Suppose the network layer provides the following service.
(i)-the network layer in the source host accepts a segment of maximum size 1,200 bytes and a destination host address from the transport layer.
(ii)-the network layer then guarantees to deliver the segment to the transport layer at the destination host.
suppose many network application processes can be running at the destination host.
a. design the simplest possible transport-layer protocol that will get application data to the desired process at the destination host. assume the operating system in the destination host has assigned a
4-byte port number to each running application process.
b. modify this protocol so that it provides a "return address" to the destination process.
c. in your protocols, does the transport layer "have to do anything" in the core of the computer network?

Consider the following statements: #include #include class temporary { private: string description; double first; double second; public: temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string& , double& , double& ); void setdescription(string); void setfirst(double); void setsecond(double); }; write the definition of the member function set() so that the instance variables are set according to the parameters. write the definition of the constructor so that it initializes the instance variables using the function set() write the definition of the member function manipulate() that returns a decimal number (double) as follows: if the value of description is "rectangle", it returns first * second if the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. hint: the volume of a cylinder is simply the area of the circle at the base times the height. if the value of description is "sphere" it returns the volume of the sphere with radius first. otherwise it returns -1.0;
