FacebookTwitterGoogle+LinkedInRedditTumblrShare

Choosing a data switch for your network can be a daunting task, given the myriads of vendors out there who are vying for providing network switches with fancy functions and feature sets. It may get more challenging when deciding which core switch and edge switch to buy: you have to make sure the switch you get is up to date so it can take advantage of latest technologies, and allows you to squeeze every last drop of performance out of the system. So, whether to choose a core switch or edge switch? Let’s go through their functions and roles within a network, and link these with you are gonna achieve, then you may find the answer.

What Is a Core Switch?

A core switch is a high-capacity switch generally positioned within the backbone or physical core of a network. Core switch is also regarded as a backbone device that is vital to the successful operation of a network: it serves as the gateway to a wide area network (WAN) or the Internet, so that you can use it to connect to servers, your Internet service provider (ISP) via a router, and to aggregate all switches. A core switch need to be powerful enough and have significant capacity to handle the load sent to it, which means it should always be a fast, full-featured managed switch.

In a public WAN, a core switch interconnects edge switches that are positioned on the edges of related networks. In a local area network (LAN), this switch interconnects work group switches, which are relatively low-capacity switches that are usually positioned in geographic clusters.

How About an Edge Switch?

As the name indicates, an edge switch is a switch located at the meeting point of two networks. These switches connect end-user local area networks (LANs) to Internet service provider (ISP) networks. Referred to as access nodes or service nodes, an edge switch connects client devices, like laptops, desktops, security cameras, and wireless access points to your network. Edge switches for WANs are multiservice units supporting a wide variety of communication technologies, it also provides enhanced services such as virtual private networking support, VoIP and quality of service (QoS). Generally, smart switches and even unmanaged switches are valid options at the edge of your network. But for some downtime-sensitive applications or where security matters, a managed switch can also be equally used at the edge.

Core Switch/Edge Switch Selection: What Exactly Matters?

To select the appropriate switch for a layer in a particular network, you need to make clear specifications regarding current/future needs, target traffic flows and user communities.

1. Future Growth

Switches comes in different sizes, features and function, choosing a switch to match a particular network involves a solid network plan for any future growth. With that in mind, you would want to purchase a switch that can accommodate more than 24 ports, such as stackable or modular switches that can scale.

2. Performance

When selecting a switch for the access, distribution, or core layer, consider the ability of the switch to support the port density, forwarding rates, and bandwidth aggregation requirements of your network.

An edge switch needs to support features such as port security, VLANs, Fast Ethernet/Gigabit Ethernet, PoE and link aggregation. While a core switch also needs to support link aggregation to ensure adequate bandwidth coming into the core from the distribution layer switches. Also, a core switch support additional hardware redundancy features like redundant power supplies, and hot-swappable cooling fans. So there is no downtime during switch maintenance.

How to Build a 10G Home Network?

The network has become the lifeblood for home and small business. It changes the way we live, work and communicate. Nobody today would deny the importance of the network, while it keeps evolving to satisfy the requirement of people. 10G home network, in this case, are no longer restricted to use in small and middle-sized business. It’s not uncommon for home to start with a 10G network setup. So how to get 10G home network? You may find some clues in this article.

Begin with Needs Assessment

Pretty much everything nowadays rely on a fast and reliable network, which leads to tremendous traffic and applications running on the networks and it keeps growing at high pace. Deploying 10G home network at home eliminates network congestion at busy times while improves your productivity.   Better planning before deployment to ensuring your network can handle your business needs. You should ask yourself a few questions, such as how many computers, printers and other peripherals will connect to your network? How much wireless coverage will you need at your location? What type of mobile devices will need access to your network?

What Makes a 10G Home Network?

10G Ethernet makes streaming and sharing files over local network much faster. And 10GBASE-T standard is going mainstream into the consumer segment thanks to its lower power consumption and compatibility with existing infrastructure.

10g home network

To build a 10G home network, several components are indispensable: 10G core switches, access switches with 10G uplinks, and 10G network interface cards for servers and storage devices. The past few years had witness the price dropping of 10G network switches. For example, the cost of Ubiquiti Unifi and Eageswitch switches are only $200. And FS 10G network switch like S3800-48T4S only cost $480 by offering 48 100/1000Base-T and 4 10GE SFP+. When it comes to access switches with 10G uplink, FS S3800 series switches offers 24 ports with 4 10G uplinks at very decent price. These switches are well suited for home network use.

What About 10G Cabling – 10GBASE-T, DAC or SFP+?

Upgrading the existing 1G network to 10G can be simple. As 10G switches also support 10GBASE-T, you can use the same RJ45 network cable to connect the 10G switch with your servers, storage and some other switches. The only difference is to use Cat6a network cable instead of Cat5e and Cat6 cable, or choose SFP+ 10GBASE-T modules with 2.5W power consumption and a maximum distance of 30 m.

For 10G switches that support 10G SFP+, you should use these ports if you have devices that come with 10G SFP+ port, or you need a 10G connection to other switches over 100m away. SFP+ ports look just the same as SFP ports on your Gigabit switches, but they’re now running at 10 Gigabit. For servers or storage devices with 10G SFP+ port, the most cost efficient way to connect is to use 10G DAC (direct attach twinax cable). These are basically copper cables with SFP+ connector on both sides, and they come in various lengths.

10g-dac-cable

To connect switches over 100 m apart, a pair of SFP+ modules and the matching fiber cable are needed between them. Depending on the length required in home network, you can use 10G optics such as 10GBASE SR SFP module and multimode fiber to reach 300 meters. FS offers a wide range of 10G SFP+ modules and fiber patch cables for short and long distance transmission.

Conclusion

This article presents you some basic facts about 10 Gigabit Ethernet and how you can build a home network over 10 Gigabit. FS provides comprehensive 10G solutions: all the components mentioned to build a 10G home network are available at FS.COM, including Cat6a Ethernet cables, fiber patch cables, DACs and 10G SFP+ modules.
