New signaling procedures in ATM networks for advance resource reservation
- 40 Downloads
Currently, communication with resource reservation on ATM networks has been required by popularization of multimedia applications. Types of resource reservation are classified into two types according to reservation timing. One type invokes resource reservation just before communication between users. Another type invokes it in advance. In this type, resources can be reserved with communication time periods invoked by a user, well before actual communication. For the former type, several standardization committees, such as the ATM Forum and ITU‐T, have provided some signaling protocols. However, the latter type has no signaling protocol although necessity of this type has increased. This paper presents approaches of this type at first. Next, it proposes new signaling protocols to support this type keeping consistency with the conventional protocols for the former type, and compares proposed protocols. Moreover, it presents mechanisms to reserve resources cooperating with proposed signaling protocols.
