Basic IO Graphs:IO graphs is a very useful tool. The basic Wireshark IO graph shows the overall traffic situation in the capture file, usually in units per second (number of messages or bytes). The default x-axis time interval is 1 seconds, and the y-axis is the number of messages per time interval. If you want to see the number of bits per second or byte, click "Unit" and select what you want to see in the
Wireshark non-standard analysis port no flow2.2.2 Non-standard analysis port non-flow wireshark non-standard analysis port trafficApplication execution using non-standard port numbers is always the most concern of network analyst experts. Focus on whether the application intentionally involves using a nonstandard port, or secretly wants to try it out through a fi
a simple concept of the main record stream network and the maximum flow ( The implementation algorithm of the maximum flow may be supplemented later ) , the main explanation is to use the Hungarian algorithm to find the maximum matching of the binary graph. 1 : Streaming Network Stream network is g (V, E) is a finite grap
from all over the world who specialize in one type of aircraft, each of which has two drivers and requires a pilot and a co-pilot. For a variety of reasons, such as co-ordination, some pilots cannot fly on the same plane and ask how to match the driver to make the most of the flight., assuming that there are 10 drivers, the V1,V2,...,V10 represents up to 10 drivers, of which V1,V2,V3,V4,V5 is the pilot, and V6,V7,V8,V9,V10 is the co-pilot. If a pilot and a co-pilot can fly on the same plane, on

Repeat this process until you cannot find any augmented paths * This algorithm uses the EDMONDS-KARP algorithm (an implementatio

Data Flow Diagram (DFD)A Data Flow Diagram (DFD) is a tool used in the SA method to represent the system logic model. It graphically depicts the process of data flow and processing in the system, because it only reflects the logical functions req
The main problem: There are n planets, your task is to use the shortest time to the K supercomputer from Planet S to the planet T. Each supercomputer needs a spaceship to transport it, there are m two-way tunnels between the planets, each tunnel takes a day to pass, and no two ships can use the same tunnel at the same time, and the tunnel does not connect two identical planets, and there is at most one tunnel between each pair of planets.The idea of solving problems: according to Great White boo
obvious that this graph has an Euler loop. The problem now becomes: Which side should be changed to allow each point to exit =? Construct a network flow model. The directed edge cannot be changed. Delete it directly. The directed undirected edge is set to what direction, and the network is constructed. The maximum side length is 1. Create another S and T. For the inbound> outbound vertex u, the connection
The first big question in the soft exam is the design of the data flow diagram. This question is a test of the patience, care, and confidence of the reference person.
Concept:
In my personal understanding, the data flow graph is a list of operations (processing) involved by each role (entity) in a system, the documents and materials used and generated during the

's written in front .
Network flow with upper and lower bounds is limited by the flow of the edge, which must be within the range of [Down,up].
In fact, the ordinary network flow is a special network with the upper and lower bounds of the flow

Then you can also optimize the direction of the search, BFS can run from T to S, DFS can run from S to
the number of paths = number of points at the end of the path = total number of points-number of non-end points = Total number of points-two of the number of matches in the graph, so let's do a binary match.As the ball number increases, the minimum number of columns required is monotonous, so it can be two points. But two points each time to re-build the maximum flow, if enumerated in sequence, each time o
