The need for speed is everywhere. Internet Protocol (IP) has become tremendously important for combining data, voice and video in the same data stream. Different networks, like IMS (Internet Protocol Multimedia Subsystem), VoIP (Voice-over-Internet Protocol), Mobile VoIP, and others use the same protocol for these data packages-referred to as converging networks. Mobile data services require a higher aggregate bandwidth for network elements like base stations, radio network controllers and core networks, which have to accommodate this increased data traffic. What started as a gradual trend to higher bit rates accelerated dramatically in 2004 with the introduction by Intel of the PCI Express standard. Following Intel's lead, the majority of chip-to-chip connection standards underwent an architectural shift from parallel busses to serializer/deserial-izer (SERDES) links, called "lanes."
