lightweight library written in C, licensed under the lgpl, that provides a common wait action for several readiness notification schemes. it is significantly easier to use then sigio, and about as easy to use as kqueue, epoll, And the edge-triggered variant of sys_epoll.
New readiness notification schemes can easily be supported by writing a new "subclass" of RN.
It currently only supports edge-triggered readiness notification schemes. it cocould easily be used with level-triggered schemes
following aspects. 1. Pay attention to the full configuration of the same throughput as any electronic product, when you select a third tier switch, you first need to analyze the performance metrics for each product, but with many technical metrics such as switching capacity (Gbps), backplane bandwidth (Gbps), processing power (MPPs), throughput (MPPs), you'd better hold on to The "throughput at full configuration" metric, because other technical metrics users typically do not have the abilit
What needs to be clear is that all the products on the market that are known as NP firewalls are not really NP firewalls, such as high-end X86 CPU architecture, multi-core CPU architecture firewall, in fact not a real NP firewall. The user must carefully carry on the actual test to the equipment. The test can be based on universal network test equipment such as smartbits or Ixia. Testing and the use of the actual environment, is to identify true and f
generation. In the lab, it is difficult for a route to generate a loop. Therefore, in the test, the detection loop is usually achieved by setting a small number of LDP hops. The LDP Neighbor Relationship Between the router configured with the loop check and the router not configured with the loop check is established, ldp map message processing that does not carry the loop check, and MAP message processing that does not have the loop check attribute. Processing LDP messages that are about to re

device:Many existing testing and monitoring products do not fully process higher data rates. There are some products on the market that generate load and monitoring performance for 40/100 GbE environments, such as products from test equipment vendors Spirent Communications and Ixia.
After Upgrade:What is network performance testing required?
End-to-End throughput test:This test emphasizes the main reason for the upgrade: a large amount of data needs
in the transmission of triple playback services:
◆ A large amount of downstream bandwidth is wasted: the EPON system uses a broadcast transfer method in the downstream mode: Each ONU will receive a large amount of traffic sent to other ONU, wasting a lot of downstream bandwidth.
◆ Large uplink latency: when sending data to the OLT, The ONU must wait for the transfer opportunity allocated by the OLT. Therefore, the ONU must cache a large amount of upstream traffic, this results in latency, jitte
a layer-3 test. Take the outstanding layer-3 Switch DGS3308TG of Digital China D-Link as an example. We connect the eight Gigabit ports of the vswitch with the eight Gigabit ports on the IXIA1600 tester. We configure the layer-3 Switch DGS3308TG, set the eight ports to eight different VLANs, and then set IP addresses for each VLAN. Then we configure the eight ports of IXIA, set their IP addresses to the IP subnet of the connected port, and then start
analyze the performance indicators of various products. However, for example, switching capacity Gbps) and Board bandwidth Gbps), processing capability Mpps), throughput Mpps) and many other technical indicators, you 'd better grasp the "throughput when the configuration is full", because other technical indicators users are generally unable to measure, only throughput is an indicator that users can use Smart Bits and IXIA testing instruments for dir
Ixchariot IntroductionIxia's application layer performance testing software Ixchariot is a unique testing tool and is an industry-proven test system for application-level performance testing. Ixchariot can evaluate the performance and capacity of network applications, stress test the network and equipment, and get the performance parameters such as throughput, delay, packet loss, reaction time and so on for different applications and different parameters of the equipment and network. As a test

It is reported that Huawei, ZTE, China Three communications, Cisco, intel , freescale , , Ruijie, ixia , think Bollen, netronome , windriver and other top dozens of global manufacturers will appear on the scene of the conference, sdn , NFV and other future network technology development status and enterprise strategic deployment presenta
layer-2 switching, and the price is relatively low. Since there are many features and the price is low, it should be favored by enterprise users. How should we select switches? How to select a vswitch: (1) Selecting trusted technical indicators: Like any electronic product, when selecting a layer-3 switch, we should first analyze the performance indicators of various products. However, for example, switching capacity Gbps) and Board bandwidth Gbps), processing capability Mpps), throughput Mpps)
