Abstract: A packet according to a secure protocol over a high-speed protocol has a small size header. A reception system estimates a packet number which is used in processing of a packet having a small size header on the basis of information indicating a packet number of a received packet. The header of each of one or more packets among N packets (where N is an integer of two or more) is a small size header, which is either a first header having one part of the packet number of the packet or a second header without the packet number of the packet. When the small size header is the first header, the header of each of the N packets is the first header. When the small size header is the second header, the header of each of the packets other than one packet among the N packets is the second header.

Abstract: A method of operating a communications network is disclosed. Modern communications networks produce vast amounts of network operational data which have the potential to provide a useful summary of the operational state of the network. Whilst processes such as clustering are known for arranging the vast amount of data into groups, the clusters themselves do not provide data which might be easily interpreted by network elements or administrators. Network operational data often comprises a plurality of data items, each of which gives a value for each of a set of attributes. By processing a cluster to identify attributes in the cluster whose values vary less in the cluster then they vary outside of the cluster, and then generating a cluster description which is based on a measure of the central tendency of the values of those attribute in the cluster, an easily interpretable general description of the data items in the cluster is provided.
