Methods and systems for managing relays in LTE based communication networks. Embodiments herein use of a packet handler node and an additional radio interface in the UE, enabling the creation of an overlay network on top of an existing LTE network. The overlay network helps in the transfer of data between the UE and the AS even when the UE is not directly connected to the LTE network by encapsulating the data from the out-of-coverage UE within the IP packet of at least one nearby relay UE connected to the LTE network and is then forwarded to the LTE core network. The out-of-coverage UE uses the additional radio interface to send packets to the relay UE.

The present invention provides a novel method for hierarchy of preplanned protected path for both node and link failure in the realm of Carrier Ethernet Technology. In the event of failure in a hierarchy, the traffic is switched from work (primary) path to protected (secondary) path. If such path does not exist within a given hierarchy then traffic is routed through multiple hierarchies until SLA is met or no path exists. Hierarchies make the network fault resilient.

The present invention provides an improved transport protocol for lossy networks. This is accomplished by using computationally efficient techniques to manage invoking congestion control mechanisms to control the transmitted packets in lossy networks. The improved transport protocol receives multiple packets including a header and an associated sequence number. The network is monitored for congestion caused by the received packets and marks the header of some of the packets with an impending congestion indication, based on the outcome of the monitoring. The packets are then transmitted, and a receiver then returns acknowledgements of receipt of each of the transmitted packets. Each of the received acknowledgements includes an associated sequence number and any impending congestion indication assigned to the packet. The protocol monitors each of the received acknowledgements, and based on the outcome of the monitoring, invokes a congestion control mechanism to improve the performance of the transport protocol.
