A novel design of a gateway that handles traffic in and out of a network by using a datapath pipeline is provided. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall.

Logical router with multiple routing components
Some embodiments provide a method for handling failure at one of several peer centralized components of a logical router. At a first one of the peer centralized components of the logical router, the method detects that a second one of the peer centralized components has failed. In response to the detection, the method automatically identifies a network layer address of the failed second peer. The method assumes responsibility for data traffic to the failed peer by broadcasting a message on a logical switch that connects all of the peer centralized components and a distributed component of the logical router. The message instructs recipients to associate the identified network layer address with a data link layer address of the first peer centralized component. |

Multi-tenant throttling approaches
An opportunistic throttling approach can be used for customers of shared resources in a multi-tenant environment. Each customer can have a respective token bucket with a guaranteed fill rate. When a request is received for an amount of work to be performed by a resource, the corresponding number of tokens are obtained from, or charged against, a global token bucket. If the global bucket has enough tokens, and if the customer has not exceeded a maximum work rate or other such metric, the customer can charge less than the full number of tokens against the customer's token bucket, in order to reduce the number of tokens that need to be taken from the customer bucket. Such an approach can enable the customer to do more work and enable the customer's bucket to fill more quickly as fewer tokens are charged against the customer bucket for the same amount of work. |

Preventing TCP from becoming too conservative too quickly
A technique that addresses the problem of a TCP connection's throughput being very vulnerable to early losses implements a pair of controls around ssthresh. A first control is a loss forgiveness mechanism that applies to the first n-loss events by the TCP connection. Generally, this mechanism prevents new TCP connections from ending slow-start and becoming conservative on window growth too early (which would otherwise occur due to the early losses). The second control is a self-decay mechanism that is applied beyond the first n-losses that are handled by the first control. This mechanism decouples of ssthresh drop from cwnd and is thus useful in arresting otherwise steep ssthresh drops. The self-decay mechanism also enables TCP to enter/continue to be slow-start even after fast-recovery from a loss event. |

Electrically testable integrated circuit packaging
An extension of conventional IC fabrication processes to include some of the concepts of flip-chip assemblies while producing a final “non-flip chip” circuit structure suitable for conventional packaging or for direct usage by customers. Multiple IC dies are fabricated on a semiconductor wafer in a conventional fashion, solder bumped or the like, and singulated. The singulated dies, which may be of different sizes and functionality, are then flip-chip assembled onto a single tile substrate of thin-film material which has been patterned with vias, peripheral connection pads, and one or more ground planes. Once dies are flip-chip mounted to the thin-film tile, all of the dies on the entire tile may be probed using automated testing equipment. Sets of dies of different functionality may be tested as a system or subsystem. Once test probing is complete, the dies (or sets of dies) and tile are singulated into die/tile assemblies. |
