Description:

Data compression reduces the size of data frames to be transmitted over a network link, thus reducing the time required to transmit the frames across the network. Data compression works by providing a coding scheme at each end of a transmission link that allows characters to be removed from the frames of data at the sending side of the link and then replaced correctly at the receiving side. Because the condensed frames take up less bandwidth, more frames can be transmitted per unit of time. Data compression schemes used in internetworking devices are referred to as loss less compression algorithms. These schemes reproduce the original bit streams exactly, with no degradation or loss, a feature required by routers and other devices to transport data across the network. The two most commonly used compression algorithms on internetworking devices are the Stacker compression and the Predictor data compression algorithms.The CSA provides high-performance, hardware-based, data compression capabilities. The CSA faceplate has no media interfaces. The CSA offloads all compression- and decompression-related packet handling from host processors by compressing and decompressing packets passing through interfaces on serial port adapters. The CSA supports simultaneous Stacker data compression algorithms, with independent full-duplex compression and decompression capabilities. The CSA supports only PPP and Frame Relay encapsulation.This compression module uses 256 VCs Stac algorithm. Based on the Lempel-Ziv compression algorithm, stacker compression was developed by STAC Electronics. The Stacker algorithm uses an encoded dictionary that replaces a continuous stream of characters with codes. The symbols represented by the codes are stored in memory in a dictionary-style list. Because the relationship between a code and the original symbol varies as the data varies, this approach is more responsive to variations in the data. This flexibility is particularly important for local-area network (LAN) data, because many different applications can be transmitting over the wide-area network (WAN) at any one time. In addition, as the data varies, the dictionary changes to accommodate and adapt to the varying needs of the traffic.

Description:

The data compression advanced integration module (AIM) for the Cisco 3660 series delivers a cost-effective option for reducing recurring wide-area network (WAN) costs and maximizing the benefit of the advanced bandwidth management features of Cisco IOS. The data compression AIM takes advantage of either of the two available Cisco 3660 internal AIM slots, ensuring that external slots remain available for components such as integrated analog voice/fax, digital voice/fax, ATM, channel service unit/digital service units (CSU/DSUS), analog and digital modems.Data compression technology maximizes bandwidth and increases WAN link throughput by reducing frame size and thereby allowing more data to be transmitted over a link. This feature enables network managers to increase application performance and service availability for end users without costly infrastructure upgrades. Data compression enables service providers to maximize available bandwidth and deliver more services to customers over their existing infrastructure-enhancing their return on investment. While software-based compression capabilities can support fractional T1/E1 rates, hardware based compression off-loads the platforms main processor to deliver even higher levels of throughput. With a compression ratio of up to 4: 1, the Data Compression AIM supports 16 Mbps of compressed data throughput without imposing additional traffic latency-enough to keep four T1 or E1 circuits full of compressed data in both directions simultaneously. And because the Data Compression AIM is fully integrated with the Cisco 3660, network managers are not forced to provision and manage a separate external device at a remote site. The Data Compression AIM supports industry standard LZS and Microsoft Point-to-Point Compression (MPCC) algorithms and ensures compatibility with all Cisco products supporting hardware or software based compression.

Description:

The SA-Comp/1 data compression service adapters (CSA) provide high-performance, hardware-based data compression capabilities via simultaneous Stacker compression data compression algorithms with independent full-duplex compression and decompression capabilities on point-to-point (PPP) encapsulated packets. The SA-Comp/1 supports up to 64 compression contexts. There is one compression context per PPP link.The CSA supports the compression and decompression of data passing through synchronous serial interfaces that are configured for a peak line rate of 16 Mbps or lower. You can use the CSA to compress and decompress data passing through any synchronous serial interface; however, the serial interface must be configured to send and receive data at a rate no greater than 16 Mbps. For example, the CSA supports high-speed serial interfaces (such as HSSI interfaces) if the interfaces are configured for a peak line rate of 16 Mbps or lower. On the Cisco 7200 series routers you can optionally specify which CSA the interface uses to perform hardware compression.
