Chapter 6 Cabling the Line Ports and Completing the Installation

Connecting the line ports to the network

Single Link: Receive-only Topology

In this topology, an optical splitter resides physically on the GBE link that the SCE 2000 should monitor. The optical splitter is connected to the SCE 2000 via Rx links only.

In this topology, the traffic passes through the optical splitter, which splits traffic to the SCE 2000.

Note Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.

Figure 6-2: Cabling Diagram for Single SCE 2000 Single Link Receive-only Topology

The single link receive-only topology cabling is similar to that for single link inline, in that either the first GBE link (first two ports) or the second GBE link (third and fourth ports) can be used, as illustrated in the diagram above. The remaining pair of ports is unused.

Either port 1 or port 3 is used for connecting to the network element that is deployed on the subscriber side of the SCE 2000 while port 2 or port 4 is used for connecting to the network element that is deployed on the network side of the SCE 2000.

Dual Link: Single SCE 2000 Topologies

In this topology, one SCE 2000 is connected to two full duplex, GBE links. The SCE 2000 may be either inline, to support both monitoring and traffic control functionality, or receive-only for traffic monitoring functionality only.

When one SCE 2000 supports two links, the first two ports are connected to one link, while ports 3 and 4 are connected to the second link as follows;

Port 1: Link 1, Subscriber side

Port 2: Link 1, Network side

Port 3: Link 2, Subscriber side

Port 4: Link 2, Network side

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.
