Cisco 8608 Router Data Sheet

 

Cisco 8000 overview

The Cisco^® 8000 Series combines the revolutionary Cisco Silicon One^™, IOS XR^® software, and clean sheet chassis design to deliver a breakthrough in high-performance routers. The 8000 Series comprises a full range of feature-rich and highly scalable and reliable routers. Cisco 8608 is a part of a new complimentary portfolio built on Centralized Architecture based chassis design.

The Cisco 8608 is a unique platform that combines flexibility and reliability while offering investment protection. Customers can achieve unmatched reliability with redundant control and data plane via redundant route processors and redundant switch cards. Unlike distributed architecture, the forwarding decisions on centralized platforms are centrally performed. Cisco 8608 can also be operated in a non-redundant mode as per the appropriate customer required use case. Cisco 8608 first generation switch cards are powered by Cisco Silicon One^™ Q200 ASIC. A wide variety of modular port adapters allow for high interface diversity.

This data sheet is specifically for the Cisco 8608 router. In addition to the centralized router architecture in the Cisco 8608, the Cisco 8000 Series includes two other distinct router architectures that utilize the Cisco Silicon One ASICs:

●     Distributed: The Cisco 8800 Series provides the highest bandwidth via distributed chassis with a redundant control plane and switch fabric. The 8800 Series includes the Cisco 8804, 8808, 8812, and 8818. These chassis deliver up to 28.8 Tbps per line card via 100, 400, and 800G ports.

●     Fixed: The Cisco 8100 and 8200 utilize Cisco’s standalone architecture to deliver full routing functionality with a single ASIC per router. Both support the full routing feature set. The 8200 has deep buffers and expanded forwarding tables, while the 8100 is targeted for data center applications with lower buffering and forwarding table scale requirements.

Cisco 8608 overview

Large, distributed chassis have traditionally been designed to cater to the market requirement for total system bandwidth, port diversity, and redundancy. The requirements far exceeded what could be accomplished with a single NPU. The fabrics that weave together multi-NPU systems had to be provisioned to the highest bandwidth use case and deployed 100% upfront, consuming power and capital regardless of the number of installed line cards. That wisdom held true for multiple generations of core, edge, and aggregation distributed systems.

Now with the advent of dense Cisco Silicon One ASICs, we can address these roles with a new breed of centralized architectures that combine the best aspects of distributed and fixed systems. Cisco 8608 has combined the redundancy and I/O diversity of distributed systems with the economics and simple elegance of fixed platforms. As a result, Cisco 8608 delivers redundancy at an optimized cost while enabling flexibility and expandability through generational continuity.

The key chassis components and their overview is captured in the table below:

Silicon innovation with Cisco Silicon One ASIC

Cisco Silicon One^™ is Cisco’s first routing silicon architecture to break through the 10 Tbps benchmark for network bandwidth. This is accomplished without sacrificing route capacity, packet-per-second forwarding performance, or feature flexibility. The first-generation Cisco 8608 is driven by Q200 Cisco Silicon-One 7nm ASIC which delivers 12.8 Tbps of bandwidth and delivers high-scale routing and deep buffering using HBM (High bandwidth memory), thus avoiding any off-chip memory. HBM is connected via ultra-fast silicon interface and delivers significant performance at low power.

Cisco 8608 system design innovation

The 8608 chassis utilizes a state-of-the-art orthogonal design with advanced cooling via front to back airflow, high power capacity, and new power supplies. The chassis and all data path components for the Cisco 8608 benefit from a clean sheet design that allows the systems to take full advantage of the latest technologies and Cisco’s design expertise. This design connects all forwarding path components directly without a backplane or midplane. The eight Modular Port Adapters (MPAs) along with the two route processors are vertically oriented. Every major component of Cisco 8608 was designed from the ground up, thus representing unprecedented investment and commitment to a long lifecycle for the platform.

Cisco 8608 value proposition

Redundancy – Cisco 8608 introduces a new forwarding paradigm via a redundant control plane (route processor [RP] redundancy) and redundant data plane (switch card [SC] redundancy). A redundant 8608 requires two RPs and two SCs, while a nonredundant 8608 is comprised of a single RP and SC.

Investment Protection – The design of the system allows for upgrade of all the major components of the chassis such as the switch cards. This will ensure that customers’ investments into the commons are protected while Cisco launches next generation components.

Flexibility – Flexibility via MPA modularity and interface diversity. Native port speed support from 10GbE upto 400GbE. Wide variety of optics support for multiple customer use cases.

Cisco 8608 switch card

Cisco 8608 switch cards sit within the fan trays at the back of the fans. Each fan tray has four fan modules integrated with the switch card. There are two fan trays per chassis. The ASIC sits within the switch card, and all the forwarding decisions are driven by the switch card. Detailed characteristics of the switch card can be found in Table 3 below.

Security

Security is a major concern for all Cisco customers. Attacks on networking equipment can have disastrous results. Network operators need assurance that the platform is secure against hardware and software breaches. The Cisco 8608 router supports hardware root of trust based on the Trusted Computing Group (TCG) and IEEE 802.1 AR standards. The Cisco 8608 is FIPS 140-2 Level 2 compliant and supports advance security features to ensure platform and OS integrity.

●     Cisco secures the supply chain of every system at manufacturing time. A technology called “Chip Protection” allows customers to be assured that the hardware they receive from Cisco has no counterfeit components. This is accomplished with the use of unique identifiers that are stored inside the Trusted Anchor Module (TAM) device to identify and track components through the entire lifecycle of the Cisco 8608. The checks cover all major components, including network processors, CPUs, and Field-Programmable Gate Arrays (FPGAs).

●     Every image that a customer downloads from the Cisco site is cryptographically signed using Cisco private keys. Each platform has a TAM (based on the TCG standard) that uses built-in cryptographic functions to validate the image signature. Once the signature is validated, the software is considered authentic and is ready for install.

●     During normal operation, the JTAG (Joint Test Action Group – a method of chip testing and verification) ports on the chips are monitored. JTAG is one of the most common attack surfaces and therefore must be secured. Cisco uses a technology called “Secure JTAG” to monitor the port. If any illegal activity is detected, it is flagged, and the system CPU is held in reset mode.

●     Secure Boot root of trust is anchored in the TAM. It establishes an authentication chain that validates the entire boot process.

Cisco IOS XR software

Cisco IOS XR is a unified network OS spanning access, aggregation, edge, and core. The networking protocol stack within XR can be cut down by two-thirds when the IP transport architecture is simplified. Improvements to XR internal architecture have reduced the memory footprint by 35 percent. By reducing code size and the resources required, XR can be installed onto even the most constrained hardware designs with full security features without impact to boot times.

Modernizing XR with install procedures using standard Linux software package managers has also improved operations. Instead of “one size fits all,” XR provides modularity, so customers only load what they will use.

Service providers can easily access new software packages from trusted Cisco RPM Package Manager repositories. Alternatively, they can build their own repository of both Cisco and custom software packages, which can be fetched for final system configuration without spending time trying to sort out software dependencies. All the required Cisco software packages, homegrown/third-party software packages, and router configurations can be pulled into a single Cisco software image known as a “Golden ISO.” Customized images can now be installed consistently and with confidence across devices in the network.

Cisco IOS XR brings an unmatched level of openness for programmability and customization.

IOS XR supports open, model-driven APIs at all layers of the software stack. At the management layer, XR supports a comprehensive list of both native and industry-driven OpenConfig models with multiple encoding (XML and JSON) and transport (gRPC, Netconf) options. The APIs at the management layer allow operators to apply configuration to the device or retrieve the state of the system. The APIs also address advanced traffic engineering use cases, allowing applications to control the route followed by traffic within the network. These APIs can be used independently or combined with other ecosystem abstraction layers such as SONIC or P4Runtime.

IOS XR also supports the OFA (Open Forwarding Abstraction) API, which provides a logical representation of all the forwarding and telemetry capabilities of the underlying hardware. In addition, IOS XR provides a flexible consumption model, allowing third-party application software to run on the device alongside IOS XR to enable customization options for the customer network. With application hosting capabilities, operators can host their own controller agent or custom protocol; use various hosting apps for telemetry collection, traffic engineering, and configuration management; or manage the box like a Linux machine using third-party software such as Chef, Puppet, or Ansible.

Cisco IOS XR is the industry’s most trusted network operating system.

XR is the most advanced network operating system for improving the security posture of the router. The Cisco Secure Boot subsystem ensures that the device boot image is genuine and untampered. With advanced signing technology, XR can establish software integrity enforcement and measurement. To further enhance the trusted defense posture, multiple runtime defenses within XR guard against malicious actors and make exploitation of bugs more difficult. Even if booted securely, a router may run for months or years without rebooting, which could leave vulnerabilities at runtime undetected for a long time. XR leverages Integrated Measurement Architecture (IMA) to significantly enhance security by verifying the integrity of running software. In the IMA appraisal mode, signature validations prevent unauthorized images to launch. In the IMA measurement mode, the hashes of all images are logged in a secure location used for verification. Records of run time processes can be sent for analysis, so the operator knows that system software, updates, or patches are running as intended.

Detailed information on IOS XR can be found in the IOS XR data sheet.
