rfc2544

RFC2544 RFC2544 RFC2544 provides a benchmark for network device testing. It defines a series of testing processes and methods so that service providers and users can use the same benchmark, reach consensus on the implementation and results of the test. RFC2544 standard frame length: 64 byte, 128 byte, 256 byte, 512 byt

The performance indicators of network products are mainly proposed in rfc2544 and rfc3511.It mainly includes throughput, latency, back-to-back, packet loss rate, new link per second, transaction processing per second, valid throughput (HTTP throughput), and maximum concurrency. Throughput, latency, back-to-back, and packet loss rate are defined in rfc2544 and belong to 2-3 tests. The UDP data type is used i

The main network elements in the Ethernet network include switches, routers, firewalls, servers, and clients. By testing the Ethernet network elements and the network itself, the network structure can be optimized, the network fault is eliminated and the network performance is mastered. Ethernet testing is also rule-based, such as the well-known rfc2544/rfc1242, rfc2889/rfc2285, RFC2647, the domestic yd/t1099-2001 (Gigabit Ethernet Switch Equipment te

CheckPoint i-security SP-5500 integrates the check Point Smartcenter Centralized m

some of the latest features with high value-added. Generally speaking, evaluating the advantages and disadvantages of a Gigabit Ethernet switch should begin with the overall architecture, performance, and functions. The overall architecture refers to the value of basic performance parameters, such as the port density, the maximum rate supported by the port, and the switching capacity of the switch device. This allows you to determine the location and grade of the device. In addition to the basi

When purchasing a vswitch. In terms of performance, in addition to meeting the basic standards recommended by RFC2544, namely throughput, latency, and packet loss rate, as user services increase and applications increase, all packets in the same range are mapped by the server switch and transmitted between the user and the same server. In general, asymmetric switches are mainly used in three environments: The network used in server/client mode, the co

basic performance parameters such as the port density, the maximum rate supported by the port, and the switching capacity of a layer-3 Switch. This allows you to determine the location and grade of the device. In addition to the basic RFC2544 standard, throughput, latency, and packet loss rate, the performance of a vswitch also increases with the increase of user services and application development, such as the number of MAC addresses, route table c

10G Ethernet switch, marking that the 10g performance of BigHammer6808 has entered the leading international ranks. Test Method In this test, we use the Adtech AX/4000 Broadband Network Testing Platform of Spirent Communications and two UNI-PHY testing modules and related testing software Router Performance Tester 4.43. We have tested the forwarding performance of the inter-board layer-7 Ethernet switch, and used BigHammer6808 two interface modules. The model is BH-2x10GE. Each module has a por

port density, the maximum rate supported by the port, and the switching capacity of the switch device. This allows you to determine the location and grade of the device. In addition to the basic RFC2544 standard, throughput, latency, and packet loss rate, the performance of a vswitch also increases with the increase of user services and application development, such as the number of MAC addresses, route table capacity (layer-3 Switch), number of ACLs

Huawei and Cisco occupy most of the market share of the networking equipment. As one of the mainstream devices in the market, GE switches are definitely a battle for the future. Next we will analyze the parameter standards of various indicators of Huawei Ge switches. As the core connection device of the enterprise network, the Huawei Gigabit Switch is the main standard to ensure the speed of the enterprise network. To help readers better understand the overall performance of the Huawei Gigabit S

performance parameters, so that the user can grasp the positioning and grade of the equipment in general. At present, thousands of gigabit switches from the port are divided into two, one is hundred trillion + gigabit mouth, one is a pure gigabit mouth. The former is a transitional type of gigabit switch, suitable for upgrading from the hundred Gigabit Network to gigabit network applications, Representative products are speed Networks sp2404g series (24 100M + 2 1000M + 2 optical fiber expansio

The purpose of software testing is to detect defects in software as much as possible, and software defects can be defined as omission of software implementation (omission of user requirement implementation), error (inconsistent with user's requirement), superfluous (additional implementation). 80% of errors are concentrated in 20% of the code----experience is justified ... 1. Test classification Black box testing, not focusing on internal implementation logic, regards all implementations as

Generally speaking, to judge the quality of the switch from the overall structure, function and function of three aspects. The overall structure refers to the port density of the switch equipment, the maximum speed of the port support and the value of the basic function parameters such as the AC capacity, so that the user can master the positioning and level of the device in general. The function of the switch, in addition to meeting the basic specification of

as a network device, performance is a must first consider the problem. If the firewall on the original network bandwidth impact is too large, is undoubtedly a huge waste of the original investment. At present, the firewall in the type of basically realized from the software to the hardware conversion, the algorithm also has a lot of optimization, the performance of some firewalls can be done to the original network performance impact is very small. specifically to the user, the performance of a

addition to the performance of the switch to meet the RFC2544 recommended basic standards, that is, throughput, delay, packet loss rate, with the increase in user business and application of in-depth, but also added some additional indicators, such as the number of MAC address, routing table capacity (three-tier switch), ACL number, LSP capacity, the number of support VPN. Take the number of MAC addresses as an example. The number of MAC addresses re

devices can be Anti-DDOS devices, IDS, IPS, and other devices. When the minimum SYN packet that only fills the IP header and TCP Header runs on the Ethernet, the maximum PPS supported is 100*10 ^ 6/(8*(64 + 8 + 12) = 148809 pps, 1488090 Mbit network, and the maximum PPS supported is pps. When vendors advertise their security devices, does their data comply with them? How is the maximum traffic supported by their IDS calculated? What content does it contain? Is the line rate advertised by their
