Abstract: Measures for use in routing data in a data communications network. A request to route data to a given destination in the network is received. A route to the given destination is first selected from a plurality of routes to the given destination stored in a routing table. Routing the data to the given destination using the first selected route is attempted. In response to receipt of an indication that routing the data to the given destination via the first route failed, a second, different route to the given destination is second selected from the plurality of routes to the given destination stored in the routing table. The second selecting includes omitting, for the purposes of the second selection, at least one route to the given destination from the plurality of routes to the given destination stored in the routing table.
