Data Tunneling

Ping crossings is a reliable tunneling-effect TCP connection tool that connects to remote hosts via ICMP echo request and answer packets, commonly known as ping requests and replies. It is useful to circumvent firewalls, for whatever reason, to prevent outgoing TCP connections, but to allow incoming and outgoing ICMP packets. Tunneling is run by TCP access on the local computer that is able to run a proxy client from one machine inside the firewall. Ping crossings version Fixes a verified bug. This version is further repaired ...

The Ip_security Protocol (IPSEC) is a protocol recommended by the Internet Engineering Task Force (IETF) for IP security. VPN can be realized by the corresponding tunneling technology. There are two modes of IPSec: Tunnel mode and transport mode.    &http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; The IPSec protocol group also includes support for the network layer ...

In an internal email to Alibaba employees, Mr Ma said the IT era, with its control as the starting point, was moving toward the data age of Marvell, the purpose of activating productivity. With the development of computer technology, large data computing becomes more and more realistic, and companies based on large data application services are emerging. 　　The application of large data in the field of marketing has turned advertising into a "narrow"-precision marketing, and in the context of Internet finance, large data in the financial industry, the application of credit is gradually rising. Everyone is "data animal" different from ...

The challenge of large data has been widely concerned by the industry, and the so-called "http://www.aliyun.com/zixun/aggregation/14294.html" > Large data products have been springing up, At the same time on the big data of the confusion and controversy, which also makes users feel at a loss. A few days ago, EMC Senior product manager Li Junpeng, a large data and storage expert from EMC, was visiting the IT specialist's "guest room" to answer some misconceptions and doubts about big data ...

Data for the corporate network dark attack and defense war. Data caching, also known as data extrusion, refers to the transfer of data from a computer without authorization. For the corporate network, these types of attacks can be done manually, such as using a USB drive; in addition, this attack can also be automated, when the need to use the network to transfer data. In this article, we will highlight the web-based data caching techniques used during penetration testing, along with the corresponding security hardening measures. As tunneling technology, we assume that we do not have valid domain credentials. This means that I ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; The concept of clustering is easily confused with concepts (SMP, NUMA, MPP, distributed processing), whose primary difference is in the level at which resources are shared and replicated. 　　They are arranged by SMP, NUMA, MPP, clustering, and distributed processing from the most compact to the most loosely aligned. Because of the current network of the core parts with ...

IP Virtual Private network is a very complex technology, involving all aspects, the most critical of which is the tunnel technology. Simply put, the virtual private network is actually the data encapsulation of the enterprise network in the tunnel for transmission. Because the tunneling protocol is relatively complex, the virtual private network technology is complicated. The most typical of tunneling protocols are IPSec, L2TP, GRE, PPTP, L2F, and so on. Where GRE, IPSec belongs to the third-tier tunneling protocol, L2TP, PPTP and L2F belong to the second-tier tunneling protocol. The essential difference between the second and third-tier tunnels is that ...

The data center typically deploys the following three interconnected links, each of which is hosted with different data and functionality, as shown in the following illustration: three-layer interconnect. Also known as Data Center front-end network interconnection, the so-called "front-end network" refers to the data center for the Enterprise Park network or Enterprise WAN export. The front-end networks of different data centers (main center, Disaster preparedness Center) are interconnected through IP technology, and the campus or branch clients access each data center through the front-end network. When a disaster occurs in the primary datacenter, the front-end network will converge quickly and the client can secure business continuity by accessing the disaster preparedness Center ...

January 20 News, a few days ago, the foundation cloud service provider Qingyun Qingcloud announced the introduction of Load balancer (LB) of the private network mode and the router's IPSec Cryptographic tunneling service.       It is reported that the private network lb not only allows users to save the public network of IP, thereby saving it expenditure, but also through the private network lb to build more complex network architecture, so that enterprises with the physical world the same IT environment. Load ...

"Editor's note" Network after years of development, has come to the "post-Cisco" era, software definition network, network virtualization and other nouns have come to everyone, this article focuses on the traditional network architecture and SDN network of similarities and differences, the development of network virtualization, you can see, SDN manufacturers are gearing up, because of " We usually overestimate the changes in the next two years, and underestimate the changes that will happen in the next decade ", the traditional enterprises need to actively face the future changes in the network operation, the author from the Network Transformation and technology transformation in two aspects of the network industry in-depth discussion of the ...
