With the explosion of video traffic and social networking applications, speed and scalability are critical factors to keeping consumers happy. Cisco's Visual Networking Index (VNI) forecasts that by 2013, annual global IP traffic will reach two-thirds of a zettabyte (one trillion gigabytes), video traffic will exceed 90 percent of global consumer traffic, and global online video will comprise 60 percent of consumer Internet traffic (up from 32 percent in 2009).
As consumer demand for high-quality media on any device grows daily, cable operators are considering new intelligent solutions for their medianets (all-IP Next-Generation Networks optimized for rich media).
Cisco provides an end-to-end, DOCSIS
® 3.0-capable solution enabling multiple services to multiple devices over the same infrastructure to both residential and commercial subscribers.
This solution will allow service providers to provide subscribers with the best possible quality of experience, while minimizing operating expenses and differentiating next-generation services from those of their competitors.
Cisco's DOCSIS 3.0 solution with the Cisco
® uBR-MC88V Broadband Processing Engine (BPE) delivers
faster speeds and higher density with a flexible and scalable architecture. The resulting benefits are
faster time to market, lower total cost of ownership, and
higher revenues than previously possible, thus helping operators prepare their networks for the exponential growth of IP traffic.
The Cisco uBR-MC88V, Figure 1, is a next-generation line card for the Cisco uBR7200 Series Universal Broadband Router. It supports an unprecedented array of capabilities that address the needs of cable operators, multiunit (MxU) businesses, and Internet service providers (ISPs) to cost-effectively deliver high-bandwidth, carrier-class IP-based data, voice, and video services to large number of subscribers. The line card meets full DOCSIS 3.0 Annex A and B requirements. With this next-generation line card, the Cisco uBR7200 Series Universal Broadband Router has become the most advanced and ideal platforms for entry or mid-level cable modem termination systems (CMTSs) today.
The Cisco uBR-MC88V is capable of eight downstream (Annex A or Annex B) and eight upstream channels. The port count remains exactly the same as the Cisco uBR-MC28U, with two downstream ports and eight upstream ports. This enables the Cisco uBR-MC88V to offer a simple upgrade path from the older line card used on the Cisco uBR7200VXR platform without any change to the cable wiring. Each downstream port is capable of carrying four frequency-stacked downstream channels. Each downstream channel is configurable as part of DOCSIS 3.0 channel bonding or DOCSIS 2.0/1.x channel. The line card also supports an extended DOCSIS upstream frequency range of 5 to 65 MHz and downstream of 70 MHz to 1 GHz for DOCSIS operations.
Features and Benefits
Fully DOCSIS 3.0 Capable
® and EuroCableLabs DOCSIS 3.0 capable, the Cisco uBR-MC88V supports downstream and upstream channel bonding at a DOCSIS line rate that enables cable operators to offer very high-speed data services to subscribers. The line card supports bonding of 4, 8, and even more channels and other full DOCSIS 3.0 features including IPv6, multicast, Advanced Encryption Standard (AES) encryption, and Synchronous Code Division Multiple Access (S-CDMA).
High Port Density
The Cisco uBR-MC88V supports eight DOCSIS 3.0 downstream channels through two quad-stacked physical connectors and eight upstream channels each on a unique physical connector. It significantly expands the capacity of the Cisco uBR7200 Series Universal Broadband Router to address growing subscriber bandwidth demands and enable cost-effective scalability of services.
Superior RF Performance
The line card is compliant with DOCSIS Downstream RF Interface (DRFI) specifications and is designed with an extended frequency range up to 1 GHz by using a highly integrated and low-power-consumption upconverter. With the advanced spectrum management, ingress cancellation, and S-CDMA, the Cisco uBR-MC88V will mitigate ingress noises in the hybrid fiber/coaxial (HFC) plant to achieve better RF performance.
Rich Cisco Technology-Specific Features
The line card supports Cisco technology-specific features such as Dynamic Bandwidth Sharing (DBS), advanced spectrum management, and Subscriber Traffic Management (STM). DBS is the dynamic allocation of bandwidth for wideband and integrated cable interfaces sharing the same downstream channel, which allows each channel to claim the bandwidth unused by others. The DBS feature interacts with DOCSIS 2.0 load balancing to fully utilize bandwidth resources. The STM feature allows service providers to identify and control subscribers who exceed the maximum bandwidth allowed under their registered quality of service (QoS) profiles. This feature helps ensure that a minority of users will not consume a majority of the bandwidth in the cable network.
