For instance, SATA revision 3.0 (6 Gbit/s) controllers on one PCI Express 2.0 (5 Gbit/s) channel will be limited to the 5 Gbit/s rate and have to employ more channels to get around this problem. Early implementations of new protocols very often have this kind of problem.
Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
OC-48 is a network line with transmission speeds of up to 2488.32 Mbit/s (payload: 2405.376 Mbit/s (2.405376 Gbit/s); overhead: 82.944 Mbit/s). With relatively low interface prices, with being faster than OC-3 and OC-12 connections, and even surpassing gigabit Ethernet, OC-48 connections are used [when?] as the
Beginning with the donation of the PL-3 interface by PMC-Sierra in 2000, the OIF produced the System Packet Interface (SPI) family of packet interfaces. SPI-3 and SPI-4.2 defined two generations of devices before they were supplanted by the closely related Interlaken standard in the SPI-5 generation in 2006.
A cyclic transmission of up to 32 bytes per participant is possible. An acyclic parameter channel with up to 256 bytes is available for each device as well. ASi-5 is to provide a set of up to 1536 binary inputs and 1536 binary outputs per Ethernet address. 1.2 ms cycle time can be achieved by the system for up to 24 participants.
The agreements are: SPI-3 – Packet Interface for Physical and Link Layers for OC-48 (2.488 Gbit/s) [1]; SPI-4.1 – System Physical Interface Level 4 (SPI-4) Phase 1: A System Interface for Interconnection Between Physical and Link Layer, or Peer-to-Peer Entities Operating at an OC-192 Rate (10 Gbit/s).
V5.2 (ETS 300 347-1) which provides for concentration where there are not enough bearer channels in the aggregate link(s) to accommodate all subscribers at the same time. A single V5.2 interface can control up to 16 E1 links at once and can include protection of the signalling channels.
