A network is accessed. The network comprises a plurality of tiles. Each tile in the plurality of tiles includes a mesh switching unit. A communication packet is received by a first tile within the plurality of tiles. The communication packet specifies a target tile within the network. The first tile and the target tile are not adjacent within the network. The communication packet includes a first routing. The first routing includes a first intermediate tile within the plurality of tiles. A second routing is determined by the first tile. The second routing is based on a second intermediate tile within the plurality of tiles. The communication packet is sent by the first tile to the first intermediate tile. The sending includes the second routing. The process continues until the communication packet reaches the target tile within the network.
