Appendix A The External Optical Bypass Module

External Optical Bypass Functionality

External Optical Bypass Functionality

The External Optical Bypass module is connected bump-in-the-wire in the GBE link. It is then connected to the SCE 2000 platform with two types of connections:

•GBE optical connections for data link traffic: GBE connections from the External Optical Bypass module to one pair of the GBE line ports.

•Power and Control connection: Connection to a dedicated connector on the SCE 2000 platform back panel, so the SCE 2000 platform can provide power to the External Optical Bypass module. (Note that the power connection also provides the logical control functionality.)

The External Optical Bypass module is normally inactive, (not in bypass), and simply transfers the two GBE signals to and from the SCE 2000 platform.

In case the SCE 2000 platform stops providing power to the External Optical Bypass module, or in case the power cable is disconnected from the optical bypass module, the External Optical Bypass module becomes active, bypassing the two GBE links to the SCE 2000 platform, and thus preserving network connectivity.

The figure below illustrates the operation of the bypass module when it is inactive (not in bypass). The data traffic is simply transferred through the bypass module to the SCE 2000 platform.

SCE 2000 4xGBE specifications

The Cisco Systems SCE 2000 4xGBE is a robust solution designed to optimize IP networks and enhance service delivery. As a member of Cisco's Service Control Engine (SCE) product line, this device is particularly suited for service providers looking to manage network traffic, improve service quality, and provide a suite of advanced management features.

One of the standout features of the SCE 2000 is its ability to process and analyze network traffic in real-time. This capability allows operators to gain insights into user behavior, application usage, and overall network performance. By utilizing deep packet inspection technology, the SCE 2000 can identify different types of traffic, enabling network managers to enforce policies and prioritize critical applications effectively.

In terms of interface capabilities, the SCE 2000 offers four 1 Gigabit Ethernet (GbE) ports. This versatility allows for easy integration into existing network infrastructure while ensuring ample bandwidth for data transfer. The device supports both IPv4 and IPv6 protocols, making it future-proof and suitable for evolving network demands.

One of the significant technologies employed by the SCE 2000 is Service Level Agreement (SLA) management. This feature ensures that service providers can meet their commitments to customers by monitoring performance metrics such as latency, jitter, and packet loss. The ability to generate reports based on SLA compliance allows for better customer engagement and transparency.

Additionally, the SCE 2000 facilitates dynamic resource allocation, enabling service providers to adapt network resources based on current demand. This elasticity is crucial in managing peak loads and ensuring a seamless user experience. Furthermore, the device’s support for Quality of Service (QoS) policies ensures that critical applications receive the necessary bandwidth and resources dedicated to maintaining operational efficiency.

The SCE 2000 also emphasizes security with features such as intrusion detection and prevention capabilities, helping protect the integrity of the network. This combination of performance monitoring, traffic management, and security makes the SCE 2000 an invaluable tool for service providers.

In conclusion, the Cisco Systems SCE 2000 4xGBE is a powerful network management solution that excels in providing real-time traffic management, SLA compliance, and security features. Its capabilities make it an essential component for service providers aiming to optimize their networks while delivering high-quality services to their customers.
