There is also a ++ Read and write at the same time, you can read and write at the same time, while writing at the same time, while reading and writing at the same time, without flush, can be measured using seek and tell.

GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently developed by beacon network, were officially introduced to the market, this is an important step in improving the Ethernet switch Product Lin

low address, where the sp pointer executes the last stack address used Here we introduce the second pointer bp, which is used to represent local variables in the range of this function (this ghost bp is used to indicate the starting address of these local variables. Note that, the starting address does not include sfp and ret) Bp and sp are based on the following operating mechanisms: 1. The called function first defines the original bp push as

media uplink Port has a two-port Ethernet port and a small pluggable (SFP) Gigabit Ethernet port, one of which is activated when used, but cannot be used at the same time. Network control and bandwidth optimization are achieved through advanced QoS, precise rate limiting, ACL, and multicast services. Network security through multiple authentication methods, data encryption technology, and network access control based on user, port and MAC address sim

When the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect vswitches: Stack and cascade. 1. GBIC and SFP 1) GBIC Cisco GBICGigaStack Gigabit Interface Converter) is a common and low-cost Gigabit Ethernet stack module that pro
