Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters

Topology-Related Parameters

Topology-Related Parameters

Refer to the following sections to determine the correct values for all topology-related parameters before beginning to run the initial setup of the Cisco SCE8000.

•Connection Mode Parameter, page 3-11

•Physically Connected Links Parameter, page 3-12

•Priority, page 3-12

•On-Failure Mode Parameter, page 3-12

There are four topology-related parameters:

•Connection mode — Can be any one of the following, depending on the physical installation of the Cisco SCE8000 (Refer to Connection Mode Parameter, page 3-11):

–Inline — single Cisco SCE8000 inline

–Receive-only — single Cisco SCE8000 receive-only

–Inline-cascade — two inline Cisco SCE8000 platforms cascaded

–Receive-only-cascade — two receive-only Cisco SCE8000 platforms cascaded

•Physically-connected-links— In cascaded configurations, this parameter defines the number of the link connected to the Cisco SCE8000 platform being configured. (Refer to Physically Connected Links Parameter, page 3-12.)

It is applicable only in a cascade topology.

•Priority — This parameter defines which is the primary Cisco SCE8000 (Refer to Priority, page 3-12.)

It is applicable only in a cascade topology

•On-failure— This parameter determines whether the system cuts the traffic or bypasses it when the Cisco SCE8000 either has failed or is booting. Traffic bypass can be achieved either through the external optical bypass device or through the internal bypass mechanism of the SPA interface processor. It is not applicable to receive-only topologies. (Refer to On-Failure Mode Parameter, page 3-12.)

These parameters are configured via the connection-modecommand.

Connection Mode Parameter

The connection mode parameter refers directly to the physical topology in which the Cisco SCE8000 is installed. The connection mode depends on two factors:

•Inline/Receive-only:

–Inline — The Cisco SCE8000 resides on the data link between the subscriber side and the network side, thus both receiving and transmitting packets.

–Receive-only— The Cisco SCE8000 does not reside physically on the data link. Data is forwarded to the Cisco SCE8000 via an external optical splitter. The Cisco SCE8000 itself receives only and does not transmit.

•Cascade — Indicates a two Cisco SCE8000 topology where the two Cisco SCE8000 platforms are connected via the cascade ports.

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.
