Examples described herein relate to a packet processing device that includes a programmable packet processing pipeline that is configured using a virtual switch. In some examples, the programmable packet processing pipeline is to receive configurations from multiple control planes via the virtual switch to configure packet processing actions. In some examples, the virtual switch is to provide inter-virtual execution environment communications. In some examples, the programmable packet processing pipeline is configured using a programming language.

Systems and methods are provided for managing a data communication within a multi-level network having a plurality of switches organized as groups, with each group coupled to all other groups via global links, including: at each switch within the network, maintaining a global fault table identifying the links which lead only to faulty global paths, and when the data communication is received at a port of a switch, determine a destination for the data communication and, route the communication across the network using the global fault table to avoid selecting a port within the switch that would result in the communication arriving at a point in the network where its only path forward is across a global link that is faulty; wherein the global fault table is used for both a global minimal routing methodology and a global non-minimal routing methodology.

Techniques for operating a networking switch in two broadcast networks are provided. In some embodiments, the switch may instantiate a first controller client and a second controller client in a control plane of the switch; register the first controller client with a first broadcast controller associated with a first broadcast network; and register the second controller client with a second broadcast controller associated with a second broadcast network. The switch may further receive a first multicast route through the first controller client; receive a second multicast route through the second controller client; and program at least one of the first multicast route and the second multicast route into a multicast routing information base.

A system and method of dynamically mapping a network topology of a mesh network of nodes. The method including maintaining, by a processing device of a control node of the mesh network, a network topology map indicating groups of neighboring nodes. The method including determining that a first node of the mesh network discovered a neighbor change event associated with a second node. The method including identifying, based on the network topology map, a group of neighboring nodes of a target node of the mesh network responsive to determining that the first node detected the neighbor change event. The method including transmitting a targeted message to a first neighboring node of the group of neighboring nodes to cause the first neighboring node to notify the group of neighboring nodes of the neighbor change event.

Some embodiments provide a method for a computing device that implements a first logical network gateway in a first datacenter to process data messages between data compute nodes (DCNs) belonging to the logical network and operating in the first datacenter and DCNs belonging to the logical network and operating in a second datacenter. From a host computer in the first datacenter, the method receives a logical network data message encapsulated with a first tunnel header including a first virtual network identifier corresponding to a logical forwarding element of the logical network. The method removes the first tunnel header and encapsulates the logical network data message with a second tunnel header include a second virtual network identifier corresponding to the logical forwarding element. The method transmits the logical network data message encapsulated with the second tunnel header to a second logical network gateway in the second datacenter.

In some embodiments, a method adds a specific route for an IP address that is associated with a first workload into a routing table for a first network device in a first site in response to the first workload being migrated from a second site to the first site. The first network device receives a packet from a second workload for the first workload and determines that a destination of the packet matches the specific route in the routing table. The method routes the packet from the second workload to the first workload using the specific route in the routing table without sending the packet to the second site.
