Telco networking products have undergone extremely rapid evolution for the last few decades, since the introduction of IP, then MPLS and Carrier Ethernet, and this trend is continuously accelerating. Network operators are clamoring for these products so they can deliver feature-rich leading-edge services more cost-effectively.
There are a variety of protocols or applications involved, acting in concert with or dependent upon each other: Routing protocols (BGP, IS-IS, OSPF, RIP), Signaling protocols (BGP, LDP), Encapsulation protocols (GRE, IP, L2TP, MPLS), etc. Carrier Ethernet has a whole suite of protocols that operate at layer-2 to provide signaling and operations support (IEEE 802.1Q, IEEE 802.3ah, IEEE 802.1Qay, Metro Ethernet Forum standards, etc.).
These so-called “control-plane” and “data-plane” protocols are augmented by management-plane protocols like FTP, HTTP, SNMP, SSH, TELNET, etc. All of these Mu protocol testing suites also leverage the “plumbing” protocols that must operate correctly in order for the Telco network service to do their jobs: ARP, ICMP (v4/v6), IP (v4/v6), DHCP, DNS, etc.
