The present invention effectively processes the user's demands and demands when allocating resources using virtual concatenation in a multi-service protocol platform (hereinafter referred to as MSPP), and creates a virtual concatenated group by using an idle port. It is about.

MSPP equipment is a next generation networking equipment that can transmit and process various types of data through a single optical transmission device (Synchronous Digital Hierarchy: SDH).

The most important issue in recent years is how to transport IP (Internet Protocol) traffic most efficiently. Since the source data before IP traffic is mapped to the physical layer is composed of various different services through various network layers or mappings, it is impossible to directly transmit Internet data to wavelength division multiplexing (WDM) or wavelength. There are several ways to combine IP and SDH in a data link later. The most common of these are asynchronous transfer mode (ATM), Point-to-Point Protocol (PPP), Multiprotocol Label Switching (MPLS), and the like. The technique of mapping ATMs to SDH's Virtual Containers (hereinafter referred to as VCs) is already well standardized, but the standard does not discuss whether the contents of an ATM cell are IP or any other type of digital signal. If the IP or ATM signals are mapped to the VC of the SDH in an appropriate way, then all signals can be reliably delivered by the transmitting equipment.

Although IP routers and ATM switches are connected by the appropriate interface, they are only point-to-point networks and require additional networks that are dedicated to pure IP / ATM traffic. Given the cost, security, flexibility, interoperability, and transmission latency, the most efficient solution is to adapt the content of data services in the SDH network.

The basic standard that composes MSPP is ITU-T G.7041, Generic Framing Procedure (GFP), which maps packet data to SDH, and utilizes the virtual concatenation specified by ITI-T G.707 to provide efficient bandwidth. Bandwidth management (e.g., mx VC12 (2 Mbps), nx VC3 (45 Mbps), kx VC4 (155 Mbps)) and ITU-T G.7041 Link Capacity Adjustment Scheme (LCAS) support reduced hitless bandwidth growth. These three constitute next-generation SDH / SONET, spanning tree protocol of IEEE 802.3d / w / s, virtual LAN (LAN) of IEEE 802.1p / q, MPLS, ATM, and Digital Video (SDI) of IETF. ) To configure MSPP (Multi Service Provisioning Platform).

1 is for conceptually explaining a virtual connection method according to the prior art. 1, Ethernet packets are mapped to EAST, WEST, and HUB ports, respectively. At this time, each port forms an independent virtual connection. For example, it can provide 3 Mbps for the EAST port, 8 Mbps for the WEST port, and 45 Mbps for the HUB port, but cannot provide services on the selected bandwidth of 3 Mbps, 8 Mbps, or 45 Mbps for the EAST port. As such, as the needs and demands of subscribers grow, the need for a concept of a virtual concatenation group (hereinafter referred to as VCG) that can provide differentiated services for users with different needs increases. However, the related art does not provide an effective solution for this.

The present invention was devised to solve the above problems, and by creating a virtual concatenated group using idle ports in a multiservice protocol platform device, a multiservice protocol platform that can provide differentiated services for users with different needs. An object of the present invention is to provide a method for creating a virtual concatenated group using an idle port in.

In order to achieve the above objects, the method according to the present invention for creating a virtual concatenated group using the idle port of the plurality of ports provided in the multi-service protocol platform equipment, (a) multi-service protocol platform equipment Magnetically looping back an idle port; (b) forming a virtual concatenation by connecting the idle looped idle port between an Ethernet port and a virtually contiguous port in a multiservice protocol platform device; And (c) allocating bandwidth by a virtual concatenation selected from a virtual concatenation group consisting of a virtual concatenation of an existing port and a virtual concatenation of an idle port when bandwidth allocation is required.

Hereinafter, preferred embodiments of the virtual concatenated group generation method using the idle port in the multi-service protocol platform according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating a method of creating a virtual concatenation group by using an idle port that is not used among a plurality of ports provided in a multiservice protocol platform device.

First, as shown in FIG. 3, in the multi-service protocol platform equipment in which the present invention is implemented, a virtual connection 22 is formed from the Ethernet port 10 to the EAST port 20 to provide STM-1 (155 Mbps) service. Suppose you are going. In addition, it is assumed that the existing virtual concatenation 22 of the EAST port 20 provides a service of 3Mbps bandwidth. And, it is assumed that the WEST port and the HUB port are in an idle state.

In such a situation, the idle port of the multiservice protocol platform device is magnetically looped back (S10), and then the magnetic loopbacked idle port is connected between an Ethernet port and a port that is in use virtually in the multiservice protocol platform device. Form a connection (S20). In this way, the virtual concatenation group is created by including the existing virtual concatenation in the newly formed virtual concatenation.

As shown in FIG. 4, a magnetic loopback is formed at the WEST port 30. Then, the input port of the Ethernet 10 is connected to the output port of the WEST 30, the output port of the WEST 30 is connected to the input port of the WEST 30 through magnetic loopback, and the input of the WEST 30 is connected. Connect the port to the output port of EAST (20). In addition, the input port of the EAST 20 is connected to the output port of the WEST 30, the output port of the WEST 30 is connected to the input port of the WEST 30 through magnetic loopback, and the input of the WEST 30 is connected. The port is connected to the output port of Ethernet 10 to form a new virtual concatenation 32. In the new virtual concatenation 32, it is assumed that 8 Mbps bandwidth service is possible.

In addition, as shown in FIG. 5, a magnetic loopback is formed at the HUB port 40. The input port of the Ethernet 10 is connected to the output port of the HUB 40, the output port of the HUB 40 is connected to the input port of the HUB 40 through magnetic loopback, and the input of the HUB 40 is connected. Connect the port to the output port of EAST (20). In addition, the input port of the EAST 20 is connected to the output port of the HUB 40, the output port of the HUB 40 is connected to the input port of the HUB 40 through the magnetic loopback, and the input of the HUB 40 The port is connected to the output port of Ethernet 10 to form a new virtual junction 42. In the new virtual concatenation 42, it is assumed that a service of 45 Mbps bandwidth is possible. Then, a service of a selected bandwidth unit among 3 Mbps, 8 Mbps, and 45 Mbps is possible through the virtual concatenated group as a whole. 6 is a conceptual diagram exemplarily illustrating virtual concatenated group formation using idle ports (WEST port, HUB port) according to the present invention.

Then, when bandwidth allocation is required, if there is an idle bandwidth among the entire bandwidths, if there is an idle bandwidth, a bandwidth suitable for the required bandwidth is selected from the virtual concatenation group, and the link capacity adjustment scheme (LCAS) of the selected virtual concatenation is selected. Bandwidth is allocated by (S30).
