Data Compression AIM for the Cisco 3660 series

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 platform`s 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.

Key Benefits

• Maximizes System Resources

  • Frees the platform`s CPU for other routing tasks, improving performance

  • Provides simultaneous support for multiple circuits

  • Provides maximum compression performance where required

• Reduces Costs

  • Reduces packet traffic on a link when tariffing is usage based (resulting in WAN cost reduction)

  • Shrinks frame lengths, allowing more data to be transmitted using the same amount of bandwidth and reducing the need for costly additional WAN links or circuits

  • Enables customers to deploy additional services such as voice/data integration without increasing bandwidth

• Improves WAN Bandwidth Efficiency

  • Maximizes WAN data throughput on all WAN interfaces (avoiding the expense of additional or higher-speed links)

  • Improves application response time on congested links

  • Maximizes the advanced bandwidth management capabilities of Cisco IOS

• Improves Branch-Office Network Manageability

  • Eliminates costly external third-party products

  • Single management view for platform and compression services

• Supports Industry Standards

  • STAC (QIC122) compression algorithms

  • Microsoft Point-to-Point Compression algorithm

  • FRF.9 Frame Relay Payload Compression

  • Compression Control Protocol (CCP) RFC
