Key Considerations for Switch Selection and Main Technical Requirements for Ordering
1) Select reliable technical specifications: switching speed, switching capacity (Gbps), backplane bandwidth (Gbps), processing capacity (Mpps), and throughput (Mpps).
2) Design a proper test plan. Sufficient test ports are essential for accurately evaluating the switch's real-world performance.
3) Choose the correct product module configuration. Adopt a distributed switching processing architecture, ensuring all interface modules have local autonomous switching capabilities, thus avoiding the central switching bottleneck problem inherent in centralized switching structures.
4) Latency and jitter: Select industry-leading switches with latency less than 10 microseconds.
5) Multicast support: Commonly used multicast protocols include PIM and DVMRP. The product should support both multicast protocols simultaneously.
6) Rich interface types: Select backbone switches that simultaneously support Gigabit Ethernet, POS, and ATM broadband interfaces.
7) Stable routing protocol software implementation: Ensure the switch can implement the required routing protocols (such as BGP and OSPF).
8) Supports MPLS. A backbone network built using MPLS can support various applications such as traffic engineering and VPN.
9) The main technical requirements for ordering switches are high network data transmission capacity, strong data exchange capability, stability, reliability, and uninterrupted operation. Product selection should prioritize high performance, manageability, high reliability, applicability, and price-performance ratio.
10) The switch specifications and dimensions selected for the main server room must be able to be installed in the server rack.
Main specifications and parameters of switches include 8, 16, and 24-port RJ45 ports, rack-mount 19-inch auto-sensing Ethernet switches, supporting network standards 802.3 10BaseT and 802.3u 100BaseTX, backplane bandwidth: 4.8G, packet forwarding rate: 10M: 14,880pps; 100M: 148,800pps, 10M/100Mbps MAC address table: 4K. Additionally, intelligent and fiber optic switches are also available; selection should be based on network requirements.
