Enterprise Session Border Controller; a Network Element Deployed to Protect SIP based VoIP networks

Enterprise Session Border Controller Market



 An enterprise session border controller (E-SBC) is a device that regulates and protects data streams as they traverse the boundaries of a network. It is specifically designed to address unique security, reliability, and interoperability problems that can occur when real-time communications sessions across network borders. Enterprise session border controllers control and secure VoIP (voice over IP) and other forms of communication, such as video conferencing, unified communications, and messaging. SBCs also control, measure, and protect VoIP sessions as they pass through a network, from one edge of the network to the other.

A session border controller is a special-purpose device that protects and regulates IP communications flows. They are deployed at network borders to control IP communications sessions. SBCs act as a router between the network and the carrier service ensuring that all calls are secure and have the highest quality of service possible. An SBC can also serve as an additional firewall that can identify incoming threats. Enterprise Session Border Controller is a network function that secures voice-over IP (VoIP) infrastructures while providing interworking between incompatible signaling messages and media flows (sessions) from end devices or application servers.

Session border controllers provide a variety of functions for their host networks, such as security, network connectivity, quality of service, and regulatory and media services management. It also serve as a gateway to and from the public Internet and is an essential component of cloud-based unified communications solutions. It is often used to secure SIP based voice over Internet Protocol (VoIP), also known as IP telephony, organizations. Enterprise session border controller (E-SBC) acts as a segregation point between Voice over IP (VoIP) network of businesses and the session initiation protocol (SIP) trunk of the service provider.

Session border controllers play a vital role in the VoIP system and are vital for a well-functioning IP communication system. Without SBCs, enterprises or organizations might experience security issues and communication interruptions rather than save a fortune in the long term. Session border controller lets enterprise interconnect SIP trunks, on-premise enterprise telephony, Contact Center as a Service (CCaaS), Unified communications as a service (UCaaS), and any other SIP service with security, reliability, quality, and scalability that enterprises can deploy in their own networks. Thus, there is an increase in demand for SBCs in enterprises.

In February 2023, Microsoft partnered with selected Session Border Controllers (SBC) vendors to certify that their SBCs work with Direct Routing. A certification covers comprehensive validation of the SBC for the Azure direct routing.

Micro-mobility Charging Infrastructure: Enabling the Growth of Shared Electric Transportation

Image
Micro-mobility Charging Infrastructure Micro-mobility modes like e-scooters and e-bikes are growing rapidly as a means for short urban trips. However, a critical factor in expanding their use is developing robust charging infrastructure to power these shared electric vehicles. An optimized charging network can help micro-mobility services scale up reliably while reducing their environmental impact. Charging Operations Managing large fleets of chargers and ensuring electric Micro-Mobility Charging Infrastructure  power requires efficient charging logistics. Companies operate networks of dedicated chargers that scooters and bikes can be docked at for a quicker recharge compared to slower at-home charging. Charging stations are usually located near high traffic areas like transit stations or parks to maximize accessibility and convenience for riders. Chargers may be owned by operators or deployed through partnerships with property owners at locations like parking garages, offices an

The Innovative Distributed Ledger Technology - Hashgraph

Image
Hashgraph What is Hashgraph? A hashgraph is a data structure used in distributed ledger technology that facilitates fast and fair transactions without the need for mining or blocks. It is an alternative to blockchain that aims to improve performance, fairness and security through its unique gossip-about-gossip protocol. Rather than recording transactions in a linear blockchain, hashgraph transactions are ordered in a directed acyclic graph (DAG) structure. When a transaction is received by a node, it is gossiped to other nodes to be added to their local ledger with a digital signature as proof. Nodes then gossip among each other to achieve consensus on the transaction order without the energy-intensive mining process used in blockchains. The gossip-about-gossip protocol At the heart of hashgraph is its gossip-about-gossip protocol which allows nodes to communicate efficiently and achieve immediate consensus. When a transaction occurs, it is broadcast from the node that created it

Salt Substitutes: Healthier Alternatives for your Daily Diet

Image
Salt Substitutes Salt is a necessary part of our diet and helps regulate fluid balance in the body. However, most people consume far more salt than the recommended daily limit of 2300mg. Excess salt intake is linked to high blood pressure and increased risk of heart disease and stroke. If you want to cut back on salt but still enjoy flavorful foods, salt substitutes provide a healthier alternative. What are Salt Substitutes? Salt substitutes aim to mimic the taste of salt without the negative health effects of sodium. They contain little to no sodium but instead use potassium chloride or herbal extracts to enhance flavor. Some common salt substitute ingredients include: - Potassium chloride: The primary ingredient in many salt substitutes. It tastes similar to table salt but contains potassium instead of sodium. Potassium helps counteract the effect of sodium and lower blood pressure. - Herbs and spices: Various herbs, spices and seasonings are used to round out the flavor profi
