摘要： A switching matrix (30) connects to an access network (10) and a set of at least two operator networks (41). A controller (51) performs a method of establishing new connections across the switching matrix (30) in response to new connection requests. The new connection requests involve a sub-set of the set of operator networks. The controller determines (103) if the new connections can be established across the switching matrix by rearranging only existing connections across the switching matrix to the sub-set of operator networks and, in response, establishes (104) the at least one new connection. Otherwise, the controller rearranges (105) existing connections across the switching matrix to at least one other of the set of operator networks to establish the new connections. The controller (51) minimises the number of other operator networks which are involved when rearranging existing connections. The switching matrix can be a Clos switching matrix.

摘要： A packet switching node is coupled by links to other nodes of a network, and receives and assembles (74) packets belonging to a specified packet flow, into bursts of packets with a burst control packet indicating a sequence of the burst in the flow. The node determines (78) whether to distribute the flow across several links. If so, the bursts are then forwarded (80) for switching to the output ports (160) of the selected links. Distributing the flow over multiple links can enable more flexible and efficient filling of allocated bandwidth on links, as traffic increases. To reduce the risk of losing the order of packets the sequence of the bursts is indicated for use in reordering at intermediate nodes during transmission through the network.
摘要翻译：分组交换节点通过链路耦合到网络的其他节点，并且将属于指定分组流的分组接收并组装（74）分组的分组，其中突发控制分组指示流中的突发的序列。节点确定（78）是否将流量分布在多个链路上。如果是，则突发脉冲被转发（80）以切换到所选链路的输出端口（160）。随着流量的增加，分布在多个链路上的流可以使链路上分配的带宽更灵活和高效地填充。为了降低分组丢失的风险，在通过网络的传输过程中，突发的序列被指示用于中间节点的重新排序。

摘要： A packet forwarding node (20) of a transport network (10) performs a first packet forwarding mode in which received packets (51) are processed and forwarded on a per- packet basis. The forwarding node performs a second packet forwarding mode when the node identifies a group (50) of consecutive packets (51). The group of packets are destined for the same destination node of the transport network (10). The second packet forwarding mode comprises determining a forwarding treatment for the group of packets (51) and forwarding the group of packets with the determined treatment. The forwarding is performed without processing the headers (52) of at least some of the packets in the group. The group (50) of consecutive packets (51) is identified by a control packet (60) preceding the group (50) or by inter-packet signalling (53) which indicates that the packet before the inter-packet signalling and the packet after the inter-packet signalling are to be treated as part of the same group. Packets which are determined to be received on transit channels can be forwarded without processing headers of individual packets.
