This paper mainly studies the distributed OSPF protocol implementation in ForCES architecture. The Centralized control plane in ForCES architecture has a certain limits. So, it is significant to study the distributed protocol to satisfy the needs of future network. So I suggest two models for the distributed OSPF protocol in ForCES architecture, At last I test and analyze the distributed OSPF. The...
Open programmable network architecture which based on ForCES is one of the important research on the develop of next-generation network equipment. In this paper, we have studied the transaction management in ForCES channel. First, we have detail introduced the distributed transaction management structure and process in ForCES router. And second, we have built the Petri net model of the communicate...
ForCES(Forwarding and Control Element Separation)-based router (ForTER) can be well positioned to meet the requirements (include openness, scalability, flexibility, etc.) of next generation routers. Due to the separation of Forwarding Element (FE) and Control Element (CE), the ForTER interfaces at FE site, which act as traditional router interfaces, are not directly visible to CE-site routing applications...
This paper presents an inter-FE topology discovery technology on ForCES router, it introduced a new type of topology discovery protocol ITDP (Inter-FE Topology Discovery Protocol). ITDP broadcast the prescribed format of the ITDP packets to each ITDP protocol port when FE is initialized, adjacent FE put these information into a neighbor table after the receipt of ITDP message packet, constructed FE...
Forwarding and control element separation (ForCES) architecture network devices can satisfy the requirements of reconstruction for the new generation of the Internet better. This paper proposes a novel synthetic network management model based on ForCES. This model regards the device under management (DUM) as forwarding element (FE) in ForCES architecture and uses FE model to abstract the definition...
Forwarding and control element separation (ForCES) architecture network devices can satisfy the requirements of reconstruction for the new generation of the Internet better. In this paper, the author proposes a design method of synthetic network management based on Forces protocol. This design method regards the managed devices as forwarding element (FE) in Forces architecture and uses management...
As a reaction to the threat of network security, the appliance of virtual private network (VPN) has become more and more prevalent. In order to support IPSec VPN on ForTER, the paper proposes an implementation model by IPSec security policy LFB, which is the critical step to achieve IPSec VPN on ForTER. Experiment results show the feasibility and effectiveness of the model.
ForCES brings flexible, programmable, and cost-effective advantages over traditional architectures. This paper presents an implement of ForCES-based IPsec VPN SML, which helps users to manage and configure IPsec information. We illustrate the design of IPsec VPN SML, and describe the IPsec-related LFBs. Then we focus on the implement, mainly the realization of SAD and SPD. Finally, we test our works...
Operation management platform (OMP) is the hotspot of research for the prototype of ForCES routers. This paper presents an analysis and evaluation of the message transmission mechanism in OMP. First, we construct an experimental environment and analyze some commonly-used message transmission mechanisms on Web application. Furthermore, according to the main requirements and characteristics of messages...
ForCES (forwarding and control element separation) and the associated protocols introduce a new architecture for construction of a distributed network element (e.g., distributed routers). ForCES requirement indicated that ForCES must support standard network management (e.g., SNMP) in ForCES framework. In this article, an efficient way to support SNMP in ForCES is proposed. On the other hand, as a...
This paper presents a distributed routing algorithm based on architecture of Forwarding and Control Element Separation(ForCES). On this algorithm the calculating routing table divides into two parts, inner routing table between Forwarding Elements and outer routing table between routers. Then according to both routing tables the Control Element calculates the final routing table of each Forwarding...
IETF ForCES (forwarding and control element separation) is defining specifications for interfaces and modular resources abstractions of network equipments. ForCES brings flexible, programmable, and cost-effective advantages over traditional architectures for network equipments. In this paper, the design and implementation of a ForCES-based router (ForTER) was illustrated. The framework of ForCES was...
