Abstract: In one embodiment, a method includes monitoring traffic at a network device at a receiving network site to determine if a performance threshold is violated, transmitting an alert to a sending network site if the performance threshold is violated at a path at the network device, and transmitting traffic information for the path from the network device to the sending network site. The receiving network site comprises a plurality of paths for receiving traffic from the sending network site and traffic information is transmitted to the sending network site for each of the paths if the performance threshold is violated. An apparatus and logic are also disclosed herein.

Abstract: In one embodiment, methods are described to measure bandwidth limits through multiple test sites. A testing quantity of network packets is generated, the network packets are sent through a service provider network to a plurality of receivers at a testing transmission rate that exceeds an upstream transmission rate limit of the service provider network, a report indicating a received number of packets is received from each of the plurality of receivers, and an upstream transmission rate limit of the service provider network is determined based on the testing transmission and the reports. By using multiple test sites, potential bottlenecks at any one test site are reduced. A similar method can be used to calculate a downstream transmission rate limit. Once measured, the bandwidth limits may be used to adjust quality of service on an edge router or compared against a known service level agreement of the service provider network.

Abstract: A STUN message is received at a router device in a network from a client device in the network along a network path. The STUN message is evaluated for information that indicates to the router device to modify media that is subsequently sent along the network path. If the evaluating indicates that the router device is to modify the media, the media is modified in accordance with information in the STUN message that indicates attributes of the network.

Abstract: In one embodiment, two or more links, coupled to a first service provider (SP) that charges a price for utilization of services according to a first pricing structure, are combined to form a single virtual combined link. Each of the two or more links of the virtual combined link and one or more other links, coupled to a second SP that charges a price for utilization of services according to a second pricing structure, are monitored to obtain link data. The link data for the two of more links of the virtual combined link is merged to form link data for the virtual combined link. Data distribution among the virtual combined link and the one or more other links is optimized to distribute data among the virtual combined link and the one or more other links in a manner that minimizes cost.
