Claim:
1. A method of media streaming, the method comprising: receiving, at an inter working function (IWF) deployed in a layer2 access network, a first message from a user equipment (UE), the first message comprising a first protocol type; repackaging, by the IWF, the first message into a second message having a second protocol type if the first protocol type of the first message matches a third protocol type and a destination IP address of the first message matches an address in an IP table indicating that content requested by the first message is cached in a local layer3 based media server deployed in the layer2 access network; forwarding, by the IWF, the second message to the local layer3 based media server; determining, by the IWF, whether the local layer3 based media server has failed; and responsive to a determination that the local layer3 based media server has failed, forwarding, by the IWF, the second message to a network component.
