Connectivity in IOT

Global IoT market is witnessing an increase in the number of connected devices every year. IoT is now being used across several industries for a wide variety of applications. One of the major part of IoT is connectivity which still is having several issues. IoT network stability and efficiency is very essential for long-term growth of IoT and connectivity vendors are keen on improving it.

Spanning Tree Protocol (STP), a protocol aimed at building a loop-free logical topology for Ethernet networks is used by a huge number of IoT network providers. STP requires lot of changes for improving the network reliability of IoT network. Any failure in STP could lead to complex issues which are not desirable in IoT networks. Many companies fail to configure STP as per industry best practices.

Major network solution providers are planning to replace STP with Multi System Link Aggregation (MLAG) or Shortest Path Bridging (SPB) protocol. While some vendors trust the MLAG for its complete utilisation of bandwidth and cost-effectiveness, some trust SPB for its high reliability and scalability. Vendor’s implementation of MLAG is proprietary since they agree in MLAG concept and disagree about how it should be implemented.  Also, some finds it as a long-term solution while some considers it as a short-term solution until a standard solution is made available. Vendors like HP are supporting both MLAG and SPB standards.


To achieve high scalability and reliability in IoT, vendors must focus on improving protocols and security measures and should educate business leaders regarding the importance of network in their IoT strategy. In addition to the connectivity, network providers must focus on data security models for to fight against cyber-attacks.
