27 Jun 2014TL;DR: In this article, a hardware shadow is used to copy data from a shadow table to a corresponding table in the hardware forwarding engine, where the shadow is a copy of the data stored in hardware tables for the forwarding engine.
Abstract: A method and apparatus of a device that uses a hardware shadow for a central processing unit failover is described. In an exemplary embodiment, a device receives a signal that the active central processing unit has failed, where the active central processing unit controls the processing functions of the network element and the network element includes a hardware forwarding engine and a hardware shadow. The hardware shadow additionally includes multiple shadow tables. For each shadow table, the device copies data from that shadow table to a corresponding table in the hardware forwarding engine, where the hardware shadow is a copy of the data stored in hardware tables for the hardware forwarding engine. In response to the copying, the device further switches control of the network element processing functions from the active central processing unit to a standby central processing unit.

18 Mar 2015TL;DR: In this paper, a system, method, and associated apparatus for continuous measurement of transit latency in individual data switches and multi-device topologies is disclosed, which enables an accurate measure of real-word latency on production networks by applying a time stamp to production network data on ingress to a network element and determining a traversal time by capturing the time stamp on egress from the network element.
Abstract: A system, method, and associated apparatus for continuous measurement of transit latency in individual data switches and multi-device topologies is disclosed, which enables an accurate measure of real-word latency on production networks by applying a time stamp to production network data on ingress to a network element and determining a traversal time by capturing the time stamp on egress from the network element. In one embodiment, time stamps applied to network data are removed on egress to avoid undesirable packet growth across multiple hops of the network. Timing information on data flow through the data/forwarding plane of each network node of a production network can be gathered without the use of test harnesses, injected network data, or dedicated ports.

09 Jan 2015TL;DR: In this paper, a method and system for maintaining persistent network policies for a virtual machine (VM) that includes determining a name of the VM executing on a first host connected to a first network device is presented.
Abstract: A method and system for maintaining persistent network policies for a virtual machine (VM) that includes determining a name of the VM executing on a first host connected to a first network device; binding the name of the VM to a network policy for the VM on the first network device; acquiring from VM management software, using the name of the VM, a universally unique identifier (UUID) of the VM; associating the UUID to the network policy on the first network device; applying the network policy for the VM on the first network device; subscribing to receive notifications from the VM management software of changes to the configuration of the VM corresponding to the UUID; receiving notification from the VM management software of a configuration change made to the VM corresponding to the UUID; and updating the network policy of the VM to reflect the configuration change of the VM.

01 Jul 2014TL;DR: In this paper, the authors describe using overlay routing mechanisms in an Internet Protocol (IP) fabric to enable communication between servers in different layer 2 domains to communication, including direct routing, indirect routing, naked routing, or a combination thereof.
Abstract: In general, embodiments of the invention relate to routing packets between servers in different layer 2 domains. More specifically, embodiments of the invention relate to using overlay routing mechanisms in an Internet Protocol (IP) fabric to enable communication between servers in different layer 2 domains to communication. The overlay routing mechanisms may include direct routing, indirect routing, naked routing, or a combination thereof (e.g., hybrid routing).

19 Mar 2017TL;DR: The key metrics of analog coherent interfaces for today's 200G 16QAM and future 400–600G 64QAM pluggable systems and a cloud service provider perspective on next generation DCI requirements are discussed.
Abstract: We discuss the key metrics of analog coherent interfaces for today's 200G 16QAM and future 400–600G 64QAM pluggable systems. A cloud service provider perspective on next generation DCI requirements is also discussed.
