 active VM are discarded. This allows the standby VM to safely roll back and restart its processing without creating conflicting results to network clients. Any new network egress traffic is again buffered until the next checkpoint cycle ‘commit’ allows them to be released. Broadband wireless is expected to be one of the main drivers of the telecommunications industry. There is a substantial increase in demand for broadband connectivity, with personal broadband being the key growth engine for mobile wireless broadband networks.
Communication in such networks is generally divided between access and backhaul. An access network is the air interface network providing traffic communication between mobile terminals (subscribers) and their associated access points (base stations), while a backhaul network is the air interface network providing traffic communication between the various base stations and a core network. The networks may be arranged to transfer data alone, as in Wi-Fi networks, or may be arranged for triple play services video, audio and data), typically WiMax (or other competitive technology, such as 3GPP-LTE). In conventional systems, the access network and the backhaul network each require their own separate transmission equipment, antennas, etc. at great cost to the operator.
One example of a conventional backhaul network is connecting wireless base stations to corresponding core mobile networks (ASN GateWay, AAA servers, etc). The choice of backhaul technology must take into account such parameters as capacity, cost and coverage. Base station backhaul typically is performed via wired infrastructure (e.g., E1/T1 leased lines), or via wireless Point-to-point (PTP) microwave links to each base station, which is expensive to deploy (equipment and installation). In particular, due to the direct, uninterrupted line-of-sight requirements of the wireless backhaul equipment, the backhaul components of conventional base stations require strategic deployment location on high and expensive towers.
Mobile WiMAX, as defined in IEEE Standard 802.16e-2005 Standardization for WiMAX, was originally designed to provide mobile broadband access for mobile devices, i.e., broadband wireless data-optimized technology, providing carrier-grade triple play services using a variety of user devices (such as laptops, PDAs, handheld devices, smart phones, etc.). A complete mobile WiMAX Radio Access Network (RAN) requires deployment of massive infrastructure, including base station sites with high towers, base station equipment, antennas, and a separate backhaul network, as described above.

Any raw network egress dealings is again buffered until the next checkpoint cycle ‘ commit ’ allow them to be released. Broadband wireless is expect to be one of the main drivers of the telecommunication diligence. There is a substantial addition in demand for broadband connectivity, with personal broadband being the cardinal emergence engine for mobile wireless broadband networks. 
 Communication in such network is generally divided between entree and backhaul. An access net is the air interface network providing traffic communication between mobile terminals (subscriber) and their associated access points (base stations), while a backhaul network is the air interface network providing traffic communication between the various base stations and a core network. The networks may be arranged to transplant data alone, as in Wi - Fi net, or may be stage for triple play services video, audio and data), typically WiMax (or other competitive engineering, such as 3GPP - LTE). In conventional systems, the access network and the backhaul network each require their own separate transmission equipment, antennas, etc. at great cost to the operator. 
 One case of a conventional backhaul net is connect wireless base stations to corresponding effect mobile networks (ASN GateWay, AAA servers, etc). The option of backhaul technology must assume into account such parameters as capacitance, cost and coverage. al-qaeda station backhaul typically is performed via pumped-up infrastructure (e.g., E1 / T1 leased lines), or via wireless Point - to - point (PTP) microwave link to each base place, which is expensive to deploy (equipment and installation). In particular, due to the lineal, uninterrupted line - of - sight requirements of the wireless backhaul equipment, the backhaul components of conventional base stations require strategic deployment location on high and expensive towers. 
 Mobile WiMAX, as specify in IEEE Standard 802.16e-2005 Standardization for WiMAX, was originally designed to supply mobile broadband access for mobile devices, i.e., broadband wireless data - optimized engineering, providing carrier - grade triple play services using a variety of exploiter device (such as laptops, PDAs, handheld devices, smart phones, etc .). A accomplished mobile WiMAX Radio Access Network (RAN) requires deployment of massive infrastructure, including base post sites with high towers, base station equipment, antenna, and a separate backhaul network, as described above.
