Traffic engineering and server selection for content distribution

摘要

An apparatus comprising a traffic engineering (TE) and server selection (SS) component configured to couple to an SS component and operate at a first time scale based on SS policies from the SS component, wherein the SS is configured to operate at a second timescale based on TE policies from the TE and SS component, and wherein the second timescale has a finer time granularity than the first time scale by at least one order of magnitude. Also disclosed is a network component comprising a receiver configured to receive one or more SS policies from a content provider or customer node, a logic circuit configured to compute a plurality of joint TE and SS policies for a plurality of network nodes based on the received SS policies, and a transmitter configured to send the joint TE and SS components to the content provider or customer node.

1. An apparatus comprising:
a traffic engineering (TE) and server selection (SS) component configured to couple to an SS component and operate at a first time scale based on SS policies from the SS component, wherein the SS component is configured to operate at a second timescale based on TE policies from the TE and SS component, wherein the TE and SS component is further configured to couple to a timer component that is configured to determine the time granularity of the first timescale, wherein the SS component is coupled to an applications component that is configured to receive the SS policies, wherein the second timescale is determined based on requests from the applications component, and wherein the second timescale has a finer time granularity than the first time scale by at least two orders of magnitude.
