Network Management, MIBs and MPLS

Given the financial strain that most companies find themselves under today, it is crucial to be able to manage large, complex networks in an efficient and cost effective manner. This book focuses on the components of network management system technology. Morris focuses on the use of MIBS (management information bases), which monitor network management devices across an entire network remotely and gather stats from these devices in order to make informed decisions regarding network traffic management and application deployment. The book goes on to discuss both enterprise and service provider networks and their associated management problems. Networks are growing rapidly and carrying both mor traffic and different types of real time/non-real time traffic. Network devices are also becoming increasingly complex, providing support for millions of managed objects such as virtual connections. Scalability is probably the biggest single problem facing network managers. Various methods of tackling scalability issues are discussed including pushing more management intelligence into network devices. The author illustrates proposed solutions in practical examples written in Visual C++ and Java.

Network Management, MIBs and MPLS: Principles, Design and ImplementationStephen MorrisEfficiently manage large, complex, multi-service networks Proposes solutions to difficult network management problems Uses practical examples in Java and C++ Covers both enterprise and service provider networksCost-efficiently manage and troubleshoot your MPLS network with SNMP!In today's business world, it is crucial to be able to manage large, complex networks in an efficient and cost-effective manner. Network Management, MIBs and MPLS: Principles, Design and Implementation makes such management possible. Widely-experienced engineer and network management specialist Stephen Morris discusses how, the skillful use of MIBs (management information bases) and network management system (NMS) technology, can be used to help solve some of the management problems associated with running large footprint enterprise and service provider networks. These problems include issues of wide technology mix (ATM, FR, Ethernet, IP, MPLS etc.), the increasing need for real time IP traffic, the need for strong security, scalability (the latter is possibly the biggest single problem facing network managers).With examples in both Java and C++, this book covers SNMPv3, network management software components, IP routing, MPLS and much more. Coverage includes:In-depth analysis of SNMP, the de facto network management standard Scalability solutions using special MIB features, NMS and MPLS HP's Openview Network Node Manager Network management server components NMS software components Case studies in MPLS network management using the IETF MPLS MIBs The theory and practice of network management Numerous reference appendices featuring over 20 pages of C++ and Java source code designed to clearly illustrate the rudimentary structure of an NMSFor networking professionals, network managers, MIB authors and anyone associated with programming for large-scale networks, Network Management, MIBs and MPLS: Principles, Design and Implementation is a vital handbook.
