There is a limit to the number of TCP connections and the throughput that a single webserver can acheive. Perhaps the greatest challenge of all is keeping the data center network diagram, or diagrams of the extended network, up to date with accurate information -- this could be a full-time job. Access switches are usually located at the top of the rack, so they are also known as ToR (Top of Rack) switches, which are physically connected to the server. Do Not Sell My Personal Info Traditionally, Cisco has recommended a multi-tier tree based data center topology as depicted in the diagram below. Only include relevant information. However, be careful to not be too excessive; a diagram that isn't used is a diagram that won't get updated. It shows the components that make up a network and how they interact, including routers, devices, hubs, firewalls, etc. Since the destination port is needed to “demultiplex” the UDP packet to the VXLAN endpoint this leaves the UDP source port as the only field that can be varied. You can use this easily customizable template to represent an existing data center network diagram. Data Center Networks (Cont) Core routers manage traffic between aggregation routers and in/out of data center All switches below each pair of aggregation switches form a single layer-2 domain Each Layer 2 domain typically limited to a few hundred servers to limit broadcast Most traffic is internal to the data center.
