OSPF (Routing Protocol)

For big networks in the internet what we need is a network path which is shorter and best. OSPF is a routing protocol which enables data packets to choose the best path. It is widely popular IGP (Interior Gateway Protocol) which is implemented by most of the major network providers. OSPF stands for open shortest path first, this protocol determines the best path for routing the data traffic. OSPF does routing based on cost calculation, the path with lowest cost always gets the priority. Consider the example below in this network the lowest cost is 10 hence the packet chooses the path with lowest cost to reach the destination.

IOS 8 for iPhone 4s

Apple has released a new operating system IOS 8, it has new features which are great. But the question remains is it supported by phones of older generations. Well Apple has claimed that ios 8 will be supported by iPhone 6, 6+, 5, 5s and 4s. So is the new operating system up to the mark for the older phones like iPhone 4s. The answer to that question is no, as I have an iPhone 4s and when I upgraded it to ios 8. I got lots of problem after upgrading and the list is as follows.

Communication Technology in Nepal

Nepal is a third world country which is still underdeveloped in terms of infrastructure and poverty. Country is still recovering from a long civil war and the infrastructure development is very slow. The infrastructure in the main cities is also not up to the international standard.  Well that leads us to a big question where does it stand in terms of communication technology?

Voice over LTE

Voice over LTE (Volte) can help you fulfil the vision of portable broadband over LTE, guaranteeing beneficial brilliant voice, feature and interactive media administration to your clients.

Information may overwhelm portable movement, however voice and SMS still speak to more than 70% of specialist income and are the most utilized versatile administrations.

As customers want and request more administrations for less cash, its discriminatingly critical to diminish conveyance costs if administration suppliers are to remain gainful. The adaptability and more excellent range proficiency of Long Term Evolution (LTE) systems gives some piece of the reply.

HSPA (High Speed Packet Access)

HSPA - High Speed Packet Access is the most broadly sent versatile broadband engineering on the planet today and will expand upon the more than 6 billion associations with the GSM group of advances. HSPA is the phrasing utilized when both HSDPA (3gpp Release 5) and HSUPA (3gpp Release 6) advances are sent on a system. HSPA Evolved (Hspa+ in 3gpp Release 7 and past) is additionally some piece of the HSPA engineering and expands a specialist's speculation in the system before the following venture to 3gpp Long Term Evolution (LTE, or 3gpp Release 8 and past). HSPA expands on third era (3g) Umts/wcdma and is determinedly positioned as the heading versatile information engineering for a long time to come.

Long Term Evolution (LTE)

The portable systems of most specialists are seeing a remarkable ascent in information movement, because of an expanding buyer interest to enter data transfer capacity escalated substance on-the-go and the multiplication of countless apparatuses, for example, cell phones and tablets. This pattern is pushing amazingly high weight on the limit compelled system of drivers. Confronted with this test, remote suppliers requirement to overhaul their system foundation to stay aware of information.
