, we should also see the deficiencies of the POC, the most important is the call to establish delay performance and call delay performance is not high, this is mainly because the POC is based on the public mobile cellular network VoIP technology implementation. Therefore, POC can not be used in the case of emergency linkage and emergency call like digital trunking communication. At the same time, because of the low reliability and security of POC, POC

layer--networkThe network layer belongs to the higher level of OSI, from its name can be seen, it solves the network and network, that is, the communication between the Internet, rather than the same network segment inside the matter. The main function of the network layer is to provide routing, that is, to choose the best path to reach the target host and route the packets along that path. In addition, the network layer should be able to eliminate network congestion, with traffic control and c

the office network, so that VLAN2 and VALN3 become two security zones. Overall PlanTake the Cisco Catalyst 1900 switch and the Cisco 2600 router as examples to describe the detailed configuration of the solution.VLAN Planning(1) VLAN working mode: we use the static mode to specify the VLAN for the switch port.(2) ISL label: ISL (Inter-Switch Link) is a protocol for transmitting VLAN information and VLAN data streams between switches, between switches and routers, and between switches and server

switch will directly transfer the source address to the destination address from the layer-2 based on the address ing table generated and saved for the first time, instead of being processed by the layer-3 routing system, the network delay caused by route selection is eliminated, the data packet forwarding efficiency is improved, and the speed bottleneck caused by route information transmission between networks is solved. As mentioned above, a layer-3 Switch combines the advantages of a layer-2

set to two-way Asymmetric mode between upstream and downstream ), it can also bind a Trunking Connection Based on the Data MAC address to achieve Traffic Sharing and fault self-recovery. The V5924 VDSL switch of the Chashan network provides the IEEE 802.1 P Ethernet CoS function and supports QoS classification. On this basis, you can implement IGMP Video Multicast in a broadband network. In addition, V5924 also supports full-duplex traffic control ov

the switch port. Dynamic VLAN: by setting the VMPSVLAN Membership Policy Server), it contains a ing table between MAC addresses and VLAN numbers. When the data frame arrives at the switch, the vswitch queries VMPS to obtain the vlan id of the corresponding MAC address. 2) ISL label: ISLInter-Switch Link) is a protocol for transmitting VLAN information and VLAN data streams between switches, between switches and routers, and between switches and servers, by configuring ISL encapsulation on the p

STP initialization process is not needed. During the STP initialization phase, the port goes through five stages of STP: blocking, listening, learning, forwarding, and failure. The entire process takes 15 seconds. Therefore, if you are sure what you want to connect to, you can terminate this process. Test the Ethernet Channel Configuration The next step is to test the Ethernet channel, which is bound with the layer-3 Switch Port to provide more Ethernet connections. If one channel fails, the E

Switch-Huawei S3526 route switch is shown in Figure 1) QuidwayS3526 is a two-or three-tier line rate Routing Switch launched by Huawei for the network convergence layer of the broadband IP metropolitan area network. The network operating system provides a sound routing protocol, VLAN control, traffic switching, and QOS Assurance Mechanism, it provides complete business control and user management capabilities, and is an ideal product for IP Broadband Metropolitan Area Networks.

It is very simple and straightforward to configure three or more switches to support a virtual LAN and a network partition. However, ensuring that a virtual private network can withstand attacks is totally different! To ensure the security of a virtual LAN, You Need To Know What attacks you want to protect it against. The following are several common methods to attack a virtual LAN, how you fight against these attacks, and how to reduce attack losses in some situations. Virtual LAN jump attack T

product for IP Broadband Metropolitan Area Networks. Supports VLAN Trunking. Port Configuration: 24 10/100 BASE-TX ports and 2 GE expansion module slots. Five GE extension modules are supported. Due to cost considerations and sufficient bandwidth performance, this solution does not use the GE extension module, but uses the TRUNK technology to achieve MB uplink bandwidth. This scheme requires one purchase. Quidway S3050 Ethernet switch is a L2 line ra

Mbps. In this way, computers of different vswitches can only communicate with each other through the mbps bandwidth. The two switches are connected together through stacks, And the stacked cables can provide a bandwidth higher than 1g, greatly reducing the bottleneck. Now there is a new technology for vswitches-Port Trunking. With this technology, you can use multiple twisted pair wires to cascade two vswitches to increase the cascade bandwidth. Le

monitoring port can only be used in one SPAN at the same time. The monitoring port is not used in other layer-2 protocols, such: Cisco Discovery Protocol (CDP ), VLAN Trunk Protocol (VTP ), Dynamic Trunking Protocol (DTP ), Spanning Tree Protocol (STP ), Port Aggregation Protocol (PagP ), Link Aggregation Control Protocol (LACP. By default, the monitoring port does not forward any data streams other than the SPAN Session. You can also set the ingress

multiple MAC addresses, the port must be uplink) A vswitch or HUB. Two important functions of the vswitch MAC table: 1. The vswitch uses the MAC table to implement targeted data forwarding and improve efficiency. 2. in actual network applications, it is convenient for management personnel to troubleshoot the data forwarding process of network cables unicast: Check the MAC table with entries: targeted Forwarding (but when the source MAC and target MAC are the same port, discard-MAC filter) www.2

Linux Network Setting tips: Enable multi-nic bonding-Linux Enterprise Application-Linux server application information. For more information, see the following. ? You can use multiple NICs to create a network card with the same IP address. This technology actually exists in sun and cisco, respectively known as Trunking and etherchannel technology. In Linux, this technology is called bonding. ?? Because bonding is included in kernel 2.4.x, you only ne

As bandwidth increases and data traffic increases, data interfaces in the core part of the Network will

This is the trunking technology, which is not an independent device, it is a common technology used by switches and other network devices. Modern Server Load balancer technology usually operates on Layer 4 or Layer 7 of the network. This is a server Load balancer Technology for network app
