A cold sore itself can cause swollen lymph nodes.
These two structures are the lymph nodes and the spleen.
It is connected by a network cable, switch and a router.

Swollen lymph nodes would be a symptom of a disease rather than the disease itself.
Cable is split into "nodes", which encompasses several residential units. Cable also has a limited amount of bandwidth. If the sum of all offered bandwidth for all subscribers on a node exceeds the amount of bandwidth actually available for the node, it is definitely possible to have periodic decreases in connection speed during peak usage.
A bus topology needs a trunk cable, which is a high speed central cable to which all the nodes can be connected. If the trunk cable breaks down, however, the whole network comes to a halt.
