摘要： Techniques for hot swapping and hot scaling containers between cloud services are disclosed. In one example, a method includes storing, with a cloud exchange, data indicating an association of a first container of a first private network with a second container of a second private network, wherein the first private network and the second private network are coupled to the cloud exchange to send and receive data packets via the cloud exchange. The method further includes sending, with the cloud exchange based on the association, state of the first container to the second container.

摘要： A method for identifying VLANs associated with a network includes gathering actual network element configuration data from a plurality of network elements in the network, wherein the actual network element configuration data identifies one or more VLANs that at least some of the plurality of network elements are actually allocated to; correlating the actual network element configuration data with administrative VLAN data; and determining one or more VLANs that are not commonly identified in both the actual network element configuration data and the administrative VLAN data. A system includes a network monitoring system operable to gather actual network element configuration data from a plurality of network elements at one or more logical network sites, wherein the actual network element configuration data identifies one or more VLANs that at least some of the plurality of network elements are actually allocated to; and a VLAN services module operable to correlate the actual network element configuration data with administrative VLAN data, and further operable to determine one or more VLANs that are not commonly identified in both the actual network element configuration data and the administrative VLAN data.

摘要： In some embodiments, an apparatus includes a management module configured to assign a unique set of identifiers to each network control entity from a set of network control entities. As a result, a network control entity from the set of network control entities can assign an identifier from its unique set of identifiers to a port in response to that network control entity receiving a login request from the port. The set of network control entities is associated with a distributed multi-stage switch. The management module is also configured to store a zone set database associated with the distributed multi-stage switch. The management module is configured to send an instance of an active zone set stored within the zone set database to each network control entity from the set of network control entities such that each network control entity can enforce the active zone set.

摘要： Embodiments of the present disclosure may include methods, systems, and computer readable media with executable instructions. An example method for network virtualization can include providing, by a datacenter (100) having physical and/or virtual resources, a number of virtual tenant datacenters (tDatacenters), each tDatacenter being isolated from other tDatacenters. A tenant virtual local area network (T-VLAN) (226, 228, 682) is associated to each of the number of tDatacenters, and a value of an end-to-end invariant network virtual local area network (VLAN) identification (VID) label (T-VID) is associated to a particular T-VLAN (226, 228, 682). A network packet associated with the particular T-VLAN (226, 228, 682) is modified at an edge network boundary (561) to include the T-VID. The T-VID is configured to have more than 4096 possible values.

摘要： The present invention discloses a service configuration method, apparatus and system. The provided method includes steps as follows: configuring a VLAN ID of a port on an intermediate device according to preset configuration information, where the port is connected to a client; after a DHCP request message which is from the client through the intermediate device is received, obtaining a MAC address in the DHCP request message, and obtaining an IP address corresponding to the MAC address from the configuration information; and sending a response message carrying the IP address and the VLAN ID to the client through the intermediate device, so that the client sets a local virtual local area network identifier to the VLAN ID and sets a local IP address to the IP address after receiving the response message.
