SCTP in Python

I’ve written in the past about SCTP – Stream Control Transmission Protocol, talking about it’s advantages and how to implement it in Kamailio. If you’d like to write your own software using SCTP there’s a fantastic SCTP sockets library from P1 Security that makes this easy as any other socket programming. Take a look at […]

IMTx: NET02x (4G Network Essentials) – Management of Data Flows – 7. NAS and Global View of Protocol Stack

These are my lecture notes from IMT’s NET02x (4G Network Essentials) course, I thought I’d post them here as they may be useful to someone. You can find my complete notes here. The LTE architecture compartmentalises the roles in the mobile network. For example the eNB concentrates on radio connection management, while the MME focuses […]

IMTx: NET02x (4G Network Essentials) – Management of Data Flows – 5/6. S1AP Connection

These are my lecture notes from IMT’s NET02x (4G Network Essentials) course, I thought I’d post them here as they may be useful to someone. You can find my complete notes here. Each MME can manage millions of UEs. To handle this load the requirements of each subscriber for the MME must be as minimal […]

To me Stream Control Transmission Protocol (SCTP) is one of those, and it’s really under-utilised in Voice. Defined by the SIGTRAN working group in 2000 while working to transport SS7 over IP, SCTP takes all […]
