Troubleshooting Layer 2 Ethernet Problem: Loop, Broadcast, Security
Network loops are also known as Layer 2 switching loops or bridge loops, because they occur at Layer 2. Put simply, a loop occurs when a network is cabled in a way that allows traffic to get to a destination by multiple paths. How to handle the troubleshoot layer 2 ethernet problem? we discussed on […]
Up and Running SSH Service
The SSH server usually comes up as a readily installable package on most linux distributions. However, it is not always installed by default. You can try ssh localhost to test if it is running; if it respons with something like Connection refused, then it is not running. How to run SSH Service? we discussed on this webinar series […]
Up and Running DNS Service
A DNS query may return different results based on the namespace of the pod making it. DNS queries that don’t specify a namespace are limited to the pod’s namespace. Access services in other namespaces by specifying it in the DNS query. Every Service defined in the cluster (including the DNS server itself) is assigned a […]
Provide Internet Services Using GPON
GPON stands for Gigabit Ethernet passive optical network (PON). GPON uses Asynchronous Transfer Mode (ATM) for voice, Ethernet for data, and proprietary encapsulation for voice. This means that it uses fixed-sized cells instead of variably sized packets of data. It offers faster Gbps than EPON (Ethernet passive optical network) on downstream and upstream bandwidths How its work? we […]
Telecommunication Evolution
In the telecom world, services have usually been conceived with a specific mindset. This mindset has defined the traditional characteristics of these services; services distinguished by their linkage with the access network, tight control over service use (e.g., authentication, billing), lack of deep personalization capabilities (mass services only) and reliance on standardization to achieve end-to-end […]

Building Local-loop Services for Customers
The local loop is commonly viewed as the connection between the subscriber’s home or office and the nearest exchange. For purposes of interconnection, the switch is the gateway to the local loop for new entrants and would therefore be defined as part of the local loop. How its work? we discussed on this webinar series […]
Socket Programming with Python
Sockets and the socket API are used to send messages across a network. They provide a form of inter-process communication (IPC). The network can be a logical, local network to the computer or one that’s physically connected to an external network, with its own connections to other networks. The obvious example is the Internet, which you […]
Networking in Telecommunication (signalling, tcp, ucp, ss7, sctp, sigtran)
A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals. How does it work? we discussed on this webinar series Webinar topic: Networking in Telecommunication (signalling, tcp, ucp, ss7, sctp, sigtran) Presenter: Jemmy Susanto (Core Network SDM Engineer, Malaysia) Moderator : Achmad Mardiansyah […]
