Abstract: The techniques are provided automatically detecting when performing pre-transmission compression on data to be sent over a network connection will be preferable to sending the data uncompressed, and for automatically performing pre-transmission compression only when doing so is determined to be beneficial. The techniques involve performing compression on sample data. The time it takes to perform the compression on the sample data, along with the reduction in size achieved by the compression, are factors used to automatically determine whether compressing data before sending the data over a network connection will achieve better results that sending the data uncompressed. In some embodiments, multiple compression algorithm/compression level combinations are tested at different points in the transmission. At each point, the sending device may switch to the algorithm/level combination that is producing the best results on the current sample.

Abstract: A method, a device and a system for interconnecting a multi-protocol label switching (MPLS) network and an Ethernet are provided. A packet sent by a node located at the Ethernet is received, the packet is parsed, the parsed packet is re-encapsulated by means of MPLS, and the re-encapsulated packet is sent to a node located at the MPLS network, so as to implement interconnection between the MPLS network and the Ethernet. A reverse solution is similar to this. An intermediate node in the solution adopts a manner of parsing a packet and then re-encapsulating the packet when the packet is sent from one network to another network, instead of transparent transmission only. Therefore, it is unnecessary to configure a Media Access Control (MAC) address of a remote node on a node located at the Ethernet and to configure Ethernet information on a node located at the MPLS network.

Abstract: A method for mapping a physical hybrid automatic repeat request indicator channel (PHICH) is described. The method for mapping a PHICH includes determining an index of a resource element group transmitting a repetitive pattern of the PHICH, according to a ratio of the number of available resource element groups in a symbol in which the PHICH is transmitted and the number of available resource element groups in a first or second OFDM symbol, and mapping the PHICH to the symbol according to the determined index. In transmitting the PHICH, since efficient mapping is performed considering available resource elements varying with OFDM symbols, repetition of the PHICH does not generate interference between neighbor cell IDs and performance is improved.
