A method for preventing a dirty virtual machine from executing on an undesirable host server includes receiving, by a caching module provided for a first host server that hosts a virtual machine, a write data that is of the virtual machine and that is to be cached for the first host server. The virtual machine uses a virtual hard disk supporting hyper-V Virtual hard disk (VHDX) and virtual hard disk (VHD) file formats or any virtual file format with uniquely identifiable metadata. In response to the receipt of write data, the caching module provided for the first host server changes metadata of virtual hard disk files to a custom format before the virtual machine migrates from the first host server to a second host server, and the virtual machine becomes dirty as a result. When the dirty virtual machine sends a migration request to the second host server, a caching module provided for the second host server checks whether the custom format of the virtual hard disk files is identifiable. If not, then the second host server rejects the migration request initiated by the virtual machine.

A method and system of bearer management signalling in a communication network comprising of transporting bearer resource request message of both the UE and RN via DeNB to managing entity of UE within EPC, as a signalling message over uplink channel referred to as 'Union of Resource Request' (UR Request)' message. The bearer resource response message from one of the managing entity of UE or managing entities of UE and RN within EPC are transported as a signalling message to Evolved Packet Edge (EPE) via DeNB over the downlink channel referred to as 'Independent Admission Response' (IA Response). This manages bearer setup signalling as a single loop, by transportation of &#x201c;UR Request&#x201d; signalling message over uplink and receiving one &#x201c;IA Response&#x201d; signalling message over downlink channels. EPE is a conglomeration of network nodes comprising of UEs, RNs and all other network nodes that communicate over EPC via DeNB.

The present invention provides a protection switching method of a node having communication failure in a ring, in a communication network. In one embodiment, this is accomplished by checking for loss of signal (LOS) at the non-ERPS device or at least one of the node in a communication channel, checking periodically for Continuity Check Message (CCM) at both the node, wherein the CCMs are periodically transmitted from both the node through at least one non-ERPS device, appropriately setting a Remote Destination Indication (RDI) bit in the Continuity Check Message (CCM) generated from at least one node and transmits the same via the non-ERPS device or through the non-ERPS device or through a disjoint communication channel, and blocking port of the node towards the non-ERPS device upon receipt of the fault notification and transmitting signal fail notification message on both the ports in the ring.

The present invention provides a method and system for preventing MAC address learning in Provider Backbone Bridge Network (PBBN). In one embodiment, this is accomplished by receiving data frames from at least one operator/client at the first PBB network which has to be communicating to the second PBB network, adding forward path learning information from the received data frames in the first PBB network and translating backbone MAC source address of the received data frame at the first PBB network by replacing the backbone MAC source address with a BEB backbone MAC address, thereby preventing of backbone MAC address learning of the first PBB network in the second PBB network.

Intersection signaling method for bearer management in a communication network with transporting bearer resource request message of both the UE and RN via Base station to managing entity of RN within EPC, as a signaling message over uplink channel referred to as 'Union of Resource Request (UR Request)' message. The bearer resource response message from one of the managing entity of UE or managing entities of UE and RN within EPC are transported as a signaling message to Evolved Packet Edge (EPE) via Base station over the downlink channel referred to as 'Intersection of Admission Response (IA Response)'. This manages bearer setup signaling as a single loop, by transportation of &#x2018;UR Request&#x2019; signaling message and receiving one 'IA Response' signaling message over uplink and downlink channels respectively. EPE is a conglomeration of network nodes.

A network topology including at least one protection infrastructure segment for each work infrastructure segment, such that the work infrastructure segment and the corresponding protection infrastructure segment terminate on the same nodes, wherein the two protection infrastructure segments pass through at least one bridge node, monitoring for failure in the work and protection infrastructure segment in the network, switching Traffic Engineered Service Instance (TESI) over high priority protection infrastructure segment, and provisioning two SPG of co-joint node to prevent infrastructure segment from forwarding ambiguity and retracing of the TESI.
