A wide range of network interfaces and advanced traffic management features allow you to build an ATM WAN over the most economic infrastructure, whether it's coaxial cable, fiber, satellite, or microwave. At the cornerstone of your ATM network, the BPX 8600 series can be rapidly deployed, reducing time to market.

Intelligent QoS Management Features Enable Service Differentiation

With the Cisco BPX 8600 series, you can provide service-level guarantees for any type of traffic or application—ATM, Frame Relay, Internet, voice over IP, VPN, video, and voice. Cisco's Intelligent QoS Management Suite includes the first fully compliant implementation of the ATM Forum's Traffic Management Standard Version 4.0 Specification. A sophisticated queuing architecture, QoS capabilities, and connection admission control (CAC) features work together to meet SLAs for any traffic type or application.

Automatic Routing Management

Cisco WAN switches use an end-to-end connection routing mechanism to provide connectivity across the network. Fully compliant Private Network-Network Interface (PNNI) routing via the Service Expansion Shelf and call signaling enable the creation of end-to-end SVC and SPVC connections—even in a multivendor network environment. Distributed network intelligence enables the switch's CAC function to work with advanced routing management features, automatically routing traffic through the network. If a link fails, the routing algorithm quickly and automatically reroutes connections over alternate paths while guaranteeing the required QoS. Automatic routing management ensures high service availability and QoS for all data services. PNNI routing allows you to scale networks to thousands of routing nodes with the same level of routing reliability.

The virtual trunking capability of the BPX 8600 ensures that Cisco's intelligent QoS features are extended edge to edge. Cisco BPX 8600 series switches can be interconnected through an ATM-virtual path (VP) crossconnect or large ATM core switch. As a result, each user connection on BPX 8600 switches receives the nonstop service availability, high application performance, and outstanding QoS characteristics of a Cisco BPX-based network.

Advanced Class-of-Service Management

Class-of-service management is essential for delivering the required QoS to all applications, and the BPX 8600 series supports up to 16 independent classes of service. Per-virtual circuit (VC) queuing, per-VC rate scheduling, a sophisticated queue-servicing algorithm, and egress queuing enable network managers to tailor individual connections to meet service-level guarantees for ATM classes of service. IP traffic is assigned its own classes of service, allowing network managers to easily manage both types of traffic over the same network.


Figure 5: Virtual trunking interconnects BPX 8600 nodes via an ATM core switch, yet retains the QoS performance of the BPX 8600.


Optimized Bandwidth Management

The BPX 8600 employs a virtual source/virtual destination (VS/VD) implementation of the ATM Forum Traffic Management Standard Version 4.0 for ABR services. The switch continuously monitors trunk utilization throughout the network and feeds congestion information back to the traffic source. Cell admission rates are automatically adjusted on a connection-by-connection basis, depending on whether and where congestion exists on the network, ensuring fair and cost-efficient bandwidth utilization. The robust VS/VD implementation proactively avoids queuing delays and virtually eliminates cell loss. Cisco's ForeSight® software provides VS/VD capability for Frame Relay traffic, resulting in the same high levels of bandwidth utilization and superior throughput and latency for Frame Relay customers.

Built into custom application-specific integrated circuits (ASICs), per-virtual connection control capabilities manage queuing, rate scheduling, statistics collection, and fair allocation of bandwidth on an individual-connection basis. Up to 32,000 connections and one million cells of buffering are supported on each interface card. The BPX 8600 supports early packet discard (EPD) and partial packet discard (PPD) on a per-VC basis, resulting in fewer retransmissions than class-based implementations. As a result, the BPX 8600 series delivers high application performance and guaranteed network responsiveness for all users.

Cisco's optimized bandwidth-management capabilities enable you to typically achieve 95-percent trunk utilization—the highest in the industry. At the same time, VS/VD, ABR, and ForeSight technology significantly improve application throughput, ensuring real-time application performance and increased customer satisfaction.

Dynamic Buffer Management

Cisco Frame Relay and ATM service modules are equipped with large buffers and a patented dynamic buffer management algorithm mechanism for allocating buffers on a per-VC basis to deliver the required QoS. This deep pool of available buffers readily accommodates large bursts of traffic into the node. BPX 8600 series ATM interface modules provide up to a million cells of buffering.


Figure 6: Per-virtual-circuit queuing and rate scheduling proactively avoid congestion to deliver the highest levels of application throughput and lowest latency—
virtually eliminating cell loss.


High Reliability Ensures Nonstop Service Availability

Proven in the world's largest production ATM and Frame Relay networks, the BPX 8600 series is designed for carrier-class reliability. Every system component can be configured for 100-percent redundancy, and all BPX 8600 series modules can be removed and reinserted without impacting service delivery or affecting the performance of other modules. Background diagnostics continually monitor switch functions on active, as well as standby modules, ensuring fault-tolerant operation. The result? Cisco wide-area switches routinely deliver 99.999-percent service availability, leading to high user satisfaction and reduced subscriber churn.

Hot-Standby Interfaces

Hot-standby interfaces offer optional redundancy, so if a module fails, the standby is fully on line within milliseconds. Switchover to standby interfaces is non-service affecting for most protocols, ensuring nonstop high application performance.

Automatic Protection Switching

The Cisco BPX 8600 series supports industry-standard, automatic protection switching (APS) for Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) interfaces. Both 1+1 and 1:1 APS schemes are supported. If a fiber is cut or a card fails, APS performs switching to the backup fiber within milliseconds.

Automatic Rerouting

If a trunk fails, the automatic connection-management feature of the BPX 8600 automatically reroutes virtual circuits. This same automatic connection-routing algorithm is incorporated in Cisco's network modeling software, allowing you to design highly reliable networks that can withstand almost any combination of link failures. Modeling-simulation features allow you to design and test a network, using what-if scenarios to assess the impact of potential link failures. The result is a stronger network design and the industry's highest service availability.

Non-Service Affecting Software Upgrades

Non-service affecting software upgrades allow you to gracefully upgrade software or add new features without disrupting services. Customers receive the benefits of new features without interrupting service delivery or application performance.

Scalability Lets You Grow Your Network Gracefully

The unmatched scalability of the BPX 8600 lets you stay ahead of exploding demand without requiring significant reinvestment in your network infrastructure. With the industry's highest port density, the BPX 8600 series switch supports up to 96 OC-3/STM-1 port interfaces or up to 144 T3/E3 port interfaces. Custom ASICs deliver the industry's most advanced ATM capabilities and highest port densities, slashing the average price per port for high-speed connections by more than 50 percent over previous solutions. As a result, the BPX 8600 series delivers the highest performance at the lowest cost per user in the industry.

Each BPX 8600 series switch supports thousands of broadband and narrowband connections, enabling you to add subscribers as demand increases. Up to 16 edge concentrator shelves allow you to easily add capacity as service demand grows. A fully configured BPX 8600 can support tens of thousands of subscribers.
