Abstract

A system to manage network resources of a network so that network performance is predictable and manageable is disclosed. According to the system, network resource utilization is monitored and then computer systems seeking to transmit or receive data over the network as requested to do so at times that serve to more efficiently utilize the network resources. A method for managing network resources is also disclosed.

Claims

1. A method for managing connection of an electronic mail server to an Internet service provider, said method comprising:

receiving, at the Internet service provider, a registration request and connection needs from the electronic mail server, the connection needs pertain to subsequent connections between the electronic mail server and the Internet service provider;

storing the connection needs at the Internet service provider;

monitoring resource utilization at the Internet service provider;

determining suggested mail transmission times based on the connection needs of the electronic mail server and the resource utilization at the Internet service provider; and

forwarding the suggested mail transmission times to the electronic mail server.

2. A method as recited in claim 1, wherein said method further comprises:

receiving, at the electronic mail server, the suggested mail transmission times from the Internet service provider; and

scheduling the connection times for the electronic mail server to the Internet service provider in accordance with the suggested mail transmission times.

3. A method as recited in claim 1, wherein said method further comprises:

receiving, at the electronic mail server, the suggested mail transmission times from the Internet service provider;

determining, at the electronic mail server, whether to override the suggested mail transmission times obtained from the Internet service provider; and

scheduling the connection times for the electronic mail server to the Internet service provider in accordance with at least one of the suggested mail transmission times and the connection needs of the electronic mail server.

4. A method as recited in claim 1, wherein said method further comprises:

receiving, at the electronic mail server, the suggested mail transmission times from the Internet service provider;

modifying the suggested mail transmission times obtained from the Internet service provider based on the connection needs of the electronic mail server; and

scheduling the connection times for the electronic mail server to the Internet service provider in accordance with the modified suggested mail transmission times.

5. A method for managing connection of an electronic mail server to an Internet service provider, said method comprising:

monitoring resource utilization at the Internet service provider to produce resource utilization information;

receiving, at the Internet service provider, a registration request from the electronic mail server;

forwarding the resource utilization information to the mail server;

receiving, at the electronic mail server, the resource utilization information from the Internet service provider; and

determining connection times for the electronic mail server to the Internet service provider based on the connection needs of the electronic mail server and the resource utilization information provided by the Internet service provider.

6. A method for managing network resources for a network, said method comprising:

monitoring resource utilization of the network to produce resource utilization information;

forwarding the resource utilization information to computers coupled to the network; and

thereafter determining desirable times to transmit data over the network taking into consideration the resource utilization information,

wherein the resource utilization information is maintained in a histogram format.

7. A method as recited in claim 6, wherein the network is the Internet.

8. A method as recited in claim 6, wherein the resource utilization information is maintained in the histogram format at predetermined time intervals.

9. A method as recited in claim 6, wherein said method further comprises:

transmitting data over the network in accordance with the determined desirable times.

10. A computer system connectable to a network, said computer system comprising:

a network interface, said network interface operates to connect said computer system to the network;

a data storage device, said data storage device stores network resource utilization information obtained from the network via said network interface;

a processor, said processor executes computer instructions and controls input/output operations, said processor also determines desirable times to transmit data over the network taking into consideration the resource utilization information and then transmits data over the network at the desirable times via said network interface,

wherein the resource utilization information is maintained in a histogram format.

11. A computer system as recited in claim 10, wherein the resource utilization information is maintained in the histogram format at predetermined time intervals.

12. A computer readable medium containing program instructions for managing connection of an electronic mail server to an Internet service provider, said computer readable medium comprising:

computer readable code devices for receiving, at the Internet service provider, a registration request and connection needs from the electronic mail server, the connection needs pertain to subsequent connections between the electronic mail server and the Internet service provider;

computer readable code devices for storing the connection needs at the Internet service provider;

computer readable code devices for monitoring resource utilization at the Internet service provider;

computer readable code devices for determining suggested mail transmission times based on the connection needs of the electronic mail server and the resource utilization at the Internet service provider; and

computer readable code devices for forwarding the suggested mail transmission times to the electronic mail server.

13. A computer readable medium as recited in claim 12, wherein said computer readable medium further comprises:

computer readable code devices for receiving, at the electronic mail server, the suggested mail transmission times from the Internet service provider; and

computer readable code devices for scheduling the connection times for the electronic mail server to the Internet service provider in accordance with the suggested mail transmission times.

14. A computer readable medium containing program instructions for managing connection of an electronic mail server to an Internet service provider, said computer readable medium comprising:

computer readable code devices for monitoring resource utilization at the Internet service provider to produce resource utilization information;

computer readable code devices for receiving, at the Internet service provider, a registration request from the electronic mail server;

computer readable code devices for forwarding the resource utilization information to the mail server;

computer readable code devices for receiving, at the electronic mail server, the resource utilization information from the Internet service provider; and

computer readable code devices for determining connection times for the electronic mail server to the Internet service provider based on the connection needs of the electronic mail server and the resource utilization information provided by the Internet service provider.

15. A computer readable medium containing program instructions for managing network resources for a network, said computer readable medium comprising:

computer readable code devices for monitoring resource utilization of the network to produce resource utilization information;

computer readable code devices for forwarding the resource utilization information to computers coupled to the network; and

computer readable code devices for thereafter determining desirable times to transmit data over the network taking into consideration the resource utilization information,

wherein the network is the Internet and the resource utilization information is maintained in a histogram format at predetermined time intervals.

16. A computer readable medium as recited in claim 15, wherein said computer readable medium further comprises:

computer readable code devices for transmitting data over the network in accordance with the determined desirable times.
