摘要： Measures, including methods, apparatus and computer programs, for use in operating a network node. A method includes, at the network node: receiving a session initiation protocol (SIP) message directed towards a downstream network element, wherein the received message comprises session description protocol (SDP) data indicating a first SDP preconditions setting; forwarding the received SIP message on to the downstream network element with no modifications; in response to forwarding the received SIP message, receiving a rejection message from the downstream network element; on the basis of the received rejection message, determining that the first SDP preconditions setting is not supported by downstream device; generating a second SIP message comprising SDP data indicating a second SDP preconditions setting different from the first SDP preconditions setting; and transmitting the generated second SIP message comprising SDP data indicating the second SDP preconditions setting to the downstream network element.

摘要： A first finite resource allocation request is received at a finite resources allocation server from a first client network node requesting a first amount of a given type of finite resource for use by the first client network node. A first allocated amount of the given type of finite resource is first allocated to the first client network node. The first allocating allocates the first allocated amount at least on the basis of a previously allocated first amount. A second finite resource allocation request is received at the finite resources allocation server from a second client network node requesting a second amount of the given type of finite resource. A second allocated amount of the given type of finite resource is second allocated to the second client network node. The second allocating allocates the second allocated amount at least on the basis of a previously allocated second amount.

摘要： 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.
