Core to Edge Networking includes all the networking devices needed to provide the right kind of connectivity to support end users whether they are on a Wired Switch or a Wireless Access Point. These devices include Switches, Access Points, Routers, and Firewalls. The network needs to support redundancy, Availability, Power over Ethernet (POE), Gigabit, Multi-Gigabit speeds, Network Access Control, Segmentation, among others.
When building the Core, redundancy is important. Making sure the core switches are setup in a way so there are multiple load sharing links from the edge switches and designing the core so when one fails all routing will still function. Some ways to accomplish this are by using a technology like Virtual Stacking, VSS, VPc, VSF, VSX, etc. where a second Core switch can take over if one fails.
Edge switches should have redundancy as well, typically they will be setup using Backplane Stacking or Virtual stacking with redundant links to the Core or Distribution Switches. Edge switches are being used for more and more different types of devices other than PC’s, Printers, and AP’s, they are also being used for lights, door locks, surveillance cameras and many other IoT functions. Keeping this in mind the network will be required to have more redundancy built into them.
WHY YOU NEED CORE TO EDGE?
Voice, Video, Surveillance
The network is the backbone of your business and needs to be available 100% of the time. The network needs to be secure, using Segmentation and NAC. New Access Points use 2.5Gbps interfaces requiring the Access Switches to be upgraded. More POE enabled devices like Lighting, Door locks, Video Surveliance cameras, IP Phones, PC’s are becoming more common.
Redundancy and higher speeds are needed between switches, router, and firewalls.
BENEFITS OF CORE TO EDGE
Allows for new applications like Lighting, Door Locks, and ever increasing IoT devices we have not heard of yet.
Newer Wi-Fi 6 Access Points can support more than 1 Gigabit of throughput so Multi-Gigabit 2.5Gbps and 5Gbps speeds are needed.
POE to support newer devices. Up to 90Watts of POE can be made available to power lights, PC’s, and more to come.
Hitless Upgrades, being able to upgrade switches with no downtime in the Core.
Better Security with 802.1X, User Based Tunneling, Software Designed Access, and Shortest Path Bridging technologies.
