a network extension module, which maintains a mapping between a first virtual local area network (VLAN) identifier and a first global VLAN identifier of a network extension group. The network extension group is represented by a range of global VLAN identifiers for a tenant. A global VLAN identifier is persistent in a respective switch of the network and represents a virtual forwarding domain in the network. During operation, the network extension module includes the global VLAN identifier in a packet belonging to the first VLAN.

摘要: In a method for forwarding a packet, a physical forwarding unit receives a data packet, may find a first subnet route based on a destination IP address of the data packet, and forwards the data packet to a virtual forwarding unit via an output interface of the first subnet route. The virtual forwarding unit receives the data packet may find a first host route based on the destination IP address of the data packet, and forwards the data packet based on the first host route.
