Abstract

A system and method for topology constrained Quality of Service (QoS) provisioning between a plurality of sites in a Virtual Private Network (VPN) is disclosed. The method comprises enabling graphical definition of relationships between the plurality of sites of the VPN and enabling graphical definition of at least one QoS rule for at least one pair of sites of the plurality of sites of the VPN based at least in part on the defined relationship.

Claims

1. A method for provisioning Quality of Service (QoS) of a plurality of sites of a Virtual Private Network (VPN), comprising:

enabling graphically defining of relationships between said plurality of sites of said VPN; and

enabling graphically defining of at least one QoS rule for at least one pair of sites of said plurality of sites of said VPN based at least in part on said defined relationship.

2. The method of claim 1, wherein enabling graphically defining of at least one QoS rule comprises enabling graphically specifying at least one policing rule between at least said pair of sites.

3. The method of claim 1, wherein enabling graphically defining of at least one QoS rule comprises enabling graphically specifying at least one differentiated services (DiffServ) rule between at least said pair of sites.

4. The method of claim 3, further comprising updating said at least DiffServ rule by dragging and dropping a preconfigured DiffServ template on a graphical link between said pair of sites.

5. The method of claim 3, further comprising displaying a dialog box for updating said DiffServ rule in response to selection of a graphical link between said pair of sites.

6. The method of claim 2, wherein enabling graphically specifying at least one policing rule comprises graphically specifying at least one parameter selected from the group consisting of an ICR (Ingress Commit Rate), an IPR (Ingress Peak Rate), an ECR (Egress Commit Rate), an EPR (Egress Peak Rate), an ICTBS (Ingress Commit Token Bucket Size), an IPTBS (Ingress Peak Token Bucket Size), an ECTBS (Egress Commit Token Bucket Size) and an EPTBS (Egress Peak Token Bucket Size).

7. The method of claim 3, wherein enabling graphically specifying at least one DiffServ rule comprises graphically specifying at least one parameter selected from the group consisting of a Differentiated Services Code Point (DSCP) map and a set of characteristics of an Internet Protocol (IP) header.

8. The method of claim 3, wherein enabling graphically specifying at least one DiffServ rule comprises graphically specifying a set of characteristics of an Internet Protocol (IP) header, said set comprising a protocol, an address of a first site of said pair of sites, an address of a second site of said pair of sites, a port of a first site of said pair of sites, and a port of a second site of said pair of sites.

13. The system of claim 1, said graphical user interface further comprising a dialog box for updating said Diffserv rule in response to selection of a graphical link between said pair of sites.

9. A system for provisioning Quality of Service (QoS) of a plurality of sites of a Virtual Private Network (VPN), comprising:

a graphical user interface, comprising;

a display area graphically displaying at least one VPN component of said VPN;

a customer area displaying said plurality of sites, at least one of said plurality of sites operable to be dragged from said customer area to said display area, wherein dropping of said at least one site on a graphical representation of said at least one VPN component causes said at least one site to be displayed in said display area and to become a member of said VPN component; and

means for graphically defining at least one QoS rule for at least one pair of sites of said plurality of sites of said VPN based at least in part on a membership of said pair of sites.

10. The system of claim 9, wherein said means for graphically defining at least one QoS rule comprises means for graphically specifying at least one policing rule between at least said pair of sites.

11. The system of claim 9, wherein said means for graphically defining at least one QoS rule comprises means for graphically specifying at least one differentiated services (DiffServ) rule between at least said pair of sites.

12. The system of claim 11, further comprising means for dragging and dropping a preconfigured DiffServ template on a graphical link between said pair of sites to update said at least one DiffServ rule.

15. The method of claim 14, wherein enabling graphically defining of at least one QoS rule comprises:

enabling graphically specifying at least one policing rule between at least said pair of sites; and

enabling graphically specifying at least one differentiated services (DiffServ) rule between at least said pair of sites.

14. A method for provisioning Quality of Service (QoS) of a plurality of sites of a Virtual Private Network (VPN), comprising:

graphically displaying at least one VPN component of said VPN;

enabling dragging of a representation of at least one site of said plurality of sites towards said at least one VPN component;

enabling dropping of said representation of said at least one site on said representation of said at least one VPN component thereby causing said site to become a member of said VPN component; and

enabling graphically defining of at least one QoS rule for at least one pair of sites of said plurality of sites of said VPN based at least in part on a membership of said pair of sites.
