The actual site that serves the Web pages to a client in response to a URL domain name is automatically and transparently selected from a list of many switches each having identical data storage. In a peer hand-off process, a switch receives domain name server lookup request for a particular virtual Internet protocol (VIP) domain name. The switch examines the source IP-address for the domain name server request, examines the user's IP-address, and determines if there is server site that is geographically close to that user. The switch examines an ordered hand-off table corresponding to the domain. The switch chooses a next remote server (or its own VIP) in line based on, (a) the remote server location compared to domain name server request source, (b) the remote servers' weights, and (c) the remote server that experienced the previous hand-off. The switch then sends the domain name server response back to client domain name server with the IP-addresses in an ordered list.

A data processing apparatus communicates data bits on a predetermined number of sub-carrier signals of an Orthogonal Frequency Division Multiplexed (OFDM) symbol. The data processing apparatus comprises a parity interleaver operable to perform parity interleaving on Low Density Parity Check (LDPC) encoded data bits obtained by performing LDPC encoding according to a parity check matrix of an LDPC code including a parity matrix corresponding to parity bits of the LDPC code, the parity matrix having a stepwise structure, so that a parity bit of the LDPC encoded data bits is interleaved to a different parity bit position. A mapping unit maps the parity interleaved bits onto data symbols corresponding to modulation symbols of a modulation scheme of the OFDM sub-carrier signals. A symbol interleaver is arranged in operation to read-into a symbol interleaver memory the predetermined number of data symbols for mapping onto the OFDM sub-carrier signals, and to read-out of the interleaver memory the data symbols for the OFDM sub-carriers to effect the mapping, the read-out being in a different order than the read-in, the order being determined from a set of addresses, with the effect that the data symbols are interleaved on the sub-carrier signals. The set of addresses are generated by an address generator which has been optimised to interleave the data symbols on to the sub-carrier signals of the OFDM carrier signals for a given operating mode of the OFDM system, such as a 32K operating mode for DVB-T2 or DVB-C2.
