A method is provided in one example embodiment and includes creating a segment organization, which includes a configuration profile. The method also includes attaching the configuration profile to a server in the segment organization. The method further includes sending the attached configuration profile to a database in a physical network.

Physical network orchestration for data centers

A source host device masks the hardware address of a hosted container from a network device to mitigate the use of resources in the network device. A virtual switch on the source host receives a frame from a hosted container. The frame includes a source hardware address of the hardware address corresponding to the hosted container. The frame also includes a source network address of the network address corresponding to the hosted container. The virtual switch replaces the source hardware address of the frame with the hardware address associated with the source host, and send the frame to the network device. The frame sent to the network device includes the host hardware address as the source hardware address and the container network address as the source network address.

Mitigating network/hardware address explosion in network devices

A network device is configured to establish a messaging bus with a container networking plug-in, which is associated with a container virtual network. The network device is also configured to obtain, via the messaging bus, networking information for one or more containers hosted at the at least one container-hosting computing device. Based on the networking information, the network device provides visibility of one or more containers below the network device.

Orchestrator agnostic application container visibility

Systems and methods are provided for a multicast based solution to solving the slow-start problem that ensures both optimal (1-hop) and in-sequence delivery of packets to the destination. Packets are hardware switched thereby completely eliminating the slow software switching path.

'Slow-start' problem in data center networks and a potential solution

In one embodiment a method includes receiving a first message including information regarding a first host connected to a first tunnel endpoint in a first network domain, the received information being encoded in accordance with a control plane protocol of the first network domain; translating the received first message in accordance with an API and/or a database schema of a second network domain; and transmitting the translated first message to the second network domain. The method further includes receiving a second message comprising information regarding a second host connected to a second tunnel endpoint in the second network domain, the received information being encoded in accordance with the API and/or the database schema of the second network domain; translating the second received message in accordance with the control plane protocol of the first network domain; and transmitting the translated second message to the first network domain.

Techniques for interconnection of controller- and protocol-based virtual networks

In some embodiments, a data packet may be received at a leaf switch. A port-channel associated with a destination port for the data packet may be identified, and the data packet may be transmitted to the destination port via the identified port-channel.

Two-stage port-channel resolution in a multistage fabric switch

A method is described and in one embodiment includes receiving at a top-of-rack ('TOR') switch a notification concerning a virtual machine ('VM'), wherein the received notification identifies a host associated with the VM; determining whether the identified host is directly connected to the TOR switch; and if the identified host is not directly connected to the TOR switch, identifying an intermediate switch to which the identified host is directly connected; and determining whether the identified intermediate switch to which the identified host is directly attached is attached to the TOR switch.

Techniques for integration of blade switches with programmable fabric

An example method for implementation of virtual extensible local area network (VXLAN) in top-of-rack (ToR) switches in a network environment is provided and includes receiving a packet encapsulated with a VXLAN header having an unknown virtual tunnel endpoint (VTEP) Internet Protocol (IP) address in a network environment, and installing an entry at an index location of a forwarding table. The index location includes an encoding of the VTEP-IP address as a VTEP index (VTEP-IDX), and the entry maps a VXLAN interface to an IP address associated with a VXLAN network identifier (VNI). In specific embodiments, the VTEP-IDX is log N bits, where N is a size of the forwarding table. The forwarding table indicates a destination VTEP IP address when encapsulating the packet, and the source VTEP IP address when decapsulating the packet.

Implementation of virtual extensible local area network (VXLAN) in top-of-rack switches in a network environment

A method is provided in one example embodiment and includes receiving at a first network element a packet from a second network element; processing the packet at the first network element to obtain information regarding an identity of a virtual machine ('VM') hosted by the second network element contained within the packet; and storing at the first network element the identifying information. The identifying information stored at the first network element is accessible by at least one third network element. In some embodiments, the first network element comprises a physical switch and the second network element comprises a virtual switch.
