A routing table is a data file in RAM that is used to store route information about directly connected and remote networks. Nodes can also share the contents of their routing table with other nodes. The primary function of a router is to forward a packet toward its destination network, which is the destination IP address of the packet.
IP routing is the application of routing methodologies to IP networks.This involves not only protocols and technologies but includes the policies of the worldwide organization and configuration of Internet infrastructure.
Administrative distance (AD) or route preference [1] is a number of arbitrary unit assigned to dynamic routes, static routes and directly-connected routes. The value is used in routers to rank routes from most preferred (low AD value) to least preferred (high AD value).
NOTE: a RID is the highest logical (loopback) IP address configured on a router, if no logical/loopback IP address is set then the router uses the highest IP address configured on its active interfaces (e.g. 192.168.0.1 would be higher than 10.1.1.2). Usually the router with the second-highest priority number becomes the BDR.
Routing calculates good paths through a network for information to take. For example, from node 1 to node 6 the best routes are likely to be 1-8-7-6, 1-8-10-6 or 1-9-10-6, as these are the shortest routes. Routing is the process of selecting network paths to carry network traffic. Routing is performed for many kinds of networks, including ...
A label with the value of 1 represents the router alert label. Traffic Class (TC): 3 bits Field for QoS (quality of service) priority and ECN (Explicit Congestion Notification). Prior to 2009 this field was called EXP. [12] Bottom of Stack (S): 1 bit If this flag is set, it signifies that the current label is the last in the stack.
More recently, this hierarchical technique was applied to wireless mesh networks using the Optimized Link State Routing Protocol (OLSR). Where a connection can have varying quality, the quality of a connection can be used to select better connections. This is used in some ad hoc routing protocols that use radio frequency transmission.

For example, if the DUT has 5 ports and a two port VNA is connected with VNA port 1 to DUT port 3 and VNA port 2 to DUT port 5, the measured VNA results (, , and ) would be equivalent to , , and respectively, assuming that DUT ports 1, 2 and 4 were terminated in adequate 50 Ohm loads . This would provide 4 of the necessary 25 S-parameters.
