MPLS automatic bandwidth allocation (or provisioning) refers to the process of dynamically updating the bandwidth allocation of a label switched path on the basis of actual aggregate traffic demand on this path. Since bandwidth updates require signaling, it is common to limit the rate of updates to reduce signaling costs. In this article, we propose a model-free asynchronous adaptive hysteresis...

The Link Management Protocol (LMP) is used to coordinate the properties, use, and faults of data links in networks controlled by Generalized Multiprotocol Label Switching (GMPLS). This document defines an extension to LMP to negotiate capabilities and indicate support for LMP extensions. The defined extension is compatible with non-supporting implementations. Information about the current statu...

This document provides an analysis grid to evaluate, compare and contrast the Generalized Multi-Protocol Label Switching (GMPLS) protocol suite capabilities with respect to the recovery mechanisms currently proposed at the IETF CCAMP Working Group. A detailed analysis of each of the recovery phases is provided using the terminology defined in a companion document. This document focuses on trans...

This document provides a framework to allow the development of protocol extensions to support Generalized Multi-Protocol Label Switching (GMPLS) and Path Computation Element (PCE) control of Optical Transport Networks (OTNs) as specified in ITU-T Recommendation G.709 as published in 2012. Status of This Memo This document is not an Internet Standards Track specification; it is published for inf...

From a carrier perspective, the possibility of turning a permanent connection (PC) into a soft permanent connection (SPC) and vice versa, without actually affecting data plane traffic being carried over it, is a valuable option. In other terms, such operation can be seen as a way of transferring the ownership and control of an existing and in-use data plane connection between the management pla...

Packet assembly at the network edge is one solution to reduce high packet rates in core network switches. Literature discusses this topic controversially because of three reasons: (1) potential negative impact of packet assembly on the traffic characteristics, (2) disruptive integration into existing networks and (3) lack of support of packet assembly in existing control plane environment. In t...

Proper functioning of RFC 1191 path Maximum Transmission Unit (MTU) discovery requires that IP routers have knowledge of the MTU for each link to which they are connected. As currently specified, the Label Distribution Protocol (LDP) does not have the ability to signal the MTU for a Label Switched Path (LSP) to the ingress Label Switching Router (LSR). In the absence of this functionality, the ...
