What is GMRE in networking?
Participants are introduced to the GMPLS protocol, architecture, and control plane features. This course introduces the skills and knowledge required to control and manage optical networks using the Nokia GMPLS routing engine implementation (GMRE).
Is MPLS connection oriented?
Multi-Protocol Label Switching (MPLS) provides a mechanism for forwarding packets for any network protocol. However, unlike traditional IP, MPLS flows are connection-oriented and packets are routed along pre-configured Label Switched Paths (LSPs).
What is the difference between ill and MPLS?
1.An MPLS and a leased line provide WAN connectivity. 2. The main difference is that an MPLS, if desired, can be implemented as full mesh, while a leased line connects two sites. A leased line is an end user solution, while an MPLS is a complex framework of functions.
Who uses MPLS?
In practice, MPLS is mainly used to forward IP protocol data units (PDUs) and Virtual Private LAN Service (VPLS) Ethernet traffic. Major applications of MPLS are telecommunications traffic engineering, and MPLS VPN.
What do you need to know about GMPLS control?
This course is designed for network engineers, IT personnel, and network planning personnel who need to learn the principles and best practices related to optical network control based on Generalized Multi-Protocol Label Switching (GMPLS). Participants are introduced to the GMPLS protocol, architecture, and control plane features.
What kind of addressing scheme does GMPLS Uni use?
The GMPLS UNI assumed a flat addressing scheme between the UNI-C nodes and the optical network. In this model, a common addressing scheme is used between the UNI-C (IP router) and UNI-N (optical edge). The UNI-C and UNI-N must be in the same subnet.
What kind of IP address does gmre node use?
GMRE node IP— This is the IP loopback address used for GMPLS protocols such as LMP and RSVP. IPCC IP address (also known as DcnGatewayAddress)— This is the source/destination address for IPCC maintenance messages such as LMP hellos and LMP config messages.
Why is GMPLS important to the optical network?
The Generalized Multi-Protocol Label Switching (GMPLS) User to Network Interface (UNI) permits dynamic provisioning of optical transport connections between IP routers and optical network elements in order to reduce the operational time and administrative overhead required to provision new connectivity.
