Systems, methods, and devices for offloading network data to a datastore. A system includes a plurality of instances of a datastore node in a single networking device, each of the plurality of instances of the datastore node comprising: a datastore; a publisher independent of the datastore for publishing data to the datastore; a subscriber independent of the datastore for receiving information from the datastore; a replicator agent configured to connect to the datastore as a publisher or a subscriber; and a persistent storage agent configured to connect to the datastore as a publisher or a subscriber.

Single node and multiple node datastore architecture in a network routing environment

Systems, methods, and devices for improved routing operations in a network computing environment. A system includes a first switch and a second switch in a network topology. The system includes a host virtual machine in communication with at least one of the first switch and the second switch. The system includes a routed peer link connecting the first switch to the second switch. The system is such that the first switch and the second switch have the same Internet protocol (IP) address and media access control (MAC) address.

First hop gateway redundancy in a network computing environment

Systems, methods, and devices for offloading network data to a datastore. A system includes a publisher device in a network computing environment. The system includes a subscriber device in the network computing environment. The system includes a datastore independent of the publisher device and the subscriber device, the datastore comprising one or more processors in a processing platform configurable to execute instructions stored in non-transitory computer readable storage media. The instructions includes receiving data from the publisher device. The instructions include storing the data across one or more of a plurality of shared storage devices. The instructions include providing the data to the subscriber device.

Independent datastore in a network routing environment

In one embodiment, the system may identify a virtual network, the virtual network including a plurality of virtual entities and connections among the plurality of virtual entities. The system may automatically map each of the plurality of virtual entities to one or more resources or resource pools such that the virtual network is mapped to a physical network, wherein mapping includes allocating one or more resources or resource pools to a corresponding one of the plurality of virtual entities.

Physical resource life-cycle in a template based orchestration of end-to-end service provisioning

An example method is provided and may include multicasting a discovery packet in an overlay network, which includes a Layer 2 scheme over a Layer 3 network; and identifying endpoints based on their respective responses to the discovery packet, where the endpoints are coupled across a multicast backbone. In more specific embodiments, the method may include identifying disconnected endpoints in the overlay network based on a lack of responses from the disconnected endpoints.

System and method for discovering multipoint endpoints in a network environment

In one embodiment a method and apparatus that support virtual services including virtual network interface control functionality for virtual machines running on a server. A method includes receiving a packet at a network interface card from a data communication network, classifying, within the network interface card, the packet to select one of multiple flow tables to which the packet should be assigned to obtain a selected flow table, the classifying being based, at least, on a logical interface with which the packet is associated, processing the packet based on information stored in the selected flow table, and passing the packet to a virtual machine operating on a computer to which the network interface card is communicatively connected, the virtual machine being associated with the logical interface.

Network interface controller for virtual and distributed services

In one embodiment, a method includes receiving a request packet at a flow director in communication with a plurality of servers, each server comprising a virtual load balancer module and one or more virtual machines and forwarding the request packet to one of the virtual load balancer modules at one of the servers. The virtual load balancer module is configured to select one of the virtual machines to receive the request packet and transmit a response packet. The response packet is transmitted without passing through the flow director. An apparatus for load balancing in a virtual machine environment is also disclosed.

Distributed load balancer in a virtual machine environment

In one embodiment, the system may identify a virtual network, the virtual network including a plurality of virtual entities and connections among the plurality of virtual entities, wherein each of the plurality of virtual entities is mapped to one or more of a plurality of resources such that the virtual network is mapped to a physical network. The system may automatically obtain data during operation of the physical network, and provide a representation of the virtual network and the data obtained during operation of the physical network.

Physical resource to virtual service network mapping in a template based end-to-end service provisioning

Increased usage of network links is provided and smaller forwarding tables are required. A combination of STP and Multipath methods may be implemented in a network. Frames may be forwarded between switches not only according to MAC addresses, but also according to switch IDs and local IDs. Switch IDs do not need to be globally unique, but should be unique within a particular network. Local IDs need only be unique within a particular switch. Some preferred implementations allow frames to be delivered in order to devices requiring in-order delivery. Preferably, core switches need only learn the switch IDs of each core switch and each edge switch, and the appropriate exit port(s) corresponding to each switch. Preferably, the forwarding tables of each edge switch indicate the addresses of each device attached to that edge switch, the address of each device that is in communication with an attached device and the address of every other switch in the network.

Forwarding table reduction and multipath network forwarding

A solution is provided wherein the interfaces between multiple chassis (e.g., edge switches) in a network of layer 2 devices and a spanning tree device are treated as a single emulated switch. This emulated switch effectively enables two different views to the two different sides. Thus, frames from the network of layer 2 switches destined to any port of the emulated switch may take any of the links (through any of the physical switches), thereby enabling effective load-balancing for frames traveling from the layer 2 network side into the spanning tree device. Meanwhile the spanning tree device does not recognize an illegal loop in its connection to two different edge switches as it views the two links as a single logical EtherChannel.

Multi-chassis emulated switch

In one embodiment, an apparatus obtains a switch port identifier mapping for each of the plurality of ports of a network device, wherein the switch port identifier mapping indicates a port identifier of one of the plurality of ports of the network device and a switch port identifier of a switch port to which the one of the plurality of ports is connected. The apparatus obtains a set of switch information for each of a plurality of switches, the set of switch information including a set of switch port identifiers associated with the corresponding one of the plurality of switches. The apparatus ascertains for each one of the plurality of ports, a corresponding one of the plurality of switches and a port of the one of the plurality of switches to which the one of the plurality of ports is connected.
