ATM. Therefore, for telecom networks, ATM is ideal as a multi-service platform for a period of time. Even in the foreseeable future, at the edge of the network, ATM is still indispensable as a business collection point. For this reason, many ATM manufacturers are still trying to improve the performance and capacity of the ATM switch, so that it has a place in the next generation telecommunications network.
There are two ways to combine ATM and IP. The first is overlap between the two. Although
interconnection problem between manufacturers is solved, the softswitch classification or full-plane routing mode can be gradually introduced.
2.2 Traffic Network Design
Due to the adoption of the Fast IP forwarding technology, the soft-switch route organization is flat and connectionless. QoS and security should be considered in the design of the traffic network. Currently, the IP bearer network is mainly implemented using mpls vpn technology. To ac

With the advancement of FTTx, on the one hand, the traditional leased line service is also faced with the dilemma of the ATM switch return. A large number of leased line services need to be accessed with high quality and quality. If a single access is built to carry this service, it will bring a huge burden to operators. On the other hand, the traditional DSLAM mode service configuration mainly uses VLAN configurat

At present, the development of Ethernet switches is very rapid. Here we analyze the development status of Ethernet switches. MPLS switches follow the trend of combining ATM and IP addresses. Multiprotocol Label Switching (MPLS) is a tag exchange technique between Layer 2 and Layer 3. It is specially designed for IP addresses, the high-speed switching capability of the second layer can be combined with the f
Ethernet switches are still commonly used. So I studied the market development and future directions of Ethernet switches. I would like to share with you here, hoping to help you.

There are many ways to access the broadband network. At the same time, these methods also use different access technologies. Each new technology can solve the problem that the old technology cannot implement, here we will introduce the features and principles of these technologies.

Since June, China Telecom has opened a VPN service for major customers on the newly created CN2, marking the maturity of a new IP bearer network. This bearer network not only adopts the latest technologies

In general, service providers focused on the security field typically offer high-end solutions that are positioned on large enterprise customers both in terms of design and product pricing. So for smaller companies, they have to develop and maintain their own network security solutions or buy services from local resellers so they don't know exactly how well their networks can be secured.

Such as Cisco label exchange TAG Swiching, Ipsilon IP address exchange, and Toshiba Cell Exchange Router CSR: Cell Switching Router) and IBM's ARISAggregate Route based IP Switching), and IETF's Multi-Protocol Label Switching MPLS: Multi-Protocol Label Switching.

VPN technology-P, PE, CE what is P, PE, cempls vpn there are three types of routers, CE router, PE router and P router. The CE router is a client router that provides you with a connection to the PE router. The PE router is the operator's edge router, that is, the Label Edge Router (LER) in the MPLS network ), it processes the VPN data from the CE router or the label exchange path (LSP) based on the stored route information and forwards the data.

With the rapid development of Internet and optical fiber technology, the integration of IP and Optical network technology will become an important trend of network development in the future. How to solve the integration of IP layer and optical layer, GMPLS provides a good idea. Gmpls inherits almost all MPLS features and protocols, and is an extension of MPLS to optical network, it can use u
Multi-Protocol label switching (MPLS)
In traditional 3-tier forwarding, each router extracts forwarding information from a 3-tier file header as packets are transmitted over the network. This file header analysis is repeated for each router that the packet passes through.
In MPLS networks, packets are forwarded according to the label. Each IP network that can be reached through an interface is assigned a
