I. Small Business Network Program

Description:Small business networks usually have fewer information points and require simple management that is easy to implement for thereticulationWhen there is no special need, a simple tree or bus structure can be used.

Program I:

1, the basic network can be deployed at a single exit with a low-end router, using NAT technology as well as the use of default routes out of the office.

2. The aggregation side can use a mid-range Layer 3 switch to act as an aggregation, use inter-Vlan routing to forward data to the router to ensure fast data forwarding, enable DHCP service, and plan network segments as needed.

3, the access side of the use of network management of access switches, the use of basic Vlan division of the function, as required to each department to divide the area, easy to isolate and segregation.

Program II:

1, the basic network can be a single exit to deploy a low-end router, the use of NAT technology as well as the use of the default route out of the office, the use of single-arm routing technology to forward Layer 3 data, enable DHCP services, on-demand planning network segments. (Single-arm technology can be ignored if there is a single LAN)

2. Use a switch with slightly higher forwarding performance on the aggregation side, and divide the vlan on the aggregation switch (if there are fewer information points, there can be no aggregation layer).

3, the access side can use foolproof switch, easy access to information points, exempt from configuration.

Advantages of Small Network SolutionsEasy to manage, easy to work with and troubleshoot, low hardware and equipment costs.

II. Network solutions for medium-sized enterprises

Description: medium-sized enterprise network information point moderate, for network quality has a certain demand, so you can consider a certain network redundancy; for medium-sized and large enterprises will have more internal and external network servers, the security of servers also need to be guaranteed; these enterprises will generally have a dual-line situation, you need to consider the utilization of the export bandwidth and so on;

Programs:

1、Access layer is recommended to use managed Fast Ethernet switches (if the budget permits, you can use the front-gigabit switches), divide the corresponding Vlan according to the pre-planned IP segments, and enable a variety of access tests such as port detection and secure port characteristics on the access switch, which can effectively prevent private terminals or malfunction caused by misuse of the problems generated by the faults.

2. High-performance multi-layer switches are used in the aggregation layer, and the Layer 3 switches are connected to therouter (computing)Adopt full interconnection connection, use port aggregation function between switches to improve link bandwidth and availability; Aggregation switches open gateway redundancy technology, mutual backup gateway to improve network redundancy; Enable multiple spanning tree protocols, rational planning of the network; Enable Layer 3 switching function, fast forwarding of data. Simple routing protocols can be set up with upper layer routers to flexibly control the routing direction (e.g. RIP), and static routing can also be used;

3. The core side is forwarded with high-performance routing, front-endfirewallsAs the Internet border (or directly use the firewall to act as an outlet), there are multiple lines can be used as a border gateway with load function, so that the traffic bandwidth can be reasonably utilized (such as the use of FCS AD, F5 load-balancing equipment, etc.), and for the development of servers in the extranet, they can be placed in the DMZ area of the firewall, so as to realize the protection and control (or mapping of available ports on the firewall, and placing the servers in the intranet). (or map available ports on the firewall and place the server in the intranet).

4、If there are branch companies or mobile users access needs, on-demand use of VPN interconnection, or SSLvpn and other access to the business system (can choose a common IPsec VPN access program)

Medium Enterprise Network Solution AdvantagesRedundant network, reliability and high availability are guaranteed, network performance is fully utilized, management is relatively easy and network expansion is highly flexible.

III. Large enterprise network program

Description:

Network independence requirements: Most large enterprises have separate office and production networks, and there are requirements for isolation as well as openness for the connection between each network.

Access Requirements for Enterprise Information Points: Individual branch access, access to information points.

Bandwidth performance requirements: Multi-service for bandwidth and latency have certain requirements, must be done to the core of the 10 Gigabit level, Gigabit to the desktop in order to meet the needs of the scale and business growth.

Stability requirements: With large-scale network applications, corresponding reliability design is needed to ensure smooth network and normal operation of the system.

network securitydemand for: Modern large-scale enterprise networks facing the Internet must have a perfect network security solutions to protect against attacks and reduce economic losses.

The core equipment, aggregation equipment, servers and backbone links are all designed with redundancy to ensure the continuity of key nodes. The exit adopts multi-exit design, each area access uses standard VPN access, dynamic routing is used to establish connections between branches, reasonable Vlan is divided in the large convergence area to isolate broadcast storms and ensure network performance, and gateway redundancy technology is used at the convergence level.

Network security aspectsFirst of all, the network exit security, headquarters and branch exits on-demand deployment of a new generation of firewalls (redundancy can be taken to design), on-demand can also set up some anti-spam and other equipment deployed to the network. Second is the intranet access security, in the access switch to enable some port security features such as DHCP snooping, anti-ARP spoofing of the basic functions, the deployment of antivirus software server in the intranet, the client to the desktop, security protection to the terminal. There is also the enterprise authentication, access, not described here.

Wireless: The access layer can use wired wireless integrated switches to connect the regional APs for unified control.

Huawei's Smart & Simple All-Optical Network strategy brings the ultimate business experience to every person, family, and organization by creating an intelligent, extremely simple, ultra-wide, and ubiquitous next-generation all-optical network. Based on this strategy, for the three major scenarios of all-optical transmission, all-optical data centers, and all-optical parks, Huawei gathers three series of products, namely, optical transmission, optical access, and optical terminals, to carry out continuous innovation in order to lead the development of the global optical industry.

With applications in ISPs, energy, transportation, finance, education, healthcare, manufacturing, and other industries across the board, it helps fiber optics create ubiquitous optical connectivity from home to room, from plant to machine, and from office to desktop.

Data Center Optical Network Connectivity

According to GlobalData's analysis of market size and market forecasts, the global cloud ecosystem continues to grow at a compound annual growth rate (CAGR) of 25.3% and is expected to reach $720 billion by 2022.

Internet giants, ICPs and enterprises use DCI (Data Center Interconnect) solutions to provide high-quality, near-unlimited bandwidth connectivity to their data centers, while controlling costs by building their own infrastructure. However, with the massive growth in the scale of data center construction, the demand for data center interconnect has multiplied, and one of the challenges of data center interconnect is how to make the best use of the limited fiber optic resources and obtain reliable high-capacity transmission.

In addition, because the service issuance and maintenance mode of optical analog signals are different from the ordinary digital network, the IT personnel in charge of the data center network usually do not have the foundation of optical transmission technology. With the proliferation of equipment brought about by the increasing volume of data, the rapid opening of services, fast and accurate troubleshooting has become a new challenge for the interconnection of data centers.

Therefore, when building a DCI solution, it is important to consider not only the need for connectivity bandwidth, but also the need for O&M simplicity, intelligence and security.
