The current communication methods are inseparable from the IP network. To combine the two, you must use the gateway. Now let's talk about the knowledge of Cisco's unified voice gateway. Which models are available in these products, and what are the differences between these models? Cisco Unified Communication Voice Gateway Cisco 1700, 2600XM, 2800, 3700 and 3800,

Session 1 ARP Proxy technology1. ARP ProxyThe ARP proxy feature is the L3 layer gateway device for all functions, routers or L3 layer switches. The ARP proxy function uses the ARP protocol's unreliability to replace the terminal to carry on the L3 layer forwarding, because Arp-requst broadcast is L3 layer isolation, therefore needs L3 layer gateway to replace the terminal to carry on the Arp-requst, when th

The principle of CSG for setting an instance on a mercury router is described in two ways: the gateway concept and the setting of a wireless router. It is easy to complete the setting. Hurry into the Wireless World. As we all know, walking from one room to another must go through one door. Similarly, sending information from one network to another must go through a "Gateway", which is the

1. What is a WAP Gateway? A WAP Gateway is a software. It connects to the Internet or Intranet, so that WAP phones can access resources in it. Some gateways may be able to convert HTML files to WML pages.The WAP Gateway provides many functions in the connection between the WAP device and the web server. These functions are basically: Convert the markup langu

10. Conclusion The BGP protocol provides high control and flexibility for Inter-Domain Routing, implements policy constraints, and avoids routing loops. The guidelines described here provide a starting point for BGP use. As BGP grows, it will provide more advanced and manageable routing methods. 　　 Appendix A. Relationship between BGP and IGP 　　 This section describes how to exchange routing information between BGP and IGP. These methods are not proposed as part of standard BGP. These methods ar

Configure Oracle Gateway 12 to connect to SQL Server 2014 In recent work, we need to connect to SQL Server 2014 based on Oracle. We can configure Gateway to implement this function. This Gateway is actually implemented through dblink. That is, the SQL Server is simulated into a remote Oracle instance, which is received and forwarded by the

To get a thorough understanding of BGP, we'll start by answering the seemingly simple question of why BGP is needed, that is, how BGP is generated, and what it solves. With these questions, we will briefly review the trajectory of a routing protocol development.The essence of the first route is to describe the expression of a network structure, and the routing table is actually a collection of results. In the early Arpanet network era, the network size is limited, the number of routes is not sma

two digits can be arbitrarily varied within the 0~255 range, providing 2,552 IP addresses. However, the actual number of IP addresses available is 2552-2, or 65,023.The subnet mask setting for the IP address is not arbitrary. If the subnet mask is set too large, that is, the subnet range is enlarged, then, according to the subnet path rule, it is likely to be sent to the local machine is not in the same subnet of the destination machine data, because of the wrong judgment and think that the des
