Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Physical Topologies

Type of SCE Platform Redundancy

All Active

All ports in the EC and all SCE platforms are active. If there is a failure in one of the SCE platforms, the links on the related ports in the EC will be down and the EC will automatically exclude it from the load distribution. The load will then be distributed between the remaining active SCE platforms.

Since the Cisco SCE8000 supports two links, this configuration requires one SCE platform per two links (two EC ports).

N+1

'N' SCE platforms are active and one platform is on standby. The EC ports connected to the standby SCE platform must be configured as standby ports. In the case of failure of one of the SCE platforms, the EC ports connected to the failing SCE platform are shut and the standby EC ports, connected to the standby SCE platform, will be activated.

Since the Cisco SCE8000 supports two links, this configuration requires one SCE platform per two links (two EC ports), plus one extra SCE platform for standby.

Note that the standby SCE platform must be connected to the two highest-numbered ports, since EC behavior automatically designates these as the standby ports.

Redundant Cisco 7600 Series Router

Two Cisco 7600 Series routers can be used to provide network redundancy.

In this topology, one link on each Cisco SCE8000 platform is connected to each router. Therefore, one SCE platform is required for each link.

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.
