avaya routers and switches

Recently saw a lot of people asking about the switch, hub, router is what, function, what is the difference, the author on these questions to do some simple answers. First of all said Hub, that is, hubs. Its role can be simply understood to connect some machines to form a local area network. A switch (also known as a switched hub) works roughly the same as a hub. But there is a difference in performance: the way the hub uses shared bandwidth works, and the switch is the exclusive bandwidth. In

this is a very new technology. Some people also say that it is a three-layer exchange technology, there is no new things in the stack of routers and L2 switches. Is that true? Next, let's take a look at the working process of a layer-3 Switch through a simple network. Easy networkingDevice A with IP address ---------------------- layer-3 Switch ---------------------- Device B with IP AddressFor example, if

, the Spanning Tree Algorithm must be enabled to block the ports that generate the loop. The router routing protocol does not solve this problem. There are multiple channels between routers to balance the load and improve reliability. 2. Load aggregation: only one channel is available between switches, so that information is concentrated on one communication link and cannot be dynamically allocated to balan

Hubs, switches, and routers, which are known as network hardware, have always been active in the network field. However, many cainiao who are new to the network are annoyed by the fact that, they are not only similar in appearance, but also often stay together. It is a bit difficult to tell who they are! Let's take a look at the differences and relationships between them! 1. Hub 1. What is a hub? Before you

Until I read this post: http://jingyan.baidu.com/article/92255446ebe845851748f445.html ----- With the development of society, many families have 2 or several computers, in order to achieve the common computer network, routers and switches are slowly more people know, but because home routers and switches from the outs

of the telecommunications installation is not enabled routing function, enable DHCP. Turn on the ADSL routing function), if the personal Internet or a few units via ADSL itself can be, if the computer is more than you only need to purchase one or more hubs or switches. Consider the fact that the price difference between hubs and switches today is very small, not a special reason, buy a switch. No need to p

is another type of information transmitted between routers. It can send the link status and incoming notifications of information senders to other routers. 3. layer-3 Switching Technology A device with layer-3 switching is a layer-2 switch with layer-3 routing, but it is an organic combination of the two, it is not simply to overlay the hardware and software of the router device on the LAN switch. From the

Layer-3 switches and routers are widely used in various fields, including hub hubs. The most fundamental difference between a layer-3 Switch and a router is that a layer-3 Switch also has a "routing" function, which is consistent with the routing function of a traditional router. However, layer-3 switches and routers a

connected to the vro are allocated to different broadcast domains, and the broadcast data does not pass through the vro. Although vswitches above Layer 3 Have VLAN functions and can also be divided into broadcast domains, communication between subbroadcast domains is not allowed, and communication between them still requires routers. 4) vro function comparison: vro provides firewall services. A vro only forwards data packets of a specific address. It

Layer-3 switches are commonly used. Here we mainly analyze the differences between layer-3 switches and routers. Here we will share with you, hoping to help you. In recent years, with the rapid development of Internet/Intranet and the wide application of the B/S computing model, the cross-region and cross-network business has experienced a sharp increase. The ind

Internet cafe access Optical Fiber provides a faster and more stable network environment for Internet cafes. To achieve the best performance and functions of the entire network, a perfect combination of various optical fiber network devices is also required. Fiber optic network devices in Internet cafes are routers and switches. Router Selection: when the internet cafe adopts the fiber-optic access method
