1. A method of redirecting network traffic at an intermediate network device, the redirecting to a destination other than an intended final destination, comprising:
- receiving, from a first network element, traffic intended for the intended final destination network element;
introducing a modification to the traffic by rewriting IP packet header information in the traffic, the modification based on a quality of service rights profile associated with the first network element and maintained at the intermediate device; and
based on the modification, redirecting the modified traffic to an alternate final destination network element other than the intended final destination network element.

Abstract
Systems and methods for redirecting network traffic are described, in which network traffic originating from a first network element and initially intended to be received at a first destination network element is modified by, for example, rewriting the Type of Service field of an Internet Protocol packet, and as a result the modified traffic is redirected to a second final destination network element.

12. A system to redirect Internet traffic at an intermediate network device, the redirecting to a destination other than an intended final destination, comprising:
-
a first arrangement to receive from a first network element traffic intended for the intended final destination network element, and to introduce a modification to the traffic by re-writing IP packet header information in the traffic, the modification based on a quality of service rights profile associated with the first network element and maintained at the intermediate device; and a second arrangement to redirect the modified traffic to an alternate final destination network element based on the modification other than the intended final destination network element. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
