Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Topology-Related Parameters

The connection mode parameter is determined by the physical deployment of the Cisco SCE8000, as follows:

Single Cisco SCE8000 inline installation = Inline connection mode.

Single Cisco SCE8000 optical splitter installation = Receive-onlyconnection mode.

Two-platform cascaded Cisco SCE8000 inline installation = Inline-cascadeconnection mode.

Two-platform cascaded Cisco SCE8000 optical splitter installation = Receive-only-cascadeconnection mode

Physically Connected Links Parameter

A cascade topology supports two traffic links. This parameter defines which link is connected to which Cisco SCE8000 platform. The links are designated as follows:

Link 0

Link 1

Priority

In a cascade topology, the user must define the priority of each Cisco SCE8000.

Primary — The Primary Cisco SCE8000 is active by default

Secondary — The Secondary Cisco SCE8000 is the default standby.

Note that these defaults apply only when both devices are started together. However, if the primary Cisco SCE8000 fails and then recovers, it will not revert to active status, but remains in standby status, while the secondary device remains active

On-Failure Mode Parameter

The on-failuremode parameter configures the action taken by a failed box when a failure is detected.

As described in the section Internal Bypass Mechanism, page 3-9, the SPA Interface Processor card supports three different modes. The Bypass and Cutoff modes are possible when the Cisco SCE8000 is not operational due to platform failure or boot. The Forwarding mode enables control of traffic flow and is not compatible with the non-operational status.

The following on-failuremodes are possible:

Bypass — The SPA interface card forwards traffic between the two ports of each link with no intervention of the control application running in the Cisco SCE8000 platform. This is also known as 'electrical bypass'.

In a cascade setup, this allows the traffic of the link connected to the failed box to be passed to the active box for processing.

Cutoff — There is no forwarding of traffic. The link is forced down, resulting in traffic cutoff at Layer1.

External-bypass– The external optical bypass device is used to bypass traffic, maintaining link continuity at all times.

SCE8000 specifications

Cisco Systems SCE8000 is an advanced service control edge solution designed to enhance the management and performance of service provider networks. Targeted at carriers and large enterprises, the SCE8000 is characterized by its capacity to efficiently handle traffic management, quality of service (QoS), and policy enforcement across various services including voice, video, and data.

One of the main features of the SCE8000 is its scalability. The platform supports a high-density architecture, allowing service providers to seamlessly expand their networks to accommodate growing traffic demands. This scalability is complemented by an impressive throughput, which enables the handling of millions of concurrent sessions, making it ideal for environments with significant user activity.

The SCE8000 employs advanced traffic management capabilities, leveraging deep packet inspection (DPI) technology. This allows for granular visibility into network traffic, enabling service providers to make informed decisions about resource allocation and policy application. Additionally, the device supports multiple protocol analysis, ensuring compatibility across various network services and enhancing overall efficiency.

Quality of Service (QoS) is another critical characteristic of the SCE8000. The platform provides sophisticated mechanisms to prioritize traffic, thereby ensuring that delay-sensitive applications such as VoIP and video streaming receive the necessary bandwidth. This capability is enhanced by Cisco's intelligent traffic shaping and congestion management features, which work together to optimize the user experience even in congested network conditions.

The SCE8000 also integrates robust security features, including session initiation protocol (SIP) security, to protect against malicious attacks and maintain service integrity. This is particularly important in today's cyber landscape where service providers must safeguard their infrastructure from various threats.

Automation and programmability are essential characteristics of the SCE8000, enabling operators to implement policies quickly and efficiently. This feature allows for dynamic scaling and rapid deployment of new services, significantly reducing the time to market for new offerings.

In conclusion, Cisco Systems SCE8000 stands out as a powerful platform for managing service provider networks. With its high scalability, advanced traffic management, quality of service assurance, robust security features, and automation capabilities, the SCE8000 enables service providers to deliver a superior customer experience while optimizing their operational efficiency. This makes it an invaluable asset for any organization looking to enhance its network performance and service delivery.
