Understanding the Cisco 3925 Throughput Datasheet
The Cisco 3925 Throughput Datasheet is a vital document that outlines the performance capabilities of the Cisco 3900 Series routers, specifically focusing on the 3925 model. It's not just a list of features; it's a deep dive into how much data the router can handle under various conditions. This information is essential for network engineers, IT managers, and anyone responsible for ensuring their network can meet current and future demands.
These datasheets are designed to provide clarity and precision. They typically detail throughput figures for different network services and configurations. Consider these key aspects:
- Maximum Throughput: The absolute highest data transfer rate the router can achieve.
- Throughput with Specific Services Enabled: Performance metrics when features like Quality of Service (QoS), encryption (IPsec), or firewalling are active. These services consume processing power and can impact overall throughput.
- Throughput per Module: If the router supports various network interface modules, the datasheet may break down performance based on the types of modules installed.
To illustrate how these figures are presented, imagine a simplified table within the datasheet:
| Configuration | Throughput (Mbps) |
|---|---|
| Baseline (No Services) | 150 |
| With IPsec Encryption | 75 |
| With Firewall Enabled | 100 |
This type of granular data allows for accurate planning. For instance, if your network requires 120 Mbps of encrypted traffic, you can immediately see that the Cisco 3925, under those conditions, is a suitable choice. Without this detailed information, you might underestimate the router's capabilities or, conversely, over-provision and waste resources. The datasheet also often includes information on factors that can influence throughput, such as:
- The specific IOS (Internetwork Operating System) version running on the router.
- The type and number of service modules installed.
- The nature of the traffic (e.g., small packets versus large packets).
- The duplex settings of connected interfaces.
