Peer state synchronization mechanism for dynamic network address translation (DNAT) in a network element
In general, embodiments of the invention relate to a method and system for enabling a peer state synchronization mechanism for dynamic network address translation (DNAT). More specifically, at least two network elements may be permitted to mount each other's DNAT tables, thereby providing redundancy for the implementation of DNATs in case of the failover of one of the network elements. The failed network element may then re-initialize while the functional network element continues to process packets, including packets that have been redirected to the functional network element post-failure of the failed network element. Upon completing re-initialization, the once failed network element recovers its DNAT table from the functional network element and proceeds to process packets normally. |

Bypassing a load balancer in a return path of network traffic
Some embodiments provide a method that allows a first data compute node (DCN) to forward outgoing traffic to a second DCN directly in spite of receiving the incoming traffic from the second DCN through a load balancer. That is, the return traffic's network path from the first DCN to the second DCN bypasses the load balancer, even though a request that initiated the return traffic is received through the load balancer. The method receives a first data message from a load balancer to be sent to a DCN. After identifying a particular address embedded in the data message by the load balancer, the method generates a table entry, based on source and destination addresses of the data message and the identified address. This entry is used for modifying a source address of a subsequent data message received from the DCN in response to the data message. |

Gas-gap devices are separately set between branching channels and inlet and outlet manifolds of positive and negative electrodes. Each of the branching channels separately has an inserting tube to be inserted into one of the gas-gap devices. The diameter of the inserted vessel of gas-gap devices is bigger than the diameter of the inserting tube connected to a corresponding one of the branching channels. Thus, working liquids transferred to the positive and negative electrodes are segregated with coordination of the gas-gap devices. Only air spaces and discrete liquid drops are left between separated parts of the working liquids. Thus, shunted currents are repressed by preventing conductive paths from being formed between the positive and negative electrodes. |

Method of forming tunable resistor with curved resistor elements
A resistor structure is provided that contains curved resistor elements. The resistor structure is embedded within an interconnect dielectric material and the resistivity of an electrical conducting resistive material of the resistor structure can be tuned to a desired resistivity during the manufacturing of the resistor structure. Notably, an electrical conducting metallic structure having a concave outermost surface is provided in a dielectric material layer. A doped metallic insulator layer is formed on the concave outermost surface of the metallic structure. A controlled surface treatment process is then performed to an upper portion of the doped metallic insulator layer to convert the upper portion of the doped metallic insulator layer into an electrical conducting resistive material. An interconnect dielectric material can then be formed to embed the entirety of the remaining doped metallic insulator layer and the electrical conducting resistive material. |
